Thanks. I did some more googling and managed to rework a fullscreen operation into a maximise operation. I haven't done any Xlib programming (outside of FLTK's Fl_x.cxx) before, so I may be wrong. Here's the X code that I've tested. It properly maximises the Fl_Window so that the maximise/restore icon on the border is set to "restore". Note that 'wnd' is the Fl_Window. ---8<------ Window xid = fl_xid(wnd); XEvent xev; Atom wm_state = XInternAtom(fl_display, "_NET_WM_STATE", False); Atom vmax = XInternAtom(fl_display, "_NET_WM_STATE_MAXIMIZED_VERT", False); Atom hmax = XInternAtom(fl_display, "_NET_WM_STATE_MAXIMIZED_HORZ", False); memset(&xev, 0, sizeof(xev)); xev.type = ClientMessage; xev.xclient.window = xid; xev.xclient.message_type = wm_state; xev.xclient.format = 32; xev.xclient.data.l[0] = 2; xev.xclient.data.l[1] = hmax; xev.xclient.data.l[2] = vmax; XSendEvent(fl_display, DefaultRootWindow(fl_display), False, SubstructureNotifyMask, &xev); --->8------ I just need to figure out how to determine if the window is already maximised :) Oh, and how to "restore" the window as well. -- Alvin _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
