about adding pop menu in treeview

I'am thinking about adding pop menu in treeview.
the nautilus architechture(2.4 version) is not perfect enough for us to add the enhancement of adding pop menu in treeview. But we really need this feature in our desktop linux distribution, so I'am planning implement this feature in following way, though it is not a satisfactory way.

1. make a class (say, call it FMSimPopmenuView) which inherits from FMDirectoryView, because FMDirectoryView supports almost all the file operations related to pop-memu, and also FMDirectoryView has it's own pop menu.
  the FMSimPopmenuView is invisible, so it works in background
2. pop up menu in treeview by doing some event simulation. that is , when we right-click some node in the treeview, the change location operation is not performed for treeview , the same is for other views such as FMDirectoryView/location bar etc. Instead , FMSimPopmenuView is made to change location to "the parent node of the selected node", and then is set selection to "the item coresponding to the selected node in the treeview". finally the popmenu for FMSimPopmenuView is activated
