QTreeView hideColumn() has no function

Frank Winter

Hello, I work on a little pyside2 application with a QTreeView which comes from an ui file.

            self.treeView.setModel(model)
    
            self.treeView.hideColumn(2)
            print(self.treeView.isColumnHidden(1)) # False
            print(self.treeView.isColumnHidden(2)) # True

but column no. 2 is still visible. Are there any requirements for hideColumn() to work properly? Same effect with setColumnHidden(x, True).

Don't know if it's important: I use a selectionModel and "SingleSelection" mode with "SelectRows" selection behavior. That all works.

Thanks,
Frank

Hi and welcome to devnet,

Might be a silly question but how many columns does your model have ?

Can you provide a minimal example showing that behaviour you have ?

By the way ~~what bindings are you using ? PySide2 ? PyQt5 ?~~ which version ?

@SGaist thank you very much. The model has 4 columns which are all displayed in the treeview. I will provide an example this evening.

I've tried it with a simplified version with my Item and ItemModel class (derrived from QAbstractItemModel) and... it works, so I don't post an example here. Have to examine the differences now...

I've found the solution. After initializing everything I called header().restoreState() to restore column withs and everything, and this resetted my hideColumn settings.
