static const enum TText:: kTextNDC
TText is the base class for several text objects.
See TAttText for a list of text attributes or fonts,
and also for a discussion on text speed and font quality.
By default, the text is drawn in the pad coordinates system.
One can draw in NDC coordinates [0,1] if the function SetNDC
is called for a TText object.
TText(): TNamed(), TAttText()
*-*-*-*-*-*-*-*-*-*-*Text default constructor*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-* ========================
TText(Double_t x, Double_t y, const char *text) : TNamed("",text), TAttText()
*-*-*-*-*-*-*-*-*-*-*Text normal constructor*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

TText(const TText &text) : TNamed(text), TAttText(text)
void Copy(TObject &obj) const
*-*-*-*-*-*-*-*-*-*-*Copy this text to text*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-* ======================
Int_t DistancetoPrimitive(Int_t px, Int_t py)
Compute distance from point px,py to a string.
The rectangle surrounding this string is evaluated.
If the point (px,py) is in the rectangle, the distance is set to zero.
TText* DrawText(Double_t x, Double_t y, const char *text)
*-*-*-*-*-*-*-*-*-*-*Draw this text with new coordinates*-*-*-*-*-*-*-*-*-*
*-* ===================================
TText* DrawTextNDC(Double_t x, Double_t y, const char *text)
*-*-*-*-*-*-*-*-*-*-*Draw this text with new coordinates in NDC*-*-*-*-*-*
*-* ==========================================
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
*-*-*-*-*-*-*-*-*-*-*Execute action corresponding to one event*-*-*-*
*-* =========================================
This member function must be implemented to realize the action
corresponding to the mouse click on the object in the window
void GetControlBox(Int_t x, Int_t y, Double_t theta,
Int_t CBoxX[4], Int_t CBoxY[4])
Return the text control box. The text position coordinates is (x,y) and
the text angle is theta. The control box coordinates are returned in CBoxX
and CBoxY.
void GetBoundingBox(UInt_t &w, UInt_t &h)
Return text size in pixels
void GetTextAscentDescent(UInt_t &a, UInt_t &d, const char *text) const
Return text ascent and descent for string text
in a return total text ascent
in d return text descent
void GetTextExtent(UInt_t &w, UInt_t &h, const char *text) const
Return text extent for string text
in w return total text width
in h return text height
void ls(Option_t *) const
*-*-*-*-*-*-*-*-*-*-*-*List this text with its attributes*-*-*-*-*-*-*-*-*
*-* ==================================
void Paint(Option_t *)
*-*-*-*-*-*-*-*-*-*-*Paint this text with its current attributes*-*-*-*-*-*-*
*-* ===========================================
void PaintControlBox(Int_t x, Int_t y, Double_t theta)
Paint the text control box. (x,y) are the coordinates where the control
box should be painted and theta is the angle of the box.
void PaintText(Double_t x, Double_t y, const char *text)
*-*-*-*-*-*-*-*-*-*-*Draw this text with new coordinates*-*-*-*-*-*-*-*-*-*
*-* ===================================
void PaintTextNDC(Double_t u, Double_t v, const char *text)
*-*-*-*-*-*-*-*-*-*-*Draw this text with new coordinates in NDC*-*-*-*-*-*-*
*-* ==========================================
void Print(Option_t *) const
*-*-*-*-*-*-*-*-*-*-*Dump this text with its attributes*-*-*-*-*-*-*-*-*-*
*-* ==================================
void SavePrimitive(ofstream &out, Option_t *)
Save primitive as a C++ statement(s) on output stream out
void SetNDC(Bool_t isNDC)
Set NDC mode on if isNDC = kTRUE, off otherwise
void Streamer(TBuffer &R__b)
Stream an object of class TText.
