Allow Draging Toolwindow without Title ?

hi,

in one of my requirements I am hiding Title bar with HasTitle Bar but I still want to use it for Drag and Drop so how can i spacify some other part of my toolwindow to act as Holding part ( as Title is working in default case) where the user can hold Left click and put it where ever it wanted to put...(like small Image in my ToolWindow)


thanks in Advance,
