8.7 Event library

This library makes functions available with whose aid events can be recognized and processed. As a rule, program control is released to the operating system until the specified event has occurred. The following routines are available for this purpose:

evnt_button Waits for a mouse button press
evnt_dclick Obtains/alters the double-click response rate
evnt_keybd Waits for a keypress
evnt_mesag Waits for a message
evnt_mouse Waits for a move of the mouse pointer
evnt_multi Reacts to several events
evnt_timer Waits for a timer event
Standard messages  
Message-list Overview of all known messages, including:
Messages from Geneva
RSDAEMON messages

Note: 'event' in this case should be understood as a message, key press, mouse movement and button activation, timer events etc.

8.7.1 evnt_button

Name: »Event button« - Wait for a mouse button event.
 
Opcode: 21
 
Syntax: int16_t evnt_button ( int16_t ev_bclicks, int16_t ev_bmask, int16_t ev_bstate, int16_t *ev_bmx, int16_t *ev_bmy, int16_t *ev_bbutton, int16_t *ev_bkstate );
 
Description: The call evnt_button waits for a button event, i.e. until the mouse buttons specified in ev_bmask are set to the state specified in ev_bstate. More exactly:
 
The function waits until the desired event has occurred once. This is followed by a wait to check if the event is repeated. If the event has occurred ev_bclickstimes or the time set with evnt_dclick has expired), the function returns immediately. The following apply:
 
Parameter Meaning
   
ev_bclicks Maximum number of clicks before returning
ev_bmask A bit-vector, which masks the buttons to wait for with a 1. The following apply:
Bit-0 = Left button
Bit-1 = Right button.
Bit-2 = Middle button, PC-GEM
ev_bstate A bit-vector like ev_bmask, which specifies for each button which state it has to reach before returning. These are:
0 = Not pressed
1 = Pressed
ev_bmx On return, contains the X and
ev_bmy Y coordinate of the mouse pointer at the time the event occurred
ev_bbutton On return, contains the state of the mouse buttons when the event occurred (as in ev_bstate)
ev_bkstate On return contains the status of the 'special' keys of the keyboard when the event occurred:
0x001 = Right [Shift]
0x002 = Left [Shift]
0x004 = [Control]
0x008 = [Alternate]

With a pressed key the corresponding bit will be set

Note: As of PC-GEM/3 the event functions support only one mouse button.
 
Note 2: Specifying both left and right buttons in ev_bmask:
 
ev_button(1,3,3,...
 
will wait until *both* buttons are pressed simultaneously. If you wish to wait for *either* button to be pressed, then you must set bit 8 of *ev_bclicks*:
 
ev_button(0x0101,3,3,...
 
This was documented in the December 1992 issue of ATARI.RSC (the developer's newsletter) and is true for all releases of Atari TOS.
 
Return value: The function returns the number of mouse clicks that were actually made, or, more exactly, the number of times that the mouse button state matched ev_bstate.
 
Availability: All AES versions.

8.7.2 evnt_dclick

Name: »Event double-click« - Obtain or set the time delay between the two clicks of a double-click.
 
Opcode: 26
 
Syntax: int16_t evnt_dclick ( int16_t ev_dnew, int16_t ev_dgetset );
 
Description: The call evnt_dclick sets or obtains the speed with which the double-clicks of the mouse have to be made. The following apply:
 

Parameter Meaning
ev_dnew New speed from 0 (slow) to 4 (fast)
ev_dgetset 0 = Get current value (ignores ev_dnew)
  1 = Set new value

Note: One should always bear in mind that there are people who have problems with too fast a speed, and can then no longer perform double-clicks!
 
The function is also often named evnt_dclicks in older GEM documentation.
 
Return value: The function returns the applicable response rate for double-clicks.

8.7.3 evnt_keybd

Name: »Event keyboard« - Wait for a keyboard event
 
Opcode: 20
 
Syntax: int16_t evnt_keybd ( void );
 
Description: The call evnt_keybd waits for a keyboard event, and returns the corresponding code.
 
Note: Keyboard events are always returned only to the application that 'owns' the active window.
 
With TOS versions from 2.06 and 3.06 onwards, this function is disabled for keys [0] to [9] on the numeric keypad when pressed together with the [Alternate] key. These key combinations allow the entry of the complete range of ASCII values (001 .. 255) by holding down the [Alternate] key while typing in the decimal ASCII-code on the numeric keypad. Without [Alternate] the numeric keypad operates normally.
 
Return value: The function returns in bits 0..7 the ASCII-code, and in the bits 8..15 the scancode of the pressed key.
 
Availability: All AES versions.

