Member Function Documentation

draw()

void QwtPlainTextEngine::draw ( QPainter * painter, const QRectF & rect, int flags, const QString & text ) const

overridevirtual

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 230 of file qwt_text_engine.cpp.

heightForWidth()

double QwtPlainTextEngine::heightForWidth ( const QFont & font, int flags, const QString & text, double width ) const

overridevirtual

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 172 of file qwt_text_engine.cpp.

mightRender()

bool QwtPlainTextEngine::mightRender ( const QString & ) const

overridevirtual

Always true. All texts can be rendered by QwtPlainTextEngine

Implements QwtTextEngine.

Definition at line 240 of file qwt_text_engine.cpp.

textMargins()

void QwtPlainTextEngine::textMargins ( const QFont & font, const QString & , double & left, double & right, double & top, double & bottom ) const

overridevirtual

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 210 of file qwt_text_engine.cpp.

textSize()

QSizeF QwtPlainTextEngine::textSize ( const QFont & font, int flags, const QString & text ) const

overridevirtual

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

Calculated size

Implements QwtTextEngine.
