Constructor Details

TreeTableViewSkin

public TreeTableViewSkin(TreeTableView<T> control)

Creates a new TreeTableViewSkin 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 - The control that this skin should be installed onto.

Method Details

dispose

public void dispose()

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.

Overridden to remove EventHandler.

Specified by:

dispose in interface Skin<T>

Overrides:

dispose in class TableViewSkinBase<T,TreeItem<T>,TreeTableView<T>,TreeTableRow<T>,TreeTableColumn<T,?>>

queryAccessibleAttribute

protected Object queryAccessibleAttribute(AccessibleAttribute attribute,
Object... parameters)

This method is called by the assistive technology to request the value for an attribute.

This method is commonly overridden by subclasses to implement attributes that are required for a specific role.
If a particular attribute is not handled, the superclass implementation must be called.

Overrides:

queryAccessibleAttribute in class TableViewSkinBase<T,TreeItem<T>,TreeTableView<T>,TreeTableRow<T>,TreeTableColumn<T,?>>

Parameters:

attribute - the requested attribute

parameters - optional list of parameters

Returns:

the value for the requested attribute

See Also:

AccessibleAttribute, Node.queryAccessibleAttribute(javafx.scene.AccessibleAttribute, java.lang.Object...)

executeAccessibleAction

protected void executeAccessibleAction(AccessibleAction action,
Object... parameters)

Description copied from class: SkinBase

This method is called by the assistive technology to request the action indicated by the argument should be executed.

This method is commonly overridden by subclasses to implement action that are required for a specific role.
If a particular action is not handled, the superclass implementation must be called.

Overrides:

executeAccessibleAction in class SkinBase<TreeTableView<T>>

Parameters:

action - the action to execute

parameters - optional list of parameters

See Also:

AccessibleAction, Node.executeAccessibleAction(javafx.scene.AccessibleAction, java.lang.Object...)

getItemCount

protected int getItemCount()

Returns the total number of items in this container, including those that are currently hidden because they are out of view.

Specified by:

getItemCount in class VirtualContainerBase<TreeTableView<T>,TreeTableRow<T>>

Returns:

the total number of items in this container

updateItemCount

protected void updateItemCount()

This method is called when it is possible that the item count has changed (i.e. scrolling has occurred, the control has resized, etc). This method should recalculate the item count and store that for future use by the VirtualContainerBase.getItemCount() method.

Overrides:

updateItemCount in class TableViewSkinBase<T,TreeItem<T>,TreeTableView<T>,TreeTableRow<T>,TreeTableColumn<T,?>>
