  • Constructor Details

    • 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 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 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>
    • 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:
      computePrefWidth in class SkinBase<ProgressIndicator>
      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 SkinBase<ProgressIndicator>
      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 SkinBase<ProgressIndicator>
      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 SkinBase<ProgressIndicator>
      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.
