Problem with BottonDownFcn for a Pushbutton

Hi

I created a simple GUI like showing below.

What I would like to achieve is that when I click on the 'Start' button, it will 1) display 'hello' in the command window, and 2) the button will become invisible.

So firstly I wrote the code below to create an uicontrol which is a push button. Noticed that I set the 'ButtonDownFcn' of the push button to call another function 'clickObject'.

Then in the 'clickObject' function section I wrote the code below hoping that when I click on the button, 1) it will display 'hello' in the Command Window, and 2) the button will become invisible.

However, when I click on the button, nothing happens. The button is still there which I don't understand.

Can anyone help me please?

Just found the answer myself.

'ButtonDownFcn' is not suitable for 'pushbutton', rather I should use 'CallBack' instead.

So I have to change the line from 'ButtonDownFcn',@clickObject', to 'CallBack',@clickObject'.

Problem solved...
