[Solved] .mp3 with Qt

[andre]

If you want to open the MP3 in the default application, just use something like this:

@
QUrl mp3Url = QUrl::fromLocalFile(theMp3FileName); //assuming you want to play a local file
QDesktopServices::openUrl(mp3Url);
@

0k. it starts, so thank you, but there is a problem: relative url dows not start..

[andre]

Could you try if it works if you use a full path to the file, instead of a relative one?

[spode]

yes, from full path it start.
@ QUrl mp3Url = QUrl::fromLocalFile("../qml/fileTrenner2/compleanno.mp3");
QDesktopServices::openUrl(mp3Url);
@ with relative path it does not start...

[loladiro]

Make sure your relative path is relative to "QDir::current()":http://doc.qt.nokia.com/4.7/qdir.html#current is. If it isn't you can always use
@QDir(QCoreApplication::applicationDirPath ()).absoulteFilePath("/path/")@

[spode]

thank you. @
QString s = QDir::current().absolutePath().append("/qml/fileTrenner2/compleanno.mp3");
QUrl mp3Url = QUrl::fromLocalFile(s);
QDesktopServices::openUrl(mp3Url); @
this snippet starts!

[loladiro]

If I were you I'd still use applicationDirPath, because the working directory usually changes throughout your application and you cannot be sure that it points to where you want it to point.

[spode]

i have this snippet:
@ QString s = QDir::current().absolutePath().append("/qml/fileTrenner2/compleanno.mp3");
QUrl mp3Url = QUrl::fromLocalFile(s);
QDesktopServices::openUrl(mp3Url); @
i want that the new window opens itself in minimized mode...or i want to move it.
how to do it?

[spode]

so, ideas for fixing?

[loladiro]

If you just want to play a mp3 file, I ask you to use $yourFavoriteSearchEngine. There are plenty of threads on the internet dealing with that.

[andre]

As loladiro suggested: use applicationDirPath.

[loladiro]

I think you can figure it out yourself. I am happy to give you tips, but I'm not going to write your app for you (or even parts of it).

[spode]

ahahah that is true! so, thanks!
