TextItems in QTreeview are showing "..." if resized (instead of a horz. scrollbar)

[nightghost]

Hello,

I'm using a QTreeView to show data. Everything is fine. Excepted for one thing. Instead of showing a showing a horizontal scrollbar if the treeview is resized the text is shortened and shows "..." at the end (see the last four item in the example).

Example:

(The horizontal scrollbar is shown, because i used setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOn );, but it is useless as seen on the screenshot)

I'm using the default delegate with a custom model. How can I get a working scrollbar instead of "..."
