MDITreeList

MDI with tree list view.

Custom draw dynamically generated CListCtrl, CTreeCtrl with dynamically resized font. Auto-resize CList Control. Non flicker Controls. Describes, how to dynamically change the font size of a dialog when it starts

Not flicker controls

CToolBarEx - Control bars that have a row of bitmapped buttons and optional separators. CListCtrlEx - Encapsulates the functionality of a "list view control," which displays a collection of items each consisting of an icon (from an image list) and a label. CHeaderCtrlEx - Provides the functionality of the Windows common header control.

Double Buffer Implementation

OnPaint event function:

	void CMyDraw::OnPaint()
	{
	   CPaintDC dc(this); // device context for painting
						   // TODO: Add your message handler code here
						   // Do not call CTreeCtrl::OnPaint() for painting messages

		CRect rect;
		CDC MenDC;//memory ID list. 
		CBitmap MemMap;
		GetClientRect(&rect);
		MenDC.CreateCompatibleDC(&dc);
		MemMap.CreateCompatibleBitmap(&dc, rect.Width(), rect.Height());
		MenDC.SelectObject(&MemMap);
		MenDC.FillSolidRect(&rect, dc.GetBkColor());

		// draw the graphic on the Memory DC 

		............

		//output  

		dc.BitBlt(0, 0, rect.Width(), rect.Height(), &MenDC, 0, 0, SRCCOPY);

		MenDC.DeleteDC();
		MemMap.DeleteObject();
	}

OnEraseBkgnd event

		BOOL CMyDraw::OnEraseBkgnd(CDC* pDC)
		{
		  return FALSE;
		}

Create MDI View from Dialog forms

How to create MDI View from Dialog forms.

Create standard Dialog form
Create Empty Document-View form
Add dialog instance to view
insert OnInitialUpdate action to message handlers.

Example:

		void CListFontView::OnInitialUpdate() 
		{
			CFormView::OnInitialUpdate();
			SetScrollSizes(MM_TEXT, CSize(0, 0)); // Hide Scrollbars in CFormView 
			m_ListCtrl.SubclassDlgItem(IDC_LIST, this);
			m_ListCtrl.SetNoOfColumns(3);
			m_ListCtrl.SetNoOfRows(2);
			m_ListCtrl.ShowScrollBar(SB_BOTH, FALSE);
			m_ListCtrl.OnInitialUpdate();
		}

Auto-resize CList Control

		void CListCtrlExt::OnSize(UINT nType, int cx, int cy)
		{
			CListCtrl::OnSize(nType, cx, cy);

			double currentSize = 0;

			CHeaderCtrl* pHeader = NULL;
			pHeader = GetHeaderCtrl();

			if (pHeader->m_hWnd != NULL) {

				for (int i = 0; i < pHeader->GetItemCount(); i++)
				{
					int nWidth = GetColumnWidth(i);
					currentSize += nWidth;
				}

				double m = cx / currentSize;

				for (int i = 0; i < pHeader->GetItemCount(); i++)
				{
					int nWidth = GetColumnWidth(i);
					double  d = nWidth *= m;
					DWORD w = d;
					SetColumnWidth(i, w);
				}
			}
		}

Design Components Library ( NDC )

Components for MFC WinForm help developers execute Design with modular and customizable UI components. These components enable a reliable development workflow to build beautiful and functional user experiences for C++ MFC Desktop application.

Custom MDI Frame color

CMainFrame :

        protected:
             CClientWnd  m_Client;

OnCreateClient action :

        BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
        {
            if (CMDIFrameWnd::OnCreateClient(lpcs, pContext))
            {
	            m_Client.SubclassWindow(m_hWndMDIClient);
	            return TRUE;
            }

            return CMDIFrameWnd::OnCreateClient(lpcs, pContext);
        }

OnClose action:

        void CMainFrame::OnClose(){
            .....
            m_Client.UnsubclassWindow();
            CMDIFrameWnd::OnClose();
        }

Custom Dialogs

Dialogs inform users about a task and can contain critical information, require decisions, or involve multiple tasks.

Using: change reference from CDialog to CDesignDialog CModalDialog to CModalDesignDialog

     include: CDesignDialog.h

Adding Icons to Menu Items

This is an easy way to add icons to the menu.

Create bitmap image.

If you using GIMP please export with:

		 Compatable Options:
		   - Do not write color space information
		 Advanced Options:  
		  - 24 bits R8 G8 B8

Add to .rc file:

	ID_APP_ABOUT   BITMAP   DISCARDABLE    "res\\bitmap1.bmp"

where ID_APP_ABOUT - your menu item ID

Add WM_INITMENUPOPUP handler in MainFrame class:

for example:

ON_WM_INITMENUPOPUP():

		void CMainFrame::OnInitMenuPopup(CMenu* pMenu, UINT nIndex, BOOL bSysMenu)
		{
			CMDIFrameWnd::OnInitMenuPopup(pMenu, nIndex, bSysMenu);

			if (bSysMenu)
			{
				pMenu = GetSystemMenu(FALSE);
			}
			MENUINFO mnfo;
			mnfo.cbSize = sizeof(mnfo);
			mnfo.fMask = MIM_STYLE;
			mnfo.dwStyle = MNS_CHECKORBMP | MNS_AUTODISMISS;
			::SetMenuInfo(pMenu->GetSafeHmenu(), &mnfo);

			MENUITEMINFO minfo;
			minfo.cbSize = sizeof(minfo);

			for (UINT pos = 0; pos < pMenu->GetMenuItemCount(); pos++)
			{
				minfo.fMask = MIIM_FTYPE | MIIM_ID ;
				pMenu->GetMenuItemInfo(pos, &minfo, TRUE);

				if (ID_APP_ABOUT == minfo.wID) {

					if (hBitmapAbout == NULL) {
						hBitmapAbout = (HBITMAP)::LoadBitmap(::AfxGetResourceHandle(),
							MAKEINTRESOURCE(ID_APP_ABOUT));
					}
					SetMenuItemBitmaps(pMenu->m_hMenu, pos, 
						  MF_BYPOSITION , hBitmapAbout, hBitmapAbout);
				}
			}
		}

Destructor:

		CMainFrame::~CMainFrame()
		{
			if (hBitmapAbout != NULL) {
				DeleteObject(hBitmapAbout);
			}
		}

Constructor:

		CMainFrame::CMainFrame()
		{
			// TODO: add member initialization code here
			NotLoginExit = false;
			hBitmapAbout = NULL;
		}

Measuring size text with DrawTextEx function

	   CFont* oldFont;
       CDC * cdc = GetDC();
       oldFont = cdc->SelectObject(font);

       auto format = DT_LEFT | DT_EDITCONTROL | DT_WORDBREAK | DT_CALCRECT;
       RECT cellRect ;

       DRAWTEXTPARAMS lpDTParams;
       lpDTParams.cbSize = sizeof(lpDTParams);
       lpDTParams.iLeftMargin = 1;
       lpDTParams.iRightMargin = 1;
       lpDTParams.iTabLength = 4;
       lpDTParams.uiLengthDrawn = 0;

       cellRect.right = colWidth;
       cellRect.bottom = 0;
       cellRect.top = 0;
       cellRect.left = 0;

       cdc->DrawTextEx(text, &cellRect, format, &lpDTParams);
       
       cdc->SelectObject(oldFont);
	   ReleaseDC(cdc);
