127// A QUICK Overview of the Event Display functions
128// ===============================================
129//
130// The event display can ve invoked by executing the macro "display.C"
131// A canvas like in the picture below will appear.
132//
133// On the left side of the canvas, the following buttons appear:
134// *Next* to move to the next event
135// *Previous* to move to the previous event
136
137// *Pick* Select this option to be able to point on a track with the
138// mouse. Once on the track, use the right button to select
139// an action. For example, select SetMarkerAttributes to
140// change the marker type/color/size for the track.
141// *Zoom* Select this option (default) if you want to zoom.
142// To zoom, simply select the selected area with the left button.
143// *UnZoom* To revert to the previous picture size.
144//
145// slider R On the left side, the vertical slider can be used to
146// set the default picture size.
147//
148// When you are in Zoom mode, you can click on the black part of the canvas
149// to select special options with the right mouse button.
150
151//
152// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
153// When you are on a track, select the menu item "InspectParticle"
154// to display the current particle attributes.
155//
156// You can activate the Root browser by selecting the Inspect menu
157// in the canvas tool bar menu. Then select "Start Browser"
158// This will open a new canvas with the browser. At this point, you may want
159// to display some histograms (from the Trees). Go to the "File" menu
160// of the browser and click on "New canvas".
161// In the browser, click on item "ROOT files" in the left pane.
162// Click on galice.root.
163// Click on TH
164// Click on TPC for example
165// Click on any variable (eg TPC.fX) to histogram the variable.
166//
167// If you are lost, you can click on HELP in any Root canvas or browser.
