PointerPressed and PointerReleased events in buttons

[os-lmo]

Hi,

In the button control, I realized that the PointerPressed and PointerReleased events are only triggered when I press/release the mouse right button in a button. If I press the left button, only the click event is triggered.

My question is: why the PointerPressed and PointerReleased events are not triggered with a left mouse click in a button (keeping the mouse over the button) ?

That's because the event was already handled (e.Handled = true). You can subscribe to events even if they're handled like this:

button.AddHandler(Button.PointerPressedEvent, (sender, e) => { }, handledEventsToo: true);

Thanks. Adding the handledEventsToo, it worked.

Just one more question: I want to globally listening all pointer released events (just once per release) hence I am using the AddClassHandler:

Window.PointerReleasedEvent.AddClassHandler((Window target, PointerReleasedEventArgs e) => { }, handledEventsToo: true);

Anyway, these events are not being catched. I am missing anything?

That's because routes is Direct|Bubble by default (i.e. event is directly on Window or it was not handled by an element in the chain starting in the control and going up to the Window. You need to add the Tunnel routing strategy (like bubble, but starts from the root and goes down to the control):

button.AddHandler(
    Button.PointerPressedEvent,
    (sender, e) => { },
    routes: RoutingStrategies.Direct | RoutingStrategies.Tunnel | RoutingStrategies.Bubble,
    handledEventsToo: true);
