First Steps: Interacting with Graphical Objects
Looking up ROOT class information. Creating graphical objects and interacting
with them.
In the lessons so far we have concentrated on developing user
objects
and looking to see how to interface them to the ROOT framework. Its
now time to look at some of the ROOT objects themselves. ROOT has a very
wide range of
classes
but we will concentrate on a few of those that beginners will find most useful
for analysis. Even so we will only look at a few of the most frequently used
features. As your confidence grows you should start to be able to look
directly at the ROOT class descriptions, a local copy of which you can
find
,
here.
You should look at
Reading ROOT Class Info
for beginner's tips.
As a first taste of the graphical interface to ROOT I cannot improve on
the ROOT tutorial
The Hello World example.
Bear in mind that links from there are not part of this Companion!
- ROOT includes a number of classes that have graphical representations.
- These representations can be dragged and clicked following standard GUI
conventions.
- Their attributes (colour, line width etc.) can be modified interactively using
the mouse.
