App Designer. As I mentioned in a previous post, Stateflow charts executed in MATLAB are very convenient to define the behavior of MATLAB apps. In such application, the MATLAB app itself only defines the graphical elements in the app, and maps apps callbacks to events in the Stateflow chart. Here is what the app looks like in design view: Use One Callback for Multiple App Designer Components. Sharing callbacks between components is useful when you want to offer multiple ways of doing something in your app. For example, you might want your app respond the same way when the user clicks a button or presses the Enter key in an edit field.

I need to continue debugging the code that I moved into App Designer by updating all plotting functions to specify a specific axes. I forgot I defined a bunch of interactivity callbacks (mouse-over, click and scroll wheel etc). Features covered in this code-along style video include: Specifying target axes with plotting commands

I want to be able to pass parameters or arguments into the callback function, but do not know how to do this or if it is even possible. Currently, this is how I create a callback function within the code view of App Designer. {test.ValueChangedFcn = createCallbackFcn(app,@testChange,true);} From there, I would create {function testChange(app,event) %%code end} I need to continue debugging the code that I moved into App Designer by updating all plotting functions to specify a specific axes.

Hi, Selecting 'No Callback' in the button properties "disconnects" the button and the callback but does not delete the callback. To delete the callback, select the Callbacks tab in the Code browser (to the left of the editor in code view) and select the callback you wish to delete. You can delete it with the delete key or right-click, delete.

In the code view, add a callback function that executes MATLAB ® commands whenever the user moves the slider. Right-click app.AmplitudeSlider in the Component Browser. Then select Callbacks > Add ValueChangedFcn callback in the context menu. App Designer creates a callback function and places the cursor in the body of that function.
