javafx.scene.control.skin.VirtualContainerBase<C,I>

javafx.scene.control.skin.TableViewSkinBase<M,S,C,I,TC>

Type Parameters:

M - The type of the item stored in each row (for TableView, this is the type of the items list, and for TreeTableView, this is the type of the TreeItem).

S - The type of the item, as represented by the selection model (for TableView, this is, again, the type of the items list, and for TreeTableView, this is TreeItem typed to the same type as M).

C - The type of the virtualised control (e.g TableView, TreeTableView)

I - The type of cell used by this virtualised control (e.g. TableRow, TreeTableRow)

TC - The type of TableColumnBase used by this virtualised control (e.g. TableColumn, TreeTableColumn)

All Implemented Interfaces:

Skin<C>

Direct Known Subclasses:

TableViewSkin, TreeTableViewSkin

public abstract class TableViewSkinBase<M,S,C extends Control,I extends IndexedCell<M>,TC extends TableColumnBase<S,?>>
extends VirtualContainerBase<C,I>

TableViewSkinBase is the base skin class used by controls such as TableView and TreeTableView (the concrete classes are TableViewSkin and TreeTableViewSkin, respectively).

Constructor Detail

TableViewSkinBase

public TableViewSkinBase(C control)

Parameters:

control - the control

Method Detail

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.

Specified by:

dispose in interface Skin<M>

Overrides:

dispose in class SkinBase<C extends Control>

computePrefHeight

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

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.

Overrides:

computePrefHeight in class SkinBase<C extends Control>

Parameters:

width - the width that should be used if preferred height depends on it

topInset - the pixel snapped top inset

rightInset - the pixel snapped right inset

bottomInset - the pixel snapped bottom inset

leftInset - the pixel snapped left inset

Returns:

the calculated preferred height

computePrefWidth

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

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.

Overrides:

computePrefWidth in class SkinBase<C extends Control>

Parameters:

height - the height that should be used if preferred width depends on it

topInset - the pixel snapped top inset

rightInset - the pixel snapped right inset

bottomInset - the pixel snapped bottom inset

leftInset - the pixel snapped left inset

Returns:

the calculated preferred width

layoutChildren

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

Called during the layout pass of the scenegraph.

Overrides:

layoutChildren in class VirtualContainerBase<C extends Control,I extends IndexedCell<M>>

Parameters:

x - the x position

y - the y position

w - the width

h - the height

createTableHeaderRow

protected TableHeaderRow createTableHeaderRow()

Creates a new TableHeaderRow instance. By default this method should not be overridden, but in some circumstances it makes sense (e.g. testing, or when extreme customization is desired).

Returns:

A new TableHeaderRow instance.

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.

Specified by:

updateItemCount in class VirtualContainerBase<C extends Control,I extends IndexedCell<M>>

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 SkinBase<C extends Control>

Parameters:

attribute - the requested attribute

parameters - optional list of parameters

Returns:

the value for the requested attribute
