Svg Icon Tool

[Brian Milby]

The silent update would allow that to happen in the hilitechanged handler.

I don’t know how you would implement a pre… message.  How would the widget know whether to proceed or not?  The two messages would fire almost simultaneously.  There also isn’t any way to tell the widget to cancel the highlight action, which would be needed.

A mouseDown message may work but would still need a way to cancel the highlight.  I think the silent change is the most seamless way to accomplish this task.

In general I think that normal mouse messages should be passed from widgets - even if they add specialized functionality with additional messages.  I don’t think they would solve this issue on their own though.

(I also did some work in this widget to add the nothing and multiple selections)
