I was meaning that the python code should create a subclass of
PopupApplet. For instance, the
kdeexamples/plasma/python/applets/pyhello is a popup applet, but
currently it is a subclass of Applet:
class Hello(Applet):
def __init__(self, parent, args = None):
Applet.__init__(self, parent)
self.frame = None
In Ruby I added Popup and Containment classes, which currently don't
do anything:
class Containment < Applet
def initialize(parent, args = nil)
super(parent, args)
end
end
class PopupApplet < Applet
def initialize(parent, args = nil)
super(parent, args)
end
end
Strictly speaking they aren't needed because method calls are just
forwarded to the Ruby instance that wraps the C++ instance created by
the Plasma runtime, just as happens in Python. But I added them
because I think it makes the application code clearer, and maybe in
the future there will actually be some code in the PopupApplet and
Containment classes that isn't in the Applet class. Then any current
Ruby popup applets and containments will be forward compatible without
source changes being needed.
