QML SystemTrayIcon icon from QML module not showing

MaxL

Hello.

I am facing a bug that I cannot understand on macOS using Qt 6.7.2 when trying to display an icon for the SystemTrayIcon QML widget.

This is the Main.qml loaded with engine.loadFromModule("qmlModule", "Main"); :

SystemTrayIcon {
    property Window window: Window {
        visible: true
        width: 400
        height: 400
       Image {
             anchors.fill: parent
             source: "assets/icons/bad.png"
      }
   }
    icon.source: "assets/icons/bad.png"
    visible: true
}

For some reasons, the icon.source does not work, nothing is visible in the system tray while there is no problem in the Image with the same asset.

Assets are added to the QML module with the RESSOURCES option of qt_add_qml_module CMake function.

Maybe it is also linked but the showMessage from the SystemTrayIcon also does not work.

I have tried the Qt sample project Systray and it works well (icon and showMessage) but it is using QWidget.

Any idea on what is going on ?
Thanks.

Then check with qrc:/myproject/qml/assets/icons/bad.png . icon.source is a url so it requires a scheme hence the qrc:/. It should be the same for Image though.

Hi,

I haven't used that yet but intuitively since you mention resources, I would think that you need to prefix the path with qrc:/.

Both path should then be qrc:/assets/icons/bad.png.

That is what I thought at first.

But using qt_add_qml_module and especially the RESOURCE argument it will create a qrc file with aliases.

For instance it creates this qrc file:

<RCC>
  <qresource prefix="/myproject/">
    <file alias="qml/assets/icons/bad.png">`project_path`/qml/assets/icons/bad.png</file>       
  </qresource>
</RCC>

If I follow how resource file works and especially prefixes and alliases, I should be able to reference the file with :/<prefix>/<file alias>.

Therefore, in my case, I should be able to use :/myproject/qml/assets/icons/bad.png but it does not work. It only work with assets/icons/bad.png and only for the Image, not the SystemTrayIcon. As I am writing this, I think I understand why it works that way (at least for the Image) as it is a relative path pointing to the "local resource".

Thanks it works that way.
I thought I tried this way but maybe I made a mistake somewhere.
Anyway it works for all of the component (Image, SystemTrayIcon and MenuItem)
