Transparent widgets

This won't work.

How does "this won't work"?

What am I doing wrong ?

Well... I didn't say that it will, but you should start from the simplest solutions

It shows my pushbutton + pushbutton text value + button shaPe.
It shows nothing of the background.

I agree we should try simplest things first.

Either this is a wrong approach or it's the QPalette bug. Try to subclass QAbstractButton and draw only text in paintEvent.

Actually I would like to see nothing from my button, not even the text : 100% transparent.
But subclassing as you propose and using paintEvent is beyond my knowledge. But thank you for helping out. I hope I can find some information about this subclassing in the QT3 book.

You should rather look for a book about programming in C++.

class Button : public QAbstractButton
{
   public:
      Button( QWidget *parent = 0 ) : QAbstractButton( parent ) {}
   protected:
      void paintEvent( QPaintEvent * ) {}
};

class Button : public QAbstractButton
{
   public:
      Button( QWidget *parent = 0 ) : QAbstractButton( parent ) {}
   protected:
      void paintEvent( QPaintEvent * ) {}
};

I am more impressed by your skills than by my lack of knowledge (which is huge!!).
Of course the piece of code you gave me works 100%.

Thank you very much.
