144// A QUICK Overview of the Event Display functions
145// ===============================================
146//
147// The event display can ve invoked by executing the macro "display.C"
148// A canvas like in the picture below will appear.
149//
150// On the left side of the canvas, the following buttons appear:
151// *Next* to move to the next event
152// *Previous* to move to the previous event
153
154// *Pick* Select this option to be able to point on a track with the
155// mouse. Once on the track, use the right button to select
156// an action. For example, select SetMarkerAttributes to
157// change the marker type/color/size for the track.
158// *Zoom* Select this option (default) if you want to zoom.
159// To zoom, simply select the selected area with the left button.
160// *UnZoom* To revert to the previous picture size.
161//
162// slider R On the left side, the vertical slider can be used to
163// set the default picture size.
164//
165// When you are in Zoom mode, you can click on the black part of the canvas
166// to select special options with the right mouse button.
167
168//
169// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
170// When you are on a track, select the menu item "InspectParticle"
171// to display the current particle attributes.
172//
173// You can activate the Root browser by selecting the Inspect menu
174// in the canvas tool bar menu. Then select "Start Browser"
175// This will open a new canvas with the browser. At this point, you may want
176// to display some histograms (from the Trees). Go to the "File" menu
177// of the browser and click on "New canvas".
178// In the browser, click on item "ROOT files" in the left pane.
179// Click on galice.root.
180// Click on TH
181// Click on TPC for example
182// Click on any variable (eg TPC.fX) to histogram the variable.
183//
184// If you are lost, you can click on HELP in any Root canvas or browser.
