[Octave-bug-tracker] [bug #53276] GUI: undocked panes cannot be moved, or resized along upper border

[Philip Nienhuis]

Follow-up Comment #29, bug #53276 (project octave):

Before the patch from comment #21 
* undocked panes could not be dragged around by dragging their title bar
* the undocked panes could be dragged by Alt-LMB anywhere on the pane, and 
* when the cursor was above the right, bottom and left borders and LL and LR
corners it turned into a resize cursor enabling the windows to be resized.
* when hovering the cursor above the top border, it could be resized as well

After the patch
* undocked panes can still be moved around with Alt-LMB
* resizing can ONLY be done when the cursor is in the lower right corner. The
cursor doesn't change anymore on L, B, R borders and LL corner.

I think the whole thing became deceiving as before the patch that led to this
bug report there were "regular" title bars on undocked panes that allowed easy
dragging, afterwards they disappeared or changed functionality while there was
no indication how to then move the panes nor how to resize them easily.
The confusing thing, at least for me, is that the main windows still has a
title bar that allows dragging, and (this is especially confusing and
inconsistent) docked panes can be dragged inside the main GUI window by their
-well, what is it? title bar?- but once undocked that doesn't work anymore.

In summary, I can say that everything works once you know how, but to me it
was pretty unclear. 
I'd rather have the way dragging and resizing worked before the multi-pane
variable editor was introduced.

BTW the patch from comment #21 didn't apply well (octave-dock-widget.cc hunk 5
and variable-editor.cc hunk 1) but going back rev. a26f8c97df21 ("hg -v update
-r a26f8c97df21") solved that.
