The workspace manager automatically loads and saves the button's state in the Windows registry. Use the IMPLEMENT_SERIAL macro to make the combo button persistent. Here you should create the CFindComboButton object and return a pointer to it. In the CFindComboButton class, override the CMFCToolbarComboBoxButton::CreateCombo method. Use CCommandManager::GetCmdImage with ID_EDIT_FIND to get the image index.įor a list of available combo box styles, see Combo-Box Styles. Pass the ID_EDIT_FIND_COMBO as the command ID. The constructor of CMFCToolbarComboBoxButton takes three parameters: the command ID of the button, the button image index, and the style of the combo box.
In this example, it's named CFindComboButton. If the user hits the Enter key ( VK_ENTER), post to the main frame window a WM_COMMAND message that contains the ID_EDIT_FIND_COMBO command ID.Ĭreate a class for the Find combo box button, derived from CMFCToolBarComboBoxButton Class. If the user hits the escape key ( VK_ESCAPE), return the focus to the main frame window. This method will enable the combo box to process the WM_KEYDOWN message. In the CFindComboBox class, override the PreTranslateMessage virtual method. However, you must implement a handler for the new command ID_EDIT_FIND_COMBO.Ĭreate a new class, CFindComboBox, derived from CComboBox Class. This ID will be used as the command ID of the Find combo box button.īecause ID_EDIT_FIND is a standard command that is processed by CEditView, you are not required to implement a special handler for this command. In the application resources, add a new button with an ID_EDIT_FIND command ID to a toolbar in your application and to any bitmaps associated with the toolbar.Ĭreate a new menu item with the ID_EDIT_FIND command ID.Īdd a new string "Find the text\nFind" to the string table and assign it an ID_EDIT_FIND_COMBO command ID. Creating the Find Controlįirst, create the Find combo box control:Īdd the button and its commands to the application resources: This example assumes that the document is displayed in a CEditView Class-derived view. The user can type a string in the control and then press the enter key to search a document, or press the escape key to return the focus to the main frame.

This section describes how to create a Find combo box control that appears on a toolbar and contains recent-used search strings. Before you display the Customize dialog box by calling CMFCToolBarsCustomizeDialog::Create, call CMFCToolBarsCustomizeDialog::ReplaceButton to replace the standard button with the new control. When you enable customization, you create the Customize dialog box in the customization handler OnViewCustomize by using the CMFCToolBarsCustomizeDialog Class class. To keep the extended functionality that the toolbar controls provide, you must replace the standard toolbar button with the custom control in the Customize dialog box. By default, the Customize dialog box processes the application menus and builds a list of standard toolbar buttons in each menu category. The Commands tab of the Customize dialog box contains a list of commands that are available in the application. The toolbar state is saved in the Windows registry, and the registry information is loaded and applied after the ReplaceButton method is executed during application startup. If you enabled customization in your application, you may have to reset the toolbar by using the Reset button on the Toolbars tab of the Customize dialog box to see the updated control in your application after recompiling. You can construct the button object on the stack, because ReplaceButton copies the button object and maintains the copy. Replace the dummy button with the new control by using CMFCToolBar::ReplaceButton. In the message handler that processes the AFX_WM_RESETTOOLBAR message, do the following steps:Ĭonstruct the button control by using a CMFCToolbarButton-derived class. Reserve a toolbar image (button icon) for the button in all bitmaps of the parent toolbar.
For more information about how to create buttons by using the Toolbar Editor in Visual Studio, see the Toolbar Editor article.
Reserve a dummy resource ID for the button in the parent toolbar resource. To add a control to a toolbar, follow these steps: In MFC, a toolbar button must be a CMFCToolBarButton Class-derived class, for example CMFCToolBarComboBoxButton Class, CMFCToolBarEditBoxButton Class, CMFCDropDownToolbarButton Class, or CMFCToolBarMenuButton Class. This article describes how to add a toolbar button that contains a Windows control to a toolbar.
