setGridSize(...) and text eliding

Question

I am using QListView with QFileSystemModel to make a file manager. I am using QListView::ListMode. The problem I am facing is despite settings a grid size, the text does not get elided. Here is the code I am using.

import sys, os

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *

app = QApplication( sys.argv )

fsm = QFileSystemModel()
lv = QListView()
lv.setViewMode( QListView.ListMode )

lv.setResizeMode( QListView.Adjust );
lv.setMovement( QListView.Static );
lv.setSelectionMode( QListView.ExtendedSelection );
lv.setWrapping( True );
lv.setFlow( QListView.LeftToRight );
lv.setTextElideMode( Qt.ElideRight );
lv.setUniformItemSizes( True );

lv.setIconSize( QSize( 48, 48 ) )
lv.setGridSize( QSize( 200, 56 ) )

lv.setModel( fsm )
lv.setRootIndex( fsm.setRootPath( "/path/to/my/folder/" ) )

lv.show()

app.exec_()

What I get is this garbage:

I do not have a clue why this is so? In the case I do not set a grid size, then the icons and text are rendered properly. Is this some Qt bug?

I'm using Debian Sid, Qt5 5.11.3+dfsg1-1, Python3/PyQt5: 3.7.3-1/5.11.3+dfsg-1+b3 I have even tried this with Qt5/C++ and the problem shows up even there.

Answer 1

I do not get what the OP shows in the image, but I get the following:

It shows that the gridSize does not change the size of the item but the separation between them as shown by the ruler.

To change the width of the item I have implemented a delegate:

# ...
class StyledItemDelegate(QStyledItemDelegate):
    def sizeHint(self, option, index):
        s = super().sizeHint(option, index)
        s.setWidth(200)
        return s

# ...
lv = QListView()
delegate = StyledItemDelegate(lv)
lv.setItemDelegate(delegate)
# ...
