Detailed Description

These are the graphis routines usable with pyQDrawWidget()

Function Documentation

int gBeginDraw	(	PARAM *	p,
		int	id
	)

Call this function before you start drawing the widget.

int gBox	(	PARAM *	p,
		int	x,
		int	y,
		int	w,
		int	h
	)

Draws a rectangle frame. Later you can use it's coordinates to draw xAxis, yAxiy and ryAxis.

int gBoxWithText	(	PARAM *	p,
		int	x,
		int	y,
		int	w,
		int	h,
		int	fontsize,
		const char *	xlabel,
		const char *	ylabel,
		const char *	rylabel
	)

This is a convenience function that draws a box and write the xlabel ylabel and rylabel
in the given font.
If one of the text parameters is NULL no text is drawn for that item.

int gBufferedLine ( PARAM * p )

Draw a line in a Axis.
See pvXYAllocate
See also Linestyle.

int gCloseFile ( )

Call this function after you have written graphical commands to a file.

int gComment	(	PARAM *	p,
		const char *	comment
	)

Write a comment in the metafile

int gDrawArc	(	PARAM *	p,
		int	x,
		int	y,
		int	w,
		int	h,
		int	start_angle,
		int	angle_length
	)

Draw an arc. For circle write:
  gDrawArc(p,x-radius/2,y-radius/2,radius/2,radius/2,0,360);

int gDrawPie	(	PARAM *	p,
		int	x,
		int	y,
		int	w,
		int	h,
		int	start_angle,
		int	angle_length
	)

Draw an pie (filled part of a circle) . For filled circle write:
  gDrawArc(p,x-radius/2,y-radius/2,radius/2,radius/2,0,360);

int gDrawPolygon	(	PARAM *	p,
		int *	x,
		int *	y,
		int	n
	)

x,y is an array with the edge points.
n is the number of points

int gEndDraw ( PARAM * p )

Call this function when you are finished with drawing.

int gLine	(	PARAM *	p,
		float *	x,
		float *	y,
		int	n
	)

Draw a line in a Axis n=number of values in x,y.
See also Linestyle.

int gLineTo	(	PARAM *	p,
		int	x,
		int	y
	)

Draw a line from the actual position to x,y.

int gMoveTo	(	PARAM *	p,
		int	x,
		int	y
	)

Move to x,y.

int gPlaySVG	(	PARAM *	p,
		const char *	filename
	)

Play SVG file
You have to download the file first using:
int pvDownloadFile(PARAM *p, const char *filename);

Attention:
This is a deprecated function.
It only works with the Qt3 version of pvbrowser client.
Now use rlSvgAnumator from rllib.

int gRect	(	PARAM *	p,
		int	x,
		int	y,
		int	w,
		int	h
	)

Draws a filled rectangle.

int gRightYAxis	(	PARAM *	p,
		float	start,
		float	delta,
		float	end,
		int	draw
	)

Draw a Axis on the right side of the diagram.
It starts with start in steps of delta until end is reached.

int gRotate	(	PARAM *	p,
		float	angle
	)

Rotate the graphic
Rotates the coordinate system angle degrees counterclockwise.

int gScale	(	PARAM *	p,
		float	sx,
		float	sy
	)

Scale the graphic

int gSetColor	(	PARAM *	p,
		int	r,
		int	g,
		int	b
	)

Set the drawing color.

int gSetFloatFormat	(	PARAM *	p,
		const char *	text
	)

Set the format in which the Axis is drawn.
default: "%f"
For example set
"%5.2f"
if you want two digits behind the .

int gSetFont	(	PARAM *	p,
		const char *	family,
		int	size,
		int	weight,
		int	italic
	)

Set a font. For the availabe fonts see Definitions (Events, Fonts, Colors ...)

int gSetLinestyle	(	PARAM *	p,
		int	style
	)

Set the linestyle of a line in the Axis. You can draw a simple line or a line with centered symbols.

int gSetStyle	(	PARAM *	p,
		int	style
	)

style = PenStyle.

int gSetWidth	(	PARAM *	p,
		int	w
	)

Set the line width

int gSocketPlaySVG	(	PARAM *	p,
		const char *	svgstring
	)

Play SVG string over the socket

Attention:
This is a deprecated function.
It only works with the Qt3 version of pvbrowser client.
Now use rlSvgAnumator from rllib.

int gText	(	PARAM *	p,
		int	x,
		int	y,
		const char *	text,
		int	alignment
	)

Draw a text at x,y.
For alignment see Definitions (Events, Fonts, Colors ...)

int gTextInAxis	(	PARAM *	p,
		float	x,
		float	y,
		const char *	text,
		int	alignment

default 1

int pvSetZoomX	(	PARAM *	p,
		int	id,
		float	zoom
	)

Zoom the image in X direction. (default: zoom=1.0)
If zoom < 0.0 then keep aspect ratio, factor = |zoom|.

int pvSetZoomY	(	PARAM *	p,
