Hello; here's a weird one:
Normally, a dialog is at least as big as the sum of its content according to the layout. It does not matter which layout flags you use (FIT, SCALE, SIZE) - it will not get any smaller, even when embedding the dialog into a screen Layout or moving the dialog's borders.
You can use a SCROLLGROUP to include a subarea that is larger than the dialog itself, yes. But what if I just don't want "overhanging" items to show? No scrollbar, no enforced size, just clipping. I know it is possible because the toolbars behave like this; icons outside of the current toolbar just disappear when the toolbar is resized too much.
Apparently that doesn't work with an external layout file?
