结构体成员变量说明

AutoText = 0

The text format is determined using QwtTextEngine::mightRender() for all available text engines in increasing order > PlainText. If none of the text engines can render the text is rendered like QwtText::PlainText.

◆ MathMLText

MathMLText

Use a MathML (http://en.wikipedia.org/wiki/MathML) render engine to display the text. In earlier versions of Qwt such an engine was included - since Qwt 6.2 it can be found here: https://github.com/uwerat/qwt-mml-dev

To enable MathML support the following code needs to be added to the application:

QwtText::setTextEngine( QwtText::MathMLText, new QwtMathMLTextEngine() );
