Use Shell Handle to get window [message #31185]

We are writing an eclipse plug-in that is going to allow us to lock-down
our desktop window. In the Java code I am getting all of the workbench
windows and then I am grabbing the one I want and calling
getShell().handle on it. I can pass that handle down to the native code
using JNI and in Windows I can use that handle and cast it to a HWND and
have controll of that window in the native code. In Linux this does not
work. The Shell handle is not the same as the XLib or Motif
Windows/Widgets. So I am wondering if you know of anyway to use the
getShell() method from the org.eclipse.swt.widgets.shell class so that I
can pass a handle down to Motif/Xlib and use that to be able to control
the window. Previously I was using Xlib and was getting a handle on the
window by cycling through all windows and looking for the window name.
That is no longer possible however because we are not going to know what
the window name will be any longer - i18n.

Any assistance would be greatly appreciated.

thank you,
