Member Function Documentation

void GuiWorker::addLabel	(	const QString &	text,
		int	x,
		int	y
	)

slot

Add a label to the specific position of the screen without redrawing it.

If there already is a label in these coordinates, its contents will be updated.

Parameters

text	- label text.
x	- label x coordinate.
y	- label y coordinate.

void GuiWorker::clear ( )

slot

Clear everything painted with this object.

void GuiWorker::drawArc	(	int	x,
		int	y,
		int	width,
		int	height,
		int	startAngle,
		int	spanAngle
	)

slot

Draw arc on the widget without redrawing it.

Parameters

x	- x coordinate.
y	- y coordinate.
width	- width rect forming an arc.
height	- height rect forming an arc.
startAngle	- start angle.
spanAngle	- end andle.

void GuiWorker::drawEllipse	(	int	x,
		int	y,
		int	width,
		int	height,
		bool	filled = `false`
	)

slot

Draw ellipse without redrawing the screen.

Parameters

x	- x coordinate.
y	- y coordinate.
width	- width of ellipse.
height	- height of ellipse.

void GuiWorker::drawLine	(	int	x1,
		int	y1,
		int	x2,
		int	y2
	)

slot

Draw line on the widget without redrawing it.

Parameters

x1	- first point's x coordinate.
y1	- first point's y coordinate.
x2	- second point's x coordinate.
y2	- second point's y coordinate.

void GuiWorker::drawPoint	(	int	x,
		int	y
	)

slot

Draw point on the widget without redrawing it.

Parameters

x	- x coordinate.
y	- y coordinate.

void GuiWorker::drawRect	(	int	x,
		int	y,
		int	width,
		int	height,
		bool	filled = `false`
	)

slot

Draw rect on the widget without redrawing it.

Parameters

x	- x coordinate.
y	- y coordinate.
width	- rect's width.
height	- rect's height.

DisplayWidgetInterface & GuiWorker::graphicsWidget ( )

Returns a widget on which everything is drawn.

void GuiWorker::hide ( )

slot

Hides image widget.

void GuiWorker::init ( )

slot

Initializes widget. Shall be called when widget is moved to correct thread. Not supposed to be called from .qts.

void GuiWorker::redraw ( )

slot

Updates painted picture on the robot`s screen.

Warning: This operation is pretty slow, so it shouldn`t be called without need.

void GuiWorker::removeLabels ( )

slot

Remove all labels from the screen and redraws it.

void GuiWorker::reset ( )

slot

Returns a display in a blank state.

void GuiWorker::setBackground ( const QString & color )

Parameters

color - color of a background.

void GuiWorker::setPainterColor ( const QString & color )

slot

Set painter color.

void GuiWorker::setPainterWidth ( int penWidth )

slot

Set painter width.

void GuiWorker::show	(	const QVector< int32_t > &	array,
		int	width,
		int	height,
		const QString &	format
	)

slot

Shows image from array data according to format. Image is scaled to fill the screen.

void GuiWorker::showImage ( const QString & fileName )

slot

Shows image with given filename on display.

Image is scaled to fill the screen and is cached on first read for better performance.
