I thought about reparent xwindow into NSWindow, but as you said, it is a waste of memory. The only gain is to use GNUstep drawing/font/localization facility. > > My current solution/code is to split the WM library into layers. > 1st, non-X layer for generic windowing. 2nd, Xlib/XCB layer that need no > AppKit and 3rd, AppKit layer which will use many > NSWindows to do decoration so that you don't need to waste the > memory in the middle area of each window.

My approach is trying to decompose a regular window manager into several small components, like taskbar, pager, etc. Most of them can be GNUstep applications. They all listen to the root window in XWindow system. The real window manager is only responsible for window mapping and decoration. Although I don't know how far I can go, but if it can work out, the real window manager can be small, may not depending on GNUstep NSWindow, but easier to maintain.

Well, I would say it is not in the near future. :D Yen-Ju > > _______________________________________________ > Etoile-discuss mailing list > [email protected] > https://mail.gna.org/listinfo/etoile-discuss > > > _______________________________________________ Etoile-discuss mailing list [email protected] https://mail.gna.org/listinfo/etoile-discuss
