Has anyone found a way to enable/disable tabs in App Designer?

105 views (last 30 days)
I am building a fairly simple GUI in I have tried implementations using findjobj, such as:
jtabgroup=findjobj(tabgrp);
jtabgroup.setEnabledAt(1,0);
but I am unsure if the app class can be read the same way (I'm very new to Java implementations). Any help would be much appreciated!

I found a possible way:
app.tabNameYouWantToDisable.Parent=[];
this will make the specific tab disappear from the GUI.
When you are done with the code execution you can reassign its parent:
app.tabNameYouWantToDisable.Parent=app.TabGroup;
I found this while using Matlab R2020a.

I don't believe that you can yet enable/disable tabs in MATLAB and this is something I have requested from them. Using findjobj with App Designer components is probably not going to be much use to you anyway as they are no longer Java Swing components like their uicontrol predecessors.

As of r2020a, there isn't an option to set the visibility or 'enable' property of a tab. However, you can control which tabs can be selected via the use of a SelectionChangedFcn.
Here's a demo that uses check boxes to determine whether a tab can be selected:

In my App I need to disable a tab's features (not the tab itself) while a process is occuring. My solution is to recursively find the children components of a given tab and set component.Enable = true or false. For graphics purposes I dont disable uilabels, etc (doesn't look great), so I exlude these. Edit: using MATLAB R2019a
function setEnableWithChildren(app, component, value)
% Recursively set enable status for all items
if isa(component, 'matlab.ui.control.Label') || isa(component, 'matlab.ui.control.Lamp')
return % Don't enable labels, etc.
end
if isprop(component, 'Enable')
if isa(component, 'matlab.ui.control.Table')
if value
component.Enable = 'on'; % Table uses on/off
else
component.Enable = 'off';
end
else
component.Enable = value;
end
end
if isprop(component, 'Children')
children = allchild(component);
else
children = [];
end
for child = reshape(children, 1, [])
app.setEnableWithChildren(child, value);
end
end

Use app.TabGroup.Visible='off';
