[Solved] Any Chance to get result of QFileDialog::getOpenFileName
-
Hi again,
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);
if(!p_State)return;
@
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.
kind regards,

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.