Description: The evnt_multi call waits for a number of various events, combining the functionality of evnt_button, evnt_keybd, evnt_mesag, evnt_mouse and evnt_timer in one call. The following apply:
 
Parameter Meaning
   
ev_mflags Desired event:
MU_KEYBD      (0x0001) Keybord event
MU_BUTTON     (0x0002) Button event
MU_M1         (0x0004) Mouse event 1
MU_M2         (0x0008) Mouse event 2
MU_MESAG      (0x0010) Messages
MU_TIMER      (0x0020) Timer events
MU_WHEEL      (0x0040) Mouse-wheel, XaAES
MU_MX         (0x0080) Mouse movement, XaAES
MU_KEYBD4     (0x0100) GEM/4
MU_NORM_KEYBD (0x0100)Normalized key-codes, XaAES
MU_DYNAMIC_KEYBD (0x0200) XaAES, not yet implemented
X_MU_DIALOG   (0x4000) (Geneva)
ev_mbclicks Number of clicks (see ev_bclicks in evnt_button)
ev_mbmask Which mouse buttons should be taken into account (format see ev_bmask in evnt_button)
ev_mbstate Which status the mouse buttons must reach (format see ev_bstate in evnt_button)
ev_mm1flags Should the event be triggered by the entry (0) or leaving (1) of the first rectangle (see ev_moflags in evnt_mouse
ev_mm1x, X-coordinate, and
ev_mm1y Y-coordinate of top L of 1st rectangle (see ev_mox, ev_moy in evnt_mouse)
ev_mm1width Width of the first rectangle (see ev_mowidth in evnt_mouse)
ev_mm1height Height of the first rectangle (see ev_moheight in evnt_mouse)
ev_mm2flags,  
ev_mm2x,  
ev_mm2y,  
ev_mm2width,  
ev_mm2height These are the corresponding parameters for the second mouse event rectangle
ev_mmgpbuff A 16-byte message buffer (see evnt_mesag and ev_mgpbuff)
ev_mtlocount Low-WORD for the timer counter (see evnt_timer)
ev_mthicount High-WORD for the timer counter (see evnt_timer)
Warning: Under TOS 1.0 one may not set the timer in a desk accessory to 0, otherwise the system will hang!
ev_mmox, The X-coordinate, and
ev_mmoy Y-coordinate of the mouse pointer at the occurrence of the event (see evnt_mouse, (MU_WHEEL))
ev_mmobutton Status of the mouse buttons at the occurrence of the event (format see evnt_button)
ev_mmokstate Status of the 'special' keys on the keyboard at the occurrence of the event (format see evnt_button)
For MU_WHEEL: Wheel number
ev_mkreturn Scancode of the pressed key
ev_mbreturn Number of clicks with the mouse button
For MU_WHEEL: Number of wheel rotations

Note: Due to the large number of parameters to be passed this function consumes a relatively large amount of CPU time, since the parameters must first be stored on the stack, and then distributed to the GEM input fields.
 
MU_WHEEL:
This will only be sent if there is not a top window or the top window doesn't have arrow widgets.
 
MU_MX:
This reports ANY mouse movement to the application, (ev_mmox, ev_mmoy), with the state of the keyboard.
 
MU_KEYBD4:
Used internally in GEM/4 to check for a context-sensitive help request.
 
MU_NORM_KEYBD:
If the event mask MU_NORM_KEYBD is passed to evnt_multi the application will receive a normalized key-code (NKCC) instead of the standard AES key-code, together with the state of the mouse. The mask can be used together with MU_KEYBD; if both are passed, then MU_NORM_KEYBD prevails. The normalized key-code is in ev_mmokstate and ev_mkreturn, both having the same value.
 
X_MU_DIALOG:
If the ev_mflags parameter has its bit 14 set, (ev_mflags |= X_MU_DIALOG), then any mouse clicks and keyboard actions within windows containing dialogs will cause the ev_mwhich return value from evnt_multi to have bit 14 set.
When this happens, ev_mmgpbuff WORD 2 contains the index of the object within the dialog which was selected. If the object was a TOUCHEXIT button and the user double-clicked on it, then bit 15 will be set, similar to the way form_do works. WORD 3 of the message buffer ev_mmgpbuff contains the window handle of the window in which the event occurred. This feature is used in conjunction with the wind_set option X_WF_DIALOG.
 
Return value: The function returns the number of the occurring event(s) in the format specified above.
 
Availability: All AES versions.

8.7.7 evnt_timer

Name: »Event Timer« - Wait for a given time interval.
 
