在 MFC 中将应用程序移动到第二个显示器

Question

我正在 VS2008 VC++.net 中开发一个应用程序，

我想将该应用程序移动到辅助监视器。不是通过使用鼠标单击和拖动来实现的。

有没有像MoveToMonitor这样的功能，可以通过按按钮或任何快捷键来实现。 然后它应该移动到辅助监视器。

您应该能够调用 GetMonitorInfo 并移动你的窗口在那里。

看这里'
MFC 示例多显示器支持GetSystemMetrics EnumDisplayMonitors 和 GetMonitorInfo' 了解更多信息。

Using the code

CMointor is a basic MFC class that allows you to safely use the multiple-monitor API on any Win32 platform. 

There are three classes in this library:

CMonitors represents the collection of monitors currently attached to the system and wraps the EnumDisplayMonitors API function.

  Collapse Copy Code
//CMonitors' interface
CMonitor GetMonitor( const int index ) const;
int GetCount() const; 

//returns the monitor closest to the specified item
static CMonitor GetNearestMonitor( const LPRECT lprc );
static CMonitor GetNearestMonitor( const POINT pt );
static CMonitor GetNearestMonitor( const CWnd* pWnd );

//is the specificed item visible on any monitor
static BOOL IsOnScreen( const POINT pt );
static BOOL IsOnScreen( const CWnd* pWnd );
static BOOL IsOnScreen( const LPRECT lprc );

//returns the rectangle encompassing all monitors
static void GetVirtualDesktopRect( LPRECT lprc );

//determines whether the given handle is a valid monitor handle
static BOOL IsMonitor( const HMONITOR hMonitor );
static CMonitor GetPrimaryMonitor();
static BOOL AllMonitorsShareDisplayFormat();

static int GetMonitorCount();
CMonitor is a wrapper around an HMONITOR handle (returned from EnumDisplayMonitors) and the GetMonitorInfo function. With CMonitor you can get at the characteristics of a given monitor.

  Collapse Copy Code
//The interface of CMonitor            
void Attach( const HMONITOR hMonitor );
HMONITOR Detach();

void ClipRectToMonitor( LPRECT lprc, 
                        const BOOL UseWorkAreaRect = FALSE ) const;
void CenterRectToMonitor( LPRECT lprc, 
                          const BOOL UseWorkAreaRect = FALSE ) const;
void CenterWindowToMonitor( CWnd* const pWnd,
                            const BOOL UseWorkAreaRect = FALSE ) const;

//creates a device context for the monitor - the client is responsible for 
// DeleteDC
HDC CreateDC() const;

void GetMonitorRect( LPRECT lprc ) const;
//the work area is the monitor rect minus the start bar
void GetWorkAreaRect( LPRECT lprc ) const;

void GetName( CString& string ) const;

int GetBitsPerPixel() const;

//determines if the specified item on the monitor
BOOL IsOnMonitor( const POINT pt ) const;
BOOL IsOnMonitor( const CWnd* pWnd ) const;
BOOL IsOnMonitor( const LPRECT lprc ) const;

BOOL IsPrimaryMonitor() const;
BOOL IsMonitor() const;

CMonitorDC is a CDC derived class that represents a monitor specific device context. I haven't really gone to far with this class but it seemed like a logical part of the library.  

Known Limitations

CMonitor and CMonitors rely on the assumption that a monitor handle does not change. This has proved to be a safe assumption empirically but isn't nessecarily a guarantee.

如果您使用的是 Window 7，则在显示器之间移动窗口为 Windows-箭头

Answer 2

您可以使用 MoveWindow （或 SetWindowPos，尽管在​​这种情况下您不需要它可以执行的额外操作）将窗口移动到桌面上显示的部分有问题的监视器。您可以使用EnumDisplayMonitors（以及其他可能性）找到它，它会告诉您与每个监视器关联的矩形。
