Detailed Description

Manager of a single window with OpenGL context, used by one or more NIS_InteractiveContext instances. This class inherits V3d_View therefore its instances can be used to display any object that is normally handled by Graphic3d/V3d/AIS classes. Also the standard view operations: Pan, Rotate, Zoom, mouse API, etc. are supported due to this inheritance.

The new services added by this class is the visualisation of NIS_InteractiveObject (i.e., accommodation of NIS_InteractiveContext instances). This visualisation is done by the method MyCallback that is called just before redrawing the scene by Graphic3d/OpenGl drivers.

The View instance can be understood as a collector of several interactive contexts that exist independently (do not interfere) though they output into the same OpenGL context. The contexts are:

AIS_InteractiveContext associated with the view by means of V3d_Viewer instance (the traditional AIS architecture);
1st associated NIS_InteractiveContext
2nd associated NIS_InteractiveContext
...

The list of associated NIS_InteractiveContext can be modified by methods AddContext and RemoveContext.

Handle< NIS_InteractiveObject > NIS_View::Pick	(	const Standard_Integer	theX,
		const Standard_Integer	theY
	)

Interactive selection by mouse click. Selection itself is performed in each Interactive Context attached to this View, accordingto the local parameters (mode, filter) of selection in each context.

Parameters

theX	X coordinate of mouse pointer in the window.
theY	Y coordinate of mouse pointer in the window.

Returns: the selected object picked by the minimal intersection distance among all contexts attached to this View.

Handle< NIS_InteractiveObject > NIS_View::Pick	(	const gp_Ax1 &	theAxis,
		const Standard_Real	theOver,
		const Standard_Boolean	isOnlySel
	)

Interactive selection by mouse click. Selection itself is performed in each Interactive Context attached to this View, accordingto the local parameters (mode, filter) of selection in each context.

Parameters

theAxis	3D axis for objects selection
theOver	Overlap for the selecting axis
isOnlySel	If False, any displayed object can be picked, otherwise only selectable ones.

Returns: the selected object picked by the minimal intersection distance among all contexts attached to this View.

void NIS_View::RemoveContext ( NIS_InteractiveContext * )

protected

Detach an interactive context from this view.

void NIS_View::Select	(	const Standard_Integer	theX,
		const Standard_Integer	theY,
		const Standard_Boolean	isForceMult = `Standard_False`,
		const Standard_Boolean	theRedraw = `Standard_True`
	)

Set or unset the selected (hilighted) state of the object that is under the coordinates theX, theY.

Parameters

theX	X coordinate of the view window
theY	X coordinate of the view window
isForceMult	True if the effect of multi-Selection should be forced (e.g., when Shift is pressed).
theRedraw	True to redraw view automatically (default value).

void NIS_View::Select	(	const Standard_Integer	theXmin,
		const Standard_Integer	theYmin,
		const Standard_Integer	theXmax,
		const Standard_Integer	theYmax,
		const Standard_Boolean	isForceMult = `Standard_False`,
		const Standard_Boolean	isFullyIncluded = `Standard_False`,
		const Standard_Boolean	theRedraw = `Standard_True`
	)

Set or unset the selected (hilighted) state of the objects that are intersected by 2D box in the view

Parameters

theXmin	left X coordinate of the view window
theYmin	lower Y coordinate of the view window
theXmax	right X coordinate of the view window
theYmax	upper Y coordinate of the view window
isForceMult	True if the effect of multi-Selection should be forced (e.g., when Shift is pressed).
isFullyIncluded	True if only those objects are processed that are fully inside the selection rectangle. False if objects fully or partially included in the rectangle are processed.
theRedraw	True to redraw view automatically (default value).

void NIS_View::Select	(	const NCollection_List< gp_XY > &	thePolygon,
		const Standard_Boolean	isForceMult = `Standard_False`,
		const Standard_Boolean	isFullyIncluded = `Standard_False`,
		const Standard_Boolean	theRedraw = `Standard_True`
	)

Set or unset the selected (hilighted) state of the objects that are intersected by 2D polygon in the view

Parameters

thePolygon	defines the vertices of a free-form closed polygon without self-intersections. The last point should not coincide with the first point of the list. Points are interpreted as X and Y integer coordinates of the view window. Any two neighbor points should not be confused.
isForceMult	True if the effect of multi-Selection should be forced (e.g., when Shift is pressed).
isFullyIncluded	True if only those objects are processed that are fully inside the selection rectangle. False if objects fully or partially included in the rectangle are processed.
theRedraw	True to redraw view automatically (default value).

void NIS_View::SetDynHilightSelected ( const Standard_Boolean theHilight = Standard_True )

inline

Indicate whether to hilight selected object dynamically By default dynamic hilight works on all objects independently on its selected/non-selected state. This behaviour differs from the behaviour of AIS interactive context, that doesn't hilight dynamically (on mouse movements) selected objects. In the case both context are used in the same view the behaviour of both context can be made consistent by setting this flag to False

void NIS_View::SetHilightOnTop ( const Standard_Boolean theTop = Standard_True )

inline

Indicate whether to draw hilighted objects on top of all other ones

void NIS_View::SetWindow ( const Handle< Aspect_Window > & theWindow )

Attach the view to the window.
