[Octave-bug-tracker] [bug #58544] Frame uicontrol cannot be deleted

[Rik]

Follow-up Comment #4, bug #58544 (project octave):

Whas is a "frame" uicontrol supposed to do?  Looking in the current code,
there is no implementation under Qt.  This means that Octave has a
representation of it as a graphics handle which can have a parent and
children, but there is no associated itme on a plot.  In that way, it is sort
of equivalent to an hggroup.

I went back to Octave 5.2 and I tried to see what behavior might have been
implemented, but it's not clear that it worked there either.


octave:1> hax = gca;
octave:2> hf = uicontrol ('style', 'frame');
octave:3> hb = uicontrol ('style', 'pushbutton', 'parent', hf)
error: uicontrol: invalid parent, the parent type must be: figure, uipanel,
uibuttongroup
error: called from
    __uiobject_split_args__ at line 57 column 7
    uicontrol at line 115 column 13
