Radio buttons typically present the user with 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. - - Radio buttons are autoExclusive by default. If auto-exclusive is - enabled, radio buttons that belong to the same parent widget - behave as if they were part of the same exclusive button group. If - you need multiple exclusive button groups for radio buttons that - belong to the same parent widget, put them into a QButtonGroup. - - Whenever a button is switched on or off it emits the toggled() signal. - Connect to this signal if you want to trigger an action each time the - button changes state. Use isChecked() to see if a particular button is - selected. - - Just like QPushButton, a radio button displays text, and - optionally a small icon. The icon is set with setIcon(). The text - can be set in the constructor or with setText(). A shortcut key - can be specified by preceding the preferred character with an - ampersand in the text. For example: - - \snippet doc/src/snippets/code/src_gui_widgets_qradiobutton.cpp 0 - - In this example the shortcut is \e{Alt+c}. See the \l - {QShortcut#mnemonic}{QShortcut} documentation for details (to - display an actual ampersand, use '&&'). - - Important inherited members: text(), setText(), text(), - setDown(), isDown(), autoRepeat(), group(), setAutoRepeat(), - toggle(), pressed(), released(), clicked(), and toggled(). - - \table 100% - \row \o \inlineimage plastique-radiobutton.png Screenshot of a Plastique radio button - \o A radio button shown in the \l{Plastique Style Widget Gallery}{Plastique widget style}. - \row \o \inlineimage windows-radiobutton.png Screenshot of a Windows XP radio button - \o A radio button shown in the \l{Windows XP Style Widget Gallery}{Windows XP widget style}. - \row \o \inlineimage macintosh-radiobutton.png Screenshot of a Macintosh radio button - \o A radio button shown in the \l{Macintosh Style Widget Gallery}{Macintosh widget style}. - \endtable - - \sa QPushButton, QToolButton, QCheckBox, {fowler}{GUI Design Handbook: Radio Button}, - {Group Box Example} -*/ - - -/*! - Constructs a radio button with the given \a parent, but with no text or - pixmap. - - The \a parent argument is passed on to the QAbstractButton constructor. -*/ - -QRadioButton::QRadioButton(QWidget *parent) - : QAbstractButton(*new QRadioButtonPrivate, parent) -{ - Q_D(QRadioButton); - d->init(); -} - -/*! - Constructs a radio button with the given \a parent and a \a text string. - - The \a parent argument is passed on to the QAbstractButton constructor. -*/ - -QRadioButton::QRadioButton(const QString &text, QWidget *parent) - : QAbstractButton(*new QRadioButtonPrivate, parent) -{ - Q_D(QRadioButton); - d->init(); - setText(text); -} - -/*! - Initialize \a option with the values from this QRadioButton.
