Summary0002942: JvCustomItemViewer doesn't draw scroll bars correctly with xp theme enabled
DescriptionThe WMNCPaint method in JvCustomItemViewer.pas is

procedure TJvCustomItemViewer.WMNCPaint(var Messages: TWMNCPaint);
begin
  {$IFDEF JVCLThemesEnabled}
  if ThemeServices.ThemesEnabled then
    ThemeServices.PaintBorder(TWinControl(Self), False)
  else
  {$ENDIF JVCLThemesEnabled}
    inherited;
end;

While theme is enabled, it handles WM_NCPAINT message, so that windows can not respond to this message and update scroll bars.

I think the code should be change to:

procedure TJvCustomItemViewer.WMNCPaint(var Messages: TWMNCPaint);
begin
  inherited;
  {$IFDEF JVCLThemesEnabled}
  if ThemeServices.ThemesEnabled then
    ThemeServices.PaintBorder(TWinControl(Self), False);
  {$ENDIF JVCLThemesEnabled}
end;
TagsNo tags attached.
