The latest version of this topic can be found at CMFCToolBar Class.

The CMFCToolBar class resembles CToolBar Class, but provides additional support for user interface features. These include flat toolbars, toolbars with hot images, large icons, pager buttons, locked toolbars, rebar controls, text under images, background images, and tabbed toolbars. The CMFCToolBar class also contains built-in support for user customization of toolbars and menus, drag-and-drop between toolbars and menus, combo box buttons, edit box buttons, color pickers, and roll-up buttons.

When you process the WM_CREATE message for the main frame window, call either CMFCToolBar::Create or CMFCToolBar::CreateEx to create the toolbar and specify its style.
Call CBasePane::EnableDocking to specify the docking style.

To insert a special button, such as a combo box or drop-down toolbar, reserve a dummy button in the parent resource, and replace the dummy button at runtime by using CMFCToolBar::ReplaceButton. For more information, see [Walkthrough: Putting Controls On Toolbars]--brokenlink--(../Topic/not%20found.md#walkthrough__putting_controls_on_toolbars).

CMFCToolBar is the base class for the MFC Library classes CMFCMenuBar Class, CMFCPopupMenuBar Class, and CMFCDropDownToolBar Class.

Example

The following example demonstrates how to use various methods in the CMFCToolBar class. The example shows how to set the text of the window label of the tool bar, set the borders, set the style of the pane, and enable the Add or Remove Buttons button that appears on the end of the toolbar. This code snippet is part of the IE Demo sample.

   CMFCToolBar     m_wndToolBar;

 m_wndToolBar.SetWindowText (_T("Standard"));
    m_wndToolBar.SetBorders ();

    //------------------------------------
    // Remove toolbar gripper and borders:
    //------------------------------------
    m_wndToolBar.SetPaneStyle (m_wndToolBar.GetPaneStyle() &
        ~(CBRS_GRIPPER | CBRS_BORDER_TOP | CBRS_BORDER_BOTTOM | CBRS_BORDER_LEFT | CBRS_BORDER_RIGHT));

    m_wndToolBar.EnableCustomizeButton (TRUE, ID_VIEW_CUSTOMIZE, _T("Customize..."));

Requirements

Inheritance Hierarchy

CMFCToolBar::AddBasicCommand

Adds a menu command to the list of commands that are always displayed when a user opens a menu.

static void __stdcall AddBasicCommand(UINT uiCmd);

Parameters

[in] uiCmd
Specifies the command to add.

Remarks

A basic command is always displayed when the menu is opened. This method is meaningful when the user chooses to view recently used commands.

Use the CMFCToolBar::SetBasicCommands method to set the list of commands that are always displayed when a user opens a menu. Use the CMFCToolBar::GetBasicCommands method to retrieve the list of basic commands that is used by your application.

CMFCToolBar::AddCommandUsage

Increments by one the counter that is associated with the given command.

static void __stdcall AddCommandUsage(UINT uiCommand);

Parameters

[in] uiCommand
Specifies the command counter to increment.

Remarks

The framework calls this method when the user selects a menu item.

The framework uses command counters to display recently used menu items.

This method increments the command counter by using the CMFCCmdUsageCount::AddCmd method.

CMFCToolBar::AddToolBarForImageCollection

Adds images from the user interface resources to the collection of images in the application.

static BOOL __stdcall AddToolBarForImageCollection(
    UINT uiResID,  
    UINT uiBmpResID=0,  
    UINT uiColdResID=0,  
    UINT uiMenuResID=0,  
    UINT uiDisabledResID=0,  
    UINT uiMenuDisabledResID=0);

Parameters

[in] uiResID
Resource ID of a toolbar with images to load.

[in] uiBmpResID
Resource ID of a bitmap with toolbar images.

[in] uiColdResID
Resource ID of a bitmap with "cold" toolbar images.

[in] uiMenuResID
Resource ID of a bitmap with menu images.