Opcode: 24
 
Syntax: int16_t evnt_timer ( int16_t ev_tlocount, int16_t ev_thicount );
 
Description: The call evnt_timer waits until a given time has passed before releasing control to the operating system. The following apply:
 

Parameter Meaning
ev_tlocount Low-WORD of time value in milliseconds
ev_thicount High-WORD of time value in milliseconds

Note: One should always use this function for delay loops in programs. The operating system can then allocate the CPU to another process (even without real multitasking).
 
Under TOS 1.0, neither parameter may be set to 0 for a desk accessory, otherwise the system will hang.
 
This function cannot be relied on as an accurate clock. The specified time is only the minimum time value, with the function returning at some point after this time has passed.
 
Return value: This is always the value 1.
 
Availability: All AES versions.

8.7.8 Messages

Standard messages of the screen-manager are built up as follows:

msg[0] Message type
 
msg[1] Application ID of sender
 
msg[2] Length of additional data; if non-zero, use appl_read to read the additional data. Always 0 in messages sent by the AES.
 

Types of standard messages:

Message Meaning
 
   
 
AC_CLOSE (41) This is sent to a desk accessory when the current application terminates, the screen is cleared and the window manager is reinitialized
 
msg[3] Identifier of the desk accessory

Note: This message plays practically no role in multitasking systems any more, and is also no longer present in MagiC!
 
AC_OPEN (40) A desk accessory has been activated
 
msg[4] Identifier of the desk accessory;
PC-GEM returns this information in msg[3]!, while KAOS 1.4.2 sets both entries

Geneva has the following extension:
If an application sends an AC_OPEN message to another application, it can optionally set WORD 4 of the message to -1; in this case, Geneva will automatically substitute the correct menu identifier for the application in WORD 4. Example to open application with ID #5:
 
int buf[8]im { AC_OPEN, 5, 0, my_apid, -1 };
appl_write( 5, 16, buf );
 
Sending an AC_OPEN message to a desk accessory will cause it to open if it is not already open, or it will make its window topmost (by sending a WM_TOPPED message) if the desk accessory has a window open; an application will receive a WM_TOPPED message, if it has a window open.
 
AP_DRAGDROP (63) This is a part of the Drag&Drop protocol and is sent by the sender to the receiver
 
msg[3] ID (handle) of the destination window
msg[4] X-position of the mouse pointer
msg[5] Y-position of the mouse pointer
msg[6] Keyboard Shift status
msg[7] 2-byte ASCII packed pipe identifier

Note: If a value of -1 is passed instead of a valid window ID, then the destination of the Drag&Drop operation is no specific window, but the application itself; in that case normally one should open an additional window for the specified data.
 
AP_RESCHG (57) With this message, which is a sub-command only found as a possible value in AP_TERM (50), the relevant application is informed that a resolution change is to take place; the receiver of this message should then terminate itself as soon as possible
 
AP_TERM (50) The operating system requests the application to terminate itself; this may be necessary for a resolution change, for instance, or triggered by a general Shutdown utility
 
msg[5] Reason for the shutdown, so e.g.
AP_TERM (General termination)
AP_RESCHG (Resolution change)

Warning: Contrary to the usual convention, the value -1 must be entered in msg[1], as according to MagiC documentation one can not guarantee otherwise that the desktop will react to an [Alternate]-[Control]-[Delete] Shutdown sequence
 
Note: Desk accesories will always be sent AC_CLOSE messages, not AP_TERM
 
AP_TFAIL (51) This is sent by the receiver of an AC_CLOSE or AP_TERM message if this does not wish to or cannot terminate itself
 
CH_EXIT (90) This is sent to the parent process when a child terminates
 
msg[3] Child's application ID
msg[4] Child's exit code
CT_KEY (53) This is sent by the modular control field XCONTROL to be able to evaluate key-presses that can have no effect on editable fields, such as [Help] or [Undo], for instance
 
msg[3] High byte: Scancode of the pressed key
Low byte : ASCII-code of the key
FNT_CHANGED (83) This is sent if GDOS fonts were loaded or unloaded at run-time.
At the receipt of this message the reaction should be vst_unload_fonts, followed directly by vst_load_fonts; this ensures that the application can work with the current fonts
 
MN_SELECTED (10) This is sent when a menu option is chosen
 
msg[3] The object index of the menu title selected
msg[4] The object index of the menu item selected
msg[5] Pointer to the OBJECT structure of the menu tree, as also passed in
msg[6] menu_bar
msg[7] Parent of the selected entry, i.e. the object index of the 'dropped down' box that contains the entry

Note: The presence of the extended message (msg[5] and following) is best inquired with appl_getinfo (opcode 9)
 
