To set focus on circumference circles when key is pressed

[wysota]

The keys may be intercepted globally by some other application (like the desktop or the system itself) but my remarks on the paint event still stand.

t why not for F10 and F11?

The first thing to test is to see if your application does indeed the get key events.
Set a break point in your keyPressEvent(), and see if they are being caught.

Thanks for everyone. Need to call update function now its working fine and below is the code snippet

switch ( event->key() )
{
case Qt::Key_F11:
nextBoltHoleCircle = TRUE;
update();
break;
case Qt::Key_F10:
prevBoltHoleCircle = TRUE;
update();
break;
case Qt::Key_Enter:
needToDrawCircle = TRUE;
update();
break;
default:
QWidget::keyPressEvent(event);
}

switch ( event->key() )
{
case Qt::Key_F11:
nextBoltHoleCircle = TRUE;
update();
break;
case Qt::Key_F10:
prevBoltHoleCircle = TRUE;
update();
break;
case Qt::Key_Enter:
needToDrawCircle = TRUE;
update();
break;
default:
QWidget::keyPressEvent(event);
}

Could you tell me if your program works properly if you press F10 or F11 and then start resizing the dialog?

[soumya]

ya its working fine

[wysota]

With the paintEvent() you posted earlier? Or did you change it? Could you post the complete code of your widget here as an attachment?

[soumya]

Hi,

I have sent the entire code in the attachment it works fine

I'm afraid your application doesn't work on my system, I can't see any "holes" and you disabled resizing the dialog so I don't know how could you say that your application works when the dialog is resized The code is broken, believe me.
