Select Multiple Nodes With Mouse Does Not Highlight Uppermost Node

Python 3.8.5, PyQt version 5.15.1

Windows 10 AMD64 (build 10.0.19041) SP0

When I click on a node in the outline pane, hold the shift key and then click on a later node - expecting all the nodes between clicks to be selected - the initial node clicked on loses its highlighting.  I don't know if that means it isn't selected or that that it is still selected though it is no longer highlighted.

I expect that the initial node will also be selected and highlighted.

Thanks for this report. This looks like a Qt bug.

Traces show that qtree.onItemClicked is called directly from the main loop. Calling g.pdb() at the start of qtree.onItemClicked shows that the faulty tree highlighting has already happened by the time qtree.onItemClicked is called.

Besides the behaviour you mention, if I shift-click more than once the previously-selected node is de-highlighted, no matter where it is. So if I extend the selection, an unselected node is shown in the middle of extended selection.

There is nothing Leo can do about this because the bug is happening before Leo gets control.

Could you tell if it's only a highlight problem or if the selection itself is affected?

Leo's selection logic is in no way involved.
