Mac right-to-left issue

[gtabares]

All,

I'm seeing some different behavior on Mac OSX (when compared to Windows) with regards to right-to-left layout direction. It's hard to believe the following is broken:

@
#include <QtGui/QComboBox>
#include <QtGui/QApplication>
#include <QtGui/QVBoxLayout>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
a.setLayoutDirection(Qt::RightToLeft);

QWidget w;
QVBoxLayout *layout = new QVBoxLayout();
QComboBox *comboBox = new QComboBox(&w);
        
layout->addWidget(comboBox);
        
w.setLayout(layout);
w.setMinimumWidth(300);
w.show();

comboBox->insertItems(0, QStringList()
                  << "This is a test"
                << "This is a second test");

return a.exec&#40;&#41;;

}
@

On Windows, the layout is right-to-left as expected. On Mac, the layout is still left-to-right. I'm using Qt 4.7.2 (Cocoa) on OSX Lion (10.7.2). I'm compiling with XCode 4.2.1. Is anyone seeing anything similar?

Does it change anything forcing the layout direction even on the vertical layout too? Could be a problem of layout parenting? Just thinking...

Is this the cause of your problem?

bq. From "QWidget docs/layoutDirection":http://doc.qt.nokia.com/4.7/qwidget.html#layoutDirection-prop:
This method no longer affects text layout direction since Qt 4.7.

It doesn't change anything...

I think that's for widgets. However in my code I'm setting it for the entire application. Not sure if there is a difference.

The application setting is just the default for the widgets.
