Curious Problem QFileDialog getexistingdirectory

[ndahiya]

Hi all,
I am facing a peculiar problem with QFileDialog::getexistingdirectory. I am using QT with OpenCv. I need to process all the images(.tif) in a folder and save the processed images in a different folder. I get the files list like : QStringList files = path.entryList(filters);
path of first file " QString firstfile = files.first()"
but once i add the code to load the file as IplImage "IplImage *input = cvLoadImage((const char*)firstfile.toAscii()) it compiles fine but when I run it, the get input directory dialog box goes blank!! I tried everything including writing the paths of all files in a text file and then using that to load images. But I end up with the same problem...
SOS!!

Hi,
I wrote a simple version of the program just to illustrate the problem I'm facing. I am attaching the code. In the following function void Widget:rocessfiles() try with this line commented and uncommented. // IplImage *input = cvLoadImage((const char*)firstfile.toAscii());

Thanks,
