Hi Thomas.. Hiding windows is as simple as window->SetOpacity( window, 0 ); The SaWMan call is likely to allow a windowmanager to act upon changing a window's visibility, not sure cause it's not implemented as you point out. SetOpacity results in update_region() which will do a SAWMAN_VISIBLE_WINDOW( window ) check.
ISaWMan and ISaWManager constitute of callbacks issued by SaWMan. Of course, inside these callbacks, you may need to query/change some SaWMan status; for that you'll use the calls in sawman_manager.h. For instance, you might want to prevent a certain window getting focus. In the required callback (which is generally issued before SaWMan performs the change) you can override the behaviour, or if it's not this certain window, follow the default behaviour by calling the 'official' change focus func. hth, Niels Thomas Gutteridge wrote: > Hello > > I have a couple of questions about SaWMan: > > Firstly, I notice that the function SetVisible() in the ISaWManManager > interface is not implemented.
