    • Constructor Detail

      • TreeTableCell

        public TreeTableCell​()
        Constructs a default TreeTableCell instance with a style class of 'tree-table-cell'.

    • Method Detail

      • getTableColumn

        public final TreeTableColumn<S,T> getTableColumn​()
        Gets the value of the property tableColumn.
        Property description:

      • getTreeTableView

        public final TreeTableView<S> getTreeTableView​()
        Gets the value of the property treeTableView.
        Property description:
        The TreeTableView associated with this TreeTableCell.

      • getTreeTableRow

        public final TreeTableRow<S> getTreeTableRow​()

      • startEdit

        public void startEdit​()
        Call this function to transition from a non-editing state into an editing state, if the cell is editable. If this cell is already in an editing state, it will stay in it.
        Overrides:
        startEdit in class Cell<T>

      • commitEdit

        public void commitEdit​(T newValue)
        Call this function when appropriate (based on the user interaction requirements of your cell editing user interface) to do two things:
        1. Fire the appropriate events back to the backing UI control (e.g. ListView). This will begin the process of pushing this edit back to the relevant data source / property (although it does not guarantee that this will be successful - that is dependent upon the specific edit commit handler being used). Refer to the UI control class javadoc for more detail.
        2. Begin the transition from an editing state into a non-editing state.

        In general there is no need to override this method in custom cell implementations - it should be sufficient to simply call this method when appropriate (e.g. when the user pressed the Enter key, you may do something like cell.commitEdit(converter.fromString(textField.getText()));

        Overrides:
        commitEdit in class Cell<T>
        Parameters:
        newValue - The value as input by the end user, which should be persisted in the relevant way given the data source underpinning the user interface and the install edit commit handler of the UI control.

      • cancelEdit

        public void cancelEdit​()
        Call this function to transition from an editing state into a non-editing state, without saving any user input.
        Overrides:
        cancelEdit in class Cell<T>

      • updateSelected

        public void updateSelected​(boolean selected)
        Updates whether this cell is in a selected state or not.
        Overrides:
        updateSelected in class Cell<T>
        Parameters:
        selected - whether or not to select this cell.

      • layoutChildren

        protected void layoutChildren​()
        Description copied from class: Cell
        Invoked during the layout pass to layout the children in this Parent. By default it will only set the size of managed, resizable content to their preferred sizes and does not do any node positioning.

        Subclasses should override this function to layout content as needed.

        Overrides:
        layoutChildren in class Cell<T>

      • updateTreeTableView

        public final void updateTreeTableView​(TreeTableView<S> tv)
        Updates the TreeTableView associated with this TreeTableCell. This is typically only done once when the TreeTableCell is first added to the TreeTableView. 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.
        Parameters:
        tv - the TreeTableView associated with this TreeTableCell

      • updateTreeTableRow

        public final void updateTreeTableRow​(TreeTableRow<S> treeTableRow)
        Updates the TreeTableRow 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.
        Parameters:
        treeTableRow - the TreeTableRow associated with this TreeTableCell

      • updateTreeTableColumn

        public final void updateTreeTableColumn​(TreeTableColumn<S,T> col)
        Updates the TreeTableColumn 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.
        Parameters:
        col - the TreeTableColumn associated with this TreeTableCell

      • createDefaultSkin

        protected Skin<?> createDefaultSkin​()
        Create a new instance of the default skin for this control. This is called to create a skin for the control if no skin is provided via CSS -fx-skin or set explicitly in a sub-class with setSkin(...).
        Overrides:
        createDefaultSkin in class Control
        Returns:
        new instance of default skin for this control. If null then the control will have no skin unless one is provided by css.

      • 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 Control
        Parameters:
        attribute - the requested attribute
        parameters - optional list of parameters
        Returns:
        the value for the requested attribute

        AccessibleAttribute

      • executeAccessibleAction

        public void executeAccessibleAction​(AccessibleAction action,
                                    Object... parameters)
        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 Control
        Parameters:
        action - the action to execute
        parameters - optional list of parameters

        AccessibleAction
