python-3.x - 将键盘快捷键添加到 GIo.Menu

Question

我正在尝试将 accelgroup（键盘快捷键）添加到 Gio.Menu 项目。但我还没有找到一种方法来做到这一点。就像，在这个例子中，我想用<Ctrl>+o

filemenu = Gio.Menu()
filemenu.append("Open","win.open")

accelgroup=Gtk.AccelGroup()
self.add_accel_group(accelgroup)

# Open menu
open_action = Gio.SimpleAction(name="open")
# this line is problematic
open_action.add_accelerator("activate". Gdk._keyval_from_name("O"))
open_action.connect("activate", self.MenuElem.file_open_clicked)
self.add_action(open_action)

我怎样才能做到这一点？

Answer 1

您不会将键绑定添加到 Gio.Action 本身，而是将它们添加到小部件或应用程序，例如：

app = # My Gtk.Application instance
window = # My Gtk.ApplicationWindow instance
action = Gio.SimpleAction.new('open', None)

window.add_action(action)
app.add_accelerator('<Primary>o', 'win.open', None)
# The 'win.' prefix is because it was added to a Gtk.ApplicationWindow
