Method Detail

adjustValueback to summary
public void adjustValue(double pos)

Overrides javafx.scene.control.ScrollBar.adjustValue.

Doc from javafx.scene.control.ScrollBar.adjustValue.

Adjusts the value property by blockIncrement. The position is the fractional amount between the min and max. For example, it might be 50%. If #minProperty min were 0 and #maxProperty max were 100 and value were 25, then a position of .5 would indicate that we should increment value by blockIncrement. If value were 75, then a position of .5 would indicate that we should decrement value by blockIncrement.

Note

This function is intended to be used by experts, primarily by those implementing new Skins or Behaviors. It is not common for developers or designers to access this function directly.

Parameters
