Searching for strings within a QTextBrowser?

odonnemr

Are there any built in functions for this? My end goal is to highlight words within the open page of a help document (which is a QTextBrowser) that the user searches for. I know about the QString find() function, but I'm wondering if there's something similar for QTextBrowser. Thanks in advance

QTextBrowser inherits "QTextEdit::find()":http://doc.trolltech.com/4.7/qtextedit.html#find

Is there a way to highlight every occurrence of the word in the text browser, or maybe a way to scroll through them?

Iterating through find() until it returns false will return each instance of the pattern. Then you can highlight or do whatever you need to.

Wouldn't it just return "true", not the word or location of the word? Is there a way I could make a note of the location in the browser when it returns true?

mlong

Per the docs, when it finds a match, it sets the cursor to select the location. You could make a copy of the cursor location with QTextEdit::textCursor() every time a location is found.

Disclaimer, it's been a while since I had to use any of this code, so your mileage may vary.

Hi,
This [http://doc.qt.nokia.com/4.7-snapshot/uitools-textfinder.html] example might help you. I was doing the same stuff sometime back.

Hi,
also you can use regular expression method :

bq. Detailed Description

This element provides a validator, which counts as valid any string which matches a specified regular expression.
