How to catch the event of applying color swatch to selected arts?

Hi,all
   I want to know when the event occurs(applying color swatch to selected arts). I used kAIDocSwatchesSelectionChangedNotifier to catch the event. But

many actions would trigger kAIDocSwatchesSelectionChangedNotifier, like moving or

resizing art.So, how can i realize this? Thanks.

I'm surprised about kAIDocSwatchesSelectionChangedNotifier -- its supposed to just indicate that the user has clicked on a different one in the Swatch panel. I suppose that's not a bad one to listen to and then see if there's any selected art, since that would probably indicate it was applied. The only other notifier that would help you is kAIArtPropertiesChangedNotifier, but that's incredibly general. There's nothing more specific than what you're using now I believe.

When the color of art is changed, these notifiers will be fired as follow:
1 kAIArtSelectionChangedNotifier
2 kAIDocSwatchesSelectionChangedNotifier
3 kAIArtPropertiesChangedNotifier
4 kAIAlignmentKeyArtChangedNotifier
5 kAIDocumentViewInvalidRectChangedNotifier

So,I did this:

if ( 0 == strcmp(message->type, kAIArtSelectionChangedNotifier) )
{
  notifyFlag |= 0x02;
  notifyFlag &= 3;
}
else if ( 0 == strcmp(message->type, kAIDocSwatchesSelectionChangedNotifier) )
{
  notifyFlag |= 0x04;   
  notifyFlag &= 7;
}
else if ( 0 == strcmp(message->type, kAIArtPropertiesChangedNotifier) )
{
  notifyFlag |= 0x08;   
  notifyFlag &= 15;
}
else if ( 0 == strcmp(message->type, kAIAlignmentKeyArtChangedNotifier) )
{
  notifyFlag |= 0x10;   
  notifyFlag &= 31;   
}
else if ( 0 == strcmp(message->type, kAIDocumentViewInvalidRectChangedNotifier) )
{
  notifyFlag |= 0x20;   
  notifyFlag &= 63;
  if (62 == notifyFlag)
   sADMBasic10->MessageAlert("U get it.");
}

But "U get it" is also showed when clicking other buttons on toolbar.
