◆ TRootEmbeddedCanvas() [2/2]

TRootEmbeddedCanvas::TRootEmbeddedCanvas ( const char *  name = nullptr,
const TGWindow p = nullptr,
UInt_t  w = 10,
UInt_t  h = 10,
UInt_t  options = kSunkenFrame | kDoubleBorder,
Pixel_t  back = GetDefaultFrameBackground() 
)

Create an TCanvas embedded in a TGFrame.

A pointer to the TCanvas can be obtained via the GetCanvas() member function. To embed a canvas derived from a TCanvas do the following: TRootEmbeddedCanvas *embedded = new TRootEmbeddedCanvas(0, p, w, h); [note name must be 0, not null string ""] Int_t wid = embedded->GetCanvasWindowId(); TMyCanvas *myc = new TMyCanvas("myname", 10, 10, wid); embedded->AdoptCanvas(myc); [ the MyCanvas is adopted by the embedded canvas and will be destroyed by it ]
