Unable to have a QLabel sublass with transparent background

[yellowmat]

Hi,

I'm trying to developp a text widget with a transparent background. I subclass the QLabel class and reimplements its drawContents function in which I only draw the text as follow :

void CText::drawContents(QPainter* painter)
{
	painter->drawText(0, 0, this->text());
}

void CText::drawContents(QPainter* painter)
{
	painter->drawText(0, 0, this->text());
}

To copy to clipboard, switch view to plain text mode 

... but the gray background still appears.

The documentation says about this function :

Draws the label contents using the painter p. 
Reimplemented from QFrame.

Draws the label contents using the painter p. 
Reimplemented from QFrame.

To copy to clipboard, switch view to plain text mode 

so I thought maybe the paintEvent handler in a base class does something special as drawing the background, that's why I decided to reimplement the paintEvent handler with the following code :

void CText::paintEvent(QPaintEvent* event)
{
	QPainter* painter = new QPainter(this);
	painter->drawText(10, 10, this->text());
}

void CText::paintEvent(QPaintEvent* event)
{
	QPainter* painter = new QPainter(this);
	painter->drawText(10, 10, this->text());
}

To copy to clipboard, switch view to plain text mode 

... it still draws the background

Isn't it possible to just display the text without any background (i.e. with a transparent background) ?

Thanks in advance.
