Requirements

Header: afxMDIFrameWndEx.h

CMDIFrameWndEx::ActiveItemRecalcLayout

Recalculates the layout of the active item.

void ActiveItemRecalcLayout();

CMDIFrameWndEx::AddPane

Registers a pane with the docking manager.

BOOL AddPane(
    CBasePane* pControlBar,
    BOOL bTail=TRUE);

Parameters

pControlBar
[in] Pointer to the pane to register.

bTail
[in] Specifies whether to add this pane to the end of the list.

Return value

Returns a non-zero value if the pane is registered successfully. Returns 0 if the pane is already registered with the docking manager.

Remarks

Each pane must be registered with the CDockingManager class before it can take a part in the docking layout. Use this method to notify the docking manager that you want to dock a specific pane. Once that pane is registered, the docking manager aligns it based on its alignment setting and position in the list of panes maintained by the docking manager.

CMDIFrameWndEx::AdjustClientArea

Reduces the client area to allow for a border.

virtual void AdjustClientArea();

CMDIFrameWndEx::AdjustDockingLayout

Recalculates the layout of all docked panes.

virtual void AdjustDockingLayout(HDWP hdwp=NULL);

Parameters

hdwp
[in] Identifies the multiple-window-position structure. You can obtain this value by calling BeginDeferWindowPos.

Remarks

Call this member function to recalculate the layout of all panes docked to the frame window.

CMDIFrameWndEx::AreMDITabs

Determines whether the MDI tabs feature or the MDI tabbed groups feature is enabled.

BOOL AreMDITabs(int* pnMDITabsType=NULL) const;

Parameters

pnMDITabsType
[out] A pointer to an integer variable that indicates which features are enabled:

  • 0: All features are disabled.
  • 1: MDI tabs is enabled.
  • 2: MDI tabbed groups is enabled.

Return value

Returns TRUE if MDI tabs or MDI tabbed groups is enabled.

Returns FALSE if none of the above features are enabled.

Remarks

Use this function to determine whether MDI tabs or MDI tabbed groups is enabled for the frame window. Use CMDIFrameWndEx::EnableMDITabs to enable or disable the MDI tabs feature.

Use CMDIFrameWndEx::EnableMDITabbedGroups to enable or disable the MDI tabbed groups feature.

CMDIFrameWndEx::CanConvertControlBarToMDIChild

Called by the framework to determine whether the frame window can convert docking panes to tabbed documents

virtual BOOL CanConvertControlBarToMDIChild();

Return Value

Returns TRUE if the frame window can convert docking panes to tabbed documents; otherwise returns FALSE.

Remarks

Override this method in a derived class and return TRUE to enable the conversion of docking panes to tabbed documents. Alternatively, you can set CMDIFrameWndEx::m_bCanConvertControlBarToMDIChild to TRUE.

CMDIFrameWndEx::ControlBarToTabbedDocument

Converts the specified docking pane to a tabbed document.

virtual CMDIChildWndEx* ControlBarToTabbedDocument(CDockablePane* pBar);

Parameters

pBar
A pointer to the docking pane to convert.

Return Value

Returns a pointer to the new MDI child window that contains the docking pane.

Remarks

This method converts a docking pane to a tabbed document. When you call this method, the framework creates a CMDIChildWndEx class object, removes the docking pane from the docking manager, and adds the docking pane to the new MDI child window. The MDI child window resizes the docking pane to cover the entire client area

CMDIFrameWndEx::CreateDocumentWindow

Creates a child document window.

virtual CMDIChildWndEx* CreateDocumentWindow(
    LPCTSTR lpcszDocName,
    CObject* pObj);

Parameters

lpcszDocName
[in] A text string that contains a document identifier. Typically, it's the full path of a document file.

pObj
[in] A pointer to a user-defined object. For example, a developer can create an application-specific data structure describing the document and telling how the document should be initialized at startup.

Return value

A pointer to CMDIChildWndEx.

Remarks

The framework calls this method when it loads the list of documents previously saved in the registry.

Override this method in order to create documents when they're being loaded from the registry.

Example

The following example shows how CreateDocumentWindow is used in the VisualStudioDemo Sample: MFC Visual Studio Application.

In this example, g_strStartViewName could be the name of a "virtual document" (for example, "Start Page") that isn't loaded from a disk file. Therefore we need special processing to handle that case.

CMainFrame::CMainFrame()
{
   CMFCPopupMenu::SetForceShadow(TRUE);
   m_bCanConvertControlBarToMDIChild = TRUE;
}

CMDIFrameWndEx::CreateNewWindow

Called by the framework to create a new window.

virtual CMDIChildWndEx* CreateNewWindow(
    LPCTSTR lpcszDocName,
    CObject* pObj);

Parameters

lpcszDocName
[in] The document name.

pObj
[in] Reserved for future use.

