You have all the details in the Signals And Slots chapter of Qt's documentation.

Hi,

If you don't care about the child you are dragging, why not just return the data you're interest in in your mimeData method ?

Then you have to go to the Build & Run settings and under General change the value of "Stop application before building".

Great !

Yes, you're right, i should check the bug database before making post, but the bug means, in specific case, a specific functionality is not working as accepted, and usually it doesn't happen a entire thing is not working and that is a bug. thus why bug database didn't get my attention and i was thinking, it is a problem at my side.

I Tried QAxObject instead of QAxWidgetand CoInitialize() there..... it works fine in another thread.
