MATLAB: How to enable a button after another button’s procedure has completed in App Designer

appdesignercallbackenableMATLAB

I am looking for an example that shows two things:

1. How to show an app is busy while computing something

2. How to enable a button after that computation is done

Best Answer

Attached is a simple app that accomplishes this as an example. The relevant code is in the first button's callback:

function computeFunction(app, event)
    set(app.NotComputingLabel, 'Text', 'Computing...')
      % your computation
      pause(3);
      set(app.NotComputingLabel, 'Text', 'Done Computing!')
      set(app.AccessibleAfterComputeButton, 'Enable', 'on')
  end

You can set the second button to be disabled by selecting it in the Design View and changing the "Enable" property on the right, in the "Button Properties" section.

MATLAB: How to disable Edit Field (Text) in App Designer

Here is an example to show how to control Editable about "Edit Field (Text)".

     function SwitchValueChanged(app, event)
              value = app.Switch.Value;
              if ( strcmpi(value,'On') )
                  app.VelocityEditField.Enable = 'On'
                  app.TemperatureEditField.Editable = 'On'
  %                 app.LoadEditField.Editable = 'On'
              else
                  app.VelocityEditField.Enable = 'Off'
                  *app.TemperatureEditField.Editable = 'Off'*
  %                 app.LoadEditField.Editable = 'Off'
              end
          end

This is the captured image to show the result of the above example. It is set so that editing is not possible at Temperature where Editable is off.

MATLAB: Appdesigner button group problem

Enabled property is not valid for Button Group but valid for Button. So, app.Button.Enable = 'off' will work.

%% Create UIFigure
app.UIFigure = uifigure;
app.UIFigure.Position = [100 100 640 480];
app.UIFigure.Name = 'UI Figure';
% Create ButtonGroup
app.ButtonGroup = uibuttongroup(app.UIFigure);
app.ButtonGroup.Title = 'Button Group';
app.ButtonGroup.Position = [282 115 123 106];
% Create Button
app.Button = uiradiobutton(app.ButtonGroup);
app.Button.Enable = 'off';
app.Button.Text = 'Button';
app.Button.Position = [11 60 58 22];
app.Button.Value = true;
% Create Button2
app.Button2 = uiradiobutton(app.ButtonGroup);
app.Button2.Enable = 'off';
app.Button2.Text = 'Button2';
app.Button2.Position = [11 38 65 22];
% Create Button3
app.Button3 = uiradiobutton(app.ButtonGroup);
app.Button3.Text = 'Button3';
app.Button3.Position = [11 16 65 22];
%% Disable all buttons 
app.Button.Enable = 'off';
app.Button2.Enable = 'off';
app.Button3.Enable = 'off';

Also, Button Group has Visible property, so you can hide button group by the following.

app.ButtonGroup.Visible = 'off';
