popup_for_device
Description:
Pops up the menu of this.
Note:
Use [class@Gtk.DropDown]
Note that currently this does not do anything with the device, as it was previously only used for list-mode combo boxes, and those were removed in GTK 4. However, it is retained in case similar functionality is added back later.
Parameters:
| this |
a `GtkComboBox` |
| device |
a `GdkDevice` |
