Wt

WItemDelegate does not check whether dynamic casts were successful in editState and setEditState, even though the editor could have been replaced by somebody overriding createEditor.

As with updateModelIndex, these two methods should do nothing in case a user forgot to implement them - instead of crashing the software.

I created a PR on github (https://github.com/emweb/wt/pull/234) to modify this behavior.
