a target object a selector to be sent an optional list of arguments for the message when to do the action (on mouse down, repeatedly while down, or on mouse up)
What is a selector?
You can actually set all of these using menu commands. To set the target, put the button over the desired target morph and then use the "set target" menu command on the button.
I can't find any "set target" menu command in the popup menu.
How do you tell a button to change a TextMorph's contents to "Hello World"?
Many thanks.
