[linux-audio-dev] Re: Project: modular synth editor

[ gnomecanvas ] [ Posted this to gtk-app-devel-list as well. Reply to where you wish as I will summary. ] Should the module widgets be put to a fixed size container before they are inserted to the canvas? Or what is the problem? I tested with Glade: created a top window with one "Fixed Position" container widget, added viewport to the "Fixed Position", inserted vbox to viewport, inserted horizontal scales to each slot of the vbox. Then I took the properties of the viewport and changed viewport's position and size. Only problem appeared when the viewport size was made smaller than the minimum size of all scales. Viewport could be made very small in which case the scales were clipped agains the viewport. Is there any way to determine when the viewport becomes smaller than the vbox holding the scales? (Or the vbox larger than the viewport.) Does the viewport generate any signals in these cases? Is the viewport a wrong widget for the task? Is there any other constant size container in GTK?
