[PySide] What is being used instead of @pyqtSignature?

[Mark Summerfield]

Hi,

The purpose of the @pyqtSignature decorator is to help the uic-generated
file's setupUi() method's connectSlotsByName() call be able to correctly
connect methods that are reimplementations of slots that have two or
more overloads.

For example the QPushButton.clicked() signal has one overload that has
no argument and another that has a bool (to indicate its toggle state).

So whereas in PyQt I'd write:

@pyqtSignature("")
def on_button_clicked(self):
# handle the non-toggle case

@pyqtSignature("bool")
def on_button_clicked(self):
# handle the toggle case separately

how would I do it in PySide?

(I know my example doesn't make sense; it is just to illustrate the
question.)

Thanks!

On PySide connectSlotsByName() only works with slots registered into
metaobject, so you have to decorate your on_x_y methods with @Slot decorator,
in the @Slot decorator you put the method signature, this also should work
with PyQt.
