[PySide] QTableView.setMinimumSectionSize() not working after model reset

[Frank Rueter | OHUfx]

Hi all,

I am working with a QAbstractTableModel and a QTableView, and need to 
reset the entire model during a sessions.
However, when columns are added they do not honour the 
QTableView.horizontalHeader().minimumSectionSize() and turn up too small.
The moment I touch the section divider they snap to the right size 
though, so it feels like I’m missing a signal to ensure the 
QHeaderView’s update.
Any ideas?
There are so many signals one can emit that I am slightly confused now 
about which ones may or may not help.

Here is my test block to reset the QAbstractTableModel, messily emitting 
signals left right and center to see which ones could help:

|self.beginResetModel() self.layoutAboutToBeChanged.emit() 
self.__collectCellData() # provides all data to rebuild the model 
self.endResetModel() self.modelReset.emit() 
self.headerDataChanged.emit(QtCore.Qt.Orientation.Vertical, 0, 
self.rowCount()) 
self.headerDataChanged.emit(QtCore.Qt.Orientation.Horizontal, 0, 
self.columnCount()) self.dataChanged.emit(self.index(0, 0), 
self.index(self.rowCount(), self.columnCount())) self.layoutChanged.emit() |

​
I also tried connecting to the model's columnsInserted signal but to no 
avail.


Cheers,
frank
