Class Description

                                                                      
 TGListView, TGLVContainer and TGLVEntry                              
                                                                      
 A list view is a widget that can contain a number of items           
 arranged in a grid or list. The items can be represented either      
 by a string or by an icon.                                           
                                                                      
 The TGListView is user callable. The other classes are service       
 classes of the list view.                                            
                                                                      
 A list view can generate the following events:                       
 kC_CONTAINER, kCT_SELCHANGED, total items, selected items.           
 kC_CONTAINER, kCT_ITEMCLICK, which button, location (y<<16|x).       
 kC_CONTAINER, kCT_ITEMDBLCLICK, which button, location (y<<16|x).    
                                                                      


TGLVContainer(const TGWindow *p, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGCompositeFrame(p, w, h, options, back)
 Create a list view container. This is the (large) frame that contains
 all the list items. It will be show through a TGViewPort (which is
 created by the TGCanvas derived TGListView).

~TGLVContainer()
 Delete list view container.

void SetViewMode(EListViewMode viewMode)
 Set list view mode for container.

void SetColumns(Int_t *cpos, Int_t *jmode)
 Set column information for list items.

TGDimension GetMaxItemSize() const
 Get maximum item size of all list view items in the container.

Bool_t HandleButton(Event_t *event)
 Handle mouse button event in container.

Bool_t HandleDoubleClick(Event_t *event)
 Handle double click mouse event.

Bool_t HandleMotion(Event_t *event)
 Handle mouse motion events.

void UnSelectAll()
 Unselect all items in the container.

void SelectAll()
 Select all items in the container.

void InvertSelection()
 Incert the selection, all selected items become unselected and
 vice versa.

void RemoveAll()
 Remove all items from the container.

void RemoveItem(TGLVEntry *item)
 Remove item from container.

void RemoveItemWithData(void *userData)
 Remove item with fUserData == userData from container.

const TGLVEntry* GetNextSelected(void **current)
 Return next selected item.
