Getting function keys to identify/bind to a field.
[1/4] from: mike:yaunish:shaw:ca at: 12-Dec-2005 21:07
I would like to be able to press the "F4" key to prompt for a field.
Using this code it doesn't work as I would have imagined.
view layout [
f1: field keycode 'F4 [ print "field #1" ]
f2: field keycode 'F4 [ print "field #2" ]
]
field #1 is always grabbing the keycode action.
Any good ideas to work around this?

What do you mean exactly, "to prompt for a field" ?
What should happen when F4 is pressed ?
The reason the code below doesn't work is that the window key
handler just scans for the first face whose keycode matches the
key pressed.

Hi Mike,

If I understand you, the goal is to have a hot-key that can pop up a
prompt for any field. If so, you need to do it a different way. e.g.
view layout [key keycode 'F4 [print "Hello from F4"]]
The catch is that the general key handler doesn't know which face has
focus, so you need to track or dispatch on that yourself.
view layout [
f-1: field "I'm #1!"
f-2: field "I'm #2"
key keycode 'F4 [
switch system/view/focal-face reduce [
f-1 [print "field 1 has focus"]
f-2 [print "field 2 has focus"]
]
]
]
If you just set a custom word for the face and access that for your
prompt info, just keep in mind that system/view/focal-face will be
NONE if no face has focus.

Thanks Gregg,
This is exaclty what I was looking for. I am already custom naming
each field so I should be able to use their names to track who has
the focus.
