Opening an URL that contains accents

[Nyphel]

Hi,

I've wrote a small application that search for movies in my computer, list them, order the list and display the list to the user (using a a QTreeWidget). When the user double clic a movie name, my application use the QDesktopServices in order to launch the movie.

Here is the sample code used to launch the movie :

QString path_to_a_movie = "N:/The movies/666 - La malédiction";
 
     QUrl my_url;
     my_url = QUrl::fromLocalFile(path_to_a_movie);
 
     QDesktopServices::openUrl(my_url);

QString path_to_a_movie = "N:/The movies/666 - La malédiction";

     QUrl my_url;
     my_url = QUrl::fromLocalFile(path_to_a_movie);

     QDesktopServices::openUrl(my_url);

To copy to clipboard, switch view to plain text mode 

If the [path_to_a_movie] contains accents, like in the example, the movie isn't launched.
I don't understand how to resolve this problem... Has someone an idea ?

If you construct QStrings this way, you have to set a codec using QTextCodec::codecForCStrings() to let Qt know which codec to use for string literals.

In reality, here is the slot that handle double clics on a movie name in the QtreeWidget :

void interface_impl::SLOT_launch_movie(QTreeWidgetItem *item, int column)
{
     QUrl my_url;
     my_url = QUrl::fromLocalFile(item->text(1));
 
     QDesktopServices::openUrl(my_url);
}

void interface_impl::SLOT_launch_movie(QTreeWidgetItem *item, int column)
{
     QUrl my_url;
     my_url = QUrl::fromLocalFile(item->text(1));
     
     QDesktopServices::openUrl(my_url);
}

To copy to clipboard, switch view to plain text mode 

So the QString is directly returned by a QTreeWidgetItem, and I suppose - but I don't know - that there is no char* / QByteArray convertion

Are those strings displayed properly in the QTreeWidget?

[Nyphel]

Yes, they are

Perhaps the openURL function has not been written to accept accents... Like generally there is no accentuation in web URLs.

Which Qt version do you use?

[Nyphel]

Qt 4.2.3, I will probably use the Qt 4.3 next week.

It seems that this problem was fixed in Qt 4.3.0: http://trolltech.com/developer/task-...ntry&id=141352

Oh yes, thank you for this tip !