PRN_CHANGED (82) This message is sent by the GDOS configuration program to all reachable applications, to inform them about changes to device drivers; the following apply:
 
msg[3] Device number
msg[4] Action
0 = New
1 = Changed
2 = Removed

After receipt of this message, an application can re-open the corresponding workstation, for instance, obtain the current settings, and perhaps offer a new preview
 
RESCH_COMPLETED (61) This message is sent to the application that initiated a resolution change; if no error has arisen, this must now terminate itself
 
msg[3] Status (0 = error, 1 = OK)
SC_CHANGED (80) This message should be sent by a program to all other applications in the system when the contents of the GEM clipboard have been changed
 
msg[3] Description of the file format:
0x0000 = No more exact specification
0x0001 = Data for a database
0x0002 = Text files
0x0004 = Vector graphics
0x0008 = Raster graphics
0x0010 = Spreadsheet data
0x0020 = Samples, MIDI files, Sound
0x0040 = Archive files (e.g. ".zip", ".lzh")
0x8000 = System files (e.g. colour palettes)

If possible the format 0x0000 should be avoided!
msg[4] 4 characters that describe the "best" and format (least loss of information) for
msg[5] the data import; example ".RTF" rather than ".TXT"
msg[6] Reserved, 0
msg[7] Reserved, 0
SH_WDRAW (72) This message should be sent by an application to the system shell when the contents of a drive has been changed; following this the shell can update the corresponding window
 
msg[3] Drive (0 = A:, 1 = B:, etc)

Note: A value of -1 means that the shell should update all windows
 
SHUT_COMPLETED (60) This is sent by the operating system to the initiator of a Shutdown when all other applications have already been informed about this and have reacted positively
 
SM_M_SPECIAL (101) This message is only available under MagiC (as of Version 2.0), and must be sent to the screen-manager
 
msg[3] 0
msg[4] 'MA'
msg[5] 'GX'
msg[6] Desired action; the following apply:
0 = Perform a redraw
1 = Terminate an application
2 = Switch to an application
3 = Freeze an application
4 = Thaw out an application again
5 = No information known at present
6 = Unhide all applications
7 = Hide other applications
8 = Hide current application
msg[7] 0

Note: The codes 6..8 of msg[6] are available only as of MagiC Version 3.1. For "Perform a redraw" and "Unhide all applications" the ID to be passed must be that of the screen-manager (1).
 
THR_EXIT (88) This message is sent to the thread or the application that created the terminated thread; the following apply:
 
msg[3] AES ID of the terminated thread
msg[4] Return value or error-code as a
msg[5] LONG value
WM_ALLICONIFY (36) All windows of the application should be collected up in one iconified window
 
msg[4] X-coordinate, and
msg[5] Y-coordinate of top left of the iconified window
msg[6] Width, and
msg[7] Height of the iconified window
WM_ARROWED (24) This message is sent to an application to tell it that one of its slider widgets (arrow or scroll bar) was clicked on; the following apply:
 
msg[3] The handle (ID) of the window
msg[4] One of the following values:
WA_UPPAGE (0) = Page up
WA_DNPAGE (1) = Page down
WA_UPLINE (2) = Row up
WA_DNLINE (3) = Row down
WA_LFPAGE (4) = Page left
WA_RTPAGE (5) = Page right
WA_LFLINE (6) = Column left
WA_RTLINE (7) = Column right
WA_WHEEL  (8) = See below

As of XaAES v0.960 there is an extension of this message, since it has new drivers for a wheeled mouse:
 
msg[5] 'MW' (0x4d57) or 'Mw' (0x4d77)
'MW' (0x4d57) For the first mouse-wheel turn
'Mw' (0x4d77) For each further turn
 
msg[6] 0
 
msg[7] Current number of mouse-wheel turns; with this one can add together several turns, for instance for movement of the slider
 

But there is also the possibility of obtaining with WF_WHEEL real messages about mouse-wheel
 
msg[4] WA_WHEEL (8)
 
msg[6] Index of the wheel
 
msg[7] Number of mouse-wheel turns; with this one can add together several turns, for instance for movement of the slider
 

If WINX is installed one can get an extended WM_ARROWED message:
 
msg[5] Negates the speed factor for msg[4]
 
msg[6] Scroll type and direction, possible values as in msg[4]
 
msg[7] Negated speed factor for msg[6]
 

One should proceed as follows:
If [5] >=0, then we are dealing with a normal scroll message
If [5] < 0, then one negates the value and obtains the factor for [4]
If [7] < 0, then one negates the value and obtains the factor for [6]
Otherwise [6] will be ignored
 
Example:
If one receives [WM_ARROWED 1 0 win WA_DNLINE -2 WA_RTLINE -1] for instance, then one should scroll two lines downwards and one column to the right
 
WM_BACKDROPPED (31)
 
msg[3] Handle (ID) of the window in question

The application receives this message when operating the backdrop button of the window. This message is present only in KAOS 1.4.2 as well as MagiC 1 and 2; since MagiC Version 3, WM_BOTTOMED is sent.
 
