Question

I have a QAbstractItemView that needs to react to single and double click events. The actions are different depending on whether it was single clicked or double clicked. The problem that is occurring is that the single click event is received prior to the double click event.

Is there a recommended way/best practice for distinguishing between the two? I don’t want to perform the single click action when the user has actually double clicked.

I am using Qt 4.6

Answer 1

You can find answer in the thread titled Double Click Capturing on QtCentre forum;

You could have a timer. Start the
timer in the releaseEvent handler and
make sure the timeout is long enough
to handle the double click first.
Then, in the double click event
handler you can stop the timer and
prevent it from firing. If a double
click handler is not triggered, the
timer will timeout and call a slot of
your choice, where you can handle the
single click. This is of course a
nasty hack, but has a chance to work.
