void QwtPlainTextEngine::draw (  QPainter *  painter, const QRect &  rect, int  flags, const QString &  text )  const [virtual]

Draw the text in a clipping rectangle. A wrapper for QPainter::drawText. Parameters: painter  Painter rect  Clipping rectangle flags  Bitwise OR of the flags used like in QPainter::drawText text  Text to be rendered Implements QwtTextEngine. Definition at line 213 of file qwt_text_engine.cpp. References QwtPainter::drawText().

int QwtPlainTextEngine::heightForWidth (  const QFont &  font, int  flags, const QString &  text, int  width )  const [virtual]

Find the height for a given width Parameters: font  Font of the text flags  Bitwise OR of the flags used like in QPainter::drawText text  Text to be rendered width  Width Returns: Calculated height Implements QwtTextEngine. Definition at line 155 of file qwt_text_engine.cpp.

bool QwtPlainTextEngine::mightRender (  const QString &   )  const [virtual]

Test if a string can be rendered by this text engine. Returns: Always true. All texts can be rendered by QwtPlainTextEngine Implements QwtTextEngine. Definition at line 223 of file qwt_text_engine.cpp.

void QwtPlainTextEngine::textMargins (  const QFont &  font, const QString &  , int &  left, int &  right, int &  top, int &  bottom )  const [virtual]

Return margins around the texts Parameters: font  Font of the text left  Return 0 right  Return 0 top  Return value for the top margin bottom  Return value for the bottom margin Implements QwtTextEngine. Definition at line 193 of file qwt_text_engine.cpp.

QSize QwtPlainTextEngine::textSize (  const QFont &  font, int  flags, const QString &  text )  const [virtual]

Returns the size, that is needed to render text Parameters: font  Font of the text flags  Bitwise OR of the flags used like in QPainter::drawText text  Text to be rendered Returns: Caluclated size Implements QwtTextEngine. Definition at line 174 of file qwt_text_engine.cpp.
