What is the best way to "select" and area of the screen (row) then for pre-4.x OS? I could not find a Glue function for this. How does the OS select an area? TIA, - Dan :D

I don't see that this is supported for scrolling operations before 4.0 (even if the x/y deltas are zero). That is, I don't see it supported in 3.3 or 3.5. However, 3.5 has the benefit of actually telling you that it's not supported. -- Keith At 6:37 PM -0600 4/25/02, Dan Dorton wrote: >I am using the WinCopyRectangle() function with the winPaintInverse >transfer mode: > >WinCopyRectangle(NULL, NULL, bounds, bounds->topLeft.x, >bounds->topLeft.y, winPaintInverse); > >I have no problems when running on OS 4.x, but when I try on any 3.5 >version of the OS, I get the following error: > >Appname (ver) called SysFatalAlert with the message "Bliter.c, >Line:3338, Unsupported transfer mode." > >If I try on OS ver 3.3, I get no errors, the area just does not invert. > >The documentation states: > >"In OS versions before 3.5, the mode parameter was defined as type >ScrOperation.
