Class IlpTreeCellRenderer

java.lang.Object
  ilog.cpl.tree.IlpTreeCellRenderer

All Implemented Interfaces:

TreeCellRenderer

public class IlpTreeCellRenderer
extends Object
implements TreeCellRenderer

Tree cell renderer dispatcher for an IlpTreeNode object. This tree cell renderer uses the following property:

• class indicates which JComponent or IlvGraphic to use to get the IlpGraphic that graphically represents the tree node.

When the class property is not defined, the rendering is done by a default renderer, that depends on the business object being represented.

Predefined business objects have a list of properties that can be used to customize their graphic representation in the Tree Component. Please refer to the User's Documentation for the list of properties of each predefined business object.

User-defined business objects are represented using a default renderer, that creates a Swing JLabel customized with the following properties:

• labelVisible
• label
• labelFont
• labelForeground
• labelBackground
• labelPosition
• labelSpacing
• iconVisible
• icon
• overlapIconVisible
• overlapIcon
• toolTipText
• focusBorderColor
• focusBorderWidth

The default tree cell renderer is also able to render the object selection and focus state according to the value of property selectionFocusMode. The possible values for this property are:

• IlpSelectionFocusMode.LABEL_SELECTION_FOCUS_MODE: displays a selection border around the label.
• IlpSelectionFocusMode.CELL_SELECTION_FOCUS_MODE: displays a selection border around the cell.

Since:

JTGO 3.0

Method Detail

getTreeCellRendererComponent

public Component getTreeCellRendererComponent(JTree tree,
                                              Object value,
                                              boolean selected,
                                              boolean expanded,
                                              boolean leaf,
                                              int row,
                                              boolean hasFocus)

Calculates the representation of a tree node. Using the associated tree style sheets, it gets the different graphic elements and returns a component based on them.

Specified by:

getTreeCellRendererComponent in interface TreeCellRenderer

Parameters:

tree - The tree in which the cell is drawn.

value - The TreeNode object that will be represented in the cell.

selected - true if the node is selected, false if the node is not selected.

expanded - true if the node is expanded, false if the node is collapsed.

leaf - true if the node is a leaf node, false if the node is an interior node between root and leaf.

row - The number of the line where the tree cell is, when the tree is seen as a list with one cell on each line.

hasFocus - true if the node has focus, false if the node does not have focus.

Returns:

The rendering component.
