From MagiC 3 onwards a 3D-look is available for objects, which however differs in some details from the Atari variant. The most important points is summary:
The 3D-look is only available in resolutions with at least
While in TOS 4.0 one can use objc_sysvar to influence the
behaviour of indicators and activators as well as colours, MagiC
permits only interrogation of the data. For the colours, MagiC always
uses colour numbers 8 and 9 (light or dark grey).
Activators are always shown as depressed for SELECTED, while
indicators or background objects are colourized
Indicators and background objects are treated in the same way
3D effects can be applied to all object types, which includes
text input fields, headings, group frames etc.
3D objects do not get an additional border and hence do not
alter their size. Depending on the border width they stand out better,
and in some circumstances may also have an additional border and
shadow. The headings should have a height of 1+3 instead of the
previous 1+2, so that everything looks tidy.
The object status DRAW3D is ignored
Ornamental borders for dialog boxes will be created only if an
inner border of 2 pixels and OUTLINED was selected
