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

[Dan Sebald]

Follow-up Comment #110, bug #53276 (project octave):

Not using the custom title bar is the core issue.  See the first half of this
post:

https://savannah.gnu.org/bugs/index.php?53276#comment21

The Qt documentation is indicating that one doesn't get full decorations if
the custom title bar is set.  The construct of setParent(0);
setTitleBarWidget(customtitle); setParent(0); is not documented as doing
anything, and in fact the rules that are defined in the documentation would
suggest the above should not have full decorations after the setParent(), if
anything.  set_title() uses the custom title bar.

For example, I couldn't have said in the KDE bug report
https://bugs.kde.org/show_bug.cgi?id=393076 that for Oxygen setParent(0);
setTitleBarWidget(customtitle); setParent(0); is not producing full
decorations therefore it should be fixed.  But I can say that for Oxygen
setTitleBarWidget(0); setParent(0); is not producing full decorations and
therefore it should be fixed.

The title color.  I added


                    "QDockWidget {\n"
                    "  %6\n"
                    "}\n"


to the cascading style sheet and it appears to fix the issue.  Before a new
changeset candidate, though, what do you mean by compactness?  Are you
referring to the title bar buttons?  I've mentioned before I feel those are
too close and difficult to select.  We can add padding to those buttons in the
CSS and spread those apart.
