wpf - Snap 应用程序和 Word

Question

我正在制作一个应用程序，我希望用户能够单击一个按钮，捕捉 Word 或其他程序以占用 70% 的屏幕，而我的应用程序占用剩余的 30%。

这可能吗？

有本地方法吗？

有第三方的方法吗？

在此先感谢您的帮助！

这确实是可能的，试试这个功能：

[DllImport("user32.dll")]
private static extern bool GetWindowRect(IntPtr hwnd, ref Rectangle rectangle);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern bool PostMessage(IntPtr hWnd, uint msg, int WPARAM, int LPARAM);
[DllImport("user32.dll", SetLastError = true)]
internal static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int, Y, int cx, int cy, uint uFlags);

public const uint WM_SYSCOMMAND = 0x0112;
public const int SC_NEXTWINDOW = 0xF040;
public static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);
public static readonly IntPtr HWND_NOTOPMOST = new IntPtr(-2);
public static readonly IntPtr HWND_TOP = new IntPtr(0);
public static readonly IntPtr HWND_BOTTOM = new IntPtr(1);
public const UInt32 TOPMOST_FLAGS = 0x0002 | 0x0001;

Public void resisezeWindow(String procesname, int Width, int Height, Boolean bringtofront)
{
    foreach (Process proc in Process.GetProcesses())
    {
        IntPtr id = proc.MainWindowHandle;
        Rectangle rect = new Rectangle();
        GetWindowRect(id, ref rect);
        if (proc.MainWindowTitle.Contains(procesname))
        {
            PostMessage(proc.Handle, WM_SYSCOMMAND, SC_NEXTWINDOW, 0);
                    MoveWindow(id, 0, 0, Width, Height, true);
                    if(bringtofront) SetWindowPos(id, HWND_TOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS);
                    proc.Refresh();
        }
    }
}
