State machine callback bundles are a mechanism to hook actions to specific state transitions in the ReadoutGUI. The Event builder implements a callback bundle that, when registered will automatically do what is needed to manage the event builder without any further programmatic intervention from your ReadoutCallouts.tcl code.
The useEventBuilder command exported by the
evbrdocallouts package registers this callback
bundle with the Readout GUI's state machine.
EVBC::configure allows you to configure
the event builder options. All of the options described in the
EVBC::initialize
manpage are supported.
The startEVBSources proc is one that you should
write to start the event sources. It will be called as needed
by the callback bundle.
