139// ===============================================
140//
141// The event display can ve invoked by executing the macro "display.C"
142// A canvas like in the picture below will appear.
143//
144// On the left side of the canvas, the following buttons appear:
145// *Next* to move to the next event
146// *Previous* to move to the previous event
147
148// *Pick* Select this option to be able to point on a track with the
149// mouse. Once on the track, use the right button to select
150// an action. For example, select SetMarkerAttributes to
151// change the marker type/color/size for the track.
152// *Zoom* Select this option (default) if you want to zoom.
153// To zoom, simply select the selected area with the left button.
154// *UnZoom* To revert to the previous picture size.
155//
156// slider R On the left side, the vertical slider can be used to
157// set the default picture size.
158//
159// When you are in Zoom mode, you can click on the black part of the canvas
160// to select special options with the right mouse button.
161
162//
163// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
164// When you are on a track, select the menu item "InspectParticle"
165// to display the current particle attributes.
166//
167// You can activate the Root browser by selecting the Inspect menu
168// in the canvas tool bar menu. Then select "Start Browser"
169// This will open a new canvas with the browser. At this point, you may want
170// to display some histograms (from the Trees). Go to the "File" menu
171// of the browser and click on "New canvas".
172// In the browser, click on item "ROOT files" in the left pane.
173// Click on galice.root.
174// Click on TH
175// Click on TPC for example
176// Click on any variable (eg TPC.fX) to histogram the variable.
177//
178// If you are lost, you can click on HELP in any Root canvas or browser.
