Well, what I ended up doing is this:
In QML:
Rectangle
{
signal my_func(variant args)
[...]
MouseArea
{
[...]
onClicked: my_func([1,2,3])
}
}
and in Python:
def stuff(a):
print a
[...]
view.rootObject().my_func.connect(stuff)
which works pretty well for my purposes. It'd be more convenient to have a
variable list of args, but I'm happy enough. =)
Thanks for the ideas!
