Winamp & Shoutcast Forums - How to access a SysListView32 control

I write a script to create a SysListView32 control using nsDialogs, but it could only show a box. I want to insert columns and items into it, but after read the Messages of SysListView32 control at MSDN, I know that I must use API to access this control as some of the messages need "the pointer to an LVCOLUMN structure that contains the attributes of the new column".

I don't know how to use System plug-in to access it. I hope that nsDialogs provide more controls support, such as msctls_trackbar32, SysListView32, SysTreeView32 etc. in future.

PHP Code:
