Taking this a little further, if I were to create an array of push button
control objects, is there any way to programmatically assign different
actions to the buttons in the array?
There is, actually, though it's a bit obscure. The PushButton class
implements the ActionSource interface, which means that it has an
addActionNotificationReceiver method. This method takes, as a
parameter, any object that implements the actionNotificationReceiver
interface. So you can:
1. Create a class that has "actionNotificationReceiver" among its
interfaces. Such a class will therefore have a PerformAction method.
2. On your new pushbutton (let's call it pb), add an instance of your
class (let's call it thing) like so:
pb.addActionNotificationReceiver thing
3. There's no step three! Now, whenever somebody clicks the pb
button, thing's PerformAction method will be called.
This isn't necessarily the best way to solve your real problem
(another way would be to keep a dictionary that maps pushbuttons to
some sort of action, and simply look 'me' up in the button's Action
event and act accordingly), but it certainly is a nifty bit of RB
trivia, wouldn't you say?
Best,
- Joe
