  • Constructor Details

    • 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 Details

    • 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.
