* Undo can not circumvented, if the programmer do not open a transaction the changes will appended to the open one or a anonymous transaction will be created automatic. yes it's minor, but in this case transaction won't receive a special name... and in general it's not good to call both API's, but ...

I think it may be related to the fact that I am returning by reference a local variable (yes, for a normal variable there is a memory leak because the variable is destroyed upon leaving the function, so the reference points to an address with invalid/destroyed data), but according to my knowledge o...

I think if you change the order of features in the vector returned by DocumentObject::getOutList(), you can control the order of children in the DAG view. This might be a good temporary solution. Hmm... this one doesn't feel right... Firstly, it's not a virtual and IMHO it's not intended to be, bec...

Just wondering about future use cases... Is the DAGView a general implementation and may display arbitrary graph Data? or at least arbitrary set of ViewProviders/DocumentObjects? or is it nailed to display App::Document content? No, Its pretty rigid in it's present form. What are you thinking about...

The phpbb site seems down. Can you get the bbcode that's needed? I can add it easily. Works for me...

Ah, I see.. The old interface is used mainly by the Group objects in FreeCAD. The new mimic will be broader but, as you saw already, needs more love. I stopped it till I get more of the basic Assembly stuff done to really use it.. Also note that currently both of modes are slightly broken: the old ...

For a drag target its important to know the position of the drop and the mouse button and keys pressed. Imagine you drag a Screw out of a catalog view and drop it on a 3D object. There you maybe want to check of you hit a hole-feature and do the right positioning. Especially in Assembly I want to u...

According to this you'd need to add a custom bb code...

I've already fixed that for Origin's planes in my branch if you wonder... I'm unsure now if we should to do that for non-PartDesign sketches, but it will be a single line fix and can be discussed later... Is there a risk to break file compatibility here? File designed in current assembly branch won'...
