A text engine for plain texts.
QwtPlainTextEngine renders texts using the basic Qt classes QPainter and QFontMetrics.
QwtPlainTextEngine::QwtPlainTextEngine | ( | ) |
Constructor.
QwtPlainTextEngine::~QwtPlainTextEngine | ( | ) | [virtual] |
Destructor.
void QwtPlainTextEngine::draw | ( | QPainter * | painter, | |
const QRectF & | rect, | |||
int | flags, | |||
const QString & | text | |||
) | const [virtual] |
Draw the text in a clipping rectangle.
A wrapper for QPainter::drawText.
painter | Painter | |
rect | Clipping rectangle | |
flags | Bitwise OR of the flags used like in QPainter::drawText | |
text | Text to be rendered |
Implements QwtTextEngine.
double QwtPlainTextEngine::heightForWidth | ( | const QFont & | font, | |
int | flags, | |||
const QString & | text, | |||
double | width | |||
) | const [virtual] |
Find the height for a given width
font | Font of the text | |
flags | Bitwise OR of the flags used like in QPainter::drawText | |
text | Text to be rendered | |
width | Width |
Implements QwtTextEngine.
bool QwtPlainTextEngine::mightRender | ( | const QString & | ) | const [virtual] |
Test if a string can be rendered by this text engine.

const QString & | , | |||
double & | left, | |||
double & | right, | |||
double & | top, | |||
double & | bottom | |||
) | const [virtual] |
Return margins around the texts
font | Font of the text | |
left | Return 0 | |
right | Return 0 | |

bottom | Return value for the bottom margin |
Implements QwtTextEngine.
QSizeF QwtPlainTextEngine::textSize | ( | const QFont & | font, | |
int | flags, | |||
const QString & | text | |||
) | const [virtual] |
Returns the size, that is needed to render text
font | Font of the text | |
flags | Bitwise OR of the flags used like in QPainter::drawText | |
text | Text to be rendered |
