Make a application that create a QSystemTrayIcon and no taskbar entry

stucremon

@#include <QWidget>
#include <QApplication>
#include <QSystemTrayIcon>

int main(int argc, char** argv)
{
QApplication app(argc, argv);
QWidget w1;
QSystemTrayIcon icon(QIcon("./icon.png"), &w1);
icon.show();
app.setQuitOnLastWindowClosed(false);
return app.exec();
}@

When I run this code, sometimes it make no taskbar entry but sometimes it does
Can anyone explain me why?
And how can I make a application that only make a systemtray icon without taskbar entry?
I am using Linux Mint with MATE

It doesn't work. Sometimes it make a taskbar entry.
This taskbar entry remain even after i have killed this program

It's common for all taskabar applications that was not quit but terminated.
You have to add some custom menu etc. with exit action. Calling QCoreApplication::quit() might be enough.

I have tried some code that i found in internet. All of them work corectly in Windows7 but not in LinuxMint with MATE.
Are there somethings incompatible?
I use Qt 5.0.2

I have the same problem:

Perhaps the problem is Linux Mint, and not Qt? Perhaps Linux Mint always creates a task-bar entry by default, whether it is requested by the application or not?

I use Debian 7 instead of Linux Mint. With Qt 4.8.4 all works well.
