Question

I am making a application for maping some keyboard shortcuts to some event. So, I need detecting the keyboard shortcuts pressed after clicking a button. For Example, I have a button having text on it "change". When I click on it text on it changes to "press keys" then I need the user to type the shortcut keys he want to map then the text of the button changes to the keys pressed. While surfing the net, I was only able to find the function :

  void MainWindow::keyPressEvent(QKeyEvent *event)
  {
  ...
  }

but it doesn t fulfill my purpose as I need calling this function from the slot function defined so that I can detect only when I need. Anybody having any idea how this can be achieved?

你们可以设定一个国家变量,表明用户压力了纽伦。然后,窗户应当对下一个关键压力喷口(只有在确定这一国家变数时)作出反应,然后转播国家变数。

void MainWindow::keyPressEvent(QKeyEvent *event)
{
    if (process_key) {
        /* Do whatever needs to be done */
        process_key = false
    }
}
