RTF File Showing and Printing

E-XD++ supports showing, instant editing, drawing, and WYSIWYG (What You See Is What You Get) printing for RTF documents. E-XD++ contains tens of operations for RTF document, such as reading RTF document, copying/pasting content in RTF document, Setting fonts/alignments for content in RTF document, etc, as shown below:

Steps:

1. Create font name and font size selection combobox at toolbar:

data.nComboID = IDC_COMBO_FONTNAME;
data.dwComboStyle = (UINT)CBS_DROPDOWN|WS_VSCROLL|CBS_HASSTRINGS|CBS_SORT|CBS_OWNERDRAWVARIABLE;
data.nDefaultWidth = 150;
data.nMinSize = 40;
data.nHeight = 250;
m_wndFontBar.ChangeToFontFaceComboButton(ID_FONT_FACENAME,data);

data.nComboID = IDC_COMBO_FONTSIZE;
data.dwComboStyle = (UINT)CBS_DROPDOWN|WS_VSCROLL;
data.nDefaultWidth = 40;
data.nMinSize = 40;
data.nHeight = 250;
m_wndFontBar.ChangeToComboButton(ID_FONT_TYPESIZE,data);

2. Change font name and size with rich text shape:

void CRichTextView::OnFontFaceChange()
{
	CMainFrame *pParent = STATIC_DOWNCAST(CMainFrame,AfxGetMainWnd());
	ASSERT_VALID(pParent);
	if(pParent->IsWindowVisible())
	{
		int nCur = pParent->pFontNameBox->GetCurSel();
		if(nCur != -1)
		{
			CString strFontName;
			pParent->pFontNameBox->GetLBText(nCur,strFontName);
			
			if (m_listSelectComp.GetCount() > 0)
			{
				CFODrawShape *pObj = GetCurrentSelectShape();
				ASSERT(pObj);
				
				if (pObj->IsKindOf(RUNTIME_CLASS(CFOPRichEditShape)))
				{
					CFOPRichEditShape *pRichEdit = static_cast<CFOPRichEditShape *>(pObj);
					ASSERT(pRichEdit);
					pRichEdit->SetCurrentFontName(strFontName);
				}
				else
				{
					GetCurrentModel()->ChangeShapesStringProp(&m_listSelectComp,strFontName,P_ID_FONT_FACENAME);
				}
				GetCurrentModel()->SetModifiedFlag();
				
				CFOWndDC dc(this);
				POSITION pos = m_listSelectComp.GetHeadPosition();
				while (pos != NULL) {
					((CFODrawShape*)m_listSelectComp.GetNext(pos))->AdjustTextBoxSize(&dc);
				}
				
				UpdateShapes(&m_listSelectComp);
			}
		}
	}
}

void CRichTextView::OnUpdateFontFacename(CCmdUI* pCmdUI) 
{
	// TODO: Add your command update UI handler code here
	pCmdUI->Enable(GetCurrentModel()->IsDesignMode());
	
	CString strFaceName = _T("");
	if (m_listSelectComp.GetCount() > 0)
	{

		}
		else
		{

		}
	}

	CMainFrame *pParent = STATIC_DOWNCAST(CMainFrame,AfxGetMainWnd());
	ASSERT_VALID(pParent);
	if (pParent->IsWindowVisible())
	{
		CString strFontName;
		pParent->pFontNameBox->GetWindowText(strFontName);

		if (strFontName == strFaceName) return;

		if (CB_ERR == pParent->pFontNameBox->SelectString(-1, strFaceName))
			TRACE(_T("the font name can't find."));
	}
}

{

	{

		{

			pParent->pFontSizeBox->GetLBText(nCur,strSize);

			if (m_listSelectComp.GetCount() > 0)
			{
				CFODrawShape *pObj = GetCurrentSelectShape();
				ASSERT(pObj);
				
				if (pObj->IsKindOf(RUNTIME_CLASS(CFOPRichEditShape)))
				{
					CFOPRichEditShape *pRichEdit = static_cast<CFOPRichEditShape *>(pObj);
					ASSERT(pRichEdit);
					pRichEdit->SetCurrentFontSize(atoi(strSize));
				}
				else
				{
					GetCurrentModel()->ChangeShapesIntProp(&m_listSelectComp,atoi(strSize),P_ID_FONT_POINTSIZE);
				}
				
				GetCurrentModel()->SetModifiedFlag();

				}

				UpdateShapes(&m_listSelectComp);
			}
		}
	}
}
