QFileDialog::getOpenFileName() gets stucked

[elcuco]

Ok, this is wierd, but some application which works PERFECTLY on Linux, does not run on win32. The linux system is OpenSUSE 10 qt-rsync, and on Windows it's mingw4 on XP Qt 4.1.0 (from the released binaries).

The code which gets stucked is:

QString s = "Images (*.png *.jpg *.jpeg *.bmp *.gif *.pnm *.xpm)";
	QString s1 = QFileDialog::getOpenFileName(
                    NULL,
                    "Choose a scanned (300dpi) image",
                    "",
                    s );
 
	if (s1.isEmpty())
		return;

QString s = "Images (*.png *.jpg *.jpeg *.bmp *.gif *.pnm *.xpm)";
	QString s1 = QFileDialog::getOpenFileName(
                    NULL,
                    "Choose a scanned (300dpi) image",
                    "",
                    s );
    
	if (s1.isEmpty())
		return;

When I choose a file in the getOpenFileName, the application gets stucked. If I cancel, it works. The same code on a save functions works. Copying the code from the save routine gets the same effect (applicatino gets stucked).

Any ideas how to debug such thing?

Maybe it's this problem?

could be, but i get the same problem even when i search for "*". i will upgrade to qt4.1.1 (or 2?) and retest.

Jusi to bump this up, still no go. The code works perfectly on Linux but gets killed on Win32.

Eventuall I have this code, which seems to work:

QString s = QFileDialog::getOpenFileName(
                    NULL,
                    tr("Choose a scanned (300dpi) image"),
                    QDir::home().path(), 
                    tr("Images (*.png *.jpg *.jpeg *.bmp *.gif *.pnm *.xpm)"),
                    NULL,
                    QFileDialog::DontUseNativeDialog
    );

QString s = QFileDialog::getOpenFileName(
                    NULL,
                    tr("Choose a scanned (300dpi) image"),
                    QDir::home().path(), 
                    tr("Images (*.png *.jpg *.jpeg *.bmp *.gif *.pnm *.xpm)"),
                    NULL,
                    QFileDialog::DontUseNativeDialog
    );

Not optimal, but what the hell... I think I will report this to the trolls, as it seems a bug in win32's version of Qt 4.1.1

Just to mention, the code in the first post works fine on my WinXP+SP2 with Qt 4.1.1..

[elcuco]

also for me in other projects... this why it's so wierd.

I will post a link to the full code when I release it, maybe more eyes will be able to see the problem (the applicaiton is an GUI for a hebrew OCR library, google for hocr if you want more info).
