[REBOL] Re: Getting function keys to identify/bind to a field.

From: greggirwin::mindspring::com at: 13-Dec-2005 10:33

Hi Mike, MY> I would like to be able to press the "F4" key to prompt for a field. MY> Using this code it doesn't work as I would have imagined. 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. -- Gregg
