Qt Stylesheets: How to apply style to menus? How to remove blue tinge around QTextEdit?

I am trying to make the menubar a gradient black colour and that works fine, except for the menu headings.

Here's the stylesheet i'm using:

 QString styleSheet = "QMenuBar{background: qlineargradient(x1:0,x2:0,y1:0,y2:1,stop:0 #cccccc, stop:0.4 gray)} QStatusBar{background: qlineargradient(x1:0,x2:0,y1:0,y2:1,stop:0 #cccccc, stop:0.4 gray);color:white;} ";

this->setStyleSheet(styleSheet);

1. How do I apply the style to the meny headings too?
2. There is a blue tinge all around the QTextEdit which I can't get rid of. Is there a way to set it to black?

Thanks :)

1. for aply color to the headings:

   QMenuBar::item{
       background-color: qlineargradient(x1:0,x2:0,y1:0,y2:1,stop:0 #cccccc, stop:0.4 gray)
   }
   

2. For the blue tinge all around the QTextEdit:

   QTextEdit{
       border: 0
   `
