How can I show a Popover menu when there is a right-click on a row in a treeview, or if the context menu key is pressed?
It seems there was once a “button-release-event” that could be connected, but that seems gone now.
For right mouse button:
1 - Create a new Gtk.GestureClick, then set its button to 3 (right mouse button).
2 - Create a function in the widget displayed in the treeview to display the menu when Gtk.GestureClick happens .
3 - Connect the “released” signal from Gtk.GestureClick with this function.
For a pressed key:
Basically the same thing, but item 1 will use a Gtk.EventControllerKey, and in item 3 the connected signal will be “key-released”.
If you are using a Gtk.SignalListItemFactory, items 1 and 3 can be done in the bind phase.
On a side note, “button-release-event” was for Gtk3, in Gtk4 we must use GtkEventControllers for capturing events.
See Gtk – 4.0: Migrating from GTK 3.x to GTK 4 for the old/new equivalences.
Thanks! I understand that and it works.
