Constructor Detail

ProgressIndicatorSkin

public ProgressIndicatorSkin(ProgressIndicator control)

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

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<ProgressIndicator>

Overrides:

dispose in class SkinBase<ProgressIndicator>

layoutChildren

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

Called during the layout pass of the scenegraph.

Overrides:

layoutChildren in class SkinBase<ProgressIndicator>

Parameters:

x - the x position

y - the y position

w - the width

h - the height

computeMinWidth

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

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

Overrides:

computeMinWidth in class SkinBase<ProgressIndicator>

Parameters:

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

computeMinHeight

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

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

Overrides:

computeMinHeight in class SkinBase<ProgressIndicator>

Parameters:

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

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:
