How do you move software input panel (keyboard) to bottom of windows mobile screen?

问题

I'm trying to move the keyboard to the bottom of the screen to hide the 35px menu bar that it shows by default on windows mobile 5/6. All of the examples I've seen about modifying the menu bar deal with hiding the button "MS_SIPBUTTON". The two parts of my question are:

How can I move the keyboard down 35 pixels on the screen?

And, where is "MS_SIPBUTTON" defined?

回答1:

Part one:

The best way I could muster to move the keyboard was a collection of Windows API calls all referenced from pinvoke.net

First a bunch of DllImport statements:

        [DllImport("coredll.dll", SetLastError = true)]
        private static extern IntPtr FindWindow(string caption, string className);

        [DllImport("coredll.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool GetWindowRect(IntPtr hwnd, out RECT lpRect);

        [DllImport("coredll.dll")]
        internal static extern void MoveWindow(IntPtr hwnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);

        [DllImport("coredll.dll", SetLastError = true)]
        extern static int SipShowIM(int dwFlag);

Next some constants and variables:

        Rectangle sipbutton;
        Rectangle keyboardBackground;
        Rectangle keyboard;

        private const int SW_HIDE = 0;
        private const int SW_SHOW = 1;
        private const int GW_CHILD = 5;
        private const int SIPF_ON = 1;
        private const int SIPF_OFF = 0;

Functions for showing and hiding the SIP button that displays at the bottom of the page. They are called in my constructor and destructor

            public void HideSip()
            {
                IntPtr hTaskBarWindow = FindWindow("MS_SIPBUTTON", null);
                if (hTaskBarWindow != IntPtr.Zero)
                {
                    RECT rct;

                    if (!GetWindowRect(hTaskBarWindow, out rct))
                    {
                        MessageBox.Show("ERROR");
                        return;
                    }

                    Rectangle myRect = new Rectangle();

                    myRect.X = (int)rct.Left;
                    myRect.Y = (int)rct.Top;
                    myRect.Width = (int)(rct.Right - rct.Left + 1);
                    myRect.Height = (int)(rct.Bottom - rct.Top + 1);

                    //save previous state
                    sipbutton = myRect;

                    MoveWindow(hTaskBarWindow, myRect.X, myRect.Y + 1000, myRect.Width, myRect.Height, true);
                    //MoveWindow(hTaskBarWindow, 100, 100, 100, 100, true);
                }
            }

            public void RestoreSip()
            {
                IntPtr hTaskBarWindow = FindWindow("MS_SIPBUTTON", null);
                if (hTaskBarWindow != IntPtr.Zero && sipbutton.Height > 0 && sipbutton.Width > 0)
                {
                    MoveWindow(hTaskBarWindow, sipbutton.X, sipbutton.Y, sipbutton.Width, sipbutton.Height, true);
                }
            }

With that out of the way we need to move the keyboard down to the bottom of the screen:

public void MoveKeyboardDown(int pixelsDown)
        {

            IntPtr hSipWindow = FindWindow("SipWndClass",null);
            if (hSipWindow != IntPtr.Zero)
            {
                RECT rct;

                if (!GetWindowRect(hSipWindow, out rct))
                {
                    MessageBox.Show("ERROR");
                    return;
                }

                Rectangle myRect = new Rectangle();

                myRect.X = (int)rct.Left;
                myRect.Y = (int)rct.Top;
                myRect.Width = (int)(rct.Right - rct.Left + 1);
                myRect.Height = (int)(rct.Bottom - rct.Top + 1);

                //save previous state
                keyboard = myRect;

                MoveWindow(hSipWindow, myRect.X, myRect.Y + pixelsDown, myRect.Width, myRect.Height, true);

            }

            IntPtr hSipWindow2 = FindWindow("SipBackDropWndClass",null);
            if (hSipWindow2 != IntPtr.Zero)
            {
                RECT rct;

                if (!GetWindowRect(hSipWindow2, out rct))
                {
                    MessageBox.Show("ERROR");
                    return;
                }

                Rectangle myRect = new Rectangle();

                myRect.X = (int)rct.Left;
                myRect.Y = (int)rct.Top;
                myRect.Width = (int)(rct.Right - rct.Left + 1);
                myRect.Height = (int)(rct.Bottom - rct.Top + 1);

                //save previous state
                keyboardBackground = myRect;

                MoveWindow(hSipWindow2, myRect.X, myRect.Y + pixelsDown, myRect.Width, myRect.Height, true);

            }


            arPages[iCurrentPage].Invalidate();
        }

        public void RestoreKeyboard()
        {

            IntPtr hSipWindow = FindWindow("SipWndClass", null);
            if (hSipWindow != IntPtr.Zero && keyboard.Height > 0 && keyboard.Width > 0)
            {
                MoveWindow(hSipWindow, keyboard.X, keyboard.Y, keyboard.Width, keyboard.Height, true);
            }

            IntPtr hSipWindow2 = FindWindow("SipBackDropWndClass", null);
            if (hSipWindow2 != IntPtr.Zero && keyboardBackground.Height > 0 && keyboardBackground.Width > 0)
            {
                MoveWindow(hSipWindow2, keyboardBackground.X, keyboardBackground.Y, keyboardBackground.Width, keyboardBackground.Height, true);
            }

        }

When you want to show the keyboard do some thing like this:

    SipShowIM(SIPF_ON);
    MoveKeyboardDown(25);

When you want to hide it do this:

    SipShowIM(SIPF_OFF);
    RestoreKeyboard();

Part two:

I was able to discover the names of windows referenced above using CE Remote Tools/Windows CE Remote Spy. The executable is "ccspy.exe"
