Re: PathGui: ViewProviderPath visual enhancement #625

This does break the regular Path operations. I'm getting this error trying to create a new contour or other operation. Should be an easy fix but might be needed in a few places. : File "<string>", line 6, in <module> File "/home/brad/FC/Mod/Path/PathScripts/PathLoadTool.py", line 104, in __init__ v...

Era defining gadget, made in FreeCAD!

This is my precious that I've been working for more than two years! When I said 'Era defining', I ought to add 'I hope' somewhere, but I think that goes without saying. And I am not joking either. You know, when you talk about computing device, we have those room size dinosaur era, then comes the PC...

Re: KiCad and FreeCAD collaboration!

After almost one year and half, my FreeCAD scripted and parametric 3D models for electronic parts has been merged in the official KiCad 3D library repo! :D Wow, I really need to spend more time reading than coding all day. Look what I've missed. I've forked your repo long time ago, and the StepUp s...

Re: Optics in FreeCAD

Got an image of some stuff through the lens! On AMD Radeon 7700 and with regular mouse, CADRays is behaving much much better, and makes a nice rendering faster. :o That's very impressive! I actually saw this post long time ago, and was hoping at that time I may some day venture into optics. Unfortu...

Re: #619 Made TreeView stable

visit each children recursively (that's factorial n! maybe?) n! !?? If so, it's awful, since factorial of just 13 is already over 1G. And a factorial of 20 will take about 100 years to traverse. Oops, I mean 1+2+3..+n, not multiple, n(n+1)/2. This is the case where all child items are loaded before...

Re: #619 Made TreeView stable

:lol: Maybe it can be made faster by going the other way around? i.e. when adding an object as child of something, and withdrawing it from root, look up the ultimate parent of something and check if it is the child being added? This way, the performance penalty is proportional to depth of tree, whic...

Re: #619 Made TreeView stable

It may, as it looks like tree update is fired for every change to a property... So maybe just leave it alone for now? The cyclic check only happens when a free item (i.e. an item at document root) is newly claimed, which already has children. The check needs to visit all its children. That's the on...

Re: #619 Made TreeView stable

I'll have a look at what's going on, because I now have a feeling it's not your code that hangs. It is kinda of. It actually hangs inside Qt::TreeWidgetItem.addChild. They don't bother checking cyclic reference either. And for a good reason, as it may be a potentially expensive operation. I added t...
