Detailed Description

base class for all derived classes that do not draw anything

This class finalizes draw() with no drawing actions and and getSizeInternal(), which return a size 0.

◆ draw()

virtual double JKQTMathTextNonDrawingBaseNode::draw	(	QPainter &	painter,
		double	x,
		double	y,
		JKQTMathTextEnvironment	currentEv
	)		const

finaloverridevirtual

draw the contents at the designated position

Parameters

painter	QPainter to use
x	x-position, where the drawing starts [Pixel]
y	Y-position of the baseline, where the drawing starts [Pixel]
currentEv	JKQTMathTextEnvironment object describing the current drawing environment/settings

Returns: the x position which to use for the next part of the text

Implements JKQTMathTextNode.

Parameters

painter	painter to use for determining the size
currentEv	current environment object

Returns: all important box size parameters packed as JKQTMathTextNodeSize

Implements JKQTMathTextNode.
