Class Description

                                                                      
 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 iconbox on the right side, all   
 objects in the class. Selecting one of the objects in the iconbox,   
 will place all browsable objects in a new list and draws the         
 contents of the selected class in the iconbox. And so on....         
                                                                      
                       
                                                                      


TBrowser(const char *name, const char *title) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title. Width and height are by
 default set to 640x400 and (optionally) adjusted by the screen factor
 (depending on Rint.Canvas.UseScreenFactor to be true or false, default
 is true).

TBrowser(const char *name, const char *title, UInt_t width, UInt_t height) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, width and height.

TBrowser(const char *name, const char *title, Int_t x, Int_t y, UInt_t width, UInt_t height) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, position, width and height.

TBrowser(const char *name, TObject *obj, const char *title) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, width and height for TObject *obj.

TBrowser(const char *name, TObject *obj, const char *title, UInt_t width, UInt_t height) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, width and height for TObject *obj.

TBrowser(const char *name, TObject *obj, const char *title, Int_t x, Int_t y, UInt_t width, UInt_t height) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, width and height for TObject *obj.

TBrowser(const char *name, void *obj, TClass *cl, const char *objname, const char *title) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, width and height for TObject *obj.

TBrowser(const char *name, void *obj, TClass *cl, const char *objname, const char *title, UInt_t width, UInt_t height) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, width and height for TObject *obj.

TBrowser(const char *name,void *obj, TClass *cl, const char *objname, const char *title, Int_t x, Int_t y, UInt_t width, UInt_t height) : TNamed(name, title), fLastSelectedObject(0), fTimer(0), fContextMenu(0), fNeedRefresh(kFALSE)
 Create a new browser with a name, title, width and height for TObject *obj.

~TBrowser()
 Delete the browser.

void Add(TObject *obj, const char *name, Int_t check)
 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.

void Add(void *obj, TClass *cl, const char *name, Int_t check)
 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.

void AddCheckBox(TObject *obj, Bool_t check)
 Add checkbox for this item.

void CheckObjectItem(TObject *obj, Bool_t check)
 Change status of checkbox for this item.

void RemoveCheckBox(TObject *obj)
 Remove checkbox for this item.

void Create(TObject *obj)
 Create the browser, called by the ctors.

void ExecuteDefaultAction(TObject *obj)
 Execute default action for selected object (action is specified
 in the $HOME/.root.mimes or $ROOTSYS/etc/root.mimes file.

void RecursiveRemove(TObject *obj)
 Recursively remove obj from browser.

void Refresh()
 Refresh browser contents.

void SetSelected(TObject *clickedObject)
 Assign the last selected object.
