Member Function Documentation

void GlMainWidget::doSelect	(	const int	x,
		const int	y,
		const int	width,
		const int	height,
		std::vector< tlp::node > &	sNode,
		std::vector< tlp::edge > &	sEdge,
		tlp::GlLayer *	layer = NULL
	)

select nodes and edges in a region of the screen

select all nodes and edges lying in the area of the screen of given width and height, and with its upper-left corner at (x,y)

Parameters:

	sNode	filled by the method with the nodes found in the region
	sEdge	filled by the method with the edges found in the region

bool GlMainWidget::doSelect	(	const int	x,
		const int	y,
		tlp::ElementType &	type,
		tlp::node &	,
		tlp::edge &	,
		tlp::GlLayer *	layer = NULL
	)

select a node or edge at a point select either a node or edge at point (x,y)

Parameters:

type

tells what has been found: NODE, EDGE

Returns:

true if something has been found, false otherwise

unsigned char* GlMainWidget::getImage

(

)

Take a snapshot of the Widget

Returns:

an array of dimension width*height*3 char (8bits per color RGB). The pointer has to be freed after (with free, not delete)

bool GlMainWidget::outputEPS	(	int	size,
		int	doSort,
		const char *	filename

		const int	y,
		const int	width,
		const int	height,
		std::vector< tlp::GlEntity * > &	pickedEntities,
		tlp::GlLayer *	layer = NULL
	)

Function to do picking on entities. It just calls selectEntities on the GlScene instance.

bool GlMainWidget::selectGlEntities	(	const int	x,
		const int	y,
		std::vector< tlp::GlEntity * > &	pickedEntities,
		tlp::GlLayer *	layer = NULL
	)

Function to do picking on entities. It just calls selectEntities on the GlScene instance with a small window of twelve pixels.

const

return list of interactor installed on this widget

virtual QImage GlMainWidget::grabFrameBuffer

void GlMainWidget::draw

(

)

[slot]

Draw the graph, the augmented dispaly and the interactors

void GlMainWidget::redraw

(

)

[slot]

That function is given for optimisation purpose. If the hardware enable it, it enables to redraw only the Augmented display and the interactors and not the graph it is really usefull for interactors such as zoom box etc.. Warning, if you change the graph or the porperties of element (Colors, size, etc...) applying that fonction will not display the change, in that case, use the draw function.
