I have been wondering how other people handle displaying different buttons at different times. For instance, let’s say that a user clicks on a button and once they do that you don’t want them to see that button again until they do sonething else. in the past I have handled this by simply changing the button’s ‘x’ or ‘y’ so that they are moved off the screen. One potential problem with this is that the button is still active in the tab order. What is the best practice for somthing like this?
