First, thanks for all the responses, but I should have been clearer. I do know the LC message hierarchy and I know the difference between pass, send, dispatch, etc.
What I was looking for is which messages, if intercepted, prevent a normally expected action in LiveCode. Richard's example of "CloseStackRequest" or my example of "rawKeyDown" fit this bill. "Normally" (and yes that can be subjective), you expect key presses to cause characters to appear or clicking in a closebox of a window to close the window. If the messages corresponding to those are trapped without passing the message, the event/action is not performed by the engine. This was an exercise in curiosity, not any particular coding problem. I was curious if anyone has compiled a list of those messages that the engine would perform a default action if the message is not trapped. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
