.SH DESCRIPTION
The QRadioButton widget provides a radio button with a text or pixmap label.
.PP
QRadioButton and QCheckBox are both option buttons. That is, they can be switched on (checked) or off (unchecked). The classes differ in how the choices for the user are restricted. Check boxes define "many of many" choices, whereas radio buttons provide a" one of many" choice. In a group of radio buttons only one radio button at a time can be checked; if the user selects another button, the previously selected button is switched off.
.PP
The easiest way to implement a "one of many" choice is simply to put the radio buttons into QButtonGroup.
.PP
Whenever a button is switched on or off it emits the signal toggled(). Connect to this signal if you want to trigger an action each time the button changes state. Otherwise, use isChecked() to see if a particular button is selected.
.PP
Just like QPushButton, a radio button can display text or a pixmap. The text can be set in the constructor or with setText(); the pixmap is set with setPixmap().
Returns the accelerator associated with the button. See the "accel" property for details.
.SH "bool QButton::autoRepeat () const"
Returns TRUE if autoRepeat is enabled; otherwise returns FALSE. See the "autoRepeat" property for details.
.SH "void QButton::clicked ()\fC [signal]\fR"
This signal is emitted when the button is activated (i.e. first pressed down and then released when the mouse cursor is inside the button), when the accelerator key is typed or when animateClick() is called. This signal is \fInot\fR emitted if you call setDown().
.PP
The QButtonGroup::clicked() signal does the same job, if you want to connect several buttons to the same slot.
.PP
\fBWarning:\fR Don't launch a model dialog in response to this signal for a button that has autoRepeat turned on.

.SH "QButtonGroup * QButton::group () const"
Returns the group that this button belongs to.
.PP
If the button is not a member of any QButtonGroup, this function returns 0.
.PP
See also QButtonGroup.
.SH "bool QRadioButton::isChecked () const"
Returns TRUE if the radio button is checked; otherwise returns FALSE. See the "checked" property for details.
.SH "bool QButton::isDown () const"
Returns TRUE if the button is pressed; otherwise returns FALSE. See the "down" property for details.
.SH "bool QButton::isExclusiveToggle () const"
Returns TRUE if the button is an exclusive toggle; otherwise returns FALSE. See the "exclusiveToggle" property for details.
.SH "bool QButton::isOn () const"
Returns TRUE if the button is toggled; otherwise returns FALSE. See the "on" property for details.
.SH "bool QButton::isToggleButton () const"
Returns TRUE if the button is a toggle button; otherwise returns FALSE. See the "toggleButton" property for details.
Sets the text shown on the button. See the "text" property for details.
.SH "ToggleState QButton::state () const"
Returns the state of the toggle button. See the "toggleState" property for details.
.SH "void QButton::stateChanged ( int state )\fC [signal]\fR"
This signal is emitted whenever a toggle button changes state. \fIstate\fR is On if the button is on, NoChange if it is in the" no change" state or Off if the button is off.
.PP
This may be the result of a user action, toggle() slot activation, setState(), or because setOn() was called.
This property holds whether autoRepeat is enabled.
.PP
If autoRepeat is enabled then the clicked() signal is emitted at regular intervals if the button is down. This property has no effect on toggle buttons. autoRepeat is off by default.
.PP
Set this property's value with setAutoRepeat() and get this property's value with autoRepeat().
.SH "bool checked"
This property holds whether the radio button is checked.
.PP
This property will not effect any other radio buttons unless they have been placed in the same QButtonGroup. The default value is FALSE (unchecked).
.PP
Set this property's value with setChecked() and get this property's value with isChecked().
If the pixmap is monochrome (i.e. it is a TQBitmap or its depth is 1) and it does not have a mask, this property will set the pixmap to be its own mask. The purpose of this is to draw transparent bitmaps which are important for toggle buttons, for example.
This property will return a TQString::null if the button has no text. If the text has an ampersand (&) in it, then an accelerator is automatically created for it using the character that follows the '&' as the accelerator key. Any previous accelerator will be overwritten, or cleared if no accelerator is defined by the text.
