This is an abstract base class for event displays.
Users need to define a class that derives from this class in order to make an event display. The only method that users must implement is the method AddAllCanvas(), where the user defines which tabs to use.
The user then needs to define how they what to update and plot histograms. The updating of histograms happens for each event. In online mode, the plotting of histograms only happens for each XX events; for offline mode the plotting happens for each event.
There are two ways that users can decide to update and plot histograms:
1) They can create histograms in their event display class and then fill the methods UpdateHistograms(TDataContainer) and PlotCanvas(TDataContainer). This histograms can then file in the canvases that are added using AddSingleCanvas(std::string name).
2) They can create classes that are derived from TCanvasHandleBase. The derived classes are then added using the method AddSingleCanvas(TCanvasHandleBase* handleClass).
There is no substantial difference between the two methods. The second method is mainly meant to allow the user to separate the methods into separate files for code cleaniness.
Examples of both these methods are available in examples/display_example.cxx
The actual ROOT GUI is encapsulated in a separate class TMainDisplayWindow. The TRootanaDisplay has an instance of this TMainDisplayWindow class. Users will be need to access the TMainDisplayWindow by calling
TRootanaDisplay::GetDisplayWindow()
in order to grab the particular canvas that we want plot on.
There is also the functionality to add sub-tab groups to a particular tab, so that you can have a set of tabs of tabs. To use this functionality you use the syntax
AddSingleCanvas(..., <tab name string>)
to add a new tab to the top level tab named 'tab name string'.
