KeyPressEvent behaves strange, skips the F key.

[pir]

Hi!

I have reimplemented the keyPressEvent to do some stuff. But I can't make it work. The purpose of the key events is to do something and then a GLWidget is supposed to be redrawn to show the result. It works with some keys, but nothing happens when sertain keys are pressed. Or at least nothing is done until I do something else that requires the GLWidget to be redrawn. When that is done, the result is shown.

Here is some code, the F key is the one not working. The A key works just fine, also the Shift and all the rest. Maybe I haven't called setFocusPolicy ( ) correct. I've tried to insert it in the mousPressEvent(), but that didn't do anything.

I tried to print some trace text, but that didn't come out as I hoped. Look in the code...

void keyPressEvent ( QKeyEvent *event )
{
      std::cout<<"this is not always written when a key is pressed..."<<std::endl;
     switch ( event->key() )
     {
        case Qt::Key_Shift:
       {
         // WORKS FINE
       }
       break;
 
       case Qt::Key_A:
       {
         // WORKS FINE
        // does something ....
        update ( ); // updates the GLWidget
       }
       break;
 
       case Qt::Key_F:
       {
         // THIS KEY DOESN'T WORK!
        focusSelection ( );
        update ( );
       }
       break;
 
       default:
          event->ignore ( );
 
     }// switch
 
}// keyPressEvent(QKeyEvent*)

void keyPressEvent ( QKeyEvent *event )
{
      std::cout<<"this is not always written when a key is pressed..."<<std::endl;
     switch ( event->key() )
     {
        case Qt::Key_Shift:
       {
         // WORKS FINE
       }
       break;
  
       case Qt::Key_A:
       {
         // WORKS FINE
        // does something ....
        update ( ); // updates the GLWidget
       }
       break;

       case Qt::Key_F:
       {
         // THIS KEY DOESN'T WORK!
        focusSelection ( );
        update ( );
       }
       break;

       default:
          event->ignore ( );

     }// switch

}// keyPressEvent(QKeyEvent*)
