Detailed Description

This class updates vertices for each line added via addLine.

They are stored in a vector of LineStructs which contain the verts and stipple pattern. You can update the lines after they have been added without deleting them using updateLine. This means that they do not flash on screen. Please call setLineCount before adding lines. updateLine will adjust the number of DtSegmentedLines this class has to match myLineCount.

Member Function Documentation

virtual void makVrv::DtOsgWindowLineGroupInstance::setLineCount ( unsigned int count )

virtual

Set the number of Lines that this group will have Should be set before addLine is called.

virtual void makVrv::DtOsgWindowLineGroupInstance::addLine	(	float	lineWidth,
		unsigned int	stipplePattern,
		float	xVertex0,
		float	yVertex0,
		float	xVertex1,
		float	yVertex1
	)

virtual

Add an Line to the specified in params Calls createLineStruct.

virtual void makVrv::DtOsgWindowLineGroupInstance::updateLine	(	unsigned int	index,
		float	lineWidth,
		unsigned int	stipplePattern,
		float	xVertex0,
		float	yVertex0,
		float	xVertex1,
		float	yVertex1
	)

virtual

Update the Line at in param index with in parma specs.

The reason index is passed in is because we need to know which Line to update. You cannot just delete all the pointers and recreate once all the updateLine calls arrive ( indexNumber = myLineCount ), because the Lines will flash on screen!!

virtual void makVrv::DtOsgWindowLineGroupInstance::setVisible ( bool isVisible )

virtual

Set all of the Lines to visible or invisible.

Reimplemented from makVrv::DtOsgWindowLineInstance.

virtual void makVrv::DtOsgWindowLineGroupInstance::setChannelOverlay	(	std::string	displayName,
		std::string	windowName,
		std::string	channelName
	)

virtual

By default window objects are placed on the RemoteDisplayWorldOverlay, which is rendered on all channels that have the "showRemoteGraphics" channel keyword.

If a user wishes to draw a specific window object on a specific channel, use this method. This does not work for remote displays.

Reimplemented from makVrv::DtOsgWindowLineInstance.

virtual void makVrv::DtOsgWindowLineGroupInstance::updateGeometry ( )

protectedvirtual

Generate the vertices of the graphic polygon that approximates the Line Loops through myLines updating vertices on either the filled polygons or lines.

Called by DtOsgWindowLineInstance::update()

Reimplemented from makVrv::DtOsgWindowLineInstance.

virtual void makVrv::DtOsgWindowLineGroupInstance::deleteAllLines ( )

protectedvirtual

Delete all the pointers and structs in myLines.

virtual DtSegmentedLine* makVrv::DtOsgWindowLineGroupInstance::createAdditionalLine ( )

protectedvirtual

Create a line.
