ROOT 6.08/07 Reference Guide |
This class is automatically called by TFile::DrawMap.
It draws a canvas showing the internal structure of a ROOT file. Each key or basket in a file is shown with a fill area drawn at the byte position of the key/basket in the file. The Y axis of the canvas shows the number of Kbytes/Mbytes. The X axis shows the bytes between y(i) and y(i+1). A color corresponding to the class in the key/basket is automatically selected using the class unique identifier.
When moving the mouse in the canvas, the "Event Status" panels shows the object corresponding to the mouse position. if the object is a key, it shows the class and object name as well as the file directory name if the file has sub-directories.
if the object is a basket, it shows:
Special keys like the StreamerInfo record, the Keys List Record and the Free Blocks Record are also shown.
When clicking the right mouse button, a pop-up menu is shown with its title identifying the picked object and with the items:
The normal axis zoom functionality can be used to zoom or unzoom One can also use the TCanvas context menu SetCanvasSize to make a larger canvas and use the canvas scroll bars.
When the class is built, it is possible to identify a subset of the objects to be shown. For example, to view only the keys with names starting with "abc", set the argument keys to "abc*". The default is to view all the objects. The argument options can also be used (only one option currently) When the option "same" is given, the new picture is suprimposed. The option "same" is useful, eg: to draw all keys with names = "abc" in a first pass then all keys with names = "uv*" in a second pass, etc.
