AFAIK with TCustomControl you obtain just Resize and then Paint. Paint is preceded by WMPaint. You should move your code to one of these methods. Vojtěch a.k.a. Blaazen ______________________________________________________________

In a large project I found out that after on resizing of the form, some components get properly resized but don't receive an Invalidate call. I guess, it's caused by the test in lcl/include/control.inc if not ((csLoading in ComponentState) or (Self is TWinControl)) then InvalidateControl(IsControlVisible, False, true);Our component extends TCustomControl, so it doesn't get invalidated. I guess, such components are supposed to use a different mechanism, but I can't see how? Can someone point me to the right doc. ---------- -- _______________________________________________ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus <https://lists.lazarus-ide.org/listinfo/lazarus>
