Reimplementation Minimize button

[clousque]

Sorry, my question was not very clear.

In fact, I have a frameless window with a QPushButton trying to behave like the minimize button. The clicked() signal of the QPushButton is connected to this slot:

void MainWindow::slotMinimizeWindow()
{
   this->setWindowState(Qt::WindowMinimized);
}

void MainWindow::slotMinimizeWindow()
{
   this->setWindowState(Qt::WindowMinimized);
}

To copy to clipboard, switch view to plain text mode 

Hope this helps to understand my question.

Thanks
