[Qt-interest] which key(s) pressed for current widget?

[James Yan]

hey all,

 i create a widget where i can draw and move points on it, and allow user to
move points with two methods, so i want to separate two methods with user's
key press: if CTRL is pressed or not while mouse moved.

so i think it can be impletmented with keyPressEvent / keyReleaseEvent in
this way:

mywidget::keyPressEvent( QKeyEvent * event )
{
   key = event->key(); //save which key pressed
}


mywidget::keyReleaseEvent ( QKeyEvent * event )
{
   key = -1; // no key pressed from now
}

mywidget::movePoint()
{
    if(key == CTRL)
   {
        //move points with method #1
   }
   else
   {
        //move points with method #2
   }
}

but the result of above idea and code do not works, i already setFocusPolicy
so widget can revice key.
any wrong with it? my problem can be solved with keyPressEvent /
keyReleaseEvent?
