Class Description

                                                                      
 TGListTree and TGListTreeItem                                        
                                                                      
 A list tree is a widget that can contain a number of items           
 arranged in a tree structure. The items are represented by small     
 folder icons that can be either open or closed.                      
                                                                      
 The TGListTree is user callable. The TGListTreeItem is a service     
 class of the list tree.                                              
                                                                      
 A list tree can generate the following events:                       
 kC_LISTTREE, kCT_ITEMCLICK, which button, location (y<<16|x).        
 kC_LISTTREE, kCT_ITEMDBLCLICK, which button, location (y<<16|x).     
                                                                      

 Create a list tree widget.

 Create a list tree widget.

 Delete list tree widget.

 Highlight tree item.

 Higlight item children.

 Unselect all items.

 Handle button events in the list tree.

 Handle double click event in the list tree (only for kButton1).

 Handle expose event in the list tree.

 Handle mouse crossing event.

 Handle mouse motion event. Only used to set tool tip.

 The key press event handler converts a key press to some line editor
 action.

 Signal emitted when pointer is over entry.

 Emit ReturnPressed() signal.

 Emit Clicked() signal.

 Emit Clicked() signal.

 Emit DoubleClicked() signal.

 Emit DoubleClicked() signal.

 Move content to the top.

 Move content to the bottom.

 Move content one page up.

 Move content one page down.

 Move content one item-size up.

 Move content one item-size down.

 Move content to position of item. If item is 0, move to position
 of currently selected item.

 Invokes search dialog. Looks for item with the entered name.

 Redraw list tree.

 Redraw list tree.

 Draw list tree widget.

 Draw children of item in list tree.

 Draw list tree item.

 Draw name of list tree item.

 Draw node (little + in box).

 Set tool tip text associated with this item. The delay is in
 milliseconds (minimum 250). To remove tool tip call method with
 delayms = 0. To change delayms you first have to call this method
 with delayms=0.

 This function removes the specified item from the linked list.
 It does not do anything with the data contained in the item, though.

 Delete children of item from list.

 Insert child in list.

 Insert a list of ALREADY LINKED children into another list

 Search child item.

 Find item at postion findy.

 Add item to list tree. Returns new item.

 Add item to list tree. If item with same userData already exists
 don't add it. Returns new item.

 Rename item in list tree.

 Delete item from list tree.

 Open item in list tree (i.e. show child items).

 Close item in list tree (i.e. hide child items).

 Delete item with fUserData == ptr. Search tree downwards starting
 at item.

 Set tooltip text for this item. By default an item for which the
 userData is a pointer to an TObject the TObject::GetTitle() will
 be used to get the tip text.

 Delete children of item from list.

 Make newparent the new parent of item.

 Make newparent the new parent of the children of item.

 Sort items starting with item.

 Sort siblings of item.

 Sort children of item.

 Find sibling of item by name.

 Find sibling of item by userData.

 Find child of item by name.

 Find child of item by userData.

 Find item by pathname. Pathname is in the form of /xx/yy/zz. If zz
 in path /xx/yy is found it returns item, 0 otherwise.

 Highlight item.

 Un highlight items.

 Get pathname from item. Use depth to limit path name to last
 depth levels. By default depth is not limited.
