All Implemented Interfaces:

TraverseListener, Skin<MenuBar>

public class MenuBarSkin
extends BehaviorSkinBase<MenuBar,BehaviorBase<MenuBar>>
implements TraverseListener

The skin for the MenuBar. In essence it is a simple toolbar. For the time being there is no overflow behavior and we just hide nodes which fall outside the bounds.

Method Detail

setDefaultSystemMenuBar

public static void setDefaultSystemMenuBar(MenuBar menuBar)

setSpacing

public final void setSpacing(double value)

getSpacing

public final double getSpacing()

spacingProperty

public final DoubleProperty spacingProperty()

setContainerAlignment

public final void setContainerAlignment(Pos value)

getContainerAlignment

public final Pos getContainerAlignment()

containerAlignmentProperty

public final ObjectProperty<Pos> containerAlignmentProperty()

dispose

public void dispose()

Description copied from class: BehaviorSkinBase

Called by a Skinnable when the Skin is replaced on the Skinnable. This method allows a Skin to implement any logic necessary to clean up itself after the Skin is no longer needed. It may be used to release native resources. The methods Skin.getSkinnable() and Skin.getNode() should return null following a call to dispose. Calling dispose twice has no effect.

Specified by:

dispose in interface Skin<MenuBar>

Overrides:

dispose in class BehaviorSkinBase<MenuBar,BehaviorBase<MenuBar>>

onTraverse

public void onTraverse(Node node,
                       Bounds bounds)

Specified by:

onTraverse in interface TraverseListener

snappedTopInset

protected double snappedTopInset()

Overrides:

snappedTopInset in class SkinBase<MenuBar>

Returns:

Rounded up insets top

snappedBottomInset

protected double snappedBottomInset()

Description copied from class: SkinBase

Utility method to get the bottom inset which includes padding and border inset. Then snapped to whole pixels if getSkinnable().isSnapToPixel() is true.

Overrides:

snappedBottomInset in class SkinBase<MenuBar>

Returns:

Rounded up insets bottom

snappedLeftInset

protected double snappedLeftInset()

Description copied from class: SkinBase

Utility method to get the left inset which includes padding and border inset. Then snapped to whole pixels if getSkinnable().isSnapToPixel() is true.

Overrides:

snappedLeftInset in class SkinBase<MenuBar>

Returns:

Rounded up insets left

snappedRightInset

protected double snappedRightInset()

Description copied from class: SkinBase

Utility method to get the right inset which includes padding and border inset. Then snapped to whole pixels if getSkinnable().isSnapToPixel() is true.

Overrides:

Rounded up insets right

layoutChildren

protected void layoutChildren(double x,
                              double y,

                              double h)

Layout the menu bar. This is a simple horizontal layout like an hbox. Any menu items which don't fit into it will simply be made invisible.

Overrides:

Description copied from class: SkinBase

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

Overrides:
