| 17. 86. 6. Add LocationListener to Browser |
|
|
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. |
