Define a QRegExp

[aaditya190]

Like i have tried some examples.. to include characters A-Z, i used QRegExp rx("\\b{A-Z}");.. this works.. What i want to know is what shall i do to include curly braces {} also as a part of the expression? Whatever we write in {} is included in the expression.. What to write to include {} as a part of the expression??

Sorry my previous post was wrong - curly brackets are special characters used when you want to define a number of occurences of an expression, so in order to match them, you have to use backslash:

QRegExp rx("\\{(\\w|\\s)+\\}");
qDebug() << rx.indexIn("{this one}") << rx.indexIn("not this one");

QRegExp rx("\\{(\\w|\\s)+\\}");
qDebug() << rx.indexIn("{this one}") << rx.indexIn("not this one");

Sorry I totally forgot about this.

Thanks for the reply.. But this piece of code is also not working..
Instead i tried this .. QRegExp rx("\\{()+\\}");.. This worked.. When it encounters simultaneous {}, it works. What i want to do is to make individual curly braces i.e { and } work independently. Can you help me with this?

This regular expression works without problems - it all depends on what you want to capture.

Use \\{ to match {, and \\} to match }. What else do you need ?
