Detailed Description

Dynamic list entry which links a histogram to a certain tree.

Method Process performs a single event TTree::Draw on this tree and directs the output to the histogram. String Parameters Varexp and Selection of Draw() are stored in the entry and are used for each Draw. This dynamic list entry does _not_ use the Go4 Conditions and event index scheme!

Member Function Documentation

TGo4DynamicEntryStatus * TGo4TreeHistogramEntry::CreateStatus ( ) [virtual]

Create a status object containing information such as the object names.
Can be sent to the Display to show the existing objects and their relations. Memento mechanism is _not_ provided here, since we would not change the object names afterwards.

Int_t TGo4TreeHistogramEntry::Process ( ) [virtual]

Process the dynamic entry.

Int_t TGo4TreeHistogramEntry::ProcessTree ( Int_t times )

Process the last "times" events in the tree.
