Custom widget table sort

[giantdragon]

I have QTableWidget with custom progress bars (derived from QWidget), inserted into table with setCellWidget. Each bar have "progress" property and I need to sort by it. I reimplemented "<" operator, but sorting doesn't work and operator "<" not even called.

Header:

bool operator < (const ProgressBar &other);

bool operator < (const ProgressBar &other);

To copy to clipboard, switch view to plain text mode 

CPP:

bool ProgressBar::operator < (const ProgressBar &other)
{
    return progress < other.progress;
}

bool ProgressBar::operator < (const ProgressBar &other)
{
    return progress < other.progress;
}