Return value

A pointer to the new window.

CMDIFrameWndEx::DockPane

Docks the specified pane to the frame window.

void DockPane(
    CBasePane* pBar,
    UINT nDockBarID=0,
    LPCRECT lpRect=NULL);

Parameters

pBar
[in] Pointer to the pane to dock.

nDockBarID
[in] Specifies which sides of the frame window to dock to.

lpRect
[in] Not used.

Remarks

This method docks the specified pane to one of the sides of the frame window that was specified when CBasePane::EnableDocking and CMDIFrameWndEx::EnableDocking were called.

Example

The following example demonstrates the use of the DockPane method. This code snippet comes from the VisualStudioDemo Sample: MFC Visual Studio Application.

DockPane(&m_wndMenuBar);
DockPane(&m_wndToolBar);
DockPane(&m_wndPropertiesBar);

DockPane(&m_wndToolbarBuild);

CMDIFrameWndEx::DockPaneLeftOf

Docks one pane to the left of another pane.

BOOL DockPaneLeftOf(
    CPane* pBar,
    CPane* pLeftOf);

Parameters

pBar
[in] A pointer to the docking pane.

pLeftOf
[in] A pointer to the pane that serves as the dock site.

Return value

Returns TRUE if the operation is successful. Otherwise returns FALSE.

Remarks

Call this method to dock several pane objects in a predefined order. This method docks the pane specified by pBar to the left of the pane specified by pLeftOf.

Example

The following example shows how the DockPaneLeftOf method is used in the VisualStudioDemo Sample: MFC Visual Studio Application.

DockPane(&m_wndToolbarBuild);
DockPaneLeftOf(&m_wndToolbarEdit, &m_wndToolbarBuild);

CMDIFrameWndEx::EnableAutoHidePanes

Enables auto-hide mode for panes when they're docked at the specified sides of the main frame window.

BOOL EnableAutoHidePanes(DWORD dwDockStyle);

Parameters

dwDockStyle
[in] Specifies the sides of the main frame window that will be enabled. Use one or more of the following flags.

  • CBRS_ALIGN_LEFT
  • CBRS_ALIGN_RIGHT
  • CBRS_ALIGN_TOP
  • CBRS_ALIGN_BOTTOM

Return value

Call this function to enable auto-hide mode for panes when they're docked at the specified sides of the main frame window.

Example

The following example shows how the EnableAutoHidePanes method is used in the VisualStudioDemo Sample: MFC Visual Studio Application.

EnableAutoHidePanes(CBRS_ALIGN_ANY);

Remarks

CMDIFrameWndEx::EnableDocking

Enables docking of the panes that belong to the MDI frame window.

BOOL EnableDocking(DWORD dwDockStyle);

Parameters

dwDockStyle
[in] Specifies the docking style that you want to apply.

Return value

Remarks

Call this function to enable docking of panes that belong to the CMDIFrameWndEx object.

Example

The following example shows how the EnableDocking method is used in the VisualStudioDemo Sample: MFC Visual Studio Application.

EnableDocking(CBRS_ALIGN_ANY);

CMDIFrameWndEx::EnableFullScreenMainMenu

Shows or hides the main menu in full-screen mode.

void EnableFullScreenMainMenu(BOOL bEnableMenu);

Parameters

bEnableMenu
[in] TRUE to show the main menu in full-screen mode, or FALSE to hide it.

Remarks

CMDIFrameWndEx::EnableFullScreenMode

Enables full-screen mode for the frame window.

void EnableFullScreenMode(UINT uiFullScreenCmd);

Parameters

uiFullScreenCmd
[in] The ID of a command that enables or disables full-screen mode.

Remarks

In full-screen mode, all docking control bars, toolbars and menus are hidden and the active view is resized to occupy the full-screen. When you enable full-screen mode, you must specify an ID of the command that enables or disables it. You can call EnableFullScreenMode from the main frame's OnCreate function. When a frame window is being switched to full-screen mode, the framework creates a floating toolbar with one button that has the specified command ID. If you want to keep the main menu on the screen, call CMDIFrameWndEx::EnableFullScreenMainMenu.

CMDIFrameWndEx::EnableLoadDockState

Enables or disables the loading of the docking state.

void EnableLoadDockState(BOOL bEnable = TRUE);

Parameters

bEnable
[in] TRUE to enable the loading of the docking state, FALSE to disable the loading of the docking state.

