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

[Dan Sebald]

Follow-up Comment #28, bug #53046 (project octave):

OK, glad that fixed a few things.

As for the focus issue--i.e., that the "floated" variable windows disappear
when out of focus--I can't really debug that without it happening here.  I'll
look for any pertinent Qt setting, but I can't recall seeing anything related
to that.

What's not immediately obvious is that Qt doesn't seem to control the desktop
windowing system.  The windowing system manages what happens when clicking in
a window and related functionality.  So, there is going to be variation on
different windowing systems.  I'm using Cinnamon, which mimics the Gnome 2
look-and-feel (but seems more robust); the floated windows stay visible when
parent is out of focus.  What system are you using?  I see a couple icons in
your screen capture that look like maybe Xfce or something.  It's really odd,
what you describe, the floated window hides when parent is not focused yet
remains visible when the parent is hidden.

Here is someone from back in 2007 that found the same behavior for kwin:

>From that person's description, it sounds like the floated windows go into
hidden mode.  (One can hide sub-panes via right-mouse-click and check/uncheck
next to the window name.)  Do the floated windows reappear when the V.E. is
brought back in focus?
