## Class Description

     TGListBox, TGLBContainer, TGLBEntry and TGTextLBEntry

     A listbox is a box, possibly with scrollbar, containing entries.
     Currently entries are simple text strings (TGTextLBEntry).
     A TGListBox looks a lot like a TGCanvas. It has a TGViewPort
     containing a TGLBContainer which contains the entries and it also
     has a vertical scrollbar which becomes visible if there are more
     items than fit in the visible part of the container.

     The TGListBox is user callable. The other classes are service
     classes of the listbox.

     Selecting an item in the listbox will generate the event:
     kC_COMMAND, kCM_LISTBOX, listbox id, item id.

TGLineLBEntry(const TGWindow *p, Int_t id, const char *str, UInt_t w, Style_t style, UInt_t options, ULong_t back) : TGTextLBEntry(p, new TGString(str), id, GetDefaultGC()(), GetDefaultFontStruct(), options, back)

     Create the line style listbox entry

~TGLineLBEntry()

     Delete line style listbox entry.

void Update(TGLBEntry *e)

     Update line style listbox entry.

void SetLineStyle(Style_t linestyle)

     The linstyle corresponds to TPad line style

void SetLineWidth(Int_t width)

     Set or change line witdh in an entry.

void DoRedraw()

     Redraw line style listbox entry.
