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

[Hg200]

Follow-up Comment #87, bug #57635 (project octave):

>> Are other focus issues (e.g. when closing a file) fixed?

No, because this problem is caused by the damaged proxy chain which is set up
in file-editor-tab.cc and file-editor.cc. If you run the Qt demo code that I
have attached to this bug report: This code demonstrates the tab closing
problem, without autocompletion and without using scintilla. The example jams
Qt with a simple QTabWidget and a proxy chain as it is used in the Octave GUI.
This is really sad.

The problem is solved for me by removing setFocusProxy in file-editor-tab.cc
but if i recall correctly there were problems on windows as mentioned in
comment #46.
