Problems with QLineEdit

[RSX]

The first problem is that QLineEdit (or maybe QLocale) does auto spaces.

flags = 1048576;
QLocale convert;
ui->lineEditFlags->setText(convert.toString(flags));

flags = 1048576;
QLocale convert;
ui->lineEditFlags->setText(convert.toString(flags));

To copy to clipboard, switch view to plain text mode 

And the result I get is:

1 048 576

1 048 576

To copy to clipboard, switch view to plain text mode 

... with white spaces =/

The second problem is that:

QValidator *validator = new QIntValidator(this);
ui->lineEditFlags->setValidator(validator);

QValidator *validator = new QIntValidator(this);
ui->lineEditFlags->setValidator(validator);

To copy to clipboard, switch view to plain text mode 

It works fine until my program sets text to something like 1 048 576 (something that has whitespace). Then I can enter any character I want =/

Any way to fix these?
