part not updated after parameters are modified #24

Hi Lorenz, I have just installed your addon in the very latest version of freecad. I can create cogwheels, but whenever I change any of the parameters, the part is not updated. The only way of making it work is, if I insert a new cogwheel. I don't know if this behaviour is intentional (I don't believe). If not, could you, please, point out, where I have to hack the code to fix this issue? I would really like to have a somewhat prompter visual feedback. Thanks, Zoltán

Hello Zoltà

difficult to say. The updating mechanism was not always the same, so it also depends on the version of FreeCAD.

For this module I used the Part::FeaturePython class and the interface function for the updating mechanism is execute from the python proxy. Maybe there is more responsive function (similar to onChanged) for the viewprovider, but I am not sure.

So sry, I can't help much with this issue. Maybe it's best to ask in the FreeCAD-Forum.

Thanks for the feedback! I am running the latest build of freecad (version 0.18, 16079 git). I will try to read and understand your code, and perhaps, I am able to find out what the problem is. If i succeed, I post the solution here. Otherwise, i might raise the issue in the forum, as you suggested.

I do not have such an issue. Not every change of parameter triggers the recomputation. You have to click into another parameter-field to get the parameter-change applied.

Indeed, seems it's issue of freecad 18.4. It does not update any object when changed. Updated to 19 alpha, everything works. Thank you!
