PyQt5 Multiple Level Header View

[mire22]

Hi!

I would like to make a multiple level header view for a QTableView. The example that you made in C++ https://github.com/eyllanesc/stackoverflow/tree/master/questions/46469720 is exactly what I want but in Python. So I translated all the code from C++ to Python with PyQt5 library. The results are that the vertical header works well but not the horizontal header: only the first line is displayed. I compared again and again the full code to find the error but I can't fix it.

You will find the full Python code attached and screenshots: MultipleLevelHeaderView_python.zip In GridTableHeaderView > PaintSection, I printed the cells data and the horizontal header cells are well created and painted... But at the end, they don't show.

Thank you for your help! Rémi

• Screenshot of the github web page https://github.com/eyllanesc/stackoverflow/tree/master/questions/46469720:

• Screenshot when I run your C++ project:

Minor issues are that I don't see the horizontal lines in the headers and the cyan background doesn't show.

• Screenshot with the Python files translated from your C++ project:

I don't have the 2 lines in the horizontal header ("cell5" and "cell6" are lacking). Moreover "cell2" and "cell3" are not vertically centered in the vertical header.

Environment:

• OS: Windows 10
• Python version: Python 3.7.3
• PyQt5 version: PyQt5 version 5.9.2 - Qt version 5.9.3

@mire22 When executing your code in Linux with PyQt5 5.15 I get:

So I will review because some cells are not shown, the style seems strange to me but try putting: app.setStyle("fusion"), in addition to that tell me what you get when you run: print(app.style().metaObject().className())

With app.setStyle("fusion") the lines and the cyan background appear: Command print(app.style().metaObject().className()) returns:

• QWindowsVistaStyle without app.setStyle("fusion")
• QFusionStyle with app.setStyle("fusion")

Hi, I just tried with Qt version 5.9.6 and it is the same. I can't see how to solve this issue. Thank you for your help. Rémi
