Property Details

id

public final StringProperty idProperty

The id of this PopupControl. This simple string identifier is useful for finding a specific Node within the scene graph. While the id of a Node should be unique within the scene graph, this uniqueness is not enforced. This is analogous to the "id" attribute on an HTML element (CSS ID Specification).

Default value:

null

See Also:

style

public final StringProperty styleProperty

A string representation of the CSS style associated with this specific PopupControl. This is analogous to the "style" attribute of an HTML element. Note that, like the HTML style attribute, this variable contains style properties and values and not the selector portion of a style rule.

A value of null is implicitly converted to an empty String.

Default value:

null

See Also:

skin

public final ObjectProperty<Skin<?>> skinProperty

Skin is responsible for rendering this PopupControl. From the perspective of the PopupControl, the Skin is a black box. It listens and responds to changes in state in a PopupControl.

There is a one-to-one relationship between a PopupControl and its Skin. Every Skin maintains a back reference to the PopupControl.

A skin may be null.

Specified by:

skinProperty in interface Skinnable

Returns:

the skin property for this Skinnable

Sentinel value which can be passed to a control's setMinWidth(), setMinHeight(), setMaxWidth() or setMaxHeight() methods to indicate that the preferred dimension should be used for that max and/or min constraint.

See Also:

USE_COMPUTED_SIZE

public static final double USE_COMPUTED_SIZE

See Also:

bridge

protected PopupControl.CSSBridge bridge

We need a special root node, except we can't replace the special root node already in the PopupControl. So we'll set our own special almost-root node that is a child of the root. This special root node is responsible for mapping the id, styleClass, and style defined on the PopupControl such that CSS will read the values from the PopupControl, and then apply CSS state to that special node. The node will then be able to pass cssSet calls along, such that any subclass of PopupControl will be able to use the Styleable properties and we'll be able to style it from CSS, in such a way that it participates and applies to the skin, exactly the way that normal Skin's work for normal Controls.
