How can I capture the mouse within a client area of a Composite such
that the mouse cannot click outsite the rectangular area designated?

Thanks

Don

I don't know if there is a non platform-specific way to do it.
However, on Windows you can use the ClipCursor API to do it.

Have a look at java.awt.Robot
and moveMove().

Hi Don,

You cannot reliably restrict the pointer from exiting a rectangle. There is
a method Display.setCursorLocation() that would let you move the pointer
back into the rectangle whenever it left, but this is considered to be bad
UI practice and is not offered on all platforms (notably GTK).

However if you meant capture in the traditional sense of having your
composite always notified of mouse events even if the mouse is outside of
it, then you can use Control.setCapture(true).

Not only is there no easy way of doing it, it's certainly bad practice to do so.

In any case, even if you could do this it would be trivial to change to another application (e.g. Alt+Tab) and then go back into your application in a different position.

Why not use a modal Dialog instead? That way, the user can move the mouse around but not do anything with the application until after the operation is complete.

That's our conclusion after some digging ins...
