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

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.
/home/freddy/Trabajo/bpg/andy&pedro/proyecto/build-adviser-Clang-Debug/adviser crashed@

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;

}

@ QString str(QDir::currentPath());
str.append("/ManualUsuario.pdf");
QDesktopServices::openUrl(QUrl::fromLocalFile(str));@
