AutoAdjust columns in a QTreeView

[alexandernst]

How can I make a QTreeView to auto-adjust the wigth of the columns?
The only thing that I found here is resizeColumnToContents(), but this method will make me call it for every column. Isn't there something else?

See QHeaderView::setResizeMode() with QHeaderView::ResizeToContents.

(self.ui.qtreeview.header()).setResizeMode(3)

(self.ui.qtreeview.header()).setResizeMode(3)

To copy to clipboard, switch view to plain text mode 

That works great ! But now I have another 2 problems. The first one is that I can't hide one of the columns, I tried with this:

index = (self.ui.qtreeview.header()).visualIndex(4)
        (self.ui.qtreeview.header()).setSectionHidden(index, True)

index = (self.ui.qtreeview.header()).visualIndex(4)
        (self.ui.qtreeview.header()).setSectionHidden(index, True)

To copy to clipboard, switch view to plain text mode 

The second problem is that I have some qstandarditems that have really long text, and when the text-column is expanded according to the size of the text, the QTreeView will become... scrollable (horizontally). How can I prevent that?

Don't set the resizeMode policy to ResizeToContents for that column (or set it to something else).

Great,

(self.ui.cList.header()).resizeSections(1)

(self.ui.cList.header()).resizeSections(1)

did the trick perfectlly. I also got the first one. I just had to say to the model that it'll have 5 columns, and then I hidded them with

.setSectionHidden(int, True)

.setSectionHidden(int, True)

Really thanks wysota!
