MFCSingle Document (SDI) full screen Program Implementation Method for your reference:

MFC single document (SDI)Full Screen ProgramImplementation ideas:

1. Convert full screen display mode when F11 is pressed
2. Record the current position of the window when the screen is full.
3. Record the Display Properties of the toolbar and status bar
4. Hide/show menu bar
5. Hide/show title bar
6. Maximize/minimize windows

 

Single-document (SDI) full-screen MFC Program ImplementationTechnical points:

1. Add a keydown event for the view. When nchar = 122, add the processing code.
2. Obtain the mainframe pointer in the View: cmainframe * pmain = (cmainframe *) afxgetapp ()-> m_pmainwnd;
3. Add status and other variables to mainframe:

   Public:
   
   Bool m_bfullscreenmode;
   
   Cmenu m_menumainwnd;

   PRIVATE:
   
   Bool m_bstatusbarwasvisible, m_btoolbarwasvisible;

   Crect m_mainrect;

4. Initialize the variable value in the oncreate event of mainframe: This-> m_menumainwnd.loadmenu (idr_mainframe );
   
   This-> setmenu (& m_menumainwnd );
5. The status of full screen initialization in the mainframe constructor is false: This-> m_bfullscreenmode = false;
6. Add the function fullscreenmodeswitch to mainframe.
7. Add full-screen functions to mainframe: fullscreenmodeon and fullscreenmodeoff.
