| Affected Issues | 0002171: Several issues when trying to delete an element of a sketch | |||
| Changeset | Sketch: Bug fix: On delete crash with unsuccesful solving ========================================================== Fixes the one reported by JMG here (Thanks!!): http://forum.freecadweb.org/viewtopic.php?f=3&t=11508#p92693 Why? - The newly introduced redrawing policy requires that the solver geometry matches in number the sketchobject geometry. - Most (all) problems with updateColor or getGeometry returning a null pointer are related to an out of sync between UI geometry and SketchObject geometry. General solution: - In other bugs, a missing "solve()" is the problem, once the solver and sketchobject geometries have the same number, an SketchObject::OnChanged triggers a VPSketch::draw (via VPSketch::updateData) which updates the UI geometry to match SketchObject geometry and then the problem does not arise. Particular solution: - In this bug, the problem is not a missing solve, but the fact that the solving was not succesful and did not synchronize the geometries, however triggering a draw() on unsuccessful solving, syncronizes the UI geometry with the SketchObject geometry and the crash is gone. |
