How can I specify a minimum window size for a FXTopWindow (or one of its subclasses, like FXMainWindow or FXDialogBox)?
FXTopWindow has two hints you may use: DECOR_STRETCHABLE and DECOR_SHRINKABLE. Instead of DECOR_RESIZE, specify either one of them to control the resizing of the window. The FXDragCorner doesn’t seem to notice these two hints and window managers may not follow these hints .So if your window is supposed to stay fixed size, don’t stick a FXDragCorner in the window!!!
