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
}
Returns:
the
Component
that the renderer uses to draw the value
