I'm trying to implement a drop down list in an Ubuntu app using Glade (GTK+3) and Python. I can get the ComboBoxText to display, populated with strings. However when I close the window it is contained in and then re-open it, the combobox is not there, just a completely blank window.
I added the ComboBoxText widget in question to a window in Glade. I then added this code in my Python programme:
def on_button_edit_clicked(self, widget): """ display list of events already stored, and allow deletion """ self.combo = self.builder.get_object('combo_box') self.store = Gtk.ListStore(str) self.store.append(['hello']) self.store.append(['goodbye']) self.combo.set_model(self.store) event_editor = self.builder.get_object("event_editor") event_editor.show()
I even tried destroying the widget to see if that helps:
def on_event_editor_destroy(self, widget): self.combo.destroy() self.store = Gtk.ListStore(str) self.combo.set_model(self.store)
I have since tried some alternative code, that included a CellRendererText object, but still no luck.
These are my sources (unfortunately I can't link to them all as I don't have enough of a reputation):
I created a Gtk.ListStore(), then I created a Gtk.CellRendererText(), then I created a Gtk.ComboBox(). This was all in-line with example 13.3 here.
Nothing works. When I open the combobox window a 2nd time, it is just a blank window. Can anyone help please?
