Detailed Description

Renderwidget is a QWidget containing all the necessary UI properties for starting the render thread and displaying the render thread's results in the application window.

Constructor & Destructor Documentation

RenderWidget::RenderWidget	(	QWidget *	parent,
		Graph *	g
	)

Renderwidget constructor.

Parameters

parent	pointer to the application window
g	pointer to the graph

Member Function Documentation

void RenderWidget::paintEvent ( QPaintEvent *  event )

protected

Reimplementation of Qt's UI paint event.

void RenderWidget::resizeEvent ( QResizeEvent *  event )

protected

Reimplementation of Qt's UI resize event.

void RenderWidget::setEdgeProperties ( QColor  lineColor, double  lineWidth  )

slot

Setter for the visual properties of the graph's edges

Parameters

lineColor	color of the edges' lines
lineWidth	width of the edges' lines

void RenderWidget::setNodeProperties ( double  radius, QColor  fillColor, QColor  lineColor, double  lineWidth  )

slot

Setter for the visual properties of the graph's nodes

Parameters

radius	nodes' radius
fillColor	color the node circle is filled with
lineColor	color of the nodes' outlines
lineWidth	width of the nodes' outlines

void RenderWidget::updatePixmap ( const QImage &  image )

protectedslot

Slot that is called from the RenderThread when it has finished the render process and is ready to deliver a result image.

Parameters

image

the updated rendered image

void RenderWidget::useBackgroundImage

(

QString

path

)

Sets the background image to a new image specified by the image path. Implementation allows for .png, .jpg and .svg.

Parameters

path	Path to the new background image.
