PR: Add PySide6 support for qta-browser

[kumattau]

This PR is for that qta-browser supports PySide6.
I tested the PR on Linux(x11) and multi-screen.

Please note that qta-browser cannot show correct icons until PySide6's PYSIDE-1685 is released.
By the following workaround, qta-browser works with current PySide6 6.2.0,
but I does not apply the workaround because I think it is not responsibility of qta-browser.

Fixes #170

Hi.
How about using setFamily() instead of the qfont constructor?
Maybe it can be used with both qt5 and qt6.

@5yutan5, Thank you for the comment.

I checked it worked well on pyqt5 and pyside6.
I added the commit.

@kumattau, No problem. Thanks for this work👍

About QApplication.desktop() problem, if you use QGuiApplication.primaryScreen() does not require exception handling.
But I don't understand the difference between QGuiApplication.primaryScreen() and QGuiApplication.screenAt().
Perhaps this suggestion isn't really needed.

Hi, @5yutan5

But I don't understand the difference between QGuiApplication.primaryScreen() and QGuiApplication.screenAt().

There is the following difference if screen#0 (primary) and screen#1 (secondary) exist.

• QGuiApplication.primaryScreen() always returns screen#0 (primary).
• QGuiApplication.screenAt(cursor's position) returns the screen where there is a cursor.

The original code and my fix show a window on the screen where there is a cursor,
but your suggestion always shows a window on the primary screen regardless of a cursor position.

@kumattau, ok.
Is this mean that using QGuiApplication.primaryScreen() in multiscreen may open the window in unexpected size or screen?
I test only one screen so I couldn't find the difference😅

@5yutan5, yes that's right.

Thank you @kumattau for noticing this and submitting the corresponding fixes! I left some suggestions for the except blocks but otherwise this LGTM 👍

[kumattau]

@dalthviz thank you for the review.
I applied all your suggestions and updated comment.
