Start with a normalized window, then maximize horizontally, e.g.: ================================================ wmctrl -i -r '<window ID>' -b add,maximized_horz ================================================ This works. Then issue the maximized_vert command: ================================================ wmctrl -i -r '<window ID>' -b add,maximized_vert ================================================ Nothing happens. If you start off with a successful vertical maximization command, then the horizontal one fails (but of course doesn't tell wmctrl...). It looks like the code is hardcoded to treat either MAXIMIZED_HORZ or MAXIMIZED_VERT as 'maximized' (client.h:157): ========================================================================= #define CLIENT_FLAG_MAXIMIZED (CLIENT_FLAG_MAXIMIZED_VERT | \ CLIENT_FLAG_MAXIMIZED_HORIZ) ========================================================================= so when the command to add the maximized state is processed in netwm.c:clientUpdateNetState, line 381, the code ignores valid maximization commands in the axis that hasn't been maximized: ========================================================================= if ((action == NET_WM_STATE_ADD) && !FLAG_TEST (c->flags, CLIENT_FLAG_MAXIMIZED)) { mode = 0L; if ((first == display_info->atoms[NET_WM_STATE_MAXIMIZED_HORZ]) || (second == display_info->atoms[NET_WM_STATE_MAXIMIZED_HORZ])) { mode |= !FLAG_TEST (c->flags, CLIENT_FLAG_MAXIMIZED_HORIZ) ? CLIENT_FLAG_MAXIMIZED_HORIZ : 0; } <etc> ========================================================================= is there a reason maximization in one axis only isn't being considered? Feels deliberate. Thanks
As this has been ignored, I have looked into fixing it - turns out there is already a proper test that can be applied here - FLAG_TEST should be swapped with FLAG_TEST_ALL, since a window is only truly maximized when both axes are maximized: =============================================================================== if ((action == NET_WM_STATE_ADD) && !FLAG_TEST_ALL (c->flags, CLIENT_FLAG_MAXIMIZED)) =============================================================================== This way just being maximized in one axis doesn't prevent the other from being applied.
