[Octave-bug-tracker] [bug #53046] Variable Editor: feature request to make multiple tables visible at once.

[Dan Sebald]

Follow-up Comment #1, bug #53046 (project octave):

I've looked into this a bit.  For reference, I think the way to achieve
multiple V.E. tables visible at once is to use Qt's QMdiArea:

http://doc.qt.io/qt-5/qmdiarea.html

MDI stands for multiple document interface which is a common term:

https://en.wikipedia.org/wiki/Multiple_document_interface

I believe the idea is that multiple documents can be visible at once.

Qt's MDI area can be in "tiled" mode

http://doc.qt.io/qt-5/qmdiarea.html#tileSubWindows

which I'm guessing is similar to the way the Octave GUI main window works in
which subwindows expand to butt up against other subwindows but never overlap.
 I think this is what would be preferred for the V.E.

The nice thing is that QMdiArea has an option tab feature:

http://doc.qt.io/qt-5/qmdiarea.html#ViewMode-enum

For some reason Qt documentation doesn't give a good picture of that tab area,
but just think of the pictures given here:

http://doc.qt.io/qt-5/qmdiarea.html#details

as having a series of tables along the top.
