I've found a suspect.
SetParent triggers the handle creation
TSynEdt.CreateWnd calls SizeOrFontChanged that calls UpdateScrollBars
Here, since PaintLock <> 0 the scrollbar change is postponed
Martin/Bart, can you check if you pass the check for PaintLock in
UpdateScrollBars?
Alternatively comment the call to SizeOrFontChanged in CreateWnd and
see what happens
More info:
SynEdit.CreateHandle -> DoDecPaintLock -> UpdateScrollBars ->
ShowScrollBar (LCL) -> ShowScrollBar (Win32) -> Windows.RedrawWindow
I don't think it can be avoided.
I can detect the situation of course, but preventing that call, might lead
to wrong display results.
OK.
What OS are you using.
Here with windows 7 no Paint occurs at all. See previous mail
Can you check (comment ShowScrollBar) if the paint you are seeing is
really from ShowScrollBar?
This would not make sense?
Nothing, except the scrollbars is painted (SynEdit does not paint). If I
do not call ShowScrollbar, then there are no scrollbars that could be
painted.
