Hi,
I have a question about text selection in KHTML.  I am using KHTMLPart in my
small application. By default double clicking on a peace of text that
contains only one word selects the text. But I want to select a text that
contains multiple words by dragging a mouse with pressed left button, the
same way it works in Konqueror. I was able to get it to work by calculating
"number of characters" in a pixel in a DOM::Node by simply dividing DOM::
Node.nodeValue().length() / DOM::Node.getRect().width(); Then I just
calculated a DOM::Range in MouseMoveEvent and call
KHTMLPart::setSelection(DOM::Range). It works very well, but only when
DOM::Node does not span multiple lines. When it does the proportion
chars/pixel is wrong. I don't know x coordinate where the text ends.  I
tried to find how it is done in Konqueror, but could not find it. Can some
one point me how to do it or where to find similar code since it works in
Konqueror out of the box.