WM_BOTTOMED (33) This is used by the screen-manager to request that the application should place a window in the background. In some TOS versions this is triggered by [Shift]-clicking on the window's mover bar; with MagiC (as of version 3) there is an extra widget for this (3rd from the right at the top).
 
msg[3] Handle (ID) of the window in question

Note: The window can then be simply placed by the application in the background with wind_set (msg[3], WF_BOTTOM, 0, 0 ,0, 0). Under MagiC 2.0 this message is still called WM_M_BDROPPED.
 
WM_CLOSED (22) This message is sent when the user clicks on a window's 'Closer' widget (top left corner), signalling that the topped window should be closed
 
msg[3] The handle (ID) of the window
WM_FULLED (23) This message is sent when the user clicks on the top window's 'Fuller' widget (top right corner)
 
msg[3] Handle (ID) of the window that is to be brought to its full size
WM_HSLID (25) This message is sent when the horizontal slider of the scroll bar has been moved
 
msg[3] Handle (ID) of the window
msg[4] The new slider position:
0000 = Far left
1000 = Far right
WM_ICONIFY (34) This message is sent when the user clicks on the 'Iconify' widget of a window (top, second rom the right), signifying that a window of the application is to be iconified
 
msg[3] Handle (ID) of the window in question
msg[4] X-coordinate, and
msg[5] Y-coordinate of top left of the iconified window
msg[6] Width, and
msg[7] Height of the iconified window
WM_M_BDROPPED (100) This is used by the screen-manager to request that the application should place a window in the background (say when the 'Backdrop' button is activated). As of MagiC 3 this opcode is no longer sent, but WM_BOTTOMED is used instead.
 
msg[3] Handle (ID) of the window in question
WM_MOVED (28) This message is sent when the user moves the whole window by dragging a window's title-bar
 
msg[3] Handle (ID) of the window
msg[4] New X-coordinate, and
msg[5] New Y-coordinate of top left of window
msg[6] New window width (unchanged)
msg[7] New window height (unchanged)
WM_NEWTOP (29) This message is sent when a window has been topped (brought to the front)
 
msg[3] Handle (ID) of the window
WM_ONTOP (31) This message is sent when a window (after closing or deactivating another window) becomes the top (current or active) one
 
msg[3] Handle (ID) of the window in question

Note: By the time the message arrives the window stack may have already changed again; the message is sent only when the application has not itself issued a call to place the window in the foreground
 
Messages of this type are coalesced in the AES message buffer. It follows from this that at all times the last message of this type will be received; thus there cannot be several of these messages in the buffer.
 
WM_REDRAW (20) This message warns an application that a part of the window area must be redrawn
 
msg[3] Handle (ID) of the window
msg[4] X-coordinate of the top left corner of the window area to redraw
msg[5] Y-coordinate of the top left corner of the window area to redraw
msg[6] Width of the portion of the window area to redraw
msg[7] Height of the portion of the window area to redraw
WM_SHADED (22360) This message is sent when a window has been 'shaded' (by double-clicking its title-bar so that only the title-bar remains visible
 
msg[3] Handle (ID) of the window
WM_SIZED (27) This message occurs when the user alters the window's size (by dragging the window's 'Sizer' widget at the bottom right corner)
 
msg[3] Handle (ID) of the window
msg[4] New X-coordinate, and
msg[5] New Y-coordinate of the window's top left corner (both unchanged)
msg[6] New window width
msg[7] New window height
WM_TOOLBAR (37) This message is sent when a toolbar object is clicked on; the following apply:
 
msg[3] Handle (ID) of the window
msg[4] Object clicked on
msg[5] Number of mouse clicks
msg[6] Keyboard state of [Shift], [Alternate] and [Control]

Note: All objects of the toolbox should have the TOUCHEXIT flag set. This does not apply for XaAES, for which there is an additional value:
 
msg[7] Current object in which the text cursor is positioned
 
WM_TOPPED (21) This message is sent when an application window which is not currently topped is clicked on by the user to move it to the top (made active)
 
msg[3] The handle (ID) of the window
WM_UNICONIFY (35) This message is sent when the user double-clicks one or more iconified windows of an application to uniconify it/them; if several windows are affected (WM_ALLICONIFY) then it is up to the application alone to process this, as the AES does not make available any information about the windows in question, including their positions or dimensions
 
msg[3] Handle (ID) of the window in question
msg[4] X-coordinate, and
msg[5] Y-coordinate of top left corner of the uniconified window
msg[6] Width, and
msg[7] Height of the uniconified window
WM_UNSHADED (22361) This message is sent when a window has been 'unshaded' (by again double-clicking its title-line) to make the whole window visible
 
msg[3] Handle (ID) of the window
WM_UNTOPPED (30) This message is sent when the current window has been sent behind one or more windows due to another window becoming the active one
 
msg[3] Handle (ID) of the window in question

Note: By the time the message arrives the window stack may have already changed again; the message is sent only when the application has not itself issued a call to place the window in the background
 
