159// ===============================================
160//
161// The event display can ve invoked by executing the macro "display.C"
162// A canvas like in the picture below will appear.
163//
164// On the left side of the canvas, the following buttons appear:
165// *Next* to move to the next event
166// *Previous* to move to the previous event
167
168// *Pick* Select this option to be able to point on a track with the
169// mouse. Once on the track, use the right button to select
170// an action. For example, select SetMarkerAttributes to
171// change the marker type/color/size for the track.
172// *Zoom* Select this option (default) if you want to zoom.
173// To zoom, simply select the selected area with the left button.
174// *UnZoom* To revert to the previous picture size.
175//
176// slider R On the left side, the vertical slider can be used to
177// set the default picture size.
178//
179// When you are in Zoom mode, you can click on the black part of the canvas
180// to select special options with the right mouse button.
181
182//
183// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
184// When you are on a track, select the menu item "InspectParticle"
185// to display the current particle attributes.
186//
187// You can activate the Root browser by selecting the Inspect menu
188// in the canvas tool bar menu. Then select "Start Browser"
189// This will open a new canvas with the browser. At this point, you may want
190// to display some histograms (from the Trees). Go to the "File" menu
191// of the browser and click on "New canvas".
192// In the browser, click on item "ROOT files" in the left pane.
193// Click on galice.root.
194// Click on TH
195// Click on TPC for example
196// Click on any variable (eg TPC.fX) to histogram the variable.
197//
198// If you are lost, you can click on HELP in any Root canvas or browser.
