Thank's for the pointers. It seems to me that they access it via 'self theme'; in any case my problem is, for the moment, solved.

Thanks,
Peter

Hi,

how is set the background color of a morph?

A morph has the fillStyle/color attribute, but this does not mean it uses this color for its drawing method.
(for example ActiveHand color -> Color blue, and the hand/cursor is not blue).

I could access directly "Smalltalk ui theme backgroundColor" from within the Morph,

this returns always the same color, it is actually the desktop backgroundcolor.

but I don't see anywhere that something is using themed colors this way.
So I assume there is some other way; what am I missing?

Note that I don't want to use the color for background of the morph but I need to make a decision based on the color in the morph.

It depends on the morph, or the type of widget this morph represents.
A button has a theme dependent color, that may depend on the type and state (enabled/disabled) of the button.
A list morph may have different colors for even and odd index, selected, enabled, disabled ...
A label model font/color may depend on its use (window title/menu title/ button label ...).

Look at the xxxFillStyleFor: messages in UITheme

Thanks,
