Adding a docking pane to your application Author: Kirk Stowell

Posted: November 16, 2007 Environment:Visual C++ MFC

The following is a tutorial on how to create an MDI application with Docking Pane using the Visual Studio 6.0 Application Wizard. The same technique can be used for later versions of Visual Studio . NET as well.

Create a simple MDI application using the MFC AppWizard:

? ?

From Visual Studio select ‘File’ then ‘New’ and select the ‘Projects’ tab.

Choose MFC Appwizard(exe) as your project type and enter ‘MDISample’ as the

project name.

? For the first step, make sure that \‘Finish’ button.

Add Empty Docking Pane ? Add the following line to your StdAfx.h file: Xtreme Toolkit Pro users:

#include // Xtreme Toolkit Pro components Xtreme DockingPane users:

#include // Xtreme DockingPane components

?

Add CXTPDockingPaneManager member to CMainFrame class.

?

// Attributes public:

CXTPDockingPaneManager m_paneManager;

?

Add string resources for the titles of the future panes

?

IDR_PANE_OPTIONS 61446 Options

PROPERTIES 61447 Properties ?

??

Add following to CMainFrame::OnCreate.

// Initialize the docking pane manager and set the // initial them for the docking panes. Do

// this only after all control bars objects have been // created and docked.

m_paneManager.InstallDockingPanes(this); m_paneManager.SetTheme(xtpPaneThemeOffice);

// Create docking panes.

CXTPDockingPane* pwndPane1 = m_paneManager.CreatePane( IDR_PANE_OPTIONS, CRect(0, 0,200, 120), dockLeftOf); CXTPDockingPane* pwndPane2 = m_paneManager.CreatePane( IDR_PANE_PROPERTIES, CRect(0, 0,200, 120), dockBottomOf, pwndPane1);

Attach CWnd derived class to the panes: ?? Add Cwnd derived class as member of CMainFrame.

// Attributes public:

CStatic m_wndOptions; CEdit m_wndProperties;

Add OnDockingPaneNotify handler.

         BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWnd)              //{{AFX_MSG_MAP(CMainFrame)              ON_WM_CREATE() 
             //}}AFX_MSG_MAP 
             ON_MESSAGE(XTPWM_DOCKINGPANE_NOTIFY,                  OnDockingPaneNotify)          END_MESSAGE_MAP() 
  
         LRESULT CMainFrame::OnDockingPaneNotify(WPARAM              wParam, LPARAM lParam) 
     { 
         if (wParam == XTP_DPN_SHOWWINDOW)          { 
             CXTPDockingPane* pPane = 
                     (CXTPDockingPane*)lParam;   
         if (!pPane->IsValid()) 
         { 
             switch (pPane->GetID())              { 
             case IDR_PANE_PROPERTIES:                  {                           
                     if ( 
                     m_wndProperties.GetSafeHwnd() == 0)                      { 
                         m_wndProperties.Create(WS_CHILD|                              ES_AUTOVSCROLL|ES_MULTILINE,                              CRect(0, 0, 0, 0), this, 0);                      } 
                     pPane->Attach(&m_wndProperties);                      break; 
                 } 
             case IDR_PANE_OPTIONS: 
                 {                           
                     if (m_wndOptions.GetSafeHwnd() == 0)                      { 
                         m_wndOptions.Create(_T(\                             WS_CHILD|WS_CLIPCHILDREN|                              WS_CLIPSIBLINGS|SS_CENTER,                              CRect(0, 0, 0, 0), this, 0);                      } 
                     pPane->Attach(&m_wndOptions);                      break;                  } 
             }              } 
             return TRUE;          } 
         return FALSE;      } 
 
Add image to pane. ?? Create Bitmap with icons for created panes 
 
?? 
Add to CMainFrame::OnCreate. 
  
     nt nIDIcons[] = {IDR_PANE_OPTIONS, IDR_PANE_PROPERTIES};      m_paneManager.SetIcons(IDB_BITMAP_ICONS, nIDIcons,          _countof(nIDIcons), RGB(0, 255, 0)); 
 
Add Save/Load State
