Dragging widgets to window won't work

Question

I'm using Qt Creator for several months now and from time to time, I get a problem dragging widgets like buttons, line edits and so from the toolbox to the window.

I try by removing the layouts but still get the same issue.

I use Qt Creator 2.4.0 on OS X 10.7.2

Thanks for helping

Answer 1

I fixed this problem by upgrading Qt Creator to version 2.4.1 on OS X

The solution described above by @spyke might also be helpful for Windows users.

It case there is a dead link, the solution for Windows says :

I was using Qt Designer for Qt Jambi built with Qt 4.6.4 on Windows 7 ×64 when this problem occurred. After a while I realized that the problem was not only in Qt designer, but in Windows in general: Explorer, FileZilla and more.

The solution was then found by searching for general Windows 7 drag and drop problems [answers.microsoft.com].

In short: Select a file in Windows Explorer with click and hold left mouse button. While holding the button down, hit the Esc key. Then drag and drop starts working again.
