Passing unique_ptr for Qt methods

[Exotic_Devel]

I'm making use of unique_ptr in the code, but when I try to pass this pointer to a method Qt, the complilator complains about the conversion and does not recognize the method called passing a unique_ptr.

@
unique_ptr<QUiLoader> loader ( new QUiLoader());
unique_ptr<QFile> ui_file (new QFile("Forms/MainWindow.ui"));
ui_file->open(QFile::ReadOnly);
return loader->load(ui_file, parent);@

output error
_
error: no matching function for call to ‘QUiLoader::load(std::unique_ptr<QFile>&, QWidget*&)’
return loader->load(ui_file, parent);
note: no known conversion for argument 1 from ‘std::unique_ptr<QFile>’ to ‘QIODevice*’_

For this I need to use the function get () of unique_ptr

@
unique_ptr<QUiLoader> loader ( new QUiLoader());
unique_ptr<QFile> ui_file (new QFile("Forms/MainWindow.ui"));
ui_file->open(QFile::ReadOnly);
return loader.get()->load(ui_file.get(), parent);

Just a couple of notes.
unique_ptr has overloaded operator-> so instead of
@
loader.get()->load(...
@
you can just write
@
loader->load(...
@
Another thing is that there's no real benefit in dynamically allocating these objects and using unique_ptr here. Actually it's worse because you need to create unique_ptr instance and reference objects indirectly.
This essentially does the same, just faster and easier to read:
@
QUiLoader loader;
QFile ui_file("Forms/MainWindow.ui");
ui_file.open(QFile::ReadOnly);
return loader.load(&ui_file, parent);
