Sorry, I now have time issues and don’t have access to a Windows machine. I had problems running WinUI on a virtual machine inside Parallels Desktop arm64 SecondWindow is experimental in nature and has a lot of winapi calls to implement transparency and borderless window, and so it's quite time consuming to test all the options and fix it for now for me. I'd be happy to accept PR if you're interested in doing it. The WinUI code for SecondWindow is concentrated in one file and, I hope, is quite clear - https://github.com/HavenDV/H.NotifyIcon/blob/master/src/libs/H.NotifyIcon.Shared/TaskbarIcon.ContextMenu.WinUI.SecondWindow.cs
It actually crashes when instantiating a new window here:
In TaskbarIcon.ContextMenu.WinUI.SecondWindow.cs
I am not very experienced with .net, but I think this likely is a runtime bug. Instantiating without passing any arguments also results in a crash.
It would be great if someone took the time to check if rolling back to one of the previous versions of WindowsAppSDK helps
1.3 works. We got some other issue with 1.3 so it would've been nice if this worked, but that's life.
I tried the popup message mode, but it seems that the click events aren't being triggered? Do you have a clue on that?
The active window mode works, but it renders behind the system tray blob.
In the latest package version, I found that this issue still occurs in the debugging mode of Visual Studio 2022, but I tried to run it directly without debugging and found that it also has issues. And I added global exception capture in the App. xaml file, which doesn't seem to affect the program's operation, but it will hinder me from debugging the application.
Same problem here, the application crashes in debugging mode after upgrading the WindowsAppSDK to 1.4. It worked fine with 1.3.
The temporary solution is to build the ContextFlyout programmatically and not assign it to the TrayIcon control.
var menuFlyout = new MenuFlyout();
var showHideWinCmd = new XamlUICommand()
{
Label = TranslateUtils.Translate("menu_show_hide_window"),
Description = TranslateUtils.Translate("menu_show_hide_window"),
IconSource = new SymbolIconSource() { Symbol = Symbol.OpenPane },
};
showHideWinCmd.ExecuteRequested += ShowHideWindowCommand_ExecuteRequested;
menuFlyout.Items.Add(new MenuFlyoutItem()
{
Command = showHideWinCmd
});
var exitAppCmd = new XamlUICommand()
{
Label = TranslateUtils.Translate("menu_exit_application"),
Description = TranslateUtils.Translate("menu_exit_application"),
IconSource = new SymbolIconSource() { Symbol = Symbol.ClosePane },
};
showHideWinCmd.ExecuteRequested += ExitApplicationCommand_ExecuteRequested;
menuFlyout.Items.Add(new MenuFlyoutItem()
{
Command = exitAppCmd
});
TrayIcon.LeftClickCommand = showHideWinCmd;
#if !DEBUG
TrayIcon.ContextFlyout = menuFlyout;
#endif
