TBrowser Class Reference

Using a TBrowser one can browse all ROOT objects.

It shows in a list on the left side of the window all browsable ROOT classes. Selecting one of the classes displays, in the icon-box on the right side, all objects in the class. Selecting one of the objects in the icon-box, will place all browsable objects in a new list and draws the contents of the selected class in the icon-box. And so on....

Member Function Documentation

void TBrowser::Add ( TObject obj,
const char *  name = 0,
Int_t  check = -1 
)

Add object with name to browser.

If name not set the objects GetName() is used. If check < 0 (default) no check box is drawn, if 0 then unchecked checkbox is added, if 1 checked checkbox is added.

Definition at line 261 of file TBrowser.cxx.

void TBrowser::Add ( void obj,
TClass cl,
const char *  name = 0,
Int_t  check = -1 
)

Add foreign object with name to browser.

'cl' is the type use to store the value of obj. So literally the following pseudo code should be correct:

`cl->GetName()` * ptr = (`cl->GetName()`*) obj;

and the value of obj is not necessarily the start of the object. If check < 0 (default) no check box is drawn, if 0 then unchecked checkbox is added, if 1 checked checkbox is added.

Definition at line 280 of file TBrowser.cxx.
