Enable/Disable uitabs in uitabgroup, with v2015b

Asked by Antoine Luijkx on 3 Oct 2015

In a GUI, is there a way to disable/enable a tab created by uitabgroup / uitab.
In a GUI I'm building, I would like to prevent the user from accessing some tabs at earlier stage of the process, and then grant access later when some operations are done in the GUI.
In following example:
fig=figure();
tabgroup=uitabgroup('Parent',fig);
tab1=uitab(tabgroup,'title','title1');
tab2=uitab(tabgroup,'title','title2');
I would like to disable tab2 (something like set(tab2,'Enable','off') would be nice).
It was possible with previous release (I tested with v2013a) using the following sequence:
jtabgroup=getappdata(handle(tabgroup),'JTabbedPane');
jtabgroup.setEnableAt(1,0);
... but I can't make it work using v2015b.
Thank you,
Antoine

To access the underlying Java object, use FindJObj.
Try replacing
jtabgroup=getappdata(handle(tabgroup),'JTabbedPane');
jtabgroup.setEnableAt(1,0);
With
jtabgroup=findjobj(tabgroup);
jtabgroup.setEnableAt(1,0);

Thank you, it works!
Just a typo: it's
jtabgroup.setEnabledAt(1,0);
instead of
jtabgroup.setEnableAt(1,0);
Thanks!
Hi,
I tried to apply your solution for my situation where I wanted to disable complete tabgroup. However when I use
jtabgroup=findjobj(tabgroup);
jtabgroup.setEnableAt(false); % also I tried turning enable off for
% for individual tabs using setEnabledAt(1,0)
I get an error saying
Undefined function 'setEnabled' for input arguments of type 'handle.handle'.
It would be extremely helpful if you can help me with this issue. Thanks in advance.
Not sure whether your question is still uptodate:
I am using Matlab 2014b.
handles = findjobj(tabgroup)
handles = findjobj(tabgroup)
returns four handles in my case.
If I use
handles(4).setEnabledAt(index,true)
it works.
Best regards Marius

A quick thought - how about using the SelectionChangedFcn callback of the uitabgroup object, to select another tab when one of the forbidden tabs is slected?

Thank you for proposal. That's indeed a workaround I have in mind. However, that's not fully satisfactory, as user can't see if a tab is enabled or not before clicking on it.
