Please try to use a better english, because I don't really understand 
what you are saying.

Provide me a little project that shows your problem (telling what you 
want to do, and what you get). This is the fastest way for me to fix the 
problems.

Create a DesktopWatcher object, passing TRUE to its constructor, so that 
you watch the root window of the screen.

The DesktopWatcher raises the following events:
- Windows: the desktop windows list has changed (a top-level window has 
been created of destroyed). Use Desktop.Windows to browse them.
- Change: the current virtual desktop has changed.
- Count: the number of virtual desktops has changed.
- ActiveWindow: the active window has changed. Use Desktop.ActiveWindow 
to get it.
- Geometry: the geometry of the desktop has changed.

The Desktop.Windows returns sort of array of DesktopWindow objects. 
DesktopWindow encapsulates a X11 window id into a object with properties 
and methods to move the window, resize it, get its icon...

With that, you should have everything to create a taskbar in your panel, 
and manage virtual desktops.

Finally, you can create DesktopWatcher objects to watch individual 
top-level windows, by using their window id.
