151// A QUICK Overview of the Event Display functions
152// ===============================================
153//
154// The event display can ve invoked by executing the macro "display.C"
155// A canvas like in the picture below will appear.
156//
157// On the left side of the canvas, the following buttons appear:
158// *Next* to move to the next event
159// *Previous* to move to the previous event
160
161// *Pick* Select this option to be able to point on a track with the
162// mouse. Once on the track, use the right button to select
163// an action. For example, select SetMarkerAttributes to
164// change the marker type/color/size for the track.
165// *Zoom* Select this option (default) if you want to zoom.
166// To zoom, simply select the selected area with the left button.
167// *UnZoom* To revert to the previous picture size.
168//
169// slider R On the left side, the vertical slider can be used to
170// set the default picture size.
171//
172// When you are in Zoom mode, you can click on the black part of the canvas
173// to select special options with the right mouse button.
174
175//
176// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
177// When you are on a track, select the menu item "InspectParticle"
178// to display the current particle attributes.
179//
180// You can activate the Root browser by selecting the Inspect menu
181// in the canvas tool bar menu. Then select "Start Browser"
182// This will open a new canvas with the browser. At this point, you may want
183// to display some histograms (from the Trees). Go to the "File" menu
184// of the browser and click on "New canvas".
185// In the browser, click on item "ROOT files" in the left pane.
186// Click on galice.root.
187// Click on TH
188// Click on TPC for example
189// Click on any variable (eg TPC.fX) to histogram the variable.
190//
191// If you are lost, you can click on HELP in any Root canvas or browser.
