TGToolTip(const TGWindow *p, const TGFrame *f, const char *text, Long_t delayms) : TGCompositeFrame(p, 10, 10, kHorizontalFrame | kRaisedFrame)
 Create a tool tip. P is the tool tips parent window (normally
 fClient->GetRoot(), f is the frame to which the tool tip is associated,
 text is the tool tip one-liner and delayms is the delay in ms before
 the tool tip is shown.

TGToolTip(const TGWindow *p, const TBox *box, const char *text, Long_t delayms) : TGCompositeFrame(p, 10, 10, kHorizontalFrame | kRaisedFrame)
 Create a tool tip. P is the tool tips parent window (normally
 fClient->GetRoot(), f is the frame to which the tool tip is associated,
 text is the tool tip one-liner and delayms is the delay in ms before
 the tool tip is shown.

TGToolTip(const TBox *box, const char *text,Long_t delayms) : TGCompositeFrame(gClient->GetRoot(), 10, 10, kHorizontalFrame | kRaisedFrame)
 Create a tool tip in the parent window gClient->GetRoot(),
 f is the frame to which the tool tip is associated,
 text is the tool tip one-liner and delayms is the delay in ms before
 the tool tip is shown.

~TGToolTip()
 Delete a tool tip object.

void DrawBorder()
 Draw border of tool tip window.

void Show(Int_t x, Int_t y)
 Show tool tip window.

void Hide()
 Hide tool tip window. Use this method to hide the tool tip in a client
 class.

void Reset()
 Reset tool tip popup delay timer. Use this method to activate tool tip
 in a client class.

void Reset(const TVirtualPad *parent)
 Reset tool tip popup delay timer. Use this method to activate tool tip
 in a client class. Use this method for graphics objects drawn in a
 TCanvas, also the tool tip must have been created with the ctor
 taking the TBox as argument.

Bool_t HandleTimer(TTimer *)
 If tool tip delay timer times out show tool tip window.