Remarks

CMDIFrameWndEx::EnableMDITabbedGroups

Enables or disables the MDI tabbed groups feature for the frame window.

void EnableMDITabbedGroups(
    BOOL bEnable,
    const CMDITabInfo& params);

Parameters

bEnable
[in] If TRUE, the MDI tabbed groups feature is enabled; if FALSE, the MDI tabbed groups feature is disabled.

params
[in] Specifies parameters that the framework applies to child windows that are created in the MDI client area.

Remarks

Use this method to enable or disable the MDI tabbed groups feature. This feature enables MDI applications to display child windows as tabbed windows that are aligned vertically or horizontally within the MDI client area. Groups of tabbed windows are separated by splitters. The user can resize tabbed groups by using a splitter.

The user can:

  • Drag individual tabs between groups.
  • Drag individual tabs to the edge of the window to create new groups.
  • Move tabs or create new groups by using a shortcut menu.
  • Your application can save the current layout of tabbed windows and the list of currently opened documents.

If you call this method with bEnable set to FALSE, params is ignored.

Even if MDI tabbed groups is already enabled, you can call this method again to modify the settings for child windows. Call the method with bEnable set to TRUE and modify the members of the CMDITabInfo object that are specified by the params parameter.

For more information about how to use MDI tabbed groups, see MDI Tabbed Groups.

Example

The following example shows how EnableMDITabbedGroups is used in the VisualStudioDemo Sample: MFC Visual Studio Application.

CMDITabInfo mdiTabParams;
mdiTabParams.m_bTabCustomTooltips = TRUE;

if (bMDITabsVS2005Look)
{
   mdiTabParams.m_style = CMFCTabCtrl::STYLE_3D_VS2005;
   mdiTabParams.m_bDocumentMenu = TRUE;
}
else if (bOneNoteTabs)
{
   mdiTabParams.m_style = CMFCTabCtrl::STYLE_3D_ONENOTE;
   mdiTabParams.m_bAutoColor = bMDITabColors;
}

if (bActiveTabCloseButton)
{
   mdiTabParams.m_bTabCloseButton = FALSE;
   mdiTabParams.m_bActiveTabCloseButton = TRUE;
}

EnableMDITabbedGroups(TRUE, mdiTabParams);

CMDIFrameWndEx::EnableMDITabs

Enables or disables the MDI Tabs feature for the MDI frame window. When enabled, the frame window displays a tab for each MDI child window.

void EnableMDITabs(
    BOOL bEnable=TRUE,
    BOOL bIcons=TRUE,
    CMFCTabCtrl::Location tabLocation=CMFCTabCtrl::LOCATION_BOTTOM,
    BOOL bTabCloseButton=FALSE,
    CMFCTabCtrl::Style style=CMFCTabCtrl::STYLE_3D_SCROLLED,
    BOOL bTabCustomTooltips=FALSE,
    BOOL bActiveTabCloseButton=FALSE);

Parameters

bEnable
Specifies whether tabs are enabled.

bIcons
Specifies whether icons should be displayed on the tabs.

tabLocation
Specifies the location of the tab labels.

bTabCloseButton
Specifies whether to display tab close buttons.

style
Specifies the style of tabs. Use STYLE_3D_SCROLLED for regular tabs or STYLE_3D_ONENOTE for Microsoft OneNote tabs.

bTabCustomTooltips
Specifies whether custom tooltips are enabled.

bActiveTabCloseButton
If TRUE, a Close button will be displayed on the active tab instead of on the right corner of the tab area.

Remarks

Call this method to enable or disable the MDI tabs feature for the MDI frame window. When enabled, all child windows are displayed as tabs.

The tab labels can be located at the top or bottom of the frame, depending on the setting of the parameter tabLocation. You may specify either CMFCTabCtrl::LOCATION_BOTTOM (the default setting) or CMFCTabCtrl::LOCATION_TOP.

If bTabCustomTooltips is TRUE, an AFX_WM_ON_GET_TAB_TOOLTIP message will be sent to the main frame window. Your code can handle this message and provide the framework with custom tooltips for MDI tabs.

