Constructor	Description
ColorPickerSkin(ColorPicker control)	Creates a new ColorPickerSkin instance, installing the necessary child nodes into the Control children list, as well as the necessary input mappings for handling key, mouse, etc events.

Method Summary

Modifier and Type	Method	Description
protected double	computePrefWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)	Calculates the preferred width of this SkinBase.
void	dispose()	Called by a Skinnable when the Skin is replaced on the Skinnable.
static List<CssMetaData<? extends Styleable,?>>	getClassCssMetaData()	Returns the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.
protected StringConverter<Color>	getConverter()	Subclasses are responsible for getting the converter.
List<CssMetaData<? extends Styleable,?>>	getCssMetaData()	This method should delegate to Node.getClassCssMetaData() so that a Node's CssMetaData can be accessed without the need for reflection.
Node	getDisplayNode()	This method should return a Node that will be positioned within the ComboBox 'button' area.
protected TextField	getEditor()	ColorPicker does not use a main text field, so this method has been overridden to return null.
protected Node	getPopupContent()	This method should return the Node that will be displayed when the user clicks on the ComboBox 'button' area.
protected void	layoutChildren(double x, double y, double w, double h)	Called during the layout pass of the scenegraph.

Constructor Detail

ColorPickerSkin

public ColorPickerSkin(ColorPicker control)

Creates a new ColorPickerSkin instance, installing the necessary child nodes into the Control children list, as well as the necessary input mappings for handling key, mouse, etc events.

Parameters:

control - The control that this skin should be installed onto.

Method Detail

dispose

public void dispose()

Called by a Skinnable when the Skin is replaced on the Skinnable. This method allows a Skin to implement any logic necessary to clean up itself after the Skin is no longer needed. It may be used to release native resources. The methods Skin.getSkinnable() and Skin.getNode() should return null following a call to dispose. Calling dispose twice has no effect.

Specified by:

dispose in interface Skin<ComboBoxBase<T>>

Overrides:

dispose in class SkinBase<ComboBoxBase<Color>>

computePrefWidth

protected double computePrefWidth(double height,
                                  double topInset,
                                  double rightInset,
                                  double bottomInset,
                                  double leftInset)

Calculates the preferred width of this SkinBase. The default implementation calculates this width as the width of the area occupied by its managed children when they are positioned at their current positions at their preferred widths.

Overrides:

computePrefWidth in class ComboBoxBaseSkin<Color>

Parameters:

height - the height that should be used if preferred width depends on it

topInset - the pixel snapped top inset

rightInset - the pixel snapped right inset

bottomInset - the pixel snapped bottom inset

leftInset - the pixel snapped left inset

Returns:

the calculated preferred width

getPopupContent

protected Node getPopupContent()

This method should return the Node that will be displayed when the user clicks on the ComboBox 'button' area.

Specified by:

getPopupContent in class ComboBoxPopupControl<Color>

Returns:

the Node that will be displayed when the user clicks on the ComboBox 'button' area

show

public void show()

This method will be called when the ComboBox popup should be displayed. It is up to specific skin implementations to determine how this is handled.

Overrides:

show in class ComboBoxPopupControl<Color>

getDisplayNode

public Node getDisplayNode()

This method should return a Node that will be positioned within the ComboBox 'button' area.

Specified by:

getDisplayNode in class ComboBoxBaseSkin<Color>

Returns:

the node that will be positioned within the ComboBox 'button' area

layoutChildren

protected void layoutChildren(double x,
                              double y,
                              double w,
                              double h)

Called during the layout pass of the scenegraph.

Overrides:

layoutChildren in class ComboBoxBaseSkin<Color>

Parameters:

x - the x position

y - the y position

w - the width

h - the height

getClassCssMetaData

public static List<CssMetaData<? extends Styleable,?>> getClassCssMetaData()

Returns the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.

Returns:

the CssMetaData associated with this class, which may include the CssMetaData of its superclasses

getCssMetaData

public List<CssMetaData<? extends Styleable,?>> getCssMetaData()

This method should delegate to Node.getClassCssMetaData() so that a Node's CssMetaData can be accessed without the need for reflection.

Overrides:

getCssMetaData in class SkinBase<ComboBoxBase<Color>>

Returns:

The CssMetaData associated with this node, which may include the CssMetaData of its superclasses.

getConverter

protected StringConverter<Color> getConverter()

Subclasses are responsible for getting the converter. This will be removed in FX 9 when the converter property is moved up to ComboBoxBase with JDK-8130354.

Specified by:

getConverter in class ComboBoxPopupControl<Color>

Returns:

the string converter

getEditor

protected TextField getEditor()

ColorPicker does not use a main text field, so this method has been overridden to return null.

Specified by:

getEditor in class ComboBoxPopupControl<Color>

Returns:

the editor
