Display information when ticking the checkbox in app designer.

hi, I'm having a little problem: how to click on the check box, the parameters like Size , Color.. will appear on the screen.

Please help me and thanks a lot

You must assign a ValueChangedFcn to the checkbox to react when users check or uncheck the box.

Within the ValueChangedFcn, you can turn off/on the Visible property of the Size and Color objects based on the Value returned within the callback function.

I wrote like that and not sure if it's correct. Can you help me go to the next part?

1. See this answer (Step 3) to learn how to add a ValueChangedFunction. This will add a callback function in your app's code. https://www.mathworks.com/matlabcentral/answers/503673-app-designer-create-a-discrete-slider#answer_414023
2. The Callback function will have 2 inputs. You can get the value of the checkbox from the first input using something like value=app.Checkbox.Value
3. If the Value is true, then you should turn on the visible properties of the objects you want to control. app.OBJECT.Visible=true, where OBJECT is the handle to whatever object you're targetting. If the Value is false, set visible to false.
