Setting Callback Event for Notification

[bagusnl]

Hi!

I want to know how one can call a function when notification is clicked by the user.

Thanks

I don't remember exactly, but I think it was these events.
Not the best inherited names

There doesn't seem to be those routed events found on my instance

What platform are you on? This is only available for WPF. There is no such thing as RoutedEvents in WinUI. I thought about adding regular events to replace RoutedEvents for the WinUI platform for DependencyPropertyGenerator, but never got around to it.
You can still access this from WinUI using the TaskbarIcon.TrayIcon.MessageWindow events, I made this available in the latest version.

You need MouseEventReceived and BalloonToolTipChanged events

Sorry, I forgot to state my platform. But yeah its WinUI. With the new version, now I can invoke the event. This is what I did:

In constructor:

CollapseTaskbar.TrayIcon.MessageWindow.BalloonToolTipChanged += BalloonChangedEvent;

private void BalloonChangedEvent(object o, MessageWindow.BalloonToolTipChangedEventArgs args)
{
    CollapseTaskbar.TrayIcon.MessageWindow.MouseEventReceived += NotificationOnMouseEventReceived;
}

private bool _mouseEventProcessing;
private async void NotificationOnMouseEventReceived(object o, MessageWindow.MouseEventReceivedEventArgs args)
{
    if (_mouseEventProcessing) return;
    if (args.MouseEvent != MouseEvent.BalloonToolTipClicked) return;
    
    _mouseEventProcessing = true;
    BringToForeground();
    await Task.Delay(250);
    _mouseEventProcessing = false;
}

The only minor issue I have now is that the event is not invoked after the notification went into the Notification tray. But I think I can live without it.

Thank you for the help!

Also take a look to https://learn.microsoft.com/en-us/windows/apps/design/shell/tiles-and-notifications/adaptive-interactive-toasts?tabs=appsdk
I think it's more modern way to do notifications in WinUI

Thanks for the heads up on that one, but unfortunately since our app is running as admin, the notification using that method doesn't work
