The TQRadioButton - and TQCheckBox classes provide only toggle buttons; TQPushButton and - TQToolButton provide both toggle and push buttons. - - Any button can have either a text or pixmap label. setText() sets - the button to be a text button and setPixmap() sets it to be a - pixmap button. The text/pixmap is manipulated as necessary to - create the "disabled" appearance when the button is disabled. - - TQButton provides most of the states used for buttons: - \list - \i isDown() indicates whether the button is \e pressed down. - \i isOn() indicates whether the button is \e on. - Only toggle buttons can be switched on and off (see below). - \i isEnabled() indicates whether the button can be pressed by the - user. - \i setAutoRepeat() sets whether the button will auto-repeat - if the user holds it down. - \i setToggleButton() sets whether the button is a toggle - button or not. - \endlist - - The difference between isDown() and isOn() is as follows: When the - user clicks a toggle button to toggle it on, the button is first - \e pressed and then released into the \e on state. When the user - clicks it again (to toggle it off), the button moves first to the - \e pressed state, then to the \e off state (isOn() and isDown() - are both FALSE). - - Default buttons (as used in many dialogs) are provided by - TQPushButton::setDefault() and TQPushButton::setAutoDefault(). - - TQButton provides five Q_SIGNALS: - \list 1 - \i pressed() is emitted when the button is pressed. E.g. with the mouse - or when animateClick() is called. - \i released() is emitted when the button is released. E.g. when the mouse - is released or the cursor is moved outside the widget. - \i clicked() is emitted when the button is first pressed and then - released when the accelerator key is typed, or when - animateClick() is called. - \i toggled(bool) is emitted when the state of a toggle button changes. - \i stateChanged(int) is emitted when the state of a tristate - toggle button changes. - \endlist - - If the button is a text button with an ampersand (\&) in its text, - TQButton creates an automatic accelerator key. This code creates a - push button labelled "Ro<u>c</u>k \& Roll" (where the c is - underlined). The button gets an automatic accelerator key, Alt+C: - - \code - TQPushButton *p = new TQPushButton( "Ro&ck && Roll", this ); - \endcode - - In this example, when the user presses Alt+C the button will call - animateClick(). - - You can also set a custom accelerator using the setAccel() - function. This is useful mostly for pixmap buttons because they - have no automatic accelerator. - - \code - p->setPixmap( TQPixmap("print.png") ); - p->setAccel( ALT+Key_F7 ); - \endcode - - All of the buttons provided by TQt (\l TQPushButton, \l TQToolButton, - \l TQCheckBox and \l TQRadioButton) can display both text and - pixmaps. - - To subclass TQButton, 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 - tqsizeHint() as well, and sometimes hitButton() (to determine - whether a button press is within the button). - - To reduce flickering, TQButton::paintEvent() sets up a pixmap that - the drawButton() function draws in. You should not reimplement - paintEvent() for a subclass of TQButton unless you want to take - over all drawing. - - \sa TQButtonGroup -*/ - - -/*! - \enum TQButton::ToggleType - - This enum type defines what a button can do in response to a - mouse/keyboard press: - - \value SingleShot pressing the button causes an action, then the - button returns to the unpressed state. - - \value Toggle pressing the button toggles it between an \c On and - an \c Off state. - - \value Tristate pressing the button cycles between the three - states \c On, \c Off and \c NoChange -*/ - -/*! - \enum TQButton::ToggleState - - This enum defines the state of a toggle button. - - \value Off the button is in the "off" state - \value NoChange the button is in the default/unchanged state - \value On the button is in the "on" state -*/ - -/*! - \property TQButton::accel - \brief the accelerator associated with the button - - This property is 0 if there is no accelerator set.