Example

The following example shows how EnableMDITabs is used in the MDITabsDemo Sample: MFC Tabbed MDI Application.

void CMainFrame::UpdateMDITabs(BOOL bResetMDIChild)
{
   CMDITabInfo params;
   HWND hwndActive = NULL;

   switch (theApp.m_Options.m_nMDITabsType)
   {
   case CMDITabOptions::None:
   {
      BOOL bCascadeMDIChild = FALSE;

      if (IsMDITabbedGroup())
      {
         EnableMDITabbedGroups(FALSE, params);
         bCascadeMDIChild = TRUE;
      }
      else if (AreMDITabs())

         ::BringWindowToTop(hwndActive);
      }
   }
   break;

   case CMDITabOptions::MDITabsStandard:
      hwndActive = (HWND)m_wndClientArea.SendMessage(WM_MDIGETACTIVE);
      m_wndClientArea.PostMessage(WM_MDIMAXIMIZE, LPARAM(hwndActive), 0L);
      ::BringWindowToTop(hwndActive);

      EnableMDITabs(TRUE, theApp.m_Options.m_bMDITabsIcons, theApp.m_Options.m_bTabsOnTop ? CMFCTabCtrl::LOCATION_TOP : CMFCTabCtrl::LOCATION_BOTTOM, theApp.m_Options.m_nTabsStyle);

      GetMDITabs().EnableAutoColor(theApp.m_Options.m_bTabsAutoColor);
      GetMDITabs().EnableTabDocumentsMenu(theApp.m_Options.m_bMDITabsDocMenu);

Return value

TRUE if the load succeeded; FALSE if the load failed or there's no data to load.

Remarks

To load or save the state of MDI tabs and groups and the list of opened documents, do the following:

  • Call CMDIFrameWndEx::SaveMDIState when the main frame is being closed
  • Call CMDIFrameWndEx::LoadMDIState when the main frame is being created. The recommended place for this call is before the main frame is displayed for the first time. Add CWinAppEx::EnableLoadWindowPlacement (FALSE); before pMainFrame->LoadFrame (IDR_MAINFRAME);. Add CWinAppEx::ReloadWindowPlacement (pMainFrame); after the call to LoadMDIState to display the main frame at the position that was stored in the registry.
  • Override GetDocumentName in the CMDIChildWndEx- derived class if your application displays documents that aren't stored as files. The returned string will be saved in the registry as the document identifier. The base implementation of CMDIChildWndEx::GetDocumentName returns a value obtained from CDocument::GetPathName.
  • Override CMDIFrameWndEx::CreateDocumentWindow to correctly create documents when they're being loaded from the registry. The first parameter is the string that GetDocumentName returned.

Example

The following example shows how LoadMDIState is used in the VisualStudioDemo Sample: MFC Visual Studio Application.

// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

if (cmdInfo.m_nShellCommand == CCommandLineInfo::FileNew)
{
   if (!pMainFrame->LoadMDIState(GetRegSectionPath()))
   {
      m_pStartDocTemplate->OpenDocumentFile(NULL);
   }
}
else
{
   // Dispatch commands specified on the command line
   if (!ProcessShellCommand(cmdInfo))
   {
      return FALSE;
   }
}

CMDIFrameWndEx::MDITabMoveToNextGroup

Moves the active tab from the currently active tabbed window to the next or previous tabbed group.

void MDITabMoveToNextGroup(BOOL bNext=TRUE);

Parameters

void CMainFrame::OnMdiNewHorzTabGroup()
{
   MDITabNewGroup(FALSE);
}

CMDIFrameWndEx::m_bCanConvertControlBarToMDIChild

Specifies whether docking panes can be converted to MDI child windows.

BOOL m_bCanConvertControlBarToMDIChild;

Remarks

Indicates whether docking control bars can be converted to MDI child windows. If this flag is TRUE, the framework handles the conversion automatically when the user selects the Tabbed Document command. The flag is protected and you must explicitly enable this option either by setting m_bCanConvertControlBarToMDIChild in a constructor of a CMDIFrameWndEx-derived class, or by overriding CanConvertControlBarToMDIChild.

The default value is FALSE.

Example

The following example shows how m_bCanConvertControlBarToMDIChild is used in the VisualStudioDemo Sample: MFC Visual Studio Application.

CMainFrame::CMainFrame()
{
   CMFCPopupMenu::SetForceShadow(TRUE);
   m_bCanConvertControlBarToMDIChild = TRUE;
}

CMDIFrameWndEx::m_bDisableSetRedraw

Enables or disables redraw optimization for MDI child windows.

AFX_IMPORT_DATA static BOOL m_bDisableSetRedraw;

Remarks

The default value is TRUE.

Set this flag to FALSE if you want to optimize redrawing of MDI children. In this case, the framework will call SetRedraw (FALSE) for the main frame when the application is changing the active tab.

This flag can cause unwanted effects (such as background applications that become visible). Therefore we recommend that you change the default only if you experience noticeable flickering during MDI tab activation.

CMDIFrameWndEx::NegotiateBorderSpace