[in] uiDisabledResID
Resource ID of a bitmap with disabled toolbar images.

[in] uiMenuDisabledResID
Resource ID of a bitmap with disabled menu images.

Return Value

TRUE if the method succeeds; FALSE if uiResID or uiBmpResID do not specify valid resources, or another error occurs.

Remarks

Call this method to load a bitmap with toolbar images and add it to the collection of toolbar images. This method creates a temporary toolbar object and calls CMFCToolBar::LoadToolBar.

CMFCToolBar::AdjustLayout

Recalculates the size and position of a toolbar.

virtual void AdjustLayout();

Remarks

Call this method when the toolbar has been created to recalculate its size and position.

The framework calls this method every time that the layout of the toolbar must be changed. For example, the layout must change when the user moves another control bar, resizes an application window, or customizes the toolbar.

Override this method to provide your own dynamic layout in classes that you derive from CMFCToolar.

CMFCToolBar::AdjustSize

Recalculates the size of the toolbar.

void AdjustSize();

Remarks

This method makes sure that the toolbar fits in the bounds of the parent frame. This method does nothing if the toolbar has no parent frame.

The CMFCToolBar::AdjustLayout method calls this method to recalculate the size if the parent of the toolbar is not a CMFCReBar object.

CMFCToolBar::AllowChangeTextLabels

Specifies whether text labels can be shown under images on the toolbar buttons.

virtual BOOL AllowChangeTextLabels() const;

Return Value

TRUE if it is allowed to display text labels below images; otherwise FALSE.

Remarks

This method is called by the customization dialog box to determine whether to enable a Show text labels check-box on the Toolbars page for the selected toolbar.

The default implementation returns TRUE.

Override this method in an object derived from CMFCToolBar and return FALSE when you do not want the user to decide whether text labels are displayed on toolbar buttons under the images.

CMFCToolBar::AllowShowOnList

Determines whether the toolbar is displayed in the list of toolbars on the Toolbars pane of the Customize dialog box.

virtual BOOL AllowShowOnList() const;

Return Value

TRUE if the toolbar object can be displayed in the list box on the toolbar customization page; otherwise FALSE.

Remarks

This method is called by the framework to determine whether the list on the toolbar customization page should include a particular object derived from CMFCToolBar.

The default implementation always returns TRUE. Override this method when you do not want a toolbar to appear in the toolbars list in the customization dialog box.

CMFCToolBar::AreTextLabels

Specifies whether text labels under images are currently displayed on the toolbar buttons.

BOOL AreTextLabels() const;

Return Value

TRUE if the toolbar buttons display text labels below images; otherwise FALSE.

Remarks

Use CMFCToolBar::EnableTextLabels to specify whether the text is displayed. The default value is FALSE. Call CMFCToolBar::AllowChangeTextLabels to specify whether the user can change this setting in the customization dialog box.

CMFCToolBar::AutoGrayInactiveImages

Enable or disables the automatic generation of inactive button images.

static void AutoGrayInactiveImages(
    BOOL bEnable=TRUE,  
    int nGrayImagePercentage=0,  
    BOOL bRedrawAllToolbars=TRUE);

Parameters

[in] bEnable
A Boolean value that specifies whether to dim inactive images. If this parameter is TRUE, inactive images are dimmed. Otherwise, inactive images are not dimmed.

[in] nGrayImagePercentage
Specifies the luminance percentage for inactive images. If bEnable is FALSE, this value is ignored.

[in] bRedrawAllToolbars
A Boolean value that specifies whether to redraw all toolbars in the application. If this parameter is TRUE, this method redraws all toolbars.

Remarks

If bEnable is TRUE, the framework uses nGrayImagePercentage to generate inactive images from the regular images. Otherwise, you must provide the set of inactive images by using the CMFCToolBar::GetColdImages method. By default, this option is disabled.

For more information about the nGrayImagePercentage parameter, see CMFCToolBarImages::GrayImages.

