I'm trying to make a temporary popup window appear in
the center of the display. I discovered that the
WinDraw... functions draw relative to the upper left
corner of the active window (doh.. imagine that!). Then
I discovered WinWindowToDisplayPt, that converts window-
relative coordinates to display-relative. That works
great, except that what I draw is clipped by the border
of the display window (causes problems when the find
dialog is open, or a category popup list is open). So, I
tried temporarily changing the clipping window (using
WinGetClip and WinSetClip) to match the rectangle I'm
trying to draw, using the display relative coordinates I
got back from WinWindowToDisplayPt. Apparently the
clipping rectangle is intersected with the draw window's
boundaries.
Having met with failure trying to draw upon whatever
window happens to be the draw window, I then tried a new
approach: creating a new window, using WinCreateWindow,
WinEnableWindow, WinSetDrawWindow, etc. However, nothing
appears on the display.
Does anybody have any sample code they wouldn't mind
sharing? I've searched the knowledge base in vain.
Thanks.
