ShellElement

 CSSEngine engine)

Method Details

initialize

public void initialize()

Description copied from interface: CSSStylableElement

Method called after the CSSStylableElement was linked to the native widget. You can add UI listener into this method.

Specified by:

initialize in interface CSSStylableElement

Overrides:

initialize in class ControlElement

getParentNode

public Node getParentNode()

Specified by:

getParentNode in interface Node

Overrides:

getParentNode in class ControlElement

dispose

public void dispose()

Description copied from interface: CSSStylableElement

Method called when CSSEngine.dispose() is called. You can remove UI listener into this method.

Specified by:

dispose in interface CSSStylableElement

Overrides:

dispose in class ControlElement

isPseudoInstanceOf

public boolean isPseudoInstanceOf(String s)

Description copied from interface: CSSStylableElement

Return true if s is pseudo instance (ex :focus) and false otherwise.

Specified by:

isPseudoInstanceOf in interface CSSStylableElement

Overrides:

isPseudoInstanceOf in class ControlElement

internalGetAttribute

protected Supplier<String> internalGetAttribute(String attr)

Description copied from class: WidgetElement

The goal for WidgetElement.internalGetAttribute(String) is to share the code of WidgetElement.hasAttribute(String) and WidgetElement.getAttribute(String) and to keep the performance footprint for WidgetElement.hasAttribute(String) small. This shall be accomplished by:

• The method shall only be a lookup for a supplier, no actual computation shall be made.
• The result of the supplier must hold the requirements of the result of WidgetElement.getAttribute(String). Especially it must not return null.
• If the attribute isn't set on the widget, the method must return null.

Overrides:

internalGetAttribute in class WidgetElement

Parameters:

attr - the name of the attribute to look for.

Returns:

a supplier which will return the actual attribute value or null if the attribute isn't set for the widget.

reset

public void reset()

Description copied from class: WidgetElement

Called by the CSS engine upon a CSS theme switch. Implementations should restore the default value so that the new theme can be applied to the application without restart

Overrides:

reset in class CompositeElement
