Winforms 将Windows窗体设置为win32窗口的弹出子窗口
Windows屏幕保护程序API为我提供了Winforms 将Windows窗体设置为win32窗口的弹出子窗口,winforms,winapi,Winforms,Winapi,Windows屏幕保护程序API为我提供了/c:xxxx的命令行参数,其中xxxx是该窗口的句柄,该窗口应该是我为配置屏幕保护程序而创建的任何子窗口的父窗口 目前我有以下助手: [DllImport("user32.dll")] static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); const int GWL_STYLE = -16; [Flags] public
/c:xxxx
的命令行参数,其中xxxx
是该窗口的句柄,该窗口应该是我为配置屏幕保护程序而创建的任何子窗口的父窗口
目前我有以下助手:
[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
const int GWL_STYLE = -16;
[Flags]
public enum WindowStyle : ulong
{
WS_OVERLAPPED = 0x00000000,
WS_POPUP = 0x80000000,
WS_CHILD = 0x40000000,
WS_MINIMIZE = 0x20000000,
WS_VISIBLE = 0x10000000,
WS_DISABLED = 0x08000000,
WS_CLIPSIBLINGS = 0x04000000,
WS_CLIPCHILDREN = 0x02000000,
WS_MAXIMIZE = 0x01000000,
WS_CAPTION = 0x00C00000, // WS_BORDER | WS_DLGFRAME
WS_BORDER = 0x00800000,
WS_DLGFRAME = 0x00400000,
WS_VSCROLL = 0x00200000,
WS_HSCROLL = 0x00100000,
WS_SYSMENU = 0x00080000,
WS_THICKFRAME = 0x00040000,
WS_GROUP = 0x00020000,
WS_TABSTOP = 0x00010000,
WS_MINIMIZEBOX = 0x00020000,
WS_MAXIMIZEBOX = 0x00010000,
WS_TILED = WS_OVERLAPPED,
WS_ICONIC = WS_MINIMIZE,
WS_SIZEBOX = WS_THICKFRAME
};
[DllImport("user32.dll")]
static extern UIntPtr SetWindowLongPtr(IntPtr hWnd, int nIndex, UIntPtr dwNewLong);
[DllImport("user32.dll", SetLastError = true)]
static extern UIntPtr GetWindowLongPtr(IntPtr hWnd, int nIndex);
[DllImport("user32.dll")]
static extern bool GetClientRect(IntPtr hWnd, out Rectangle lpRect);
public static void SetParent(Control child, IntPtr parent)
{
SetParent(child.Handle, parent);
}
public static void AddStyle(Control child, WindowStyle addstyle)
{
UIntPtr style = GetWindowLongPtr(child.Handle, GWL_STYLE);
style = new UIntPtr(style.ToUInt64() | (UInt64)addstyle);
SetWindowLongPtr(child.Handle, GWL_STYLE, style);
}
public static Rectangle GetClientRect(IntPtr window)
{
Rectangle rect;
GetClientRect(window, out rect);
return rect;
}
…
然后在Windows窗体对话框中:
public ConfigForm(IntPtr parentHWnd)
{
InitializeComponent();
User32.SetParent(this, parentHWnd);
User32.AddStyle(this, User32.WindowStyle.WS_POPUP);
}
弹出标志似乎被忽略,因为Windows窗体是作为子窗体(而不是弹出窗口)绘制的,在父窗体的边界内剪切,并且存在各种各样的绘图问题。检查后,我添加WS_POPUP
之前表单的窗口样式为0x06CF0000
如何使Windows窗体对话框成为一个实际的弹出窗口?也就是说,与提供的父句柄是模态的,但不剪切到父窗口的边界?
SetParent()
使其成为子窗口。子窗口不能是弹出窗口。WS_子项
和WS_弹出式
样式是互斥的,就像在MSDN上一样。那么如何将对话框与父项关联?
