frameless window can't minimize or maximize on mac using Qt 5.4

Hi

I am using Qt 5.4 on MacOSX. We have created Frameless Windows and have Minimize and maximise button. But showMinimized() and showMaximized() not working in case of Qt 5.4. But in previous Qt version it is working.

Note: I have attached sample application TestMinimized. My application is fully developed in Qt 5.4 not using any Cocoa program. Kindly tell me me the solution.

Thanks
