javax.swing.tree.TreeCellRenderer — clojure-interop/javax.swing 1.0.5

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.

(get-tree-cell-renderer-component this
                                  tree
                                  value
                                  selected
                                  expanded
                                  leaf
                                  row
                                  has-focus)

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 represents 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.

The TreeCellRenderer is also responsible for rendering the the cell representing the tree's current DnD drop location if it has one. If this renderer cares about rendering the DnD drop location, it should query the tree directly to see if the given row represents the drop location:

 JTree.DropLocation dropLocation = tree.getDropLocation();
 if (dropLocation != null
         && dropLocation.getChildIndex() == -1
         && tree.getRowForPath(dropLocation.getPath()) == row) {

     // this row represents the current drop location
     // so render it specially, perhaps with a different color
 }

tree - javax.swing.JTree value - java.lang.Object selected - boolean expanded - boolean leaf - boolean row - int has-focus - boolean

returns: the Component that the renderer uses to draw the value - java.awt.Component
