GCValues_t fValues graphics context values + mask
GContext_t fContext graphics context handle
TGGC and TGGCPool
Encapsulate a graphics context used in the low level graphics.
TGGCPool provides a pool of graphics contexts.
TGGC(GCValues_t *values, Bool_t)
Create a graphics context (only called via TGGCPool::GetGC()).
TGGC(GCValues_t *values)
Create a graphics context, registers GC in GCPool.
TGGC(const TGGC &g) : TObject(g), TRefCnt()
Copy a graphics context.
~TGGC()
Delete graphics context.
void UpdateValues(GCValues_t *values)
Update values + mask.
void SetAttributes(GCValues_t *values)
Set attributes as specified in the values structure.
void SetFunction(EGraphicsFunction v)
Set graphics context drawing function.
void SetPlaneMask(ULong_t v)
Set plane mask.
void SetForeground(ULong_t v)
Set foreground color.
void SetBackground(ULong_t v)
Set background color.
void SetLineWidth(Int_t v)
Set line width.
void SetLineStyle(Int_t v)
Set line style (kLineSolid, kLineOnOffDash, kLineDoubleDash).
void SetCapStyle(Int_t v)
Set cap style (kCapNotLast, kCapButt, kCapRound, kCapProjecting).
void SetJoinStyle(Int_t v)
Set line join style (kJoinMiter, kJoinRound, kJoinBevel).
void SetFillStyle(Int_t v)
Set fill style (kFillSolid, kFillTiled, kFillStippled,
kFillOpaeueStippled).
void SetFillRule(Int_t v)
Set fill rule (kEvenOddRule, kWindingRule).
void SetTile(Pixmap_t v)
Set tile pixmap for tiling operations.
void SetStipple(Pixmap_t v)
Set 1 plane pixmap for stippling.
void SetTileStipXOrigin(Int_t v)
X offset for tile or stipple operations.
void SetTileStipYOrigin(Int_t v)
Y offset for tile or stipple operations.
void SetFont(FontH_t v)
Set font.
void SetSubwindowMode(Int_t v)
Set sub window mode (kClipByChildren, kIncludeInferiors).
void SetGraphicsExposures(Bool_t v)
True if graphics exposure should be generated.
void SetClipXOrigin(Int_t v)
X origin for clipping.
void SetClipYOrigin(Int_t v)
Y origin for clipping.
void SetClipMask(Pixmap_t v)
Bitmap for clipping.
void SetDashOffset(Int_t v)
Patterned/dashed line offset.
void SetDashList(const char v[], Int_t len)
Set dash pattern. First use SetDashOffset() if not 0.
void SetArcMode(Int_t v)
Set arc mode (kArcChord, kArcPieSlice).
void Print(Option_t *) const
Print graphics contexts info.
TString GetMaskString() const
Returns GC mask as a string - used in SavePrimitive().
void SavePrimitive(ofstream &out, Option_t *option)
Save graphics context info as a C++ statement(s) on output stream out
