16 // //
17 // The TGedMarkerPopup is a popup containing buttons to //
18 // select marker style. //
19 // //
20 // The TGedMarkerSelect widget is a button showing selected marker //
21 // and a little down arrow. When clicked on the arrow the //
22 // TGedMarkerPopup pops up. //
23 // //
24 // Selecting a marker in this widget will generate the event: //
25 // kC_MARKERSEL, kMAR_SELCHANGED, widget id, style. //
26 // //
27 // and the signal: //
28 // MarkerSelected(Style_t marker) //
