If you want to create a captcha, just create a custom widget (custom painting) or a pixmap.
To enter the code, use a line edit.

i think he wants to grab an existing captcha from a website, not creating one by himself. If understand him correctly, he wants to build a wrapper for web-logins.

is the webpage is in a qwebview or you are using qnetworkacess to make http requests is quite easy...
just parse the html and get that part...
frame=page.mainFrame();
and then QWebElement to parse.
Download the image... and show to the user.


is you are trying to get the captcha from an external browser (ie, etc)... that's much more more more complicated.
