QML Focus and handling hide command on MacOS Catalina

GGlowack

Hello,

I am having a problem working out a solution to the following problem.
Here is a simplified version of the app showing hiding/showing mechanism:

(QT 6.2.4)

import QtQuick
import QtQuick.Controls
import Qt.labs.platform

ApplicationWindow {
    id: appWindow
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
  
   function showWindow() {
        show()
        raise()
        requestActivate()
    }

    function hideWindow() {
       hide()
    }

    SystemTrayIcon {
        visible: true
        iconSource: "qrc:/images/tray-icon.png"

        menu: Menu {
            id: trayMenu
            MenuItem {
                text: qsTr("Show")
                onTriggered: {
                    appWindow.showWindow()
                }
            }
            MenuItem {
                text: qsTr("Hide")
                onTriggered: {
                    appWindow.hideWindow()
                }
            }
        }
        
        onActivated: function(reason) {
            /// bring appWindow to the front on mouse right click
            if (reason === SystemTrayIcon.Context || reason === SystemTrayIcon.DoubleClick) 
            {
                    appWindow.showWindow() 
            }
        }
    }
}

When I am doing hide -> show using tray icon menu options (left click on the tray icon to get the menu dropdown) window is correctly hiding and showing itself and also correctly handling OS hide event (Ctrl+H).
It works differently when instead of hiding it using hide from system tray I submit Ctrl+H and then click the right mouse button on the tray icon (invoking appWindow.showWindow()). After that window is brought to the front and shown but next Ctrl+H will not hide it anymore.

Adding modality: Qt.ApplicationModal to the appWindow solves this problem since now it will be the only window that handles keystrokes and inputs but this will disable access to SystemTrayIcon when the window is not hidden.

From some testing, this seems to be a Catalina-specific bug because it works fine in the latter OS versions.
I am looking at least for some workaround to this problem.