WM_VSLID (26) This message indicates that the vertical slider of the scroll bar has been moved
 
msg[3] Handle (ID) of the window
msg[4] The new slider position:
0000 = At the very top
1000 = At the very bottom

Support of the newer message types can be inquired with appl_getinfo (opcode 12). Incidentally, for user-defined messages Digital Research has suggested message numbers beyond 1024.

About the size of the message buffer:

An individual application should not use more than 16 windows under MagiC 2.0, as otherwise the message buffer of the system can overflow and possibly redraws can no longer be performed.

8.7.9.1 The CAB protocol

The CAB protocol consists of a series of AES messages with whose aid any GEM programs can devolve certain tasks to CAB, or coordinate certain actions with CAB.

The contents of the environmental variable BROWSER= (if defined) holds CAB's access path. If CAB is not already in memory, then a program can launch CAB subsequently via this variable.

A possible application: If one offers further current information or updates for one's own programs on the internet, one could use the CAB protocol to provide access to this information from within these programs with little effort. CAB then takes care of the download of the data and its presentation.

Description of the messages

CAB_HELLO (0xCAB8) (message from CAB)
CAB transmits after its launch the following message to all running programs:

msg[0] = 0xCAB8
msg[1] = Id von CAB
msg[2] = 0
msg[3] = Version of the CAB protocol (0x0100 corresponds to V1.00)
msg[4] = Bit-vector with the internet protocols supported by CAB
         (CAB.OVL):
             Bit 0: HTTP
             Bit 1: FTP
             Bit 2: GOPHER
             Bit 3: WAIS
             Bit 4: MAILTO
             Bit 5: NNTP
             Bit 6: TELNET
             Bit 7-15: 0 (reserved)
msg[5] = Bit-vector with the CAB protocol messages supported by CAB:
             Bit 0: CAB_VIEW
             Bit 1: CAB_MAIL, CAB_MAILSENT
             Bit 2: CAB_REQUESTSTATUS, CAB_RELEASESTATUS, CAB_STATUS,
                    CAB_EXIT
             Bit 3-15: 0 (reserved)
msg[6] = 0
msg[7] = 0

CAB_SUPPORT (0xCABB) (message to CAB)
If this message is sent to CAB, then CAB sends back the message CAB_HELLO. If CAB_HELLO is not returned, then an old version of CAB is being used that does not yet support the CAB protocol. All programs that are interested in the information that CAB_HELLO delivers should send CAB_SUPPORT to CAB after their launch. If CAB is only launched later, then CAB_HELLO is sent automatically to the program.

msg[0] = 0xCABB
msg[1] = Id des PRGs
msg[2] = 0
msg[3] = 0
msg[4] = 0
msg[5] = 0
msg[6] = 0
msg[7] = 0

CAB_VIEW (0xCAB3) (message to CAB)
Similar to VA_START, but instead of a fielname a URL is passed. CAB then displays this file.

msg[0] = 0xCAB3
msg[1] = ID of the PRG
msg[2] = 0
msg[3] = \ Pointer to the URL
msg[4] = /
msg[5] = If a 1 was entered here CAB displays the URL in a new window;
         if a 0 was entered, the top CAB window will be used
msg[6] = 0
msg[7] = 0

CAB_REQUESTSTATUS (0xCAB5) (message to CAB)
This can be sent to CAB to check whether CAB is currently online or offline. CAB subsequently sends the message CAB_STATUS at each change of the online/offline state.

msg[0] = 0xCAB5
msg[1] = ID of the PRG
msg[2] = 0
msg[3] = 0
msg[4] = 0
msg[5] = 0
msg[6] = 0
msg[7] = 0

CAB_RELEASESTATUS (0xCAB7) (message to CAB)
This should be sent to CAB when a program is no longer interested in the on/offline information that was requested with CAB_REQUESTSTATUS (e.g. because it terminates itself).

msg[0] = 0xCAB7
msg[1] = ID of the PRG
msg[2] = 0
msg[3] = 0
msg[4] = 0
msg[5] = 0
msg[6] = 0
msg[7] = 0

