// A Canvas is an area mapped to a window directly under

// A ROOT session may have several canvases open at any given time.
//
// A Canvas may be subdivided into independent graphical areas: the PADs
// A canvas has a default pad which has the name of the canvas itself.
// An example of a Canvas layout is sketched in the picture below.

// Once objects have been drawn in a canvas, they can be edited/moved

// For example, to draw a new TText primitive, select the option Text,
// then click at the position where you want to draw the text. Type <CR>
