Setting extent in JSlider model

Show all headers | View raw

How can I set how much a slider will change when the user hits the
PageUp of PageDown key, and when the user clicks in the slider's
trough?

The javadoc for JSlider's model (BoundedRangeModel) setExtent() method
states:

  When used with a slider, the extent determines how much the value
can "jump", for
  example when the user presses PgUp or PgDn.

However, setExtent() seems to have no effect. When I use the PgUp or
PgDn key, the value always changes 10% of the range regardless of the
value I request for extent.

As for clicking in the trough, metal L&F always seems to increment (or
decrement) the value by one, and for Nimbus it is the same as PgUp/
PgDn.
