The "Location" in LocationListener refers to URLs the browser is loading.
LocationListener has two methods:
void changed(LocationEvent event)
void changing(LocationEvent event)
- changed() is called after the displayed location changes
- changing() is called when a location change has been requested
LocationEvent has two fields:
boolean cancel
String location
You can set cancel to true in your changing() method to cancel the loading.
