Direct Known Subclasses:

public class VFXLabeledCellSkin<T>
extends io.github.palexdev.mfxcore.controls.SkinBase<VFXCellBase<T>, CellBaseBehavior<T>>

Simple skin implementation to be used with any descendant of VFXCellBase.

This will display the data specified by the VFXCellBase.itemProperty() as a String in a Label. It's the only children of this skin, takes all the available space and has the following properties bound to the cell:

- the alignment property bound to VFXCellBase.alignmentProperty()

- the graphic property bound to VFXCellBase.graphicProperty().

The label's text will be updated on two occasions:

1) when the VFXCellBase.itemProperty() is invalidated

2) when an event of type VFXContainerEvent.UPDATE reaches the cell

You can modify addListeners() to change such behavior. For example, rather than using an InvalidationListener you could use a ChangeListener instead, add your own logic, etc. (useful when you want to optimize update performance).

(It's recommended to use SkinBase.listeners(When[]), SkinBase.events(WhenEvent[]) and in general When constructs. Simply because they make your life easier, also disposal would be automatic this way).

Last but not least, the label's text is updated by the update() method.

Constructor Details

VFXLabeledCellSkin

public VFXLabeledCellSkin(VFXCellBase<T> cell)

Method Details

addListeners

protected void addListeners()

Adds an InvalidationListener on the VFXCellBase.itemProperty() to call update() when it changes, and an EventHandler to support "manual" updates through events of type VFXContainerEvent.UPDATE.

(Uses When and WhenEvent constructs).

See Also:

• SkinBase.listeners(When[])
• SkinBase.events(WhenEvent[])

update

protected void update()

This is responsible for updating the label's text using the value specified by the VFXCellBase.itemProperty().

If the item is null sets the text to an empty string, otherwise calls toString() on it.

initBehavior

protected void initBehavior(CellBaseBehavior<T> behavior)

Overrides:

initBehavior in class io.github.palexdev.mfxcore.controls.SkinBase<VFXCellBase<T>, CellBaseBehavior<T>>

computePrefWidth

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

Overrides:

computePrefWidth in class SkinBase<VFXCellBase<T>>

layoutChildren

protected void layoutChildren(double x,
 double y,
 double w,
 double h)

Overrides:

layoutChildren in class SkinBase<VFXCellBase<T>>
