关于输入汉字文字的问题
最近做到的项目需要用到在贴图区域中输入文字的内容...

以前一直都是用textbox之类的控件输入文字

现在要在rectangle中输入文字,请问要怎么操作才可以激活输入法?

如果只是英文输入的话也就只需要纪录下键盘就得了,可是汉字输入的话...没思路

求思路!如何实现在点击一个rectangle后可以输入文字数据的功能!

这个我前年弄过，现在大记不清了，大概就是以下的一些API和处理，你可以搜索一下这些API，可能能找到完整示例。

C# code

        //光标API        [DllImport("user32.dll")]        static extern bool CreateCaret(IntPtr hWnd, IntPtr hBitmap, int nWidth, int nHeight);        [DllImport("user32.dll")]        static extern bool ShowCaret(IntPtr hWnd);        [DllImport("User32.dll")]        static extern bool HideCaret(IntPtr hWnd);        [DllImport("User32.dll")]        static extern bool SetCaretPos(int x, int y);        [DllImport("user32.dll")]        static extern bool DestroyCaret();        //输入法相关API        public const int WM_IME_SETCONTEXT = 0x0281;        private const int WM_IME_CHAR = 0x0286;        private const int WM_CHAR = 0x0102;        private const int WM_IME_COMPOSITION = 0x010F;        private const int GCS_COMPSTR = 0x0008;        [DllImport("Imm32.dll")]        public static extern IntPtr ImmGetContext(IntPtr hWnd);        [DllImport("Imm32.dll")]        public static extern IntPtr ImmAssociateContext(IntPtr hWnd, IntPtr hIMC);        [DllImport("imm32.dll")]        static extern int ImmGetCompositionString(IntPtr hIMC, int dwIndex, StringBuilder lPBuf, int dwBufLen);        private int GCS_RESULTSTR = 0x0800;        private const int HC_ACTION = 0;        private const int PM_REMOVE = 0x0001;        //大概处理过程        protected override void WndProc(ref Message m)        {            base.WndProc(ref m);            if (m.Msg == WM_IME_SETCONTEXT && m.WParam == (IntPtr)1)            {                ImmAssociateContext(this.Handle, m_hImc);            }            switch (m.Msg)            {                case WM_CHAR:                    char a = (char)m.WParam; //英文                        //...............                    break;                case WM_IME_CHAR:                    if (m.WParam.ToInt32() == PM_REMOVE)                    {                        int size = ImmGetCompositionString(m_hImc, GCS_COMPSTR, null, 0);                        size += 2;                        ImmGetCompositionString(m_hImc, GCS_RESULTSTR, str, size);                        //..............                    }                    break;            }        }
