148// ===============================================
149//
150// The event display can ve invoked by executing the macro "display.C"
151// A canvas like in the picture below will appear.
152//
153// On the left side of the canvas, the following buttons appear:
154// *Next* to move to the next event
155// *Previous* to move to the previous event
156
157// *Pick* Select this option to be able to point on a track with the
158// mouse. Once on the track, use the right button to select
159// an action. For example, select SetMarkerAttributes to
160// change the marker type/color/size for the track.
161// *Zoom* Select this option (default) if you want to zoom.
162// To zoom, simply select the selected area with the left button.
163// *UnZoom* To revert to the previous picture size.
164//
165// slider R On the left side, the vertical slider can be used to
166// set the default picture size.
167//
168// When you are in Zoom mode, you can click on the black part of the canvas
169// to select special options with the right mouse button.
170
171//
172// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
173// When you are on a track, select the menu item "InspectParticle"
174// to display the current particle attributes.
175//
176// You can activate the Root browser by selecting the Inspect menu
177// in the canvas tool bar menu. Then select "Start Browser"
178// This will open a new canvas with the browser. At this point, you may want
179// to display some histograms (from the Trees). Go to the "File" menu
180// of the browser and click on "New canvas".
181// In the browser, click on item "ROOT files" in the left pane.
182// Click on galice.root.
183// Click on TH
184// Click on TPC for example
185// Click on any variable (eg TPC.fX) to histogram the variable.
186//
187// If you are lost, you can click on HELP in any Root canvas or browser.
