Yes, i prefer version 1.3.x. I am in accord with you (groups is the best option), but the reason of why to use sub-windows inside a group, if because my app uses: An movable child-window (with buttons inside), that floats over a scrollable background in the main window. When using pure groups(with no subwindows), when the movable window is over scrollable area, and the scrolls are moved up or down, part of movable window is scrolled too, and distorts the widgets. Using one sub-Window inside one sub-Group corrects this behavior, and the widgets don't distort and looks ok. Anyway, my question is: Why, If i build the widget group (containing the sub-window) at compile time, it works okay. But if i build the same widget at run-time (callbacks), the sub-window only is shown if the main window is hidden and re-shown using the window manager. My sent program demonstrates this, but how to fix this..? Thank you for your valuable answer.
