How to select a uibutton inside a uifgure by default - when the uifigure is opened.

The uibutton 'OK' needs to be in selcted condition when the uifigure opens, that is, the blue border on it.(as shown in the image)

This is required because if the user hits Enter, the OK button should execute.

How to program this ?
