Class Scale

Known Direct Subclasses:
HScale, VScale

public abstract class Scale
extends Range

A Scale is a slider control used to select a numeric value. To use it, you'll probably want to investigate the methods on its base class, Range, in addition to the methods for Scale itself. To set the value of a scale, you would normally use Range.setValue(double). To detect changes to the value, add RangeListener object to the widget.

The GtkScale widget is an abstract class, used only for deriving the subclasses HScale and VScale.

Method Details

getDrawValue

public boolean getDrawValue()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Returns whether the current value is displayed as a string next to the slider.

getEventListenerClass

public Class getEventListenerClass(String signal)
Overrides:
getEventListenerClass in interface Range

getEventType

public EventType getEventType(String signal)
Overrides:
getEventType in interface Range

getLayout

public Layout getLayout()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Gets the Layout used to display the scale.
Returns:
The Layout for this scale, or NULL if the getDrawValue() is FALSE.

getLayoutOffsetX

public int getLayoutOffsetX()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Obtains the X coordinate where the scale will draw the Layout representing the text in the scale.

If getDrawValue() is FALSE, the return value is undefined.


getLayoutOffsetY

public int getLayoutOffsetY()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Obtains the Y coordinate where the scale will draw the Layout representing the text in the scale.

If getDrawValue() is FALSE, the return value is undefined.


getType

public static Type getType()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Retrieve the runtime type used by the GLib library.
Overrides:
getType in interface Range

removeFormatListener

public void removeFormatListener()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Removes the format listener

setDigits

public void setDigits(int digits)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Sets the number of decimal places that are displayed in the value. Also causes the value of the adjustment to be rounded off to this number of digits, so the retrieved value matches the value the user saw.
Parameters:
digits - The number of decimal places to display, e.g. use 1 to display 1.0, 2 to display 1.00 etc.

setDrawValue

public void setDrawValue(boolean setting)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Specifies whether the current value is displayed as a string next to the slider.
Parameters:
setting - If true, the value is displayed.

setFormatListener

public void setFormatListener(ScaleListener listener)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Sets a listener to be used when a format-value request is called.

setValuePosition

public void setValuePosition(PositionType pos)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Sets the position in which the current value is displayed.
Parameters:
