I have a balloon callout ISymbol and I want to get a polygon object so I can see if the user clicks it.
I am trying to use the function QueryBoundary http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#//001w00000372000000
The function has four arguments:
public void QueryBoundary ( int hDC, ITransformation displayTransform, IGeometry Geometry, //what can I put in here? IPolygon boundary );
One of my major hangups with the third argument is simply the fact that I am using this function to try to get the geometry... so what sense does it make to pass in the thing that I want? Also since the function is called like this :
thissymbol.QueryBoundary(screenDisplay.hDC, displayTransformation, thisGeometry, polygon);
Presumably it doesn't need the geometry of "thissymbol" since "thissymbol" is the caller.
