Ha, you are a star! I will try that first thing in the morning!

Thanks!

Hi Frank,

I didn't spot it earlier, but now I saw it. You're manipulating
QHeaderView's sections before setting the model on the view. Most things
you can do with a QHeaderView require a model to be present.

If you move these calls to after a model has been set, everything works.

Hi,

I isolated the problem into a small snippet:

This still crashes for me.

I do get the result I’m after by only setting one resize mode, i.e.:

|header.setSectionResizeMode(5, QtWidgets.QHeaderView.Fixed) |

However, what I’m really after is the behaviour of

|header.setStretchLastSection(True) |

but I need the second last section to stretch while the last one remains
a fixes size.
Is there a way to do this or do I have to write my own header view for that?

Cheers,

Interesting it won't crash for you. I will try it in a different IDE

something wrong with my install.

Must be something in your code; I'd start by double-checking
everything
related to the header data in your model.

Hi all,

Is this a bug or am I doing something wrong?

Hi,

I isolated the problem into a small snippet:
https://gitlab.com/snippets/1744780

This still crashes for me.

[Interest] crash when using multiple setSectionResizeMode() calls in QTableView

2018-08-12 Thread Frank Rueter | OHUfx 

Hi all,

using PySide2 I am trying to set different resize modes for each of my 
columns in a table view, but as soon as I set more than one I get a crash.


Here is what I do:

|class MyView(QtWidgets.QTableView): def __init__(self, parent=None): 
super(MyView, self).__init__(parent) header = self.horizontalHeader() 
header.setSectionResizeMode(0, QtWidgets.QHeaderView.Fixed) 
header.setSectionResizeMode(1, QtWidgets.QHeaderView.Interactive) |


Is this a bug or am I doing something wrong?

Cheers,
frank
