class TToggle: public TNamed


This class defines toggling facility for both - object's method or
Assume that user provides an object with a two-state field , and
 methods to Get/Set value of this field. This object enables to switch
values via this method when the only thing you know about the field
is the name of the method (or method itself) which sets the field.
This facility is required in context Pop-Up menu, when the only
information about how to toggle a field is a name of methhod which
sets it.
This class may be also used for toggling an integer variable,
which may be important while building universal objects...
When user provides a "set-method" of name SetXXX this object tries
automaticaly find a matching "get-method" by lookin for a method
with name GetXXX, IsXXX or HasXXX for given object.

Function documentation

 TToggle default constructor. You have to initialize it before using
 by making a call to SetToggledVariable() or SetToggledObject().
void SetToggledVariable(Int_t& var)
 Initializes object for use with a variable - you pass it via reference
 so it will be modified by Toggle.
Bool_t GetState()
 Returns the state of Toggle according to its current value and
 fOnValue, returns true if they match.
void SetState(Bool_t state)
 Sets the value of toggle to fOnValue or fOffValue according to passed
void SetValue(Long_t val)
 Sets the value of toggle and modifies its state according to whether
 the value is equal to fOnValue.
void Toggle()
 Toggles the Values and State of this object and connected data!
void SetToggledObject(TObject* obj, TMethod* anymethod)
 Initializes it to toggle an object's datamember using this object's
Bool_t IsInitialized()
{return fInitialized;}
void SetOnValue(Long_t lon)
Long_t GetOnValue()
{return fOnValue;}
void SetOffValue(Long_t lof)
Long_t GetOffValue()
{return fOffValue;}
Int_t GetValue()
{return fValue;}
TMethodCall * GetGetter() const
{ return fGetter; }
TMethodCall * GetSetter() const
{ return fSetter; }
