Question

的延续

我终于得到了我想要的托盘图标： 1.托盘中的图标 2.单击打开小托盘窗口 3.单击托盘窗口打开主窗口

唯一的问题是我希望小型中间窗口远离托盘。我会说它靠近已启动它的托盘图标，如下图所示。

托盘图标的代码（从主窗口启动）是：

 var tim = new TrayIconMenuWindow.TrayIconMenuWindow();
 tim.WindowStartupLocation = WindowStartupLocation.CenterOwner;<------
 tim.ShowDialog();
 this.Visibility = Visibility.Visible;

我尝试了所有的启动位置但没有帮助。感谢名单

Answer 1

如果您想要屏幕右下方的窗口，您可以使用以下内容：

Rectangle workingArea = Screen.GetWorkingArea(this);
this.Location = new Point(workingArea.Right - Size.Width,
                                  workingArea.Bottom - Size.Height);

修改我刚刚意识到你在WPF工作。如果是这种情况，请使用以下代码：

var screenSize = System.Windows.SystemParameters.WorkArea; this.Left = screenSize.Right - this.Width; this.Top = screenSize.Bottom - this.Height;

如果您希望NotifyIcon旁边显示一个窗口，例如与NotifyIcon关联的ContextMenuStrip，则需要在屏幕中获取NotifyIcon的确切位置，然后调整窗口的位置。您可以在以下位置找到示例：

rzhw/SuperNotifyIcon

它非常冗长，但获取NotifyIcon位置的代码可以更短：

using System;
using System.Reflection;
using System.Runtime.InteropServices;
using System.Windows;
using System.Windows.Forms;

public static class NotifyIconRect
{
    #region Win32

    [DllImport("Shell32.dll", SetLastError = true)]
    private static extern int Shell_NotifyIconGetRect(
        [In] ref NOTIFYICONIDENTIFIER identifier,
        out RECT iconLocation);

    [StructLayout(LayoutKind.Sequential)]
    private struct NOTIFYICONIDENTIFIER
    {
        public uint cbSize;
        public IntPtr hWnd;
        public uint uID;
        public GUID guidItem; // System.Guid can be used.
    }

    [StructLayout(LayoutKind.Sequential)]
    private struct GUID
    {
        public uint Data1;
        public ushort Data2;
        public ushort Data3;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]
        public byte[] Data4;
    }

    [StructLayout(LayoutKind.Sequential)]
    private struct RECT
    {
        public int left;
        public int top;
        public int right;
        public int bottom;

        public static implicit operator Rect(RECT rect)
        {
            if ((rect.right - rect.left < 0) || (rect.bottom - rect.top < 0))
                return Rect.Empty;

            return new Rect(
                rect.left,
                rect.top,
                rect.right - rect.left,
                rect.bottom - rect.top);
        }
    }

    #endregion

    public static Rect GetNotifyIconRect(NotifyIcon notifyIcon)
    {
        NOTIFYICONIDENTIFIER identifier;
        if (!TryGetNotifyIconIdentifier(notifyIcon, out identifier))
            return Rect.Empty;

        RECT iconLocation;
        int result = Shell_NotifyIconGetRect(ref identifier, out iconLocation);

        switch (result)
        {
            case 0: // 0 means S_OK.
            case 1: // 1 means S_FALSE.
                return iconLocation;
            default:
                return Rect.Empty;
        }
    }

    private static bool TryGetNotifyIconIdentifier(NotifyIcon notifyIcon, out NOTIFYICONIDENTIFIER identifier)
    {
        identifier = new NOTIFYICONIDENTIFIER { cbSize = (uint)Marshal.SizeOf(typeof(NOTIFYICONIDENTIFIER))    };

        int id;
        if (!TryGetFieldValue(notifyIcon, "id", out id))
            return false;

        NativeWindow window;
        if (!TryGetFieldValue(notifyIcon, "window", out window))
            return false;

        identifier.uID = (uint)id;
        identifier.hWnd = window.Handle;
        return true;
    }

    private static bool TryGetFieldValue<T>(object instance, string fieldName, out T fieldValue)
    {
        fieldValue = default(T);

        var fieldInfo = instance.GetType().GetField(fieldName, BindingFlags.NonPublic | BindingFlags.Instance);
        if (fieldInfo == null)
            return false;

        var value = fieldInfo.GetValue(instance);
        if (!(value is T))
            return false;

        fieldValue = (T)value;
        return true;
    }
}

这段代码有点棘手，因为它通过反射获取NotifyIcon的私有字段值，但我不知道有任何其他方法可以完成此操作。
