virtual void trikControl::DisplayInterface::addLabel	(	const QString &	text,
		int	x,
		int	y
	)

pure virtualslot

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.

virtual void trikControl::DisplayInterface::clear ( )

pure virtualslot

Clear everything painted with this object.

virtual void trikControl::DisplayInterface::drawArc	(	int	x,
		int	y,
		int	width,
		int	height,
		int	startAngle,
		int	spanAngle
	)

pure virtualslot

Draw arc on the widget without redrawing it 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.

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

pure virtualslot

Draw ellipse without redrawing display.

Parameters

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

virtual void trikControl::DisplayInterface::drawLine	(	int	x1,
		int	y1,
		int	x2,
		int	y2
	)

pure virtualslot

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.

virtual void trikControl::DisplayInterface::drawPoint	(	int	x,
		int	y
	)

pure virtualslot

Draw point on the widget without redrawing it.

Parameters

x	- x coordinate.
y	- y coordinate.

virtual void trikControl::DisplayInterface::drawRect	(	int	x,

Parameters

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

virtual DisplayWidgetInterface& trikControl::DisplayInterface::graphicsWidget ( )

pure virtual

Returns widget on which everything is drawn.

Implemented in trikControl::Display.

virtual void trikControl::DisplayInterface::hide ( )

pure virtualslot

Hides and clears widget on which everything is drawn.

virtual void trikControl::DisplayInterface::redraw ( )

Set painter width.

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

pure virtualslot

Shows given image on display.

Scales from to fullscreen

Parameters

array	- pixel data (depends on format)
width	- image width
height	- image height
format	- "rgb32" for packed xRGB32 (pixel per int32), "grayscale8" for grayscale 8bit (int per pixel), "rgb888" for 3 ints per pixel (R,G,B – 8bits each)

virtual void trikControl::DisplayInterface::showImage ( const QString & fileName )

pure virtualslot

Shows given image on a display.

Parameters

fileName - file name (with path) of an image to show. Refer to Qt documentation for supported formats, but .jpg, .png, .bmp, .gif are supported.
