'operator=' is deprecated: Use QDir::setPath() instead

Question

Simple program that opens a GUI, you click one button to set curDir, click another button to set savDir, and a third button does some C++ code similar to

ls -l curDir > savDir.txt

One of my Qt functions:

void dirList::on_savBut_clicked(){
    savDir = QFileDialog::getExistingDirectory(
                this,"Save Location",QDir::homePath());
    savPath = savDir.absolutePath();
    ui->savText->setText(savPath);
}

On the savDir = QFileDialog::getExistingDirectory(... line I get a warning:

'operator=' is depreciated: Use QDir::setPath() instead

Could anyone give an example how I might incorporate setPath()?

Answer 1

You can simply write

savPath = QFileDialog::getExistingDirectory(
            this,"Save Location",QDir::homePath());

Without using savDir.

Answer 2

I believe setPath is just a drop in replacement instead of using assignment for when updating a QDir with a QString path.

savDir = QFileDialog::getExistingDirectory(
                this,"Save Location",QDir::homePath());

simply becomes

savDir.setPath(QFileDialog::getExistingDirectory(
                this,"Save Location",QDir::homePath()));
