Detailed Description

2D text drawing class. Uses pango with cairo.

A position can be set using setPosition() (see there). The text is then drawn with the properties in TextTraits accessible by traits().

Bug:

FIXME: rel_x|y funktioniert nicht mit markup Text!

Member Function Documentation

addToPath()

void goPlot::Object2DText::addToPath

(

)

Used to find out borders with getBorderHint ()

setPosition()

void goPlot::Object2DText::setPosition	(	goPlot::real	x,
		goPlot::real	y,
		goPlot::real	rel_dx = 0.0,
		goPlot::real	rel_dy = 0.0
	)

Sets position of text.

Sets the text position at (x,y) and moves the text in (w * rel_dx, h * rel_dy) direction, where w and h are the text's width and height, respectively. You can use this e.g. for alignment. Note that the motion is done before transformations, so it gets transformed.

Parameters

x	x position.
y	y position.
rel_dx	relative movement in x direction
rel_dy	relative movement in y direction
