Member Function Documentation

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

virtual

Set the text visible or invisible.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::setTopLeftCorner	(	float	x,
		float	y
	)

virtual

Set the Top left corner of the text in normalized screen coordinates (0..1)

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::setColor	(	float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Set the text's color.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::setText ( const std::string & textString )

virtual

Set the text to display.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::setFont	(	const std::string &	fontFile,
		float	sizeInPoints
	)

virtual

Set the font file and size in points to display the text in.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::setTextBoxWidth ( unsigned int widthInPixels )

virtual

Set the width of the text box in pixels.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::setAlignment ( DtWindowText::TextAlignment alignment )

virtual

Set the alignment mode of the text.

Implements makVrv::DtWindowTextInstance.

virtual bool makVrv::DtOsgWindowTextInstance::visible ( ) const

virtual

Get the text's visibility status.

virtual void makVrv::DtOsgWindowTextInstance::setTransform ( DtMatrix3< double > transform )

virtual

Sets the line's transform matrix, used to update the position and clockwise rotation of the vertices.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::update ( )

virtual

Called on signal_postUpdate; time to update render data.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::setGroup ( int groupId )

virtual

Set this object's group ID for z order.

The higher the Z order the "closer" the element will be drawn to the eye point

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::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.

Implements makVrv::DtWindowTextInstance.

void makVrv::DtOsgWindowTextInstance::createText ( )

Create the text object.

virtual void makVrv::DtOsgWindowTextInstance::setClipBox	(	DtVector2< double >	bottomLeftLocation,
		DtVector2< double >	topRightLocation
	)

protectedvirtual

Set this objects clip box bounds This does not clip text yet.

Implements makVrv::DtWindowTextInstance.

virtual void makVrv::DtOsgWindowTextInstance::slot_releaseResources ( )

protectedvirtual

Destroy the text when the resources are released since it's fonts won't work anymore.

virtual void makVrv::DtOsgWindowTextInstance::slot_channelToBeDestroyed	(	DtChannelManager *	,
		DtChannel *
	)

protectedvirtual

Destroy the text when the channel its being rendered on is going to be destroyed.

virtual void makVrv::DtOsgWindowTextInstance::slot_onViewCreated ( )

protectedvirtual

Recreate the text if needed when a new window is created.

virtual bool makVrv::DtOsgWindowTextInstance::clipTextPosition ( osg::Vec2 position )

protectedvirtual

Check whether the position of this text box is within the clip box.

Checks against top left position.
