BColumnListView

Hi,
anyone know the BColumnListView? How can I get a MouseUp Event when I click on a row? I want to call a function wenn the mouse is released in the ColumnListView but I don`t know how. Is there an example?

Where can I get the source of the BColumnListView maybe I have an old version. I can´t found the tracker code in the source tree…

ah the columns own a MouseUp function, but I forget to call the SetWantsEvents(true) function so nothing happens…

But this MouseUp function is only called when the click was on a row. How can I get an Mouse click when a click was on an empty space in the list?
(I want to draw an rect like in the tracker to select the items)
