Qt, QTextEdit, how to turn all the content in QTextEdit into a image. -

-

i want creat image contain qtextedit. , write following code create image.

qsize s = textedit->framesize(); qpixmap p(s); textedit->render(&p); p.save("textcontent.png", "png");

but can not contain invisible contents.(while contents long in qtextedit)

i wander if there way create image contain content in qtexteidt. , how.

thanks.

i think, can via qtextdocument * qtextedit::document () receive qtextdocument * of qtextedit, , draw qimage via void qtextdocument::drawcontents ( qpainter * p, const qrectf & rect = qrectf() )

it draws content of document painter p, clipped rect. if rect null rectangle (default) document painted unclipped.

check man here - http://harmattan-dev.nokia.com/docs/library/html/qt4/qtextdocument.html#drawcontents

or - other way - take text textedit via toplainhtml() or toplaintext() - what's more suitable needs , draw qimage via qpainter's method qpainter::drawtext()
