@Pada_ Hi,

You are using your RegExp in Wildcard mode.
try

QRegExp regExp(filterC, Qt::CaseInsensitive, QRegExp::RegExp);
//or
QRegExp regExp(filterC, Qt::CaseInsensitive, QRegExp::RegExp2); //greedy quantifier

@Pada_ To add to @Gojir4 : you should use QRegularExpression, QRegExp is deprecated.

@jsulm

QRegularExpression is not setting sortModel..

[jsulm]

@Pada_ said in Qt QRegExp not work ..:

QRegularExpression is not setting sortModel..

What do you mean?

[Pada_]

@jsulm

QRegularExpression regExp ("text");

sortModel-> setFilterRegExp (regexp);

Can not be set in the model.

Hi,

What exactly are you try to filter on your model ?
You should give examples of what you have and what you expect.

@SGaist

Hello..

An attribute is a name and a value.

If you write the value of the attribute name = attribute

I want to show it in sortModel.

Even if you do not use the name of an attribute,

or

Even if you do not use the value of the attribute,

I want to show something similar (containing).

What is "attribute" for you ?

Again, please provide concrete examples.
