35DEFINE_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
47//! made visible.
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:
51//! @code
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);
60//! @endcode
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:
66//! @code
67//! aManipulator->SetModeActivationOnDetection (Standard_True);
68//! @endcode
69//! Step 2. To perform transformation of object use next code in your event processing chain:
70//! @code
71//! // catch mouse button down event
72//! if (aManipulator->HasActiveMode())
73//! {
74//! aManipulator->StartTransform (anXPix, anYPix, aV3dView);
75//! }
76//! ...
77//! // or track mouse move event
78//! if (aManipulator->HasActiveMode())
79//! {
80//! aManipulator->Transform (anXPix, anYPix, aV3dView);
81//! aV3dView->Redraw();
82//! }
83//! ...
84//! // or catch mouse button up event (apply) or escape event (cancel)
85//! aManipulator->StopTransform(/*Standard_Boolean toApply*/);
86//! @endcode
87//! Step 3. To deactivate current manipulation mode use:
88//! @code aManipulator->DeactivateCurrentMode();
89//! @endcode
90//! Step 4. To detach manipulator from object use:
91//! @code
92//! aManipulator->Detach();
93//! @endcode
94//! The last method erases manipulator object.
95//! @warning
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.
