Method Details

getTree

public Tree getTree()

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 ControlElement

setHeaderColor

public void setHeaderColor(Color color)

Specified by:

setHeaderColor in interface IHeaderCustomizationElement

setHeaderBackgroundColor

public void setHeaderBackgroundColor(Color color)

Specified by:

setHeaderBackgroundColor in interface IHeaderCustomizationElement

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.
