[Octave-bug-tracker] [bug #59375] [Doc pane] Function index largely dysfunctional

[John W. Eaton]

Follow-up Comment #12, bug #59375 (project octave):

The QHelpIndexWidget::showLink function from 5.15 (shown in comment #10,
copied from the 5.15 sources used to build 6.0.92) emits the
documentsActivated and linksActivated signals if the list returned from
documentsForKeyword has more than one element, or the documentActivated and
linkActivated signals if there is only one element in the list.

I tried tracing this with gdb but couldn't get good info so I added some
old-fashioned print statements that showed the showLink function not emitting
any signals because the list returned by documentsForKeyword was empty.  I
have no idea why.

I've since built 6.0.92 with Qt 5.14.2 and the links work as expected.

Unless there is a quick fix for this problem using Qt 5.15, then my solution
is to build the 6.1 release using Qt 5.14.2.
