如果您获得桌面的窗口句柄,您可以创建一个新窗口并将您自己的自定义窗口添加为它的子窗口。把它放在列表视图后面可能会给你你需要的结果,尽管我不能 100% 确定透明度的效果如何。
找到一些代码 - 如果您不需要处理多个改变形状的屏幕,您需要的大部分内容都在第一部分。
public void SetDesktopWindows()
{
Thread.Sleep(0);
while (this.Count < Screen.AllScreens.Length)
{
OrangeGuava.Desktop.DesktopWindow.DesktopControl dtc = new OrangeGuava.Desktop.DesktopWindow.DesktopControl();
User32.SetParent(dtc.Handle, User32.FindWindow("ProgMan", null));
this.Add(dtc);
}
int minx = 0;
int miny = 0;
foreach (Screen screen in Screen.AllScreens)
{
if (screen.Bounds.Left < minx) minx = screen.Bounds.Left;
if (screen.Bounds.Top < miny) miny = screen.Bounds.Top;
}
for (int i = Screen.AllScreens.Length; i < Count; i++)
{
OrangeGuava.Desktop.DesktopWindow.DesktopControl dtc = (OrangeGuava.Desktop.DesktopWindow.DesktopControl)this[i];
dtc.Hide();
}
for (int i = 0; i < Screen.AllScreens.Length; i++)
{
OrangeGuava.Desktop.DesktopWindow.DesktopControl dtc = (OrangeGuava.Desktop.DesktopWindow.DesktopControl)this[i];
dtc.DeviceId = i.ToString();
Rectangle r = Screen.AllScreens[i].WorkingArea;
r.X -= minx;
r.Y -= miny;
dtc.SetBounds(r.X, r.Y, r.Width, r.Height);
dtc.displaySettingsChanged(null, null);
}
