I can't imagine how such behavior could be possible. I don't think that this can happen unless there are changes in the sketcher during the last year that I am not aware of.

yes, your diagnosis seems right to me, good catch.

If all constraints disappear (also those not involving external geometries) then this is a bug. They are not actually deleted, they are just hidden/disabled. This was a quirk for solving some issues with undoing/redoing. As far as I remember, the constraints list in a geometry is aware of the geomet...

This is the problem that I assumed. Actually we had discussed about the positioning question like 2 years ago. Unfortunately we didn't come with a concrete common strategy about how to deal with the placement property. So that each of us had a different opinion/strategy in his mind. Myself, I used t...

could someone post a screenshot showing the problem please.

this turned into a very interesting discussion that I am learning a lot from and the test code is also very useful. I just have a comment to the philosophical part of it: In the MS/Windows development style the developer/company has the responsibility/freedom to compile and package all components an...

no, I understood what you said the first time. I mean also after doing further operations, still I cannot see any empty transactions in between in the undo list. What I do to test it is : delete a geometry A add another geometry B undo once (removes geometry B) undo again (adds the deleted geometry A)

hm I cannot confirm this, it works fine with closing the transaction twice. No redundant transaction is included in the undo list.

I have been fighting Windows bugs for most of December, and wow, I've seen the dark side of Windows development with regards to working outside Microsoft's preferred tool set. sorry triplus, this is a different case, Thomas from OpenShot refers to developping in Windows with MinGW, not with VS. Jür...

ok, I just tried to just close the transaction twice, which fits better my case and it works. So I don't need to change anything in a very central command like StdCmdDelete.