CAB_STATUS (0xCAB6) (message from CAB)
This is sent by CAB to all programs that have registered themselves with CAB_REQUESTSTATUS.

msg[0] = 0xCAB6
msg[1] = ID of the PRG
msg[2] = 0
msg[3] = 1 if CAB online; 0 if CAB offline
msg[4] = 0
msg[5] = 0
msg[6] = 0
msg[7] = 0

CAB_EXIT (0xCAB1) (message from CAB)
This is sent by CAB as soon as CAB terminates to all programs that have registered themselves with CAB_REQUESTSTATUS. Before this a CAB_STATUS is sent in which the offline state is reported.

msg[0] = 0xCAB1
msg[1] = ID of the PRG
msg[2] = 0
msg[3] = 0
msg[4] = 0
msg[5] = 0
msg[6] = 0
msg[7] = 0

CAB_MAIL (0xCAB9) (message to CAB)
This can be sent to CAB to transmit mails.

msg[0] = 0xCAB9
msg[1] = ID of the PRG
msg[2] = 0

msg[3] = \ Pointer to the URL; a subject can be appended directly to
msg[4] = / the URL, separated by a question mark

msg[5] = \ Pointer to a file holding the mail contents, or NULL (in
msg[6] = / which case CAB opens an editor into which the mail can be
           entered)

msg[7] = Bit-vector with further options:
             Bit 0: 0 if the mail file is to be sent immediately, or 1
                    if the mail file is still to be edited/altered in
                    CAB by the user
             Bit 1: With 1 the mail file will be deleted after it has
                    been sent, while 0 means it will be retained
             Bit 2-15: 0 (reserved)

CAB_MAILSENT (0xCABA) (message from CAB)
This is sent by CAB to the program that has sent CAB_MAIL and contains infomation whether sending of the mail worked correctly or not.

msg[0] = 0xCABA
msg[1] = ID of CAB
msg[2] = 0
msg[3] = 1 if the mail was sent without error; 0 if an error occurred
         (in which case one can find the cause of the error in msg[4])
msg[4] = Contains an error number if msg[3]=0
              0: No URL specified
              1: Offline, net connection failed, server not accessible
              2: User has aborted the action (if the mail is to be
                 modified in CAB, the user has the option of aborting
                 the action)
              3: GEMDOS error on accessing the mail file
              4: Editor for modifying the file could not be called
msg[5] = 0
msg[6] = 0
msg[7] = 0

8.7.9.2 Messages from Geneva

X_MN_SELECTED (0xE000)


This message is either accompanied by the MU_MESAG bit of an evnt_multi return, or is returned by the evnt_mesag call. When this message occurs, the message buffer contains:
 

Portion Contents
msg[0] 0xE000
msg[3] The object index of the menu title selected
msg[4] The object index of the selected menu item
msg[5], [6] The object tree of the menu item selected
msg[7] The handle of the window containing the menu

This feature is used in conjunction with the wind_set option X_WF_MENU, described in detail, below.
 

X_WM_SELECTED (0xE100)


This message is received when the user clicks on a window gadget in a window whose flags were modified with the wind_tree function. It only occurs when the X_WTFL_CLICKS attribute is off. If the user clicks on one of the normal scroll gadgets or arrows, a standard WM_ARROWED message is sent to the application. However, when the user clicks on any other gadget, an X_WM_SELECTED message is sent:
 

Portion Contents
msg[0] 0xE100
msg[3] The handle of the window containing the gadget
msg[4] The object index of the window tree object the user
  clicked on

This feature is used by the Task Manager's "Keyboard..." dialog.
 

X_GET_HELP (0xE200)


This message is sent to the Help display program when the user requests help on a certain topic. The message is actually comprised of two parts. When the application sees the X_GET_HELP message, it must then use the appl_read function to get the entire remainder of the message, whether it intends to use the whole thing or not. The first part of the message is comprised of the following values:
 

Portion Contents
msg[0] 0xE200
msg[1] Application ID
msg[2] Length of the second part ofthe message
msg[3] Length of the topic portion of the message, including
  the NUL terminator
msg[4] Length of the filename portion of the message, including
  the NUL terminator
msg[5] Upper/lowercase sensitivity. If non-zero, the topic is
  case-sensitive.

The second part of the message contains the actual text of the topic and filename fields. This can be read with one or more calls to appl_read.
 
