35 DEFINE_STANDARD_HANDLE (AIS_Manipulator, AIS_InteractiveObject)
37 //! Interactive object class to manipulate local transformation of another interactive
38 //! object or a group of objects via mouse.
39 //! It manages three types of manipulations in 3D space:
40 //! - translation through axis
41 //! - scaling within axis
42 //! - rotation around axis
43 //! To enable one of this modes, selection mode (from 1 to 3) is to be activated.
44 //! There are three orthogonal transformation axes defined by position property of
45 //! the manipulator. Particular transformation mode can be disabled for each
46 //! of the axes or all of them. Furthermore each of the axes can be hidden or
48 //! The following steps demonstrate how to attach, configure and use manipulator
49 //! for an interactive object:
50 //! Step 1. Create manipulator object and adjust it appearance:
52 //! Handle(AIS_Manipulator) aManipulator = new AIS_Manipulator();
53 //! aManipulator->SetPart (0, AIS_Manipulator::Scaling, Standard_False);
54 //! aManipulator->SetPart (1, AIS_Manipulator::Rotation, Standard_False);
55 //! // Attach manipulator to already displayed object and manage manipulation modes
56 //! aManipulator->AttachToObject (anAISObject);
57 //! aManipulator->EnableMode (AIS_Manipulator::Translation);
58 //! aManipulator->EnableMode (AIS_Manipulator::Rotation);
59 //! aManipulator->EnableMode (AIS_Manipulator::Scaling);
61 //! Note that you can enable only one manipulation mode but have all visual parts displayed.
62 //! This code allows you to view manipulator and select its manipulation parts.
63 //! Note that manipulator activates mode on part selection.
64 //! If this mode is activated, no selection will be performed for manipulator.
65 //! It can be activated with highlighting. To enable this:
67 //! aManipulator->SetModeActivationOnDetection (Standard_True);
69 //! Step 2. To perform transformation of object use next code in your event processing chain:
71 //! // catch mouse button down event
72 //! if (aManipulator->HasActiveMode())
74 //! aManipulator->StartTransform (anXPix, anYPix, aV3dView);
77 //! // or track mouse move event
78 //! if (aManipulator->HasActiveMode())
80 //! aManipulator->Transform (anXPix, anYPix, aV3dView);
81 //! aV3dView->Redraw();
84 //! // or catch mouse button up event (apply) or escape event (cancel)
85 //! aManipulator->StopTransform(/*Standard_Boolean toApply*/);
87 //! Step 3. To deactivate current manipulation mode use:
88 //! @code aManipulator->DeactivateCurrentMode();
90 //! Step 4. To detach manipulator from object use:
92 //! aManipulator->Detach();
94 //! The last method erases manipulator object.
96 //! On construction an instance of AIS_Manipulator object is bound to Graphic3d_ZLayerId_Topmost layer,
97 //! so make sure to call for your AIS_InteractiveContext the method MainSelector()->SetPickClosest (Standard_False)
98 //! otherwise you may notice issues with activation of modes.
