Detailed Description

See also

Class Osnap, Class IOsnapManager, Class GraphicsWindow, Class IPoint3.

Description:

This class is used for drawing Osnap markers in the viewports. The marker is drawn as a polyline. The class maintains a cache of the points for the polyline. There are constructors used to initialize the cache and a display() method to draw the marker in the specified viewport.

The Osnap class must implement the GetMarkers() method which typically returns pointers to these static instances.

Constructor & Destructor Documentation

OsnapMarker() [1/3]

CoreExport OsnapMarker

(

)

Remarks

Constructor. The cache of marker points is set to NULL and the number of points is set to 0.

~OsnapMarker()

CoreExport ~OsnapMarker

(

)

Remarks

Destructor. If any marker points have been allocated for the cache they are freed.

OsnapMarker() [2/3]

CoreExport OsnapMarker	(	int	n,
		IPoint3 *	ppt,
		int *	pes
	)

Remarks

Constructor. This initializes the cache with the points and edge flags passed.

Parameters:

int n

The number of points in the marker polyline.

IPoint3 *ppt

The array of points for the polyline.

int *pes

The edge state array. This is an array that indicates if the 'n-th' edge is one of three state:

GW_EDGE_SKIP

Nonexistent - totally invisible.

GW_EDGE_VIS

Exists and is solid.

GW_EDGE_INVIS

Exists and is hidden - shown as a dotted line.

You may pass NULL for this array and the method will assume that the edges are all solid.

OsnapMarker() [3/3]

CoreExport OsnapMarker

(

const OsnapMarker &

om

)

Remarks

Constructor. The marker data is initialzed from the OsnapMarker passed.

Parameters:

const OsnapMarker& om

The settings are copied from this OsnapMarker.

Member Function Documentation

operator=()

CoreExport OsnapMarker& operator=

(

const OsnapMarker &

om

)

Remarks

Assignment operator.

Parameters:

const OsnapMarker& om

The OsnapMarker to assign.

display()

void display	(	IPoint3	xyz,
		int	markersize,
		GraphicsWindow *	gw
	)

Remarks

This is method is used internally to display the marker cache at the specified size in the specified viewport. Plugin developers need not call this method.
