I'm trying to learn and work with the gwt-earth project.. started with
the sort of hello earth program available at:
http://code.google.com/p/earth-api-samples/source/browse/#svn%2Ftrunk%2Fdemos%2Fgwt-earth%2Fsrc%2Fcom%2Fgoogle%253Fstate%253Dclosed
While the GEPlugin concept is fairly tricky - there is a GEWrapper
class that encapsulates a GEPlugin class, which in turn talks to a
class with native communication to the GEPlugin (GEPluginNative). In
that latter class i find native methods like:
public static native JavaScriptObject getFeatures(JavaScriptObject
ge)/*-{
return ge.getFeatures();
}-*/;
and i'm trying to add a new one that sets up zoom controllers (etc),
but can't seem to make it work. I've tried adding this:
public static native void setControlsVisible(JavaScriptObject ge)/*-{
ge.getNavigationControl().setControlType(ge.NAVIGATION_CONTROL_LARGE);
ge.getNavigationControl().setVisibility(ge.VISIBILITY_SHOW);
}-*/;
and then call it via GEPlugin class:
public void setControlsVisible()
{GEPluginNative.setControlsVisible(ge);}
but i end up with a runtime JS error ("this.d.b is null")..
Is it possible to add controls to the gwt-earth example program? what
am i missing?
Thanks for insight.
