I don't know how mac associates file extensions with programs but it is different than windows. How did you "associate" the file with the app on the mac?

Honestly, this may require you understanding how the mac runs programs when associations are created. The only reason that your executable gets the file name on a windows machine is because of the windows registry. When you associate a file with a program on a windows machine, information is put into the registry that allows windows to execute your program using the shell command line. In other words it literally mimics sending arguments to your program as if it were typed out in a command line.

If the mac system has a different way of sending associated file information to its programs, this method will not work. Since I am not a mac user...I really don't know how it works on a mac.

thak you for your reply
in MAC when you right click to file.xyz and "obtain info" you can associated one app at this file exstension.
in this way when i double click on all files with this extension app starts.
but not passing file path

Hi,

What do you mean by "passing file path" ? Dropping a file on your application icon ?

OS X and Windows are different beasts. Have a look at "QFileOpenEvent":http://qt-project.org/doc/qt-5/QFileOpenEvent.html and the doc not that comes with it

Hi SGaist,

thak you for your reply,
i have reimplemented this method
bool App::event(QEvent *event){
if(event->type()==QEvent::FileOpen){
QFileOpenEvent *fev=static_cast<QFileOpenEvent *>(event);
loadFile(fev->file());
return true;
}
return QApplication::event(event);
}

in my application.

and now when i have the software started and i double click in associated file,the file is opened in my software.
but i f the program is close and i double click on file i have one error in report
QWidgets::X ....

thanks

SGaist
