TrayIcon, how to show NativeMenu with left mouse button single click ?

[xiaokun]

The default behaviour of TrayIcon to show NativeMenu is right click on it, but right click is more difficult than left click on touchable screen.

 <TrayIcon.Icons>
      <TrayIcons>
          <TrayIcon Icon="/Assets/logo.ico" Clicked="TrayIcon_Clicked">
              <TrayIcon.Menu>
                  <NativeMenu>
                      <NativeMenuItem Click="OnNetSettingsClicked" Header="Net..."/>
				<NativeMenuItem Click="OnMaskSettingsClicked" Header="Mask..." />
				<NativeMenuItemSeparator />
                      <NativeMenuItem Click="OnExitClicked" Header="Exit..." />
                  </NativeMenu>
              </TrayIcon.Menu>
          </TrayIcon>
      </TrayIcons>
  </TrayIcon.Icons>

We can add Clicked event to TrayIcon, but i found no way to open NatvieMenu programmatically in it.

Does anyone know of any other solution?

Left click currently executes Clicked event.
It should be possible to also handle touch message to open the menu, but not clear what to do with Clicked event then.

@maxkatz6 This should be resolved better way. Perhaps, for example, the TrayIcon could have a ShowMenu function?

Currently, on Windows, to display the menu in response to a left-click, I had to search the application's window list and send WM_USER message to the window handling the tray. Which is not an elegant solution ...

TryShowMenu API is better than nothing, I suppose. Non-windows platforms should be considered.

Here's a Window's only solution I found to show the menu on a left click.

private void OnTrayIconClicked (object? sender, EventArgs e) {
	// Get this tray icon's implementation
	ITrayIconImpl? impl = (ITrayIconImpl?)GetType ()
		.GetProperty ("Impl", BindingFlags.NonPublic | BindingFlags.Instance)?
		.GetValue (this);

	// Get the Windows tray icon implementation type
	Type? type = AppDomain.CurrentDomain.GetAssemblies ()
		.Where (a => a.FullName?.StartsWith ("Avalonia.Win32") ?? false)
		.SelectMany (a => a.GetTypes ())
		.FirstOrDefault (t => t.Name == "TrayIconImpl");

	// If the Implementation and type are not null
	if (impl != null && type != null) {
		// Get the OnRightClicked method
		MethodInfo? methodInfo = type.GetMethod ("OnRightClicked",
			BindingFlags.NonPublic | BindingFlags.Instance);
		// Invoke the method on the implementation
		methodInfo?.Invoke (impl, null);
	}
}
