Constructor Summary
LTreeNode(LTreeContent object)
          constructor: takes the content of the node ; the node will be displayed with a cell
 
Method Summary
 java.awt.Component add(java.awt.Component c)
          add a component or a node ; this is general and makes this tree structure powerful and flexible
 void addLTreeListener(LTreeListener listener)
          add a listener for this node
 java.awt.Component addSilent(java.awt.Component c)
          same as above but without expand
 void collapse()
          collapse this node and hide its sub nodes
 void delete()
          the node deletes itself if it is not the root
 void expand()
          expands this node and shows its sub nodes
 LTreeNode getParentNode()
          returns the parent node
 java.awt.Dimension getPreferredSize()
          returns the preferred size of this node, which has been computed with the sub nodes if the node is expanded
 void hasChanged()
          important function ; has to be called whenever a node is changed and needs to be updated/displayed
 boolean isExpanded()
          returns true if this node is expanded
 void mouseClicked(java.awt.event.MouseEvent e)
          useless methods of MouseListener
 void mouseEntered(java.awt.event.MouseEvent e)
           
 void mouseExited(java.awt.event.MouseEvent e)
           
 void mousePressed(java.awt.event.MouseEvent e)
          collapse or expands if one clicks on the triangle
 void mouseReleased(java.awt.event.MouseEvent e)
           
 void paintComponent(java.awt.Graphics g)
          paint this component (node) ; basically paints a triangle if necessary (if there is a content ; the cell is painted by the container function paintComponents(..)
 void removeAllNodes()
          removes all sub nodes attached to this node
 void removeNode(LTreeNode node)
          remove a sub node attached to this node
 void restoreViewport()
          restore the saved view port position
 void saveViewport()
          save the view port of the (maybe) parent viewport this is useful because JScrollPane looses track of the position of the view port
 void setPopup(javax.swing.JPopupMenu popup)
          set the popup of this node
 void unselect()
          unselect his node
