Hi,
this is generally not possible. You can only draw within your window
bounds. However there is a method to draw also in the region that is
occluded by the child windows of a window (thereby painting on those
child windows, too). This can be done using the
Window::SetParentClipMode( PARENTCLIPMODE_NOCLIP ) method.
The normal ruler however does not do that AFAIK; it seems it simply
draws to the correct window. For details see the SvxRuler class:
svx/source/dialog/svxruler.cxx in the method SvxRuler::DrawLine_Impl.
Just my 2 cents, pl

Hello!
Can I draw some parts of GUI element outside it (its window)? For
example, how can ruler draw over document field? Is it possible?
Thanks.
