QSystemTrayIcon, change behavior

[hbatalha]

I just learned how use the QSystemTrayIcon, however it works in a way that is not exactly what I want.

This is the code(snippet) that I am using :

void MainWindow::on_button_clicked()
{
// tray is declared in the class and initialized with the icon in the constructor
    tray->show();         
         
   tray->showMessage("A test", "this has proved to be working", QSystemTrayIcon::NoIcon );
         
   / tray->setVisible(false);
         
}            

With this code the tray is shown as expected but after the tray disappears the icon stay here:

which is something I don't want since it has no use there(didn't set any contextmenu)

If after I showMessage() I set the tray to invisible it removes the icon from there but the notification won't stay in the notification area.

Is there a way to change this behavior?

Hi,

A tray icon does not necessarily have a contextual menu, it might also just provide some information.

Your situation is not really clear.

What do you want from your system tray icon ?

[hbatalha]

@SGaist thanks for the quick reply

What do you want from your system tray icon ?

This is the message it shows.

After this message disappears, the icon I set for the tray continues here:

I don't want that.
I can set the visibility to false after showMessage() but then, the message won't stay in the notification area.

I hope I made the question clear.

[SGaist]

So you just want the notification but not the icon ?

[hbatalha]

@SGaist sorry for the late reply

So you just want the notification but not the icon ?

yes, and I want the notification to stay in the notification area

[SGaist]

Then you might have to pilfer the backend code of QSystemTrayIcon since you have no use of it beside the notification part.

Where do I find the code?

[Christian Ehrlicher]

In the git repo or e.g. here: https://code.woboq.org/qt5/qtbase/src/widgets/util/qsystemtrayicon.cpp.html

@Christian-Ehrlicher thank you
Is there any step by step on how to build it from source, or in which category here in the forum can I post a question?

[Christian Ehrlicher]

Why do you want to compile Qt5 now?
See https://doc.qt.io/qt-5/build-sources.html

[hbatalha]

@Christian-Ehrlicher just out of curiosity

[hbatalha]

@SGaist

What exactly did you mean by "pilfer the backend "? Should I remove some code?

[hbatalha]

@Christian-Ehrlicher or https://doc.qt.io/qt-6/windows-building.html

No, you should get some inspiration from it.

@SGaist
I don't see how that will help me achieve what I want, I went through the code in @Christian-Ehrlicher 's link but couldn't find anything that would help me, I might be missing some things.

[SGaist]

You have to do some more spelunking and go to the backend side of things to get the Windows specific implementation.

[hbatalha]

@SGaist I will try
