Windows Mobile 6.5 控件风格

引：在做Windows Mobile 6.5自绘listview时，当菜单选中时，为达到与WM6.5统一的风格，在文档中没有找到相应绘制listview 选中状态的函数。通过分析，绘制函数必定在coredll中，查找coredll.def文件，发现三个函数。

关于设置默认listview控件的方法见如下：

The secret is in the extended style LVS_EX_THEME that needs to be applied to a ListView. It could be done by sending LVM_SETEXTENDEDLISTVIEWSTYLE to the control. I've wrapped appropriate P/Invoke calls in the following extention method:

 const int LVS_EX_THEME = 0x02000000;

/// <summary>

/// Sets theme style to a listview

/// </summary>

/// <param name="listView">ListView instance</param>

public static void SetThemeStyle(this ListView listView)

{

     // Retreive the current extended style

     int currentStyle = SendMessage(listView.Handle,

                                  (uint)LVM_GETEXTENDEDLISTVIEWSTYLE, 0, 0);

     // Assign the LVS_EX_THEM style

     SendMessage(listView.Handle, (uint)LVM_SETEXTENDEDLISTVIEWSTYLE, 0,

currentStyle | LVS_EX_THEME);

           

}

But wait there's more... While looking up the values for the P/Invoke messages in the commctrl.h, my eyes cought the forgotten LVM_SETBKIMAGE message which could be used to assign a background image to a ListView. This is how another extention method would look like:

/// <summary>

/// Sets background image to a listview

/// </summary>

/// <param name="listView">ListView instance.</param>

/// <param name="path">string path to an image.</param>

public static void SetBackgroundImage(this ListView listView, string path)

{

      // Create bitmap

      Bitmap bitmap = new Bitmap(path);

      // Retrieve HBITMAP

      IntPtr hBitmap = bitmap.GetHbitmap();

      // Dispose the managed bitmap

      bitmap.Dispose();

      // Prepare structure

      LVBKIMAGE lvImage = new LVBKIMAGE();

      lvImage.hbm = hBitmap;

      lvImage.ulFlags = LVBKIF_SOURCE_HBITMAP;

      // Assign an image

      SendMessage(listView.Handle, LVM_SETBKIMAGE, 0, ref lvImage);

 

 }
