Mouse cursor on link hover

[donjan]

Using ReText 8.0.1 on Ubuntu 22.04.

Enabled the WebEngine renderer option (had to pip install PyQt6-WebEngine). With live preview on.

Observed behaviour

When hovering over a link, the mouse cursor stays arrow shaped.

Expected behaviour

The mouse cursor should change into a hand with pointed index finger, as it does in ReText 7.x and in web browsers.

This could be done in webenginepreview.py by adding QCursor to the from PyQt6.QtGui import line and defining the two cursors:

hand_cursor = QCursor(Qt.CursorShape.PointingHandCursor)
arrow_cursor = QCursor(Qt.CursorShape.ArrowCursor)

Then in webenginepreview.py::ReTextWebEnginePreview, once we have the webPage object, hook into it with

webPage.linkHovered.connect(lambda value: self.setCursor(hand_cursor if value else arrow_cursor))

Works for me:

MR upcoming, I'll try to use camel case.
