How to save file with QFileDialog

[chochatown]

Hello
i try to use Qfiledialog for a save dialog too
but ther is an error that i cant see the reason that's my code

<code>
void Frm::evtBtnFileTarget()
{
QFileDialog::getSaveFileName(this, "Save file", "", ".conf");
}
</code>

that's the error:

Frm.cpp:945: erreur: no matching function for call to «QFileDialog::getSaveFileName(Frm* const, const char [10], const char [1], const char [6])»
/usr/include/qt4/QtGui/qfiledialog.h:201: note: candidats sont: static QString QFileDialog::getSaveFileName(QWidget*, const QString&, const QString&, const QString&, QString*, QFlags<QFileDialog::Option>)



thx

your class Frm must be a subclass of QWidget or pass 0 instead of this as the first parameter

QString s = QFileDialog::getSaveFileName(
"/home",
"Images (*.png *.xpm *.jpg)",
this,
"save file dialog",
"Choose a filename to save under" );

use this works fine

Thanks for the timely response. I'm sure these guys have been struggling to find this answer since 2009.

Been a few of these lately. I suspect there will be another spate in three years
