154// A QUICK Overview of the Event Display functions
155// ===============================================
156//
157// The event display can ve invoked by executing the macro "display.C"
158// A canvas like in the picture below will appear.
159//
160// On the left side of the canvas, the following buttons appear:
161// *Next* to move to the next event
162// *Previous* to move to the previous event
163
164// *Pick* Select this option to be able to point on a track with the
165// mouse. Once on the track, use the right button to select
166// an action. For example, select SetMarkerAttributes to
167// change the marker type/color/size for the track.
168// *Zoom* Select this option (default) if you want to zoom.
169// To zoom, simply select the selected area with the left button.
170// *UnZoom* To revert to the previous picture size.
171//
172// slider R On the left side, the vertical slider can be used to
173// set the default picture size.
174//
175// When you are in Zoom mode, you can click on the black part of the canvas
176// to select special options with the right mouse button.
177
178//
179// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
180// When you are on a track, select the menu item "InspectParticle"
181// to display the current particle attributes.
182//
183// You can activate the Root browser by selecting the Inspect menu
184// in the canvas tool bar menu. Then select "Start Browser"
185// This will open a new canvas with the browser. At this point, you may want
186// to display some histograms (from the Trees). Go to the "File" menu
187// of the browser and click on "New canvas".
188// In the browser, click on item "ROOT files" in the left pane.
189// Click on galice.root.
190// Click on TH
191// Click on TPC for example
192// Click on any variable (eg TPC.fX) to histogram the variable.
193//
194// If you are lost, you can click on HELP in any Root canvas or browser.
