QSortFilterPoxyModel not filtering

[ayanda83]

Tried with one of the other filter methods?


But you set it to DecorationRole, which is not a string.

I set it to both DecorationRole and DisplayRole so that I can display both the file icon and the file name. I also tried to display the file name only by setting it to DisplayRole only and that didn't work either.

If you look at my slot below, is it suppose to do what I want it to do? Because I am not too sure.

void MainWindow::on_btnSearch_clicked()
{
    QString patternStr = ui->leSearch->text();
    proxyModel->setFilterFixedString(patternStr);
}

void MainWindow::on_btnSearch_clicked()
{
    QString patternStr = ui->leSearch->text();
    proxyModel->setFilterFixedString(patternStr);
}

To copy to clipboard, switch view to plain text mode

No.
First, the filter role has obviously nothing to do with display.
Second, the filter role is only a single role.
Third, a binary OR between two non-flag values is seldomly a valid value.
Fourth, in you case you where lucky as one of the value is 0 so the result of the OR is the second value.

So no, you did not set both DecorationRole and DisplayRole, as this is impossible and by sheer luck you only set DecorationRole.

I also tried to display the file name only by setting it to DisplayRole only and that didn't work either.

And you also tried with FileNameRole?

    proxyModel->setFilterFixedString(patternStr);

Yes, that looks reasonable.

I set the display role to Qt:isplay only and the program does filter certain strings. For example the string "TW-" is filtered perfectly fine but other strings don't filter or they crash the program. I am pretty sure the problem is with line 29 in my constructor but I am not really sure what I need to do there.
