Faster way of checking if dialog has closed?
-
Hello
I'm trying to understand a way of checking if dialog has closed(Preferences)?Script opens:
c4d.PrefsLib_OpenDialog(c4d.FORMAT_ABCEXPORT)
and wait until user closes Preferences -

I am slightly confused, because your title implies that you have found a way to check if a
GeDialog
has closed, that has not been implemented by yourself. At least to my knowledge there is no official way to do this and I also could not think of a hacky way to do it. Would you mind sharing your workaround?On a totally unrelated topic: The function name
PrefsLib_OpenDialog
makes me feel itchy.Cheers,

Hi,
thanks for sharing, okay that is so hacky, that I did not even consider it I still have no solution for you, but would like to point out that your solution is rather risky.
- When the user has docked the Preferences dialog there will be no window handle for it. Which might leave your code in an undefined state, depending on your implementation.
- I assume you are just using the window title as an identifier and not the actual handle? The name Preferences is not that uncommon and you might run into problems when the user is running an app that also spawns a window that title.
Also making Python non-OS-agnostic for such a minor functionality does not seem to be worth it in my opinion.

Hello
After analyzing data, found(u'Preferences', <maxon.interface.LP_c_long object at 0x0000024CCDF7A848>)
But i can't find LP_c_long in maxon.interface or interface in *resource\modules\python\libs\python27\maxon*

I use silly method to seek in string
if str(data)[0:6] == '<maxon': print True
Or how to get data by maxon.interface methods

That is rather vague. But generally speaking most parts of the
maxon
API are read-only, undocumented and a little bit on the buggy side when it comes to Python. I would not bother trying to get anything meaningful out of it.If you are really hell-bent on doing this, the best approach IMHO would be not open Cinema's Preferences dialog, but a dialog that wraps around the preferences plugin node. Here you could easily implement a callback for an
on_close
event. This would also avoid the situation that the user has the preferences docked in his GUI and therefor will never close it. But it comes with its own problems. See the attached script manager script for a sketch on how you could implement this.Cheers,

@maxon: The Python docs on
DescriptionCustomGui.SetObject(self, op)
say thatop
has to be of typeBaseObject
. I am not sure if this intended, but I would assume the required type to actually beBaseList2D

LP_c_long
Long story short it's a pointer http://makble.com/the-story-of-lpclong, and I think the method provided by Zipit is the best one, since as he said there is no way to control the behavior of an external (from your plugin) GeDialog.
