getNodeValue

public abstract String getNodeValue(TreeNode node)

Returns the string value for the provided node.

Parameters:

node - Determines the position in tree

Returns:

The

isContentAsTooltip

public boolean isContentAsTooltip()

Returns whether the content should also be visible as tooltip of the cell.

Returns:

whether the content should also be visible as tooltip

newCell

public Component newCell(MarkupContainer parent,

                         TreeNode node,
                         int level)

Description copied from interface: IColumn

This method is used to populate the cell for given node in case when IColumn.newCell(TreeNode, int) returned null.

Parameters:

parent - The parent to which the cell must be added. Can also be used to find the TreeTable instance (using parent.findParent(TreeTable.cass))

id - The component id

node - TreeNode for the cell

level - Convenience parameter that indicates how deep the node is in hierarchy

Returns:

The populated cell component

newCell

public IRenderable newCell(TreeNode node,
                           int level)

Description copied from interface: IColumn

Creates the IRenderable instance for given node. IRenderable can be used as lightweight alternative to regular Component for cells, that don't require user interaction (just display data).

If this method returns null, IColumn.newCell(MarkupContainer, String, TreeNode, int) is used to popuplate the cell.

Parameters:

node - TreeNode for the cell

level - Convenience parameter that indicates how deep the node is in hierarchy

Returns:

The cell renderer

setContentAsTooltip

public void setContentAsTooltip(boolean contentAsTooltip)

Sets whether the content should also be visible as tooltip (html title attribute) of the cell.

Parameters:

contentAsTooltip - whether the content should also be visible as tooltip
