Detailed Description

This class implements conveyor nodes performing selections.

Remarks

Behavior of this node depends on the selection mode. If the mode is "fence", the points specify polyline vertices. If the mode is "crossing" or "window", the points specify polygon vertices. If exactly two points are specified, the polygon is rectangle, with the points opposite vertices.

For any input primitive, this node performs the following actions:

1. It checks for primitive intersections with the polygon border.
2. If intersections are found, the node MARKS current drawable, and stops to handle the primitive.
3. If the mode is mode is "crossing", and the primitive is inside the polygon, the node MARKS the current drawable and stops to handle the primitive.
4. If the mode is "window", and primitive is outside the polygon, the node MARKS the current drawable and stops to handle the primitive.

To MARK the current drawable is means to currentDrawableDesc()->markBySelection(true). If the drawable is neither a compound object nor uses nesting, means currentDrawableDesc()->markToSkip(true).

This conveyor node is used for implementation OdGsBaseVectorizeView::select() and does not produce any output.

get()

virtual void OdGiSelectProc::get ( OdGePoint2dArray & points, OdGsView::SelectionMode & mode )

pure virtual

Retrieves the boundary that forms selection area, selection mode.

Parameters

points	[out] Array of points that form the selection area.
mode	[out] Selection mode.

ODRX_DECLARE_MEMBERS()

OdGiSelectProc::ODRX_DECLARE_MEMBERS

(

OdGiSelectProc

)

set()

virtual void OdGiSelectProc::set ( const OdGePoint2d * pPoints, OdUInt32 nPoints, OdGsView::SelectionMode mode, OdGsSelectionReactor * pReactor )

pure virtual

Sets the boundary that forms selection area, selection mode and reactor.

Parameters

pPoints	[in] Pointer to an array of points that form selection area.
nPoints	[in] Number of points in array.
mode	[in] Selection mode.
pReactor	[in] Pointer to the selection reactor.

supportsSubentitySelection()

static bool OdGiSelectProc::supportsSubentitySelection ( const OdGiViewport * pView, OdGsView::SelectionMode mode, OdGsSelectionReactor * pReactor )

static

Checks whether selection reactor and selection mode support subentity selection.

Parameters

pView	[in] Pointer to the graphic view.
mode	[in] Selection mode. Currently not used.
pReactor	[in] Pointer to the selection reactor.

Returns

True if subentity selection is supported for the selection reactor, false otherwise.
