Constructor Detail

RadioButtonSkin

public RadioButtonSkin(RadioButton control)

Creates a new RadioButtonSkin instance, installing the necessary child nodes into the Control children list, as well as the necessary input mappings for handling key, mouse, etc events.

Parameters:

control - The control that this skin should be installed onto.

Method Detail

dispose

public void dispose()

updateChildren

protected void updateChildren()

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:

computeMinWidth

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

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.

computeMinHeight

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

computePrefWidth

                                  double topInset,
                                  double rightInset,
                                  double bottomInset,

                                   double rightInset,
                                   double bottomInset,
                                   double leftInset)

Overrides:

layoutChildren

protected void layoutChildren(double x,
                              double y,

                              double h)

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
