[Resolved] Pb using getSaveFileName and getOpenFileName dialog boxes

[Lucas S.]

Hi,

I get a weird problem using the QFileDialog static members. When I try to open a getSaveFileName dialog box, the box opens but the "Save" pushbutton doesn't work (clicking it doesn't do anything). And when I try to open a getOpenFileName dialog box, the box doesn't even show itself and return a empty QString. I don't know what's wrong with my program. I'm using Qt 4.8.6 with Windows 7 64bits, and developping on VS2008 (native compiler).

This is how I use the static members (OnSaveMotion and OnLoadMotion are public slots well connected to menu buttons) :

@void MotionControl::OnSaveMotion()
{
QString l_FileName = QFileDialog::getSaveFileName(this, tr("Save file"), "C:\untitled.md", tr("Exercise (.md)"));
QFile l_File = new QFile(l_FileName);
if(l_File->open(QIODevice::WriteOnly|QIODevice::Text))
{
// doing stuff
l_File->close();
}
else QMessageBox::critical(0, "Error", "Cannot save the file", QMessageBox::Close);
}@

@void MotionControl::OnLoadMotion()
{
QString l_FileName = QFileDialog::getOpenFileName(this, tr("Open Motion Data"), "C:\", tr("Motion Datas (.md)"));
QFile l_File = new QFile(l_FileName);
if(l_File->open(QIODevice::ReadOnly|QIODevice::Text))
{
// doing stuff
l_File->close();
}
else QMessageBox::critical(0, "Error", "Cannot open the file", QMessageBox::Close);
}@

Thanks for help,

Lucas