CMFCToolBar::ButtonToIndex

Returns the index of a specified CMFCToolBarButton Class object in this toolbar.

int ButtonToIndex(const CMFCToolBarButton* pButton) const;

Parameters

[in] pButton
A pointer to the toolbar button object.

Return Value

Index of pButton in the internal list of toolbar buttons; or -1 if the specified button is not on this toolbar.

CMFCToolBar::CalcFixedLayout

Calculates the horizontal size of the toolbar.

virtual CSize CalcFixedLayout(
    BOOL bStretch,  
    BOOL bHorz);

Parameters

[in] bStretch
TRUE to stretch the toolbar to the size of the parent frame.

[in] bHorz
TRUE to orient the toolbar horizontally; FALSE to orient the toolbar vertically.

Return Value

A CSize object that specifies the size of the toolbar.

Remarks

This method calculates the size of the toolbar by using the CMFCToolBar::CalcLayout method. It passes the LM_STRETCH flag for the dwMode parameter if bStretch is TRUE. It passes the LM_HORZ flag if bHorz is TRUE.

See the VisualStudioDemo sample for an example that uses this method.

CMFCToolBar::CalcMaxButtonHeight

Calculates the maximum height of buttons in the toolbar.

virtual int CalcMaxButtonHeight();

Return Value

The maximum height of buttons.

Remarks

This method calculates the maximum height among all toolbar buttons on the toolbar. The height may vary depending on factors such as the current toolbar docking state.

Override this method in a class derived from CMFCToolBar to provide your own height calculation.

CMFCToolBar::CalcSize

Called by the framework as part of the layout calculation process.

virtual CSize CalcSize(BOOL bVertDock);

Parameters

[in] bVertDock
TRUE to specify that the toolbar is docked vertically; FALSE to specify that the toolbar is docked horizontally.

Return Value

A CSize object that specifies the overall size of the buttons on the toolbar.

Remarks

This method considers the attributes that affect the size of each button, such as the area of the text label and the border size.

If the toolbar contains no buttons, this method returns the reserved size of a single button by using the CMFCToolBar::GetButtonSize method.

CMFCToolBar::CanBeClosed

Specifies whether a user can close the toolbar.

virtual BOOL CanBeClosed() const;

Return Value

TRUE if the toolbar can be closed by the user; otherwise FALSE.

Remarks

The framework calls this method to determine whether the user can close a toolbar. If the method returns TRUE, the framework enables the SC_CLOSE command in the system menu of the toolbar and the user can close the toolbar by using a check box in the list of toolbars in the customization dialog box.

The default implementation returns TRUE. Override this method in a class derived from CMFCToolBar to make toolbar objects that cannot be closed by the user.

CMFCToolBar::CanBeRestored

Determines whether the system can restore a toolbar to its original state after customization.

virtual BOOL CanBeRestored() const;

Return Value

TRUE if the toolbar can be restored from the application resources; otherwise FALSE.

Remarks

The framework calls this method to determine whether a toolbar can be returned to its original state after customization. The original state is loaded from the application resources.

If CanBeRestored returns TRUE, the Toolbars page of the customization dialog box enables the Reset button for the selected toolbar.

The default implementation returns TRUE if the original resource ID of the toolbar when it was loaded is non-zero. Usually, only user-defined toolbars cannot be restored.

You can override the CanBeRestored method to customize this behavior in derived classes.

CMFCToolBar::CanFocus

Specifies whether the pane can receive focus.

virtual BOOL CanFocus() const;

Return Value

This method returns FALSE.

Remarks

This method overrides the base class implementation, CBasePane::CanFocus, because toolbar objects cannot receive focus.

CMFCToolBar::CanHandleSiblings

Determines whether the toolbar and its sibling are positioned on the same pane.

BOOL CanHandleSiblings();

Return Value

TRUE if the toolbar has a sibling and the toolbar and its sibling are positioned on the same pane; otherwise FALSE.

