public interface TreeCellRenderer

Defines the requirements for an object that displays a tree node. See How to Use Trees in The Java Tutorial for an example of implementing a tree cell renderer that displays custom icons.

Method Summary

getTreeCellRendererComponent(JTree tree, java.lang.Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) Sets the value of the current tree cell to value.

Method Detail

getTreeCellRendererComponent

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

Sets the value of the current tree cell to value. If selected is true, the cell will be drawn as if selected. If expanded is true the node is currently expanded and if leaf is true the node represets a leaf and if hasFocus is true the node currently has focus. tree is the JTree the receiver is being configured for. Returns the Component that the renderer uses to draw the value.

Returns:

the Component that the renderer uses to draw the value
