_SETwindowTransparency

_SETwindowTransparency

Set the transparency values of a window.
The transparency can be processed with a transparency color or with an alpha blending factor.

You must add the WN_TRANSPARENCY flag to the window creation (_CRwindow) in order to process the window transparency.
If an ObjContainer is added to the window, please use _SETcontainerTransparency instead.

Important

Windows 95/98/ME are not able to internaly process the window transparency, so the transparency has to be simulated.
2000/XP programers can use _SIMULATEwindowTransparency (or _SIMULATEcontainerTransparency) in order to get an idea of the transparent items behaviour, running with 95/98/ME.
