# Bounding Text Being Rendered Using QPainter?

• I'm rendering some text using a QPainter, using the following call:

@painter->drawText(x, y, Bridge::to_qt(geometry.Data.Text.UTF8String));@

Prior to this, I'm setting the font for the QPainter. How would I find the bounding box of the text plotted at (x y) using a given QFont? Seems like there should be a way...

• Hi,

you can use "this":http://doc.qt.nokia.com/4.7/qpainter.html#drawText-13 drawText oberload to get the bounding rectangle.

Since that call doesn't break the text in lines, doesn't handle alignment, etc., you may use QFontMetrics to find out the bounding rectangle of your text.

• But his drawText also does not use line breaking :-)
But you are right, QFontMetrics is anothe sollution, perhaps the better one.

• Actually I was replying to OP, edited the post to make that clear.
