\class Q3Button
\brief The Q3Button class is a compatibility base class of button
widgets
\compat
\bold{In new code, use QAbstractButton.}
To subclass Q3Button, you must reimplement at least drawButton()
(to draw the button's outline) and drawButtonLabel() (to draw its
text or pixmap). It is generally advisable to reimplement
sizeHint() as well, and sometimes hitButton() (to determine
whether a button press is within the button).
*/
/*!
Constructs a standard button called \a name with parent \a parent,
using the widget flags \a f.
*/
Q3Button::Q3Button( QWidget *parent, const char *name, Qt::WindowFlags f )
: QAbstractButton( parent, name, f )
{
}
/*!
Destroys the button.

Q3Button::~Q3Button()
{

/*!
\fn void Q3Button::paintEvent( QPaintEvent *event)
Handles paint events, received in \a event, for buttons. Small and
typically complex buttons are painted double-buffered to reduce
flicker. The actually drawing is done in the virtual functions
drawButton() and drawButtonLabel().
\sa drawButton(), drawButtonLabel()

\fn void Q3Button::drawButton( QPainter *painter)
Draws the button on the given \a painter. The default
implementation does nothing.
This virtual function is reimplemented by subclasses to draw real
buttons. At some point, these reimplementations should call
drawButtonLabel().
\sa drawButtonLabel(), paintEvent()

Draws the button text or pixmap on the given \a painter.

buttons. It is invoked by drawButton().
