If not I'll take a look how to do the job with TFontCache and friends. Once the glyphs are in a TImageList they can be selected in many MSEgui widgets. TFace and TFrame also have the possibility to show pixmaps so actually every TWidget can show an icon. [...] > Thanks for links. Very helpful. I need to study it first.

Another option is to use a 'TScrollBox' and to arrange the children in TScrollBox.OnLayoutChanged.
