@Jeroentjehome Thank you, I'll try it

You're welcome !

Happy coding !

If I'm not completely mistaken Qt 4.8 does not assume c-strings to be in UTF-8 by default,
but instead assumes they are in the systems default encoding. Have you tried with:
QString::fromUtf8("mystring");?

Do you have Qt configured to use that display ?

Good to know that you have found your problem and solved it.

Please mark thread as solved. This makes it easier for others.

AFAIK, there's no pre-built widget for that. You should take a look at e.g. KDE's screen savers implementation to see how they do it.

@jjan
Just for an iteration the code reads line by line. As long as the search text is found, it will provide the remainder of the line. There is real dependency to the content as long as it is displayble (probably also some non-displayable characters). There are some special characters marking the end of lines (line feed (LF) and carriage return (CR) are those at least).

你解决了吗 可以联系我吗qq86252715，我现在也在搞这个

My comment might not be a reason it does not work for you, but every QObject derived class require Q_OBJECT macro at least if you have any signal/slot defined in it.
I never tried to write template with such macro and believe it is not supported and will be not handled properly by mocing.
It might be possible manually create required code instead, but I doubt this solution will be portable.

In other words my impression is templates are no-no with QObject derived classes.

@Adrianos

the Cellchanged signal is emitted after the content change so you can't prevent modefication of a cell by this signal

@SGaist Hi thank you,
