#include <Q3Button>
This class is part of the Qt 3 support library. It is provided to keep old source code working. Мы настоятельно не рекомендуем использовать этот класс в новом коде. See Porting to Qt 4 for more information.
Inherits QAbstractButton.
The Q3Button class is a compatibility base class of button widgets
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 name with parent parent, using the widget flags f.
Уничтожает кнопку.
Draws the button on the given painter. Реализация по-умолчанию ничего не делает.
This virtual function is reimplemented by subclasses to draw real buttons. At some point, these reimplementations should call drawButtonLabel().
See also drawButtonLabel() and paintEvent().
Draws the button text or pixmap on the given painter.
This virtual function is reimplemented by subclasses to draw real buttons. It is invoked by drawButton().
See also drawButton() and paintEvent().
Handles paint events, received in 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().
Reimplemented from QWidget.
See also drawButton() and drawButtonLabel().
