How to customize my window default style ?

[youzking]

hello ,
i want to change the default theme that Qt use (depending on the OS) ,
for example i want to replace the (close , minimize, maximize) buttons , ( window flags doesn't do what i want ) ,
i want to use the blur style for my application ( in win7) , in other words , i want a part of my application look like the top window style ( in windows7 );
because when using a QMainWindow the default style is too classic for a creative application !! (a simple window , a simple menubar, tabs .... )
i want to customize all of this ,

thanks for helping

Windows flags, stylesheet and style are the only option for you. You can look at the Qt Assistant for three topics.
