19 /// Create an event display object.
20 /// A canvas named "edisplay" is created with a vertical size in pixels \n
22 /// A QUICK Overview of the Event Display functions \n
23 /// =============================================== \n
25 /// The event display can ve invoked by executing the macro "display.C" \n
26 /// A canvas like in the picture below will appear.
28 /// On the left side of the canvas, the following buttons appear:
29 /// - *Next* to move to the next event
30 /// - *Previous* to move to the previous event
31 /// - *Pick* Select this option to be able to point on a track with the
32 /// mouse. Once on the track, use the right button to select
33 /// an action. For example, select SetMarkerAttributes to
34 /// change the marker type/color/size for the track.
35 /// - *Zoom* Select this option (default) if you want to zoom.
36 /// To zoom, simply select the selected area with the left button.
37 /// - *UnZoom* To revert to the previous picture size.
39 /// - slider R On the left side, the vertical slider can be used to
40 /// set the default picture size.
42 /// When you are in Zoom mode, you can click on the black part of the canvas
43 /// to select special options with the right mouse button.
45 /// When you are in pick mode, you can "Inspect" the object pointed by the mouse.
46 /// When you are on a track, select the menu item "InspectParticle"
47 /// to display the current particle attributes.
49 /// You can activate the Root browser by selecting the Inspect menu
50 /// in the canvas tool bar menu. Then select "Start Browser"
51 /// This will open a new canvas with the browser. At this point, you may want
52 /// to display some histograms (from the Trees). Go to the "File" menu
53 /// of the browser and click on "New canvas".
54 /// In the browser, click on item "ROOT files" in the left pane.
55 /// Click on galice.root.
57 /// Click on TPC for example
58 /// Click on any variable (eg TPC.fX) to histogram the variable.
60 /// If you are lost, you can click on HELP in any Root canvas or browser.
