Unity使用Windows原生user32.dll接口调整窗口分辨率

使用user32.dll的API

    //窗口样式[DllImport("user32.dll")]static extern IntPtr SetWindowLong(IntPtr hwnd, int _nIndex, int dwNewLong);//窗口分辨率和位置[DllImport("user32.dll")]static extern bool SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);//获取当前激活窗口[DllImport("user32.dll", EntryPoint = "GetForegroundWindow")]static extern IntPtr GetForegroundWindow();[DllImport("user32.dll")]static extern IntPtr FindWindow(string strClassName, int nptWindowName);//窗口拖动[DllImport("user32.dll")]public static extern bool ReleaseCapture();[DllImport("user32.dll")]public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);[DllImport("user32.dll", SetLastError = true)]//得到窗口的样式private static extern int GetWindowLong(IntPtr hWnd, int nIndex);[DllImport("user32.dll")]public static extern bool ShowWindow(System.IntPtr hwnd, int nCmdShow);//获取窗口位置以及大小[DllImport("user32.dll")][return: MarshalAs(UnmanagedType.Bool)]public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);[StructLayout(LayoutKind.Sequential)]

使用的参数

    private const int SWP_SHOWWINDOW = 0x0040;//边框样式private const int GWL_STYLE = -16;private const int GWL_EXSTYLE = -20;//窗口有细线边框private const int WS_BORDER = 1;//窗口有一个最大化按钮private const int WS_MAXIMIZEBOX = 0x00010000;//窗口有一个最小化按钮private const int WS_MINIMIZEBOX = 0x00020000;//窗口是一个重叠窗口。重叠窗口有标题栏和边框。private const int WS_OVERLAPPED = 0x00000000;//有标题栏private const int WS_TILEDWINDOW = (WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX);//隐藏标题栏图标private const int WS_POPUP = 0x800000;//窗口的标题栏上有一个窗口菜单。也必须指定ws_CAPTION样式。private const int WS_SYSMENU = 0x80000;//最大最小化private const int SW_SHOWMINIMIZED = 2;//(最小化窗口)private const int SW_SHOWMAXIMIZED = 3;//最大化窗口//去除标题栏保留边框private const int WS_CAPTION = 0x00C00000;private const int WS_THICKFRAME = 0x00040000;

无标题栏窗口分辨率修改

    /// <summary>/// 隐藏标题栏修改分辨率/// </summary>/// <param name="winWidth"></param>/// <param name="winHeight"></param>/// <param name="winPosX"></param>/// <param name="winPosY"></param>void ChangeScreenSizeHide(int winWidth, int winHeight, int winPosX, int winPosY){if (titleBarStyles== TitleBarStyles.Show){//去除标题栏（不可拖拽缩放）；一定要加SetWindowPos（）设置才会立即生效SetWindowLong(GetForegroundWindow(), GWL_STYLE, WS_POPUP);//去除标题栏（可拖拽缩放）//SetWindowLong(GetForegroundWindow(), GWL_STYLE, GetWindowLong(GetForegroundWindow(), GWL_STYLE) & ~WS_CAPTION | WS_THICKFRAME);}ChangeScreenSize(winWidth, winHeight, winPosX, winPosY);titleBarStyles = TitleBarStyles.Hide;}

有标题栏窗口分辨率修改

    //不隐藏标题栏修改分辨率void ChangeScreenSizeShow(int winWidth, int winHeight, int winPosX, int winPosY){if (titleBarStyles == TitleBarStyles.Hide){SetWindowLong(GetForegroundWindow(), GWL_STYLE, GetWindowLong(GetForegroundWindow(), GWL_STYLE) | WS_TILEDWINDOW);}ChangeScreenSize(winWidth, winHeight, winPosX, winPosY);titleBarStyles = TitleBarStyles.Show;}

窗口最大化

    /// <summary>/// 窗口最大化/// </summary>public void SetMaxWindows(){int currMaxScreenHeight = Screen.currentResolution.height - GetTaskBarHeight();SetWindowPos(GetForegroundWindow(), 0, 0, 0, Screen.currentResolution.width, currMaxScreenHeight, SWP_SHOWWINDOW);}/// <summary>/// 获取任务栏高度/// </summary>/// <returns>任务栏高度</returns>private int GetTaskBarHeight(){int taskbarHeight = 0;IntPtr hWnd = FindWindow("Shell_TrayWnd", 0);RECT rect = new RECT();GetWindowRect(hWnd, ref rect);taskbarHeight = (int)rect.Bottom - (int)rect.Top;Debug.Log(taskbarHeight);return taskbarHeight;}

窗口最小化

    /// <summary>/// 最小化窗口/// </summary>public void SetMinWindows(){ShowWindow(GetForegroundWindow(), SW_SHOWMINIMIZED);}

窗口拖动

    /// <summary>/// 拖动窗口/// </summary>/// <param name="window">当前句柄</param>public void DragWindow(){ReleaseCapture();SendMessage(GetForegroundWindow(), 0xA1, 0x02, 0);SendMessage(GetForegroundWindow(), 0x0202, 0, 0);}

全屏

    /// <summary>/// 全屏/// </summary>public void SetFullScreen(){ShowWindow(GetForegroundWindow(), SW_SHOWMAXIMIZED);}
