Hello list,
I've been unsuccessfully trying to use an animation proxy for an
NSWindow instance using Python:
For example:
----
def fadeOut(self, window):
window.animator().setAlphaValue_(0.0)
----
causes my application to crash.
Bypassing the proxy, however works:
----
def fadeOut(self, window):
window.setAlphaValue_(0.0)
----
Interestingly, if I invoke the setAlphaValue method on the proxy using
the performSelector method, it works:
----
def fadeOut(self, window):
windowProxy = window.animator()
windowProxy.performSelector_('setAlphaValue:')
----
The above code will cause the window to animate a fade out to blank,
which is expected because I'm not passing in any parameters and it is
assuming an alpha value of nil or 0. (Note that I am aware of
performSelector_withObject_, but it did not work as expected, probably
because the input parameter is a double and not an NSObject).
Question: Is all of this expected behaviour? If so, what is the best
practice for calling methods on proxy objects like this in Python?
Thanks very much in advance!
Regards,
Mani
