[Qt-interest] Qt Creator can not show application window

[黎 新懿]

hi friends,

I update my Qt to 4.5 on my Mac and I see something strange.

I press Command + R to run a simple application:

#include <QtGui/QApplication>
#include "mainwindow.h"
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QMainWindow w;
w.show();
return a.exec();
}


usually I am supposed to see the window show up after compiling, but  
now I can't

I can only see a

Starting ...

in the Application Output, but the window won't show up.

I check the project folder,  the Mac application is there, if I double  
click it then I can see the window showing

But in the new Qt Creator I just can't.

Did I miss anything?

Thanks in advance.
