[Xerte] default button

[Paul Swanson]

You can set up a key press interaction by adding an event response to
the interaction icon that contains your button. The eventName property
is onKeyDown and set the icon property to rootIcon. Then add a script
icon with something like the following:
 
keyPressed = Key.getCode();
 
if ((keyPressed == 13) || (keyPressed == 9)) { // Enter or Tab pressed

  // do whatever

}
 
The key numbers correlate to the ASCII chart of characters. A-Z is
65-90, a-z is 97-122, so for a lower-case y you would want to look for
121, capital Y should be 89. Lower-case n should be 110, and capital N
should be 78 (if I counted correctly).

	Thanks Julian, that explains. 
	Is it possible to set the focus to a certain button? And is it
possible to make a button react to a certain key pressed, like when I
have two buttons, yes and no, and want the user to be able to press Y or
N (besides making a third response to catch that)?

		It's built in accessibility. It will only respond to
keys whilst it has the focus. When you click elsewhere, the focus moves
away from the button and it doesn't respond to keypresses. All the
interaction responses can be controlled with the keyboard.

		Hi,

		 

		I've got a perpetual button ('Menu') in my Entry Frame.
For some reason, when I have used the button (just once), this button
will also get pressed when I hit the space bar. As I have not found yet
how to let a button react to key responses I was quite surprised...

		Does anyone know what caused this behaviour? It
disappeats after using a text entry response, but after hitting the
button again it reacts to the space bar again.

		 

		TIA

		 

		Elly
