All Implemented Interfaces:
Skin<CheckBox>

public class CheckBoxSkin extends LabeledSkinBase<CheckBox,ButtonBehavior<CheckBox>>
Skin for tri state selection Control.

    • CheckBoxSkin

      public CheckBoxSkin(CheckBox checkbox)
  • Method Details

    • updateChildren

      protected void updateChildren()
      Description copied from class: LabeledSkinBase
      Updates the children managed by LabeledSkinBase, which can be the Labeled graphic and/or a Text node. Only those nodes which actually must be used are used. For example, with a ContentDisplay of GRAPHIC_ONLY the text node is not added, and with a ContentDisplay of TEXT_ONLY, the graphic is not added.
      Overrides:
      updateChildren in class LabeledSkinBase<CheckBox,ButtonBehavior<CheckBox>>
    • computeMinWidth

      protected double computeMinWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)
      Description copied from class: LabeledSkinBase
      Compute and return the minimum width of this Labeled. The minimum width is the smaller of the width of "..." and the width with the actual text. In this way, if the text width itself is smaller than the ellipsis then we should use that as the min width, otherwise the ellipsis needs to be the min width.

      We use the same calculation here regardless of whether we are talking about a single or multiline labeled. So a multiline labeled may find that the width of the "..." is as small as it will ever get.

      Overrides:
      computeMinWidth in class LabeledSkinBase<CheckBox,ButtonBehavior<CheckBox>>
      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)
      Description copied from class: SkinBase
      Computes the minimum allowable height of the Skin, based on the provided width.
      Overrides:
      computeMinHeight in class LabeledSkinBase<CheckBox,ButtonBehavior<CheckBox>>
      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)
      Description copied from class: SkinBase
      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 LabeledSkinBase<CheckBox,ButtonBehavior<CheckBox>>
      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)
      Description copied from class: SkinBase
      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 LabeledSkinBase<CheckBox,ButtonBehavior<CheckBox>>
      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
    • layoutChildren

      protected void layoutChildren(double x, double y, double w, double h)
      Description copied from class: LabeledSkinBase
      The Layout algorithm works like this: - Get the labeled w/h, graphic w/h, text w/h - Compute content w/h based on graphicVPos, graphicHPos, graphicTextGap, and graphic w/h and text w/h - (Note that the text content has been pre-truncated where necessary) - compute content x/y based on content w/h and labeled w/h and the labeled's hpos and vpos - position the graphic and text
      Overrides:
      layoutChildren in class LabeledSkinBase<CheckBox,ButtonBehavior<CheckBox>>
