I'm trying to figure out some issues with monitor hotplugging in Xquartz, and I think I've narrowed it down to the way we try to resize the root window and I was hoping to get some feedback on what would be "the right way" do do this. We try changing the dimensions of the root window via: pRoot = WindowTable[pScreen->myNum]; pScreen->ResizeWindow(pRoot, x - sx, y - sy, width, height, NULL); I've spewed out some debugging that shows the following: Calling: RootlessResizeWindow(pRoot, 0, 0, 1440, 1860, NULL) pRoot->drawable now: 2720, 960 pRoot->clipList.extents now: 2720, 960 pRoot->borderClip.extents now: 2720, 960 pRoot->winSize.extents now: 2720, 960 pRoot->borderSize.extents now: 2720, 960 pScreen->ResizeWindow is RootlessResizeWindow which essentially just does miSlideAndSizeWindow via: HUGE_ROOT(pWin); SCREEN_UNWRAP(pScreen, ResizeWindow); pScreen->ResizeWindow(pWin, x, y, w, h, pSib); SCREEN_WRAP(pScreen, ResizeWindow); NORMAL_ROOT(pWin); Breakpoint 1, RootlessResizeWindow (pWin=0x581370, x=0, y=0, w=1440, h=1860, pSib=0x0) at rootlessWindow.c:1369 (gdb) print pScreen->ResizeWindow $1 = (ResizeWindowProcPtr) 0x4f85f <miSlideAndSizeWindow> And in miSlideAndSizeWindow, we have: /* if this is a root window, can't be resized */ if (!(pParent = pWin->parent)) return ; So it looks like this is intentional. So... how should I be resizing the root window? Thanks in advance, Jeremy
