spinbox ClearFocus()

[RENOLD]

In my qt code I want to go to another page from 1st page(means I enter the number where I want to go and press enter and that page will be open). To do so I use spinBox,

if(e->key() == Qt::Key_F)
{
spinBox->setFocus();
}

if(e->key() == Qt::Key_G)
{
spinBox->ClearFocus();
}

When I press F it set the focus of spinBox, But the problem is that when once the focus is set I can not come out from that(my Key_G is not detected).
So please help me to come out from that focus so I can go ahead in my project.

Since the spinbox has focus, it receives all key events so obviously your key handlers are only invoked when a particular widget has focus. To circumvent that you can install an event filter on the application object to intercept all events before they reach their targets.

Thanks for your reply,
I am very new in QT.
Can you please tell me how can I install an event filter on the application object.?

You can open Qt reference manual, switch to the index tab and type in "event filter".
