[Solved] Any Chance to get result of QFileDialog::getOpenFileName
In my GUI, I ask the user for Text and Filepaths. I perform der Text input by
QString p_Result = QInputDialog::getText(this, tr("Enter Something"),tr("Something"),QLineEdit::Normal,QString::fromUtf8(tmp.c_str()),&p_State);
In the second line, i skip further computation is the user "aborted" his input rather than pressing ok.
So far, so god.
But if I ask the user to input a Filepath:
static QString getOpenFileName(QWidget *parent = 0,
const QString &caption = QString(),
const QString &dir = QString(),
const QString &filter = QString(),
QString *selectedFilter = 0,
Options options = 0);
there is no such output parameter bool *ok like in
static QString getText(QWidget *parent, const QString &title, const QString &label,
QLineEdit::EchoMode echo = QLineEdit::Normal,
const QString &text = QString(), bool *ok = 0, Qt::WindowFlags flags = 0);
How do I check, wheather the user pressed ok oder abort? Checking the QString against QString("") only seems to be a workaround.

Why do you think this is a "workaround"?! The dialog only has 2 results: Either the user selected a path or he didn't. Which is indicated by an empty string.

The getOpenFileName documentation states that if the user canceled, the string returned is null. So the proper way to check is using QString::isNull();
Thank you very much.
I was just wondering, if there is a more common usage.