Example:
 
    void read_string( char *s, int max, int size )
    {
      char dummy;

      if( size<=max )               /* the whole string fits */
        appl_read( my_application_id, size, s );
      else
      {
        /* read what we can */
        appl_read( my_application_id, max-1, s);
        s[max-1] = '\0';            /* terminate the string   */
        /* now, get the remaining bytes of the string         */
        for( size=size-(max-1); size>0; size-- )
           appl_read( my_application_id, 1, &dummy );
      }
    }

    main()
    {
      int msg[8], caps_sens;
      char topic[20], filename[100];

      evnt_mesag( msg );
      switch( msg[0] )
      {
        case X_GET_HELP:
           caps_sens = msg[5];
          /* Read the topic portion */
           read_string( topic, sizeof(topic), msg[3] );
          /* Read the filename portion */
            read_string( filename, sizeof(filename). msg[4] );
          /* Do whatever with it... */

X_WM_HSPLIT (0xE400)


This message is sent to an application when the position of the horizontal split bar has changed:
 

Portion Contents
msg[0] 0xE400
msg[1] Application ID
msg[2] 0
msg[3] Handle of the window being affected
msg[4] The new offset (in pixels) of the split bar

The application is then free to either act upon this message and change the split bar position with wind_set(X_WF_HSPLIT), or to ignore the message completely.
 
See the x_wind_create function for more information.
 

X_WM_ARROWED2 (0xE600)


This message is sent to an application when the user has licked on one of the arrow or scroll bar gadgets which are not reported by the normal WM_ARROWED message. X_WM_ARROWED2 reports changes in gadgets which are below a vertical split bar and/or to the right of a horizontal split bar. The format of a X_WM_ARROWED2 message is identical to that of WM_ARROWED.
 
See the x_wind_create function for more information.
 

X_WM_HSLID2 (0xE700)


This message is sent to an application when the user has dragged the second horizontal scroll gadget, which appears to the right of a horizontal split bar. The format of this message is identical to that of WM_HSLID.
 
See the x_wind_create function for more information.
 

X_WM_VSLID2 (0xE800)


This message is sent to an application when the user has dragged the second vertical scroll gadget, which appears below a vertical split bar. The format of this message is identical to that of WM_VSLID.
 
See the x_wind_create function for more information.
 

X_WM_OBJECT (0xE900) (since Release 003)


This message type is returned to an application when it uses wind_set mode X_WF_OBJHAND to affect the manner in which window gadgets are handled.
 
If an application receives this message, it is because the object tree handler routine instructed Geneva not to process the mouse click on a window gadget as a normal event. Instead, a special message is returned to the application:
 

Portion Contents
msg[0] 0xE900
msg[1] Application ID
msg[2] 0
msg[3] Handle of the window containing the object
msg[4] Object tree index of the object which was clicked

Note that in order for Geneva to determine that the mouse has been clicked on an object in a window's tree structure, it must be of type EXIT or TOUCHEXIT. Geneva's default window gadgets already have these attributes set correctly.
 
See also: wind_set mode   X_WF_OBJHAND.
 

8.7.9.3 RSDAEMON_MSG

The RSDAEMON is a parallel-running application which assumes the task of the resolver with an AES message. It's intended as a kind of non-blocking gethostbyname, although the RSDAEMON only returns an IP, not a complete hostent-struct.

The RSDAEMON is normally started and terminated automatically by IConnect.

Utilization:

With appl_find("RSDAEMON") the App ID is to be obtained. In case of error one should fall back to the blocking gethostbyname, and only if nothing else is possible, break off with an error-message.

Now the RSDAEMON can be sent an AES message:

#include <rsdaemon.h>

pbuf[0]=RSDAEMON_MSG
pbuf[1]=<eigene App-ID>
pbuf[2]=0
pbuf[3]=RSD_REQUEST_IP
pbuf[4]=<Own freely choosable ID, to be able to assign the reply>
pbuf[5/6]=<Pointer to the string that contains the nname of the host>
           (Pay attention to possible memory protection!)

The RSDAEMON returns a reply of the following form:

pbuf[0]=RSDAEMON_MSG
pbuf[1]=<RSDAEMON ID>
pbuf[2]=0

pbuf[3]=RSD_IP_UNKNOWN = IP could not be obtained. This may be due to
                         various causes (user has not entered a DNS,
                         the DNS does not recognize the host etc.)
pbuf[4]=<Here the ID of the request is returned>

or:

pbuf[3]=RSD_IP_FOUND
pbuf[4]=<Here the ID of the request is returned>
pbuf[5/6]=<IP of the host as ulong>

And here still the RSDAEMON.H:

#ifndef __RSDAEMON__
#define __RSDAEMON__

#define RSDAEMON_MSG    0x995

#define RSD_REQUEST_IP  1
#define RSD_IP_FOUND    2
#define RSD_IP_UNKNOWN  3

#endif
