My code:
class MainWindow(Gtk.ApplicationWindow):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.assigned_keys = {
111:False,
113:False,
114:False,
116:False
}
self.set_default_size(600, 250)
self.set_title("MyApp")
evk = Gtk.EventControllerKey.new()
evk.connect("key-pressed", self.key_pressed)
evk.connect("key-released", self.key_released)
self.add_controller(evk)
def key_pressed(self, event, keyval, keycode, state):
if keycode in self.assigned_keys: self.assigned_keys[keycode] = True
if (self.assigned_keys[111] and self.assigned_keys[113]):
print("up + left")
elif (self.assigned_keys[111] and self.assigned_keys[114]):
print("up + right")
elif (self.assigned_keys[116] and self.assigned_keys[113]):
print("down + left")
elif (self.assigned_keys[116] and self.assigned_keys[114]):
print("down + right")
elif (self.assigned_keys[111]):
print("up")
elif (self.assigned_keys[113]):
print("left")
elif (self.assigned_keys[114]):
print("rigth")
elif (self.assigned_keys[116]):
print("down")
def key_released(self, event, keyval, keycode, state):
if keycode in self.assigned_keys: self.assigned_keys[keycode] = False
class MyApp(Adw.Application):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.connect('activate', self.on_activate)
def on_activate(self, app):
self.win = MainWindow(application=app)
self.win.present()
app = MyApp(application_id="com.example.GtkApplication")
app.run(sys.argv)
If press the "up" arrow and then press "left" arrow, the command stops working when you release the left arrow:
elif (self.assigned_keys[111]): print("up")
It turns out that the previous event - pressing the button stops working.
Is there a way to listen for keys being held down? Maybe some other solution?
I tried adding to the code:
event.emit("key-pressed", keyval, keycode, state)
but this triggers a single signal instead of a button press
