TableViewSkin

public TableViewSkin(TableView<T> control)

Creates a new TableViewSkin 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

queryAccessibleAttribute

public 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 SkinBase<TableView<T>>

Parameters:

attribute - the requested attribute

parameters - optional list of parameters

Returns:

the value for the requested attribute

• AccessibleAttribute
• Node.queryAccessibleAttribute(AccessibleAttribute, 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<TableView<T>, TableRow<T>>

Returns:

the total number of items in this container
