Allow flying to a best-fit view of a feature programmatically (ala NetworkLink's flyToView)

[GoogleCodeExporter]

A FlyToView can be automatically created by a NetworkLink, that ensures all 
features are visible and centered on the screen, no matter what the browser 
size and configuration. When using fetchKml this view has to be included in the 
KML file or created manually, neither of which can account for the current 
browser size and configuration. Since the functionality is already there, it 
would be nice to be able to programmatically invoke the automatic FlyToView for 
a particular file, at any time, without the requirement of using a NetworkLink.

After we create a polygon or a polyline,it would be better,if we can obtain the 
bound of this gemetry,which can  be the best fit view.

Definitely a necessary animal for Folders, NetLinks, and Lines with LatLong 
stacks!

Additionally it would be nice to fly to a feature (best-fit) from within a 
playlist (gx:Tour)

hm, but there is a solution, i think :)
use this: http://code.google.com/p/earth-api-utility-library/wiki/
GEarthExtensionsReference

gex = new GEarthExtensions(ge);

and add this to Your fetchUserKmlFinished()
ge.getFeatures().appendChild(kmlObject);
gex.util.flyToObject(kmlObject, true);

While this workaround my help some users, I find GEX's functions for setting the
bounds view to be too approximate.  They are better/worse depending on how far 
out
you are zoomed.  An actual built in function might do a much better job.

of course, You are absolutely right
but.... as far as now, this is the only solution i know, and everyone needs to 
wait 
for the release :)
but if someone can't....

Pro tip... Don't try and test how many placemarks are in the feature before 
calling flyToObject as a performance optimization. You may trigger the bug in 
Issue 594.

Using the extensions really slows down the performance.
