Yes, unless you specify your window as "override redirect" or
change the matchbox window manager -use_dialog_mode arguments
in device bootup:
http://matchbox-project.org/documentation/manual/wm.html

Note that override redirect means that windows are not managed
by the window manager at all, if you top some other window,
the override redirect one is lost by the user (override redirect
is intended for popups that go away when you release stylus or
press anywhere on screen).
