QTreeView and spanning columns

[TorstenG]

Well, I haven't found a good solution, but a way to to it.

I call setFirstColumnSpanned() directly from my model from the data() method when this item is accessed.
Of course, the model needs to know its view ... and this causes a bit headache but it works for me.

Hi, can you please post here how did you call the function setFirstColumnSpanned from the data() function. I am having similar problem but didn't find any solution to this.
