environment:
The GNOME Builder generated project use GtkTemplate to interpret ui, But I change it to use Gtk.Builder to interpret. After modifying, it does not work. And I can not see any error message.
class Application(Gtk.Application):
def __init__(self):
super().__init__(application_id='org.gnome.Ee',
flags = Gio.ApplicationFlags.FLAGS_NONE)
def do_startup(self):
print('do_startup')
Gtk.Application.do_startup(self)
builder = Gtk.Builder()
builder.add_from_resource("/org/gnome/Ee/window.ui")
print(builder)
self.builder = builder
def do_activate(self):
print("do_activate")
win = self.props.active_window
if not win:
win = self.builder.get_object("EeWindow")
print(win)
win.present() # not work, can not see the window
I have upload the demo code to Github: https://github.com/Honghe/gnome_builder_demo
Any help will be appreciated!
The application does not know about the window so it exits immediately. You need to call win.set_application(self) after you created an instance of the window.
