[Octave-bug-tracker] [bug #57635] Editor often has focus but no cursor until clicking elsewhere and then clicking in editor

[Hg200]

Follow-up Comment #33, bug #57635 (project octave):

Ahhh - that makes a lot more sense! Thank you for pointing out this small but
important difference ;-)

I configured gdb to print a backtrace after a breakpoint is hit and let gdb
continue automatically. Because switching between the GUI and the gdb console
creates notify-events. It is like you said:

Scenario A:

1.) Two tabs are opened and one is closed with the mouse =>
m_edit_area->setFocus () is executed twice for the reasons
file_editor::active_tab_changed(int) and
file_editor::handle_tab_remove_request()
2.) Reimplementation octave_qscintilla::focusInEvent *is not* triggered. In
the GUI the focus is lost.


Scenario B:

1.) Two tabs are opened. Click the tabs with mouse to bring one into
foreground => m_edit_area->setFocus () is executed once because of
file_editor::active_tab_changed(int)
2.) Reimplementation octave_qscintilla::focusInEvent *is* triggered. In the
GUI the focus is correctly transfered.

This is odd ;-( The implementation of octave_qscintilla::focusInEvent looks
correct to me.
