TreeTableRow (JavaFX 25)
Description: declaration: module: javafx.controls, package: javafx.scene.control, class: TreeTableRow

# Class TreeTableRow<T>

java.lang.Object
javafx.scene.Node
javafx.scene.Parent
javafx.scene.layout.Region
javafx.scene.control.Control
javafx.scene.control.Labeled
javafx.scene.control.Cell<T>
javafx.scene.control.IndexedCell<T>
javafx.scene.control.TreeTableRow<T>

Type Parameters:
  `T` - The type of the item contained within the Cell.

All Implemented Interfaces:
  `Styleable, EventTarget, Skinnable`

public class TreeTableRow<T> extends IndexedCell<T>

TreeTableRow is an `IndexedCell`, but rarely needs to be used by developers creating TreeTableView instances. The only time TreeTableRow is likely to be encountered at all by a developer is if they wish to create a custom `rowFactory` that replaces an entire row of a TreeTableView.

More often than not, it is actually easier for a developer to customize individual cells in a row, rather than the whole row itself. To do this, you can specify a custom `cellFactory` on each TreeTableColumn instance.

Since:
  JavaFX 8.0

    public final void updateTreeTableView(TreeTableView<T> treeTable)
    Updates the TreeTableView associated with this TreeTableCell.
    Parameters:
      `treeTable` - The new TreeTableView that should be associated with this TreeTableCell. Note: This function is intended to be used by experts, primarily by those implementing new Skins. It is not common for developers or designers to access this function directly.

    Updates the TreeItem associated with this TreeTableCell.
    Parameters:
      `treeItem` - The new TreeItem that should be associated with this TreeTableCell. Note: This function is intended to be used by experts, primarily by those implementing new Skins. It is not common for developers or designers to access this function directly.
