How MFC implements full-screen functionality

Many players have shortcut control windows that are displayed in full screen mode. Adding full-screen functionality to your application does not require a lot of code, such as adding full-screen functionality to a dialog-based application that only requires the following small amount of code to work.

Many players have shortcut control windows that are displayed in full screen mode. Adding full-screen functionality to your application does not require a lot of code, such as adding full-screen functionality to a dialog-based application that only requires the following small amount of code to work.

The code is as follows:

void Cfullscreendlg::fullscreenview (void)

{

RECT Rectdesktop;

Windowplacement wpnew;

if (! IsFullScreen ())

{

We ' ll need these to restore the original state.

GetWindowPlacement (&m_wpprev);

Adjust RECT to new size of window

:: GetWindowRect (:: GetDesktopWindow (), &rectdesktop);

:: Adjustwindowrectex (&rectdesktop, GetStyle (), FALSE, Getexstyle ());

Remember this for OnGetMinMaxInfo ()

M_rcfullscreenrect = Rectdesktop;

Wpnew = M_wpprev;

Wpnew.showcmd = Sw_shownormal;

Wpnew.rcnormalposition = Rectdesktop;

M_bfullscreen=true;

}

Else

{

Revert to the original window state when exiting full screen

M_bfullscreen=false;

Wpnew = M_wpprev;

}

SetWindowPlacement (&wpnew);

}

void Cfullscreendlg::ongetminmaxinfo (minmaxinfo* lpmmi)

{

Todo:add your message handler code here and/or call default

if (IsFullScreen ())

{

Lpmmi->ptmaxsize.y = M_rcfullscreenrect.height ();

Lpmmi->ptmaxtracksize.y = lpmmi->ptmaxsize.y;

lpmmi->ptmaxsize.x = M_rcfullscreenrect.width ();

lpmmi->ptmaxtracksize.x = lpmmi->ptmaxsize.x;

}

Cdialog::ongetminmaxinfo (Lpmmi);

}

BOOL Cfullscreendlg::isfullscreen (void)

{

Record whether the window is currently in full-screen state

return m_bfullscreen;

}650) this.width=650; "src=" Http://images.enet.com.cn/end.gif "height=" one "width=" one "border=" 0 "alt=" end.gif "/>

The code is complete.
