As an exercise I tried to create the window.ui xml file below with glade UI editor from scratch. I have already learned that my current glade version 3.18.3 does not support stack and stack switcher, but that will change soon with version 3.20. But I was not able to generate the starting template, that is the line <template class="ExampleAppWindow" parent="GtkApplicationWindow"> from glade tool. What is the trick? ~/Downloads/gtk+-3.20.1/examples/application10 $ head window.ui <?xml version="1.0" encoding="UTF-8"?> <interface> <!-- interface-requires gtk+ 3.8 --> <template class="ExampleAppWindow" parent="GtkApplicationWindow"> <property name="title" translatable="yes">Example Application</property> <property name="default-width">600</property> <property name="default-height">400</property> <child type="titlebar"> <object class="GtkHeaderBar" id="header"> <property name="visible">True</property> _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
