Constructor Detail

ProgressBarSkin

public ProgressBarSkin(ProgressBar control)

Creates a new ProgressBarSkin instance, installing the necessary child nodes into the Control children list.

Parameters:

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

Method Detail

computeBaselineOffset

public double computeBaselineOffset(double topInset,
                                    double rightInset,
                                    double bottomInset,
                                    double leftInset)

Calculates the baseline offset based on the first managed child. If there is no such child, returns Node.getBaselineOffset().

Overrides:

computeBaselineOffset in class SkinBase<ProgressIndicator>

Parameters:

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:

baseline offset

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 ProgressIndicatorSkin

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

computePrefHeight

protected double computePrefHeight(double width,
                                   double topInset,
                                   double rightInset,
                                   double bottomInset,
                                   double leftInset)

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

Overrides:

computePrefHeight in class ProgressIndicatorSkin

Parameters:

width - the width that should be used if preferred height 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 height

computeMaxWidth

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

Computes the maximum allowable width of the Skin, based on the provided height.

Overrides:

computeMaxWidth in class ProgressIndicatorSkin

Parameters:

height - The height of the Skin, in case this value might dictate the maximum width.

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:

A double representing the maximum width of this Skin.

computeMaxHeight

protected double computeMaxHeight(double width,
                                  double topInset,
                                  double rightInset,
                                  double bottomInset,
                                  double leftInset)

Computes the maximum allowable height of the Skin, based on the provided width.

Overrides:

computeMaxHeight in class ProgressIndicatorSkin

Parameters:

width - The width of the Skin, in case this value might dictate the maximum height.

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:

A double representing the maximum height of this Skin.

layoutChildren

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

Called during the layout pass of the scenegraph.

Overrides:

layoutChildren in class ProgressIndicatorSkin

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 ProgressIndicatorSkin

Returns:

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