The runtime program interface is shown in the interface. The program has a toolbar for displaying two command buttons, one for demonstrating how the button is inspected, and the other is disabled / allowed according to the status of the first button. (Set check status and allowed status through onupdateCommand) In addition, there is an input box and button on the Dialog Bar. The prohibition / allowance of the two sub-windings is also determined according to the status status on the toolbar, when Press Dialog Bar The text content in the input box will appear when the button is button. The first part of the state bar is used to display various prompts, and the second part is used to display the current time with onupdateCommand. At the same time, in the program, how to set up a command interpretation of the menu item (will display the first part of the status bar) and how to set the toolbar prompt (using a small Tooltip window).
Generating App: Generate an MFC engineering, legend, and set to a single document interface legend, finally select the toolbar, status and rebar support, legend
Modify menu: Use the resource editor to delete an extra menu and add a new pop-up menu and three submenus, the legend, respectively:
Name ID Description Character Checkidm_ChecksetCheck Demo / NSETCHECKSETCHECK DEMO / NSETCHECK DEMODISABLEIDM_DISABEDISABLE DEMO / NDISABLE DEMOSHOWTEXT ON DIALOGBARIDM_SHOW_TXTSHOWTEXT ON DIALOGBAR DEMO / NSHOWTEXT On Dialogbar
The string before / n will be displayed in the status bar as a command, and the portion after the / n will appear as a prompt of the toolbar button with the same ID in the Tooltip window.
Modify Dialog Bar: Add a input box and button to the Dialog Bar, the button has the same ID as IDM_SHOW_TXT with a menu item, which can use the mapping menu message to process the button message (of course, using different ID values can also be used with ON_COMMAND) Map the button message on the Dialog Bar, but ClassWizard does not provide a way to map to the Dialog Bar, which can only be manually adding message mapping code). legend
Modifying toolbar: Add two buttons to the toolbar, IDM_CHECK and IDM_DISABLE and two menu items have the same ID value. legend
Add a message mapping and update command to three menu items using ClassWizard. legend
