I use the TScrWnd class to show umbrellas of the beach into a oPanel and this oPanel is created on a dialog ( Tfsdi) a special dialog with ::nStyle := nOR( WS_CHILD, 4 )
Now when I use the Vertical or the Horizontal scrollBar it not refresh the controls there are into this oPanel as you can see in this picture :
Only when I change the size of Splitter it refresh the oPanel
What I can addd to say when the final user use the scrollbars it must refresh the oPanel ? Any Idea please ?
