Glade file erzeugt fehler Gtk-CRITICAL

sedi · Donnerstag 19. Mai 2016, 16:04

Hallo zusammen...

Beim Einlesen des Gladefiles kommt ständig dieser Fehler:

(gladewindow.py:14861): Gtk-CRITICAL **: gtk_menu_item_set_accel_path: assertion 'accel_path == NULL || (accel_path[0] == '<' && strchr (accel_path, '/'))' failed

Ohne jede Spur von Erfolg versuche ich bereits seit mehreren Stunden diesen Fehler zu beheben

Hier das Gladefile (erstellt mit Glade 3.18):

Und hier der Testcode:

Code: Alles auswählen

#!/usr/bin/env python3
# -*- coding: utf-8 -*-


import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gio, Gtk, Gdk


builder = Gtk.Builder()
builder.add_from_file("appview.glade")

window = builder.get_object("window1")
window.show_all()

Hoffe ihr habt einen guten Rat

@sedi: Wenn ich mir die Bedingungen an `accel_path` in der Ausgabe anschaue, dann sind die mindestens von dem ersten Wert, den ich dafür in der XML gefunden habe, nicht erfüllt.

sedi · Donnerstag 19. Mai 2016, 18:17

Äh sorry, das habe ich vergessen:
Alle Variationen rund um die Zeile

<property name="accel_path">CTL+W</property>

haben ebenfalls nicht funktioniert:
a) entferne ich die Zeile komplett, so geht das Fenster kurz auf und verschwindet dann wieder
b) Rahme ich

CTL+W

ein

<CTL+W>

dann tritt das gleiche wie in a) auf

Ausgangspunkt für mein kleines Vorhaben in PyGObject und Glade war übrigens http://python-gtk-3-tutorial.readthedoc ... ilder.html - falls das irgendwas bringt.

Hab meinen - dummen - Fehler selbst gefunden: Habe das

Code: Alles auswählen

Gtk.main()

vergessen - sh......

http://lazka.github.io/pgi-docs/#Gtk-3. ... k.AccelMap

The accelerator path must consist of “<WINDOWTYPE>/Category1/Category2/.../Action”, where WINDOWTYPE should be a unique application-specific identifier that corresponds to the kind of window the accelerator is being used in, e.g. “Gimp-Image”, “Abiword-Document” or “Gnumeric-Settings”. The “Category1/.../Action” portion is most appropriately chosen by the action the accelerator triggers, i.e. for accelerators on menu items, choose the item’s menu path, e.g. “File/Save As”, “Image/View/Zoom” or “Edit/Select All”. So a full valid accelerator path may look like: “<Gimp-Toolbox>/File/Dialogs/Tool Options...”.
