[Octave-bug-tracker] [bug #50567] Qt 4.6.2 compiler error on MiddleButton

[Dan Sebald]

Follow-up Comment #1, bug #50567 (project octave):

Here's the list of event options:

http://doc.qt.io/qt-4.8/qml-mouseevent.html#button-prop

At the top of that page is the note:

"Since: Qt 4.7"

I would say that the following hunks of code should be conditioned on Qt >=
4.7 then:


$ grep MiddleButton */*/*
src/m-editor/file-editor.cc:       me->button() == Qt::MiddleButton)
src/qtinfo/webinfo.cc:      me->button() == Qt::MiddleButton &&


It would mean those mouse features don't exist for Qt < 4.7, or perhaps there
is a more primitive way of getting the same info.
