QFileDialog + sorting -> problem
Message 1 in thread
Hello,
In my app I use QFileDialog to show all files in selected directory in
Detail viewmode with sorting enabled by Time:
#include <QtGui>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QFileDialog filedialog;
filedialog.setViewMode( QFileDialog::Detail );
QDir dir;
dir.setCurrent( "c:\\temp" );
dir.setFilter(QDir::Files | QDir::Hidden | QDir::NoSymLinks);
dir.setSorting(QDir::Size | QDir::Reversed
QDir::DirsFirst|QDir::LocaleAware);
filedialog.setDirectory ( dir );
return filedialog.exec();
}
filedialog opens c:\\temp directory but doesn't sort files list...I
checked qfiledialog.h and it appeared that setDirectory( QDir &dir) only
gets directory name from QDir...what about the rest? How can I sort
listview in filedialog according to what I need before it is shown to user?
Regards,
Marcin

QFileDialog::setDirectory() only sets the initial dialog path:
http://doc.trolltech.com/4.2/qfiledialog.html#setDirectory
This is maybe not very clear from the documentation, but the dialog does
not use any properties of the QDir argument apart from the path itself:
This is an overloaded member function, provided for convenience.

That's right!
But I also got response from support@.... they said that I should rather
use QObject::findChild() on QFileDialog to find QTreeView and then call
sortColumn(). I'm gonna check this right away.
