Class Adjustment

public class Adjustment extends GtkObject

Deprecated: This class is part of the java-gnome 2.x family of libraries, which, due to their inefficiency and complexity, are no longer being maintained and have been abandoned by the java-gnome project. This class may in the future have an equivalent in java-gnome 4.0, try looking for org.gnome.gtk.Adjustment. You should be aware that there is a considerably different API in the new library: the architecture is completely different and most notably internals are no longer exposed to public view.

This object stores geometry information, such as upper and lower bounds, step and page increments, and the size of a page. Other objects use an Adjustment object to store their internal dimension settings. It also is passed as an argument to specify geometry.

Constructor Detail

Adjustment

public Adjustment(Handle handle)

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.

Construct a new Adjustment from a handle to a native resource.

Adjustment

public Adjustment(double value, double lower, double upper, double stepIncrement, double pageIncrement, double pageSize)

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.

Constructs a new adjustment

Parameters: value The initial value. lower The minimum value. upper The maximum value. stepIncrement The step increment. pageIncrement The page increment. pageSize The page size.

Method Detail

addListener

public void addListener(AdjustmentListener 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.

Register an object to handle spin events.

clampPage

public void clampPage(double lower, double upper)

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.

Updates the GtkAdjustment value to ensure that the range between lower and upper is in the current page (ie between value and value + pageSize). If the range is larger than the page size, then only the start of it will be in the current page. A "changed" signal will be emitted if the value is changed.

getAdjustment

public static Adjustment getAdjustment(Handle handle)

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.

Internal static factory method to be used by Java-Gnome only.

getEventListenerClass

public Class getEventListenerClass(String signal)
Event Handling

getEventType

public EventType getEventType(String signal)

getLower

public double getLower()

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 minimum value of the adjustment

Returns: The minimum value of the adjustment.

getPageIncrement

public double getPageIncrement()

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 page increment of the adjustment.

Returns: The page increment of the adjustment.

getPageSize

public double getPageSize()

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 page size of the adjustment. Note that the page-size is irrelevant and should be set to zero if the adjustment is used for a simple scalar value, e.g. in a SpinButton.

Returns: The page size of the adjustment.

getStepIncrement

public double getStepIncrement()

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 step increment of the adjustment.

Returns: The step increment of the adjustment.

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.

getUpper

public double getUpper()

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 maximum value of the adjustment. Note that values will be restricted by upper - page-size if the page-size property is nonzero.

Returns: The maximum value of the adjustment.

getValue

public double getValue()

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 current value of the adjustment.

Returns: The current value of the adjustment.

handleChanged

public void handleChanged()

removeListener

public void removeListener(AdjustmentListener 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.

Removes a listener

setPageIncrement

public void setPageIncrement(double pageIncrement)

setPageSize

public void setPageSize(double pageSize)

setStepIncrement

public void setStepIncrement(double stepIncrement)

setUpper
