No, returning false from the text filter hook tells WASTE
that no filtering was performed, and the original text
should be processed as usual.

If you want to prevent WASTE from inserting the text,
you need to set the text handle size to zero, and
return true from your hook, like this:

  Boolean   MyTextFilter
	     (
            ComponentInstance	 inTextInputComponent,
		          Handle				         inFilterableText,
		          UInt32				         inModifiers,
		          UInt32				         inKeyCode,
		          WEReference			     inWE
      )
  {
      SetHandleSize(inFilterableText, 0);
      return true;
  }


HTH,

They want to turn it into a one-way flow that they have entirely
monetized. I look at the collective human mind as a kind of
ecosystem. They want to clear cut it. They want to go into the
rainforest of human thought and mow the thing down.
