Menus with custom position: behaviour has changed since GTK 3.10

Created attachment 264904 [details] The menu should be positioned at 50x50px from the bottom left corner Hello, First, thank you for developing GTK+! Since GTK 3.10, I see that the behaviour of menus with a custom position has changed. These menus are displayed by using this function: gtk_menu_popup. The parameter 'func' is used with a correct GtkMenuPositionFunc function. Before, the coordinate given in this GtkMenuPositionFunc function was the starting point of the menu: this point was a corner of this menu. Now, if the menu is positioned at the bottom of the screen, the menu fills the space bellow this point. Thus this point is no longer a corner of this window's menu: it's on the left/right side of this window. Please have a look at the attachment: the menu should be positioned at 50x50px from the bottom left corner. Before GTK 3.10, the menu was above the red point (the red point was the bottom left corner of this menu). Is it a bug? :-) If no, how can have the previous behaviour? Because now this menu is above some contents that shouldn't be hidden when displaying the menu. Best Regards,
Created attachment 264905 [details] Test case: a small menu which should be positioned at 50x50px from the bottom left corner Here is a small test case: when trying to position the menu at 50 x 50px from the bottom left corner, you should see that this menu is not positioned at the right coordinate but above this point: 50 x 0px.
PS: to compile this test case, no extra libs are required, simply launch this command: $ gcc -Wall -g gtk_menu_popup_position.c -o gtk_menu_popup_position `pkg-config --cflags --libs gtk+-3.0`
Note that if we don't add a GtkMenuPositionFunc function, the menu opens at the same position as before: the mouse pointer is always positioned at one corner of this menu.
Hello, It seems that we now have to use the 'natural' size instead of the 'minimum' size. - gtk_widget_get_preferred_size (GTK_WIDGET (menu), &requisition, NULL); + gtk_widget_get_preferred_size (GTK_WIDGET (menu), NULL, &requisition);
We're moving to gitlab! As part of this move, we are moving bugs to NEEDINFO if they haven't seen activity in more than a year. If this issue is still important to you and still relevant with GTK+ 3.22 or master, please reopen it and we will migrate it to gitlab.
As announced a while ago, we are migrating to gitlab, and bugs that haven't seen activity in the last year or so will be not be migrated, but closed out in bugzilla. If this bug is still relevant to you, you can open a new issue describing the symptoms and how to reproduce it with gtk 3.22.x or master in gitlab: https://gitlab.gnome.org/GNOME/gtk/issues/new
