Returns a list of wires obtained by offsetting the wires of the given
shape by the given amount (outer wire inside, inner wires outside) and
resolving intersections
-removes all soqtviewer references
-create a quarter adaptor class which implements missing functionality
-adopts freecad code to make use of SoRenderManager and changed View3DInventorViewer interface
The arrows were there in the code, but at a certain point, code was written to set the this->imgHeight value programatically, based on
whether it had text or not. As symmetry constraint does not have text the variable failed to initialize. Being zero, it did not pass
the ASSERT in the render function, so it was not rendered.
This includes Werner's fix for improver cast of a SoRayPickAction to SoGLRenderAction:
SbVec2s vp_size = static_cast<SoGLRenderAction*>(action)->getViewportRegion().getWindowSize();
to
SbVec2s vp_size = SoViewportRegionElement::get(state).getWindowSize();
At least sometimes tt is a SoRayPickAction because:
When you move with the mouse over the sketcher (when in edit mode) you enter the method ViewProviderSketch::mouseMove.
Inside there the method getPointOnRay is called to get a picked point underneath the cursor. Inside the latter method
an instance of SoRayPickAction is created to traverse the scene graph. After a long cascade of function calls you
finally enter SoDatumLabel::generatePrimitives(SoAction*).
Do not add a symmetry constraint icon to a group of icons, so that it lies on the line or point providing the symmetry (symmetry axis/point),
as it is more clear to the user which line this is.
Based (and solves) Mantis ticket:
http://www.freecadweb.org/tracker/view.php?id=1643
The ticket refers only to redundant, and ask for deletion.
Two commands are created, one for redundant constraints and other for conflicting constraints.
As usually removing one constraint of the "at least one" is sufficient, the implementation selects the constraints (but does not delete them).
The user therefore easily identify the constraints involved and decide to delete them.
This implementation takes into account the edit->Actsketch that ViewProvidedSketch creates for solving, as it is this instance the one that generates the messages in the Sketcher Taskbar.
No buttons in the toolbar by default (can be added by the user), but an hyperlink in the solver messages which triggers the selection of the appropriate command (conflicting or redundant).
Ex 1: User selects constraints from the list => right click => select "select elements" from the contextual menu => The elements (edges,vertex) involved in the constraint(s) are selected.
Ex 2: User selects (a) constraint(s) => Clicks button in toolbar (if included by the user) => The elements (edges,vertex) involved in the constraint(s) are selected.
Intended as visual aid to see which elements are being affected by a constraint.
