[Qt-interest] Mouse double click.

[Shabd Swarup V]

Hi Alex,

Thanks for being patient, but this also not what I'm looking for. In fact, I need just the opposite of this. 
I am actually trying to simulate user behavior through code. So, I need to simulate a double click on an index in a TreeView.

The purpose is related to testing of an application. I had a look at QTestLib, it seemed to be interesting but I was unable to find this functionality through that.

The inputs I have are:
1. QTreeView object.
2. Index on which double click has to be executed.

The operation I need to do is "double click". I do not worry about the action that will be performed once the double click is executed. That is upto the QTreeView object's implementation.

Hope I am able to describe the problem better this time.

Regards,
Shabd

Hi again,

In this case, install an event filter for your treeview that redirects 
the events to a function of MyTreeViewImpl. Take a look at this link 
(provided that you use Qt 4):
http://doc.trolltech.com/4.3/qobject.html#installEventFilter
You can get the position of the double click from the QEvent and then 
get the QModelIndex from the indexAt() function of the treeview.
I hope that this is what you're looking for.

Regards,

Alex
