ProgressIndicatorSkin
Creates a new ProgressIndicatorSkin instance, installing the necessary child nodes into the Controlchildren
list.- Parameters:
control
- The control that this skin should be installed onto.

Method Details
-
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 methodsSkin.getSkinnable()
andSkin.getNode()
should return null following a call to dispose. Calling dispose twice has no effect.- Specified by:
dispose
in interfaceSkin<ProgressIndicator>
- Overrides:
dispose
in classSkinBase<ProgressIndicator>
-
layoutChildren
protected void layoutChildren(double x, double y, double w, double h) Called during the layout pass of the scenegraph.- Overrides:
layoutChildren
in classSkinBase<ProgressIndicator>
-
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 classSkinBase<ProgressIndicator>
- Parameters:
height
- The height of the Skin, in case this value might dictate the minimum width.topInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- 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 classSkinBase<ProgressIndicator>
- Parameters:
width
- The width of the Skin, in case this value might dictate the minimum height.topInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- 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 thisSkinBase
. 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 classSkinBase<ProgressIndicator>
- Parameters:
height
- the height that should be used if preferred width depends on ittopInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- 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 thisSkinBase
. 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 classSkinBase<ProgressIndicator>
- Parameters:
width
- the width that should be used if preferred height depends on ittopInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- 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 classSkinBase<ProgressIndicator>
- Parameters:
height
- The height of the Skin, in case this value might dictate the maximum width.topInset
- the pixel snapped top insetrightInset
- the pixel snapped right insetbottomInset
- the pixel snapped bottom insetleftInset
- 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 classSkinBase<ProgressIndicator>
- Parameters:
width
- The width of the Skin, in case this value might dictate the maximum height.topInset
- the pixel snapped top insetrightInset