Remarks

The internal CMFCCustomizeButton::CreatePopupMenu method calls this method to determine how to show the Customize pop-up menu. If this method returns TRUE, the framework displays the Show Buttons on One Row or Show Buttons on Two Rows buttons.

You typically do not have to use this method. To enable the Customize button that appears on the toolbar, call the CMFCToolBar::EnableCustomizeButton method. To enable the Show Buttons on One Row or Show Buttons on Two Rows buttons, call CMFCToolBar::SetSiblingToolBar.

CMFCToolBar::CleanUpImages

Frees the system resources allocated for toolbar images.

static void CMFCToolBar::CleanUpImages();

Remarks

The framework calls this method when an application shuts down.

CMFCToolBar::CleanUpLockedImages

Frees the system resources allocated for locked toolbar images.

void CleanUpLockedImages();

Remarks

Call this method when the visual style of your application changes. See the VisualStudioDemo sample for an example that uses this method.

CMFCToolBar::CommandToIndex

Returns the index of the button in the toolbar with a specified command ID.

int CommandToIndex(
    UINT nIDFind,  
    int iIndexFirst=0) const;

Parameters

[in] nIDFind
Specifies the command ID.

[in] iIndexFirst
Specifies the initial index to start from.

Return Value

Zero-based index of the toolbar button if the method was successful; -1 if there is no button with the specified ID.

Remarks

A CMFCToolBar object maintains an internal list of the buttons on the toolbar. Call this function to retrieve the index of a button in the list given the command ID of the button.

If iIndex is greater than 0, this method ignores any button on the toolbar that has an index less than iIndex.

CMFCToolBar::Create

Creates a CMFCToolBar object.

virtual BOOL Create(
    CWnd* pParentWnd,  
    DWORD dwStyle=AFX_DEFAULT_TOOLBAR_STYLE,  
    UINT nID=AFX_IDW_TOOLBAR);

Parameters

[in] pParentWnd
A pointer to the parent window of the toolbar.

[in] dwStyle
The toolbar style. See Toolbar Control and Button Styles in the Windows SDK for the list of styles.

[in] nID
The ID of the child window of the toolbar.

Return Value

TRUE if this method succeeds; otherwise FALSE.

Remarks

This method creates a control bar and attaches it to the toolbar. It creates the control bar with the TBSTYLE_FLAT style. Call CMFCToolBar::CreateEx if you want a different control bar style.

CMFCToolBar::CreateEx

Creates a CMFCToolBar object that uses additional style options, such as large icons.

virtual BOOL CreateEx(
    CWnd* pParentWnd,  
    DWORD dwCtrlStyle=TBSTYLE_FLAT,  
    DWORD dwStyle=AFX_DEFAULT_TOOLBAR_STYLE,  
    CRect rcBorders=CRect(1,
    1,
    1,
    1),  
    UINT nID=AFX_IDW_TOOLBAR);

Parameters

[in] pParentWnd
A pointer to the parent window of the toolbar.

[in] nID
The ID of the child window of the toolbar.

Return Value

Nonzero if this method succeeds; otherwise 0.

Remarks

This method creates a control bar and attaches it to the toolbar.

Call this method instead of CMFCToolBar::Create when you want to provide specific styles. For example, set dwCtrlStyle to TBSTYLE_FLAT | TBSTYLE_TRANSPARENT to create a toolbar that resembles the toolbars that are used by Internet Explorer 4.

Example

The following example demonstrates how to use the CreateEx method of the CMFCToolBar class. This code snippet is part of the IE Demo sample.

   CMFCToolBar     m_wndToolBar;

 // The this pointer points to CMainFrame class which extends the CFrameWnd class.
    if (!m_wndToolBar.CreateEx (this, TBSTYLE_TRANSPARENT) ||
        !m_wndToolBar.LoadToolBar (IDR_MAINFRAME, uiToolbarColdID, uiMenuID, 
            FALSE /* Not locked */, 0, 0, uiToolbarHotID))
