QFileDialog to default to AppData?

Question

In my program, I have a button that opens a getOpenFileName dialog like this:

path = QFileDialog::getOpenFileName(this, tr("Select region"), "%APPDATA%", tr("region file"));

I want the dialog to default to the users AppData folder. All users are running Windows (XP or higher). How could I ensure it defaults to AppData?

You can use QDesktopServices static method (Qt4):

QString path = QDesktopServices::storageLocation(QDesktopServices::DataLocation);

In Qt5:

QString path = QStandardPaths::standardLocations(QStandardPaths::DataLocation).at(0);

To get Roaming folder:

QSettings settings(QSettings::IniFormat, QSettings::UserScope, "AppName", "application");
QString location = QFileInfo(settings.fileName()).absolutePath() + "/";

In my case path was:

C:/Users/maxim.makhun/AppData/Roaming/AppName/

I get an error: storageLocation is not a member of qdesktopservices... and so is datalocation. – mrg95 Jan 13 '14 at 10:06
Yes. 5.0.2 and I've included QDesktopServices. I'm looking at the documentation now, and I'm doing exactly that??? hmmm – mrg95 Jan 13 '14 at 10:09
I improved my answer. There're some changes in Qt5. – Maxim Makhun Jan 13 '14 at 10:11
It defaulted to Appdata/Local. Can I change that to Roaming? or just Appdata? – mrg95 Jan 13 '14 at 10:15
Ah. In this case I used QSettings. There were issues with QStandardPaths – Maxim Makhun Jan 13 '14 at 10:28
