Re: [Gwt-openlayers-users] containsPoint method of Polygon class

[Philipp V. <phi...@go...>]

Hi there,

thanks for that. But there is a problem:
your suggested code returns true if var is 1. But if var is true it returns
false...

The containsPoint()-method returns 1, if the point is on an edge.
It returns true, if the point is inside and it returns false, if the point
is outside.

With my not existing JS skills the solution was the following:

public static native boolean containsPoint(JSObject p, JSObject self)/*-{
       var out = self.containsPoint(p);
       if (out) {return true}
       else if (out===1) {return true}
       else {return false}
    }-*/;

Cheers and thanks,
Philipp
