There is no use if that gets that complex, that nobody implements it ;-)
While that's certainly true, I fear the nature of the matter includes some complexity. There's no point in providing a protocol that requires huristics on either side to "work as expected" either :-( One cannot do this with the idea of an "interim solution until gtk+ stops this nonsense" - as, even in that case, the spec would still remain. If CSD is to be included into NETWM, it shall be done proper. This was and is my biggest complaint on the rather hackish gtk+ approach - now I cannot drop behind that, sorry ;-) Notes on the last version: -------------- * why does _NET_WM_TITLEBAR_ACTION require root_x/root_y? we cannot map it to anything special inside the titlebar anyway. * "Button takes the special value of 0 which indicates a LEFT BUTTON double click on the title bar area.", but we can now probably use one of the position fields as flag (also to pass the modifiers, ie. alt, ctrl, meta)? * The other field could be used to specify the deco element (button), eg. at least KWin maximize acts differently for different buttons - the CSD could defer handling the button to the WM to keep this consistent among all clients. For _NET_WM_SHOW_WINDOW_MENU * root_x/root_y should really specify explicitly invalid values that are not treated as position request * I support Carstens point about sending a rect to align the menu to. This will be required if the menu cannot be spawned below the button - something the client cannot know. (The menu must not cover the button that triggered it) I don't think we'll require an anchor for the rect, but can seek to spawn the dialog preferably inside the clients geometry (ie. if the target rect is on the top left of the client, the popup shall be bottom left aligned - it's never "next to" the titlebar, since the entire point of CSD is that there is no titlebar) Unfortunately this may require x/width to cover the first 16 and y/height the last 16 bits of data.l[1|2] | root_x, root_y, width, height > 0 data.l[1] = (root_x << 16) | (root_y & 0xffff) data.l[2] = (width << 16) | (height & 0xffff) root_x = (data.l[1] >> 16) & 0xffff; root_y = data.l[1] & 0xffff; width = (data.l[2] >> 16) & 0xffff; height = data.l[2] & 0xffff; Cheers, Thomas _______________________________________________ wm-spec-list mailing list wm-spec-list@gnome.org https://mail.gnome.org/mailman/listinfo/wm-spec-list
