Dear mailing-list members, first I'd like to introduce myself. I'm Thomas Pietrowski and I'm working on a plugin, which shall enable Windows Automation for Cura. Cura is a slicing application for 3D-printers written in Python and I would like to control this application over COM.
The last weeks I worked hard on getting something working and managed to do function calls and get values of some attributes. However, something I still don't manage to do is receiving signals. While slicing there is the progress sent within Cura as a Qt signal. This is one of the Qt signals, which I would turn into a COM event. So whenever the progress changes, the widget in the GUI will get updated, as well as the event will be sent over COM. However, this is what I have in mind. What I still can't manage to get working is executing a "DoEvent()" function, which emits an signal and receiving the "OnEvent()" in my handler. Whenever I want to DispatchWithEvents() or do a WithEvents() on a running client session, I always get an error that the client can't manage to automise something and I shall use makepy. After using makepy I still get the same issue. So I guess I made something wrong while writing my IDL and/or COM server. Therefore my client is not able to get all the info it needs. All source are available on GitHub: https://github.com/thopiekar/CuraInterfacePlugin/tree/master-sending-and-receiving-signals (here: "master-sending-and-receiving-signals" branch) Do you see any mistakes I made? Alternatively, do you have a working server/client example with working events? This would probably give me an kickstart :) With kind regards - Thomas Karl Pietrowski
