I need to move a grip indirectly through an MFC slider. I’ve followed @dale’s SampleMoveGrips to do this.
The problem is that it calls
CRhinoObjectGrips::NewObject() for every event of the slider being dragged, while
CRhinoObjectGrips::Draw() is never called.
I’d like to have this mechanism:
- Slider being dragged:
CRhinoObjectGrips::Draw()is called every time. No
CRhinoObjectGrips::NewObject(), no data added to Rhino’s undo stack.
- Slider dropped:
CRhinoObjectGrips::NewObject()is called once. This final configuration is stored in Rhino’s undo stack.
My reasons to do this are memory related: handling pretty big meshes through custom grips, I cannot store undo data when dragging UI controls except once dropped. Also, triggering
CRhinoObjectGrips::Draw() would be great.
Any idea on this? There’s
CRhinoGripObject::DragGrips() but it calls
CRhinoGripObject::MoveGrips() which does what I referred in the above sample.
I know display conduits might be a solution but I want to know if it’s possible through grips (because of their tremendous capabilities like selecting grips, transforms, etc).
Thank you very much,
