hasObject does search recursive only in groups, but a body is not a group. Hence for sketches within a body this will always return false. Annother logic must be used to detect sketches in bodies.
validateSketch was faulty: as every sketch is valid (non is removed) it could happen that the returned number was >0 but the iterator firstValidSketch was NULL nontheless. The routine needed to be udated to make snese and the usage in prepareSketchbased together with it.
With the new setup object signals it may happen that a document object claims children but has no property changed after the viewprodivers creation. This scenario is not supportet up to now as the scene graph children are only set when the object changes.
It is possible that a newly reated document object already claims other existing objects. The tree needs to be recomputed in this case.
This happens for example for the origin, which creates its planes and axis first and claims them before its own viewprovider is created.
DocumentObject::testIfLinkDAGCompatible: return true if link can be
created (no cycles will be made). False if the link will cause a
circular dependency and break recomputes.
On datum creation it is better to ask the user on OK than on tool activation, as he might hit cancel (and then the created references are till there) or even more important, he could add additional external references within the dialog. The disadvantae is that if the user sets "cross reference" ge gets asked again every time he opens and leaves the dialog.
- Make Datums colorable and transparent
- Change default datums color to yellow and transparency to 60%
- Rework Lines and Points datum view provider
- Add ViewProviderDatum::defaultBoundBox()
The new selection model is not usable for the OriginFeature's view
provider due to from one side it doesn't really have any subfeatures, so
it won't be really needed, and on the other side we will have to use
SoFCSelection because in that case it isn't possible to implement
highlighting in any sane way (unless we will reimplement drawing ourselfs).
