[freddy311082]

Hi guys...

I need to open a file with it default program defined in the OS.

I'm doing this to open a pdf:
@qDebug() << QDesktopServices::openUrl(QUrl("file:///home/freddy/unordered.pdf", QUrl::TolerantMode));@
and my program crash it . I test with this code too:
@qDebug() << QDesktopServices::openUrl(QUrl("/home/freddy/unordered.pdf", QUrl::TolerantMode));@
and
@qDebug() << QDesktopServices::openUrl(QUrl("file:///home/freddy/unordered.pdf"));@
and the result is the same:
@The program has unexpectedly finished.@
I'm using Qt5.2.1 in Archlinux, but my app will run over Mac and Windows too,

any advice please ?? thanks !!!

best regards

Hi,

Can you try building your url using "fromLocalFile":http://qt-project.org/doc/qt-5/qurl.html#fromLocalFile ?

Works for me on OSX (Qt-5.3-beta) and Ubuntu (Qt-5.2.1)
@
qDebug() << QDesktopServices::openUrl(QUrl::fromLocalFile("/home/user/tdd.pdf"));
qDebug() << QDesktopServices::openUrl(QUrl("file:///home/user/GUIdesign.pdf", QUrl::TolerantMode));
@

Do you have a core file? Could you post a backtrace log here.

You don't need to add "file://" if you use @QUrl::fromLocalFile(...)@

[freddy311082]

yes...

my core file is only:

@
#include <QDesktopServices>

int main()
{
qDebug() << QDesktopServices::openUrl(QUrl::fromLocalFile("file:///home/user/unordered.pdf"));
return 0;
}
@

and the backtrace log just tell me

@Starting /home/freddy/Trabajo/bpg/andy&pedro/proyecto/build-adviser-Clang-Debug/adviser...
QML debugging is enabled. Only use this in a safe environment.
The program has unexpectedly finished.

You need to initialize QApplication in order in use QDesktopServices

Try this
@
#include <QApplication>
#include <QDebug>
#include <QUrl>
#include <QDesktopServices>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

qDebug() << QDesktopServices::openUrl(QUrl::fromLocalFile&#40;"/home/user/tdd.pdf"&#41;);
qDebug() << QDesktopServices::openUrl(QUrl("file:///home/user/GUIdesign.pdf", QUrl::TolerantMode));

return 0;

}
