Hi,
Thanks for you quick reply... I've played with VirtualDevice for a few
days now...
I assume what you suggest is:
SmGraphicWindow::Paint(const Rectangle&)
{
size = ...
VirtualDevice vDev(*this, 0, 0);
vDev.SetOutputSize(size);
rDoc.Draw(vDev, aPoint); //The drawing code...
DrawOutDev(Point(0,0), size, Point(0,0), size, vDev);
}
I've tried this... But it doesn't solve the flickering, and it somehow
disables anti-alias... I've also tried to do the actual drawing on
vDev in PrePaint (not a great place I know, but might work),
nevertheless this didn't solve the issue either...
You can enable antialiasing with SetAntialias (call and flags in
vcl/outdev.hxx).
I guess the problem is the Erase() call in Window::ImplCallPaint()...
Anyway, this issue isn't important (yet), so I'll work on something
that is. And post back here if I get back to playing with this issue
again...
Good point. If you draw fully opaque, you can disable the Erase by
setting no background at all calling SetBackground() (the method without
wallpaper).
Just my 2 cents, pl
