Class TreeTablePosition<S,T>

java.lang.Object

javafx.scene.control.TablePositionBase<TreeTableColumn<S,T>>

javafx.scene.control.TreeTablePosition<S,T>

Type Parameters:

S - The type of the TreeItem instances contained within the TreeTableView.

T - The type of the items contained within the TreeTableColumn.

public class TreeTablePosition<S,T>
extends TablePositionBase<TreeTableColumn<S,T>>

This class is used to represent a single row/column/cell in a TreeTableView. This is used throughout the TreeTableView API to represent which rows/columns/cells are currently selected, focused, being edited, etc. Note that this class is immutable once it is created.

Because the TreeTableView can have different selection modes, the row and column properties in TablePosition can be 'disabled' to represent an entire row or column. This is done by setting the unrequired property to -1 or null.

Since:

JavaFX 8.0

Constructor Detail

TreeTablePosition

public TreeTablePosition(TreeTableView<S> treeTableView,
                         int row,
                         TreeTableColumn<S,T> tableColumn)

Constructs a TreeTablePosition instance to represent the given row/column position in the given TreeTableView instance. Both the TreeTableView and TreeTableColumn are referenced weakly in this class, so it is possible that they will be null when their respective getters are called.

Parameters:

treeTableView - The TreeTableView that this position is related to.

row - The row that this TreeTablePosition is representing.

tableColumn - The TreeTableColumn instance that this TreeTablePosition represents.

                  boolean doLookup)

Method Detail

getColumn

public int getColumn()

The column index that this TreeTablePosition represents in the TreeTableView. It is -1 if the TreeTableView or TreeTableColumn instances are null at the time the class is instantiated (i.e. it is computed at construction).

Specified by:

getColumn in class TablePositionBase<TreeTableColumn<S,T>>

Returns:

the column index that this TablePosition represents in the TableView

getTreeTableView

public final TreeTableView<S> getTreeTableView()

The TreeTableView that this TreeTablePosition is related to.

Returns:

the TreeTableView that this TreeTablePosition is related to

getTableColumn

public final TreeTableColumn<S,T> getTableColumn()

Description copied from class: TablePositionBase

The TableColumn that this TablePosition represents in the TableView.

Overrides:

getTableColumn in class TablePositionBase<TreeTableColumn<S,T>>

Returns:

the TableColumn that this TablePosition represents in the TableView

getTreeItem

public final TreeItem<S> getTreeItem()

Returns the TreeItem that backs the TablePositionBase.getRow() row}.

Returns:

the TreeItem that backs the TablePositionBase.getRow() row}
