How to disable a panel in GUIDE ?

i have a panel with a no. of push buttons and other test fields, and i want to disable them till a radio button is selected; So, how can disable an entire panel without going for each component and disable them separately ??

I am using Matlab 2011a.

As of R2020b ButtonGroup and Panel both support Enable when the button group or panel is parented to a uifigure.

You could set() the entire uipanel to have Visible 'off'

But if you want the panel to be still visible, then

set(findall(PanelHandle, '-property', 'enable'), 'enable', 'off')

thank you for the answer.

but please tell how to select a particular panel among no. of panels ?

[Walter Roberson]

PanelHandle should be the handle of the panel you want to disable.

How are you distinguishing them in your code?

[Avi Pal]

now its working; i used the following

set(findall(handles.PanelHandle, '-property', 'enable'), 'enable', 'off')

since I was executing the line from the opening function of the figure.

Thanks a lot for your help ...

[Avi Pal]

just out of curiosity i am asking,

i couldn't find the enable property of a panel from the property inspector, but in the above line of code we are able to access it .. can u provide some explanation ?

[Walter Roberson]

There is no enable property of a uipanel.

findall() looks at all the children (recursively) of the given handle (the panel), and in the form given looks only for the children which have an 'enable' property; it returns that list of handles, and the set() sets the enable property of those handles to 'off'

[praveen chandaliya]

enable is not property of panel. after enable of if convert into on than this is not working

[Walter Roberson]

praveen chandaliya:

This code never tries to set the enable property of a panel. The findall() looks inside the panel to findall all contained graphics object that have an "enable" property, and it sets their "enable" status to 'off'

[praveen chandaliya]

Walter thank for clear my doubt. but i want to know after "enable" status go "off". if am required to "on" status of panel gui object than how to "on" its

[praveen chandaliya]

set(findall(handles.uipanel9, '-property', 'Visible'), 'Visible', 'on')

this code not working

set(findall(PanelHandle, '-property', 'enable'), 'enable', 'on')

not working either

[Walter Roberson]

It works in my tests. Which MATLAB version are you using? Are you getting any error message?

[Image Analyst]

Try

handles.uipanel9.Visible = 'on';  % Or 'off'
handles.uipanel9.Enable = 'on';  % Or 'off'

[praveen chandaliya]

matlab15a

[praveen chandaliya]

i am not getting error message

[Image Analyst]

OK, good. So I assume it's working now.

[Walter Roberson]

Please post a small example that demonstrates the problem.
