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

Accepted Answer

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)

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.
