QFileDialog->getOpenFileName() errors in debugger.

I imagine so, it's just an oddity. The point was you understand that whatever you do to the object has no bearing on the QFileDialog::getOpenFileName.

My first advice would've been to try the Qt dialog, but apparently that's not the problem. Second thing that comes to mind is to try the regular way of opening the dialog, i.e. using show on an initialized object. Third thing you could try is to disable the side pane of the dialog (I'm too lazy to check the docs for the correct flag, but I'm sure you can manage that).

Just to know.
Which compiler are you using ?

mzimmers

@mrjj MinGW5.3.0 32bit for C++

mrjj

@mzimmers
ok, just the one that comes with Qt ?
Could you try a clean default GUI project and just a pushbutton with
QString fileName = QFileDialog::getOpenFileName(this, tr("Open File"),
"/home",
tr("Images (*.png *.xpm *.jpg)"));
to see if it always says it or it somehow is related to your code ?

How did you install Qt?

Look also at QTBUG-67711 and QTBUG-63789. Probably what you're hitting.

mzimmers

@kshegunov: very interesting. I probably installed Qt via the maintenance tool, though I'm not 100% sure. I don't mind removing and re-installing, but would you suggest using the maintenance tool, or just downloading from the web site?

kshegunov

Actually I would've suggested trying building the library yourself. I'm not sure if you're going to get enough bang for the buck though, even if it helps at all; building Qt on windows is somewhat finicky ...

mzimmers

Yeah, I think I'll just live with it until it gets shaken out. My primary concern was that I was doing something wrong; if it's a library mismatch, I can ignore the symptoms, especially since they don't occur outside of the debugger.

Thanks, all.

What did you mean by this? I'm ready to try something new.

QFileDialog * dialog = new QFileDialog(this);
dialog->setNameFilters(...);
// ... more ...
dialog->show();
