89// A canvas named "edisplay" is created with a vertical size in pixels
90//
91// A QUICK Overview of the Event Display functions
92// ===============================================
93//
94// The event display can ve invoked by executing the macro "display.C"
95// A canvas like in the picture below will appear.
96//
97// On the left side of the canvas, the following buttons appear:
98// *Next* to move to the next event
99// *Previous* to move to the previous event
100
101// *Pick* Select this option to be able to point on a track with the
102// mouse. Once on the track, use the right button to select
103// an action. For example, select SetMarkerAttributes to
104// change the marker type/color/size for the track.
105// *Zoom* Select this option (default) if you want to zoom.
106// To zoom, simply select the selected area with the left button.
107// *UnZoom* To revert to the previous picture size.
108//
109// slider R On the left side, the vertical slider can be used to
110// set the default picture size.
111//
112// When you are in Zoom mode, you can click on the black part of the canvas
113// to select special options with the right mouse button.
114
115//
116// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
117// When you are on a track, select the menu item "InspectParticle"
118// to display the current particle attributes.
119//
120// You can activate the Root browser by selecting the Inspect menu
121// in the canvas tool bar menu. Then select "Start Browser"
122// This will open a new canvas with the browser. At this point, you may want
123// to display some histograms (from the Trees). Go to the "File" menu
124// of the browser and click on "New canvas".
125// In the browser, click on item "ROOT files" in the left pane.
126// Click on galice.root.
127// Click on TH
128// Click on TPC for example
129// Click on any variable (eg TPC.fX) to histogram the variable.
130//
131// If you are lost, you can click on HELP in any Root canvas or browser.
