Constructor Detail

SpinnerSkinback to summary
public SpinnerSkin(Spinner<T> control)

Creates a new SpinnerSkin 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:Spinner<T>

The control that this skin should be installed onto.

protected double computeBaselineOffset(double topInset, double rightInset, double bottomInset, double leftInset)

Overrides javafx.scene.control.SkinBase.computeBaselineOffset.

Doc from javafx.scene.control.SkinBase.computeBaselineOffset.

Calculates the baseline offset based on the first managed child. If there is no such child, returns Node#getBaselineOffset().

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

Overrides javafx.scene.control.SkinBase.computeMaxHeight.

Doc from javafx.scene.control.SkinBase.computeMaxHeight.

Computes the maximum allowable height of the Skin, based on the provided width.

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

Overrides javafx.scene.control.SkinBase.computeMaxWidth.

Doc from javafx.scene.control.SkinBase.computeMaxWidth.

Computes the maximum allowable width of the Skin, based on the provided height.

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

Overrides javafx.scene.control.SkinBase.computePrefHeight.

Doc from javafx.scene.control.SkinBase.computePrefHeight.

Calculates the preferred height of this SkinBase. The default implementation calculates this height as the height of the area occupied by its managed children when they are positioned at their current positions at their preferred heights.

Annotations
@Override
computePrefWidthback to summary
protected double computePrefWidth(double height, double topInset, double rightInset, double bottomInset, double leftInset)

Overrides javafx.scene.control.SkinBase.computePrefWidth.

Doc from javafx.scene.control.SkinBase.computePrefWidth.

Calculates the preferred width of this SkinBase. The default implementation calculates this width as the width of the area occupied by its managed children when they are positioned at their current positions at their preferred widths.

Annotations
@Override
disposeback to summary
public void dispose()

Overrides javafx.scene.control.SkinBase.dispose.

Implements javafx.scene.control.Skin.dispose.

Doc from javafx.scene.control.SkinBase.dispose.

Called when a previously installed skin is about to be removed from its associated control. This allows the skin to do clean up, like removing listeners and bindings, and undo any changes to the control's properties. After this method completes, getSkinnable() and getNode() should return null.

Calling dispose() more than once has no effect.

Annotations
@Override
installback to summary
public void install()

Overrides default javafx.scene.control.Skin.install.

Doc from javafx.scene.control.Skin.install.

Called once when Skin is set. This method is called after the previous skin, if any, has been uninstalled via its dispose() method. The skin can now safely make changes to its associated control, like registering listeners, adding child nodes, and modifying properties and event handlers.

Application code must not call this method.

The default implementation of this method does nothing.
