I try to avoid the XY Problem by saying immediately what I want and then what I get. 😛
So, first of all, I minimize my MainWindow and thoroguh its NotifyIcon ContextMenu I want that my MainWindow reappears.
The problem: the MainWindow doesn't appear/show as Window, but it appears as Icon in the toolbar (see figure 2).
The code:
This is the TrayIcon initializer:
private void InitializeTrayIcon()
{
KyactusTrayIcon = new NotifyIcon();
KyactusTrayIcon.Icon = AppIcon;
KyactusTrayIcon.Visible = true;
KyactusTrayIcon.ContextMenu = new ContextMenu(new []
{
new MenuItem("Chiudi", ExitApplication),
new MenuItem("Mostra", ShowMainWindow),
});
ShowNotification(@"Ciao " + Globals.CurrentUser.Name + @"!", @"Benvenuto su Kyactus");
}
This is the delegate responsible to show the minimized MainWindow (not working at all):
private void ShowMainWindow(object sender, EventArgs e)
{
WindowState = WindowState.Normal;
Topmost = true;
Show();
Activate();
}
This is what happens when the MainWindow is minimized by clicking the [-] button (ie the Hide() method):
private void MainWindow_OnStateChanged(object sender, EventArgs e)
{
switch (this.WindowState)
{
case WindowState.Maximized:
ShowNotification("Bleah!", "Questo è proprio brutto! :(");
break;
case WindowState.Minimized:
Hide();
ShowNotification("Avviso", "L'applicazione è ora minimizzata qui");
break;
case WindowState.Normal:
break;
}
}
Step one. The method MainWindow_OnStateChanged will be invoked when click on [-]:
Step two. The window disappears (ok) and the Tray icon appears (ok). Then I click on 'Mostra' (translated as 'Show') and the ShowMainWindow delegate will be invoked
Step three. This is the final step, that is, what I do not expect. The MainWindos 'lives' as an Icon in the toolbar. But I can't see it as a Window.
Please note that I have not this problem when I close the window by clicking [X] instead of [-]. So, my suspect is the MainWindow's Window.State. I tried to restore it implementing the WindowState.Normal into the ShowMainWindow, but nothing.
Update: if is use WindowState.Maximized in the ShowMainWindow method, I can see the window again, but it is maximized and this is bad and ugly.
Just change the order of operation when showing the window
private void ShowMainWindow(object sender, EventArgs e)
{
Show();
WindowState = WindowState.Normal;
Topmost = true;
Activate();
}
