I have put bits of the relevant code below. + m_EB_frame is a TGCompositeFrame
+ m_eCanvasErrorBanks is a TRootEmbeddedCanvas

 m_EB_frame->RemoveFrame(m_eCanvasErrorBanks);

 // make button frames
 if (m_EB_btnframes.empty()) {
   m_EB_btnframes.push_back
     (new TGHorizontalFrame(m_EB_frame, m_w, 33, kFixedWidth));    m_EB_btnframes.push_back
     (new TGHorizontalFrame(m_EB_frame, m_w, 33, kFixedWidth));    m_EB_btnframes.push_back
     (new TGHorizontalFrame(m_EB_frame, m_w, 33, kFixedWidth));    m_EB_btnframes.push_back
     (new TGHorizontalFrame(m_EB_frame, m_w, 33, kFixedWidth));  }

 // I add TGTextButtons to the TGHorizontalFrames here

 // add button frames and canvas to EB frame

 m_EB_frame->AddFrame(m_EB_btnframes[0],
   new TGLayoutHints(kLHintsCenterX,2,2,2,0));
 m_EB_frame->AddFrame(m_EB_btnframes[1],
   new TGLayoutHints(kLHintsCenterX,2,2,0,2));
 m_eCanvasErrorBanks->Resize(m_eCanvasErrorBanks->GetWidth(),
                             m_eCanvasErrorBanks->GetHeight() - 172);

 m_EB_frame->AddFrame(m_eCanvasErrorBanks);

 m_EB_frame->AddFrame(m_EB_btnframes[2],
   new TGLayoutHints(kLHintsCenterX,2,2,2,0));
 m_EB_frame->AddFrame(m_EB_btnframes[3],
   new TGLayoutHints(kLHintsCenterX,2,2,0,2));

Let me know if you need more info.

Thanks a lot.
