100// A canvas named "edisplay" is created with a vertical size in pixels
101//
102// A QUICK Overview of the Event Display functions
103// ===============================================
104//
105// The event display can ve invoked by executing the macro "display.C"
106// A canvas like in the picture below will appear.
107//
108// On the left side of the canvas, the following buttons appear:
109// *Next* to move to the next event
110// *Previous* to move to the previous event
111
112// *Pick* Select this option to be able to point on a track with the
113// mouse. Once on the track, use the right button to select
114// an action. For example, select SetMarkerAttributes to
115// change the marker type/color/size for the track.
116// *Zoom* Select this option (default) if you want to zoom.
117// To zoom, simply select the selected area with the left button.
118// *UnZoom* To revert to the previous picture size.
119//
120// slider R On the left side, the vertical slider can be used to
121// set the default picture size.
122//
123// When you are in Zoom mode, you can click on the black part of the canvas
124// to select special options with the right mouse button.
125
126//
127// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
128// When you are on a track, select the menu item "InspectParticle"
129// to display the current particle attributes.
130//
131// You can activate the Root browser by selecting the Inspect menu
132// in the canvas tool bar menu. Then select "Start Browser"
133// This will open a new canvas with the browser. At this point, you may want
134// to display some histograms (from the Trees). Go to the "File" menu
135// of the browser and click on "New canvas".
136// In the browser, click on item "ROOT files" in the left pane.
137// Click on galice.root.
138// Click on TH
139// Click on TPC for example
140// Click on any variable (eg TPC.fX) to histogram the variable.
141//
142// If you are lost, you can click on HELP in any Root canvas or browser.
