public abstract class Range
extends Widget

Base class for Widgets which present an adjustable quantity in some form of slider. The most obvious feature of this class is the ability to manage the "value" being shown by the Widget, but there are also facilities for exercising fine-grained control over the behaviour of the Widget when the user attempts to adjust the slider.

4.0.6

Method Detail

connect

public void connect(Range.ValueChanged handler)
Connect a Range.ValueChanged handler to this Range instance.

Since:
4.0.6

getInverted

public boolean getInverted()
Get whether or not the rate scale of this Range is inverted; see setInverted().

Since:
4.0.12

getValue

public double getValue()
Retrieve the value currently indicated by this Range instance.

Since:
4.0.6

setInverted

public void setInverted(boolean setting)
Inverts the way the value changes when moving the slider.

Ranges normally move from lower to higher values as the slider moves from top to bottom or left to right. Inverted ranges have higher values at the top or on the right rather than on the bottom or left.

Since:
4.0.12

setValue

public void setValue(double value)
Change the value showingin the Range. As you would expect, the Range.ValueChanged signal will be emitted if the new value is different from the present setting.

Since:
4.0.6
