on MACX: when I click on a cell and then start dragging, the application crashes at QtnGridTableView.cpp:5486.
"mime" is NULL and of course this lead to an unrecoverable error.
if I check the mime value the problem disappears, for example using the following alternative line:
if (mime != NULL && mime->hasFormat(modelTypes.at(i)))
This problem is version 2.2 specific.
Can be triggered on the examples included with the library.
Even a small dragging, made by the user involuntarily having just clicked the button a little longer than required and moving the mouse 1 pixel during the button press, triggers the problem and make the application unusable.
I don't know if the issue is MACX specific, sorry.
Unfortunately, the error appears on all platforms, not only for MacOSX. It has been fixed in version 2.3, which is already available for download. Workaround for 2.2 is exists, you need to set the option setDragEnabled(false) for the table view of the grid.
