** Description changed: gtk 2.22, Ubuntu 10.10 1. Click on the volume control to open the sound menu. 2. Move the pointer diagonally to click on the maximum volume button. + <https://launchpadlibrarian.net/42732636/Why_autoexpanding_indicators_are_a_bad_idea.png> What often happens: The sound menu closes, and the menu next to it opens. - Screnshot: https://launchpadlibrarian.net/42732636/Why_autoexpanding_indicators_are_a_bad_idea.png Screencast: <https://www.youtube.com/watch?v=lVUokjAlREs> Example in an informal usability test: <https://www.youtube.com/watch?feature=player_detailpage&v=PgGbZfR6Vec#t=13m55s> What should happen: The sound menu stays open. - A solution would be to use a timer for the 'auto-expanding' feature. + One solution would be to make the volume slider vertical. But this would + not work for other menus (like the Bluetooth menu), and would look + awkward with other items in the menu. - From an IRC conversation on this bug: - "<bratsche> Okay, so gtk+ has something internal called (I think) a stay-up triangle.. but as far as I know, it's only used when dealing with submenus from a menu. - But try to envision a menu with several menuitems, and the first menuitem has a submenu with several menuitems. Your mouse is currently over the top menuitem of the parent menu and the submenu from it is open to the right. - Now when you move the mouse toward say the middle of that submenu, you'll probably mouse-over a menuitem below the current one in the parent menu.. - But there are two things that can keep it from becoming the active menuitem.. a timer, and this stay-up triangle. - <bratsche> Anyway, we should think about this some. Indicator icons are small enough that in the case of indicator-sound, going to all the trouble of duplicating this stay-up triangle might be more trouble than it's worth. Judging by the screenshot in qense's bug, the stay-up triangle would cover most the majority of the neighboring indicator icon anyway, so maybe a simple timer would be enough." + Another solution would be to use a timer for closing the current menu + and opening a new one. This is what Windows does for submenus. But it + has the drawback of slowing down browsing, which would be worse for top- + level menus than for submenus. - Illustration of the invisible triangle for submenus: - <http://www.quinn.echidna.id.au/Quinn/WWW/HISubtleties/HierarchicalMenus.html> + GTK already has a more sophisticated solution for submenus, similar to Mac OS: a triangle based on the corners of the submenu and its parent item, in which there is a much longer delay for closing the submenu and changing the menu selection. <http://www.quinn.echidna.id.au/Quinn/WWW/HISubtleties/HierarchicalMenus.html> Discussion of the invisible triangle for submenus in GTK: <http://mail.gnome.org/archives/gtk-devel-list/2000-May/msg00118.html> - Gtk+ already has triangular bounding boxes for sub-menus. This code - should also be applied to the top-level and not just the sub-menus. + However, this feature in Gtk+ has been broken since July 2013. + <https://bugzilla.gnome.org/show_bug.cgi?id=710388> The code, once + fixed, should be applied to menu titles as well. + + More information: <http://thomaspark.co/2011/10/making-menus-escapable/>
