79 \class QRadioButton -
80 \brief The QRadioButton widget provides a radio button with a text label. -
81 -
82 \ingroup basicwidgets -
83 \inmodule QtWidgets -
84 -
85 A QRadioButton is an option button that can be switched on (checked) or -
86 off (unchecked). Radio buttons typically present the user with a "one -
87 of many" choice. In a group of radio buttons, only one radio button at -
88 a time can be checked; if the user selects another button, the -
89 previously selected button is switched off. -
90 -
91 Radio buttons are autoExclusive by default. If auto-exclusive is -
92 enabled, radio buttons that belong to the same parent widget -
93 behave as if they were part of the same exclusive button group. If -
94 you need multiple exclusive button groups for radio buttons that -
95 belong to the same parent widget, put them into a QButtonGroup. -
96 -
97 Whenever a button is switched on or off, it emits the toggled() signal. -
98 Connect to this signal if you want to trigger an action each time the -
99 button changes state. Use isChecked() to see if a particular button is -
100 selected. -
101 -
102 Just like QPushButton, a radio button displays text, and -
103 optionally a small icon. The icon is set with setIcon(). The text -
104 can be set in the constructor or with setText(). A shortcut key -
105 can be specified by preceding the preferred character with an -
106 ampersand in the text. For example: -
107 -
108 \snippet code/src_gui_widgets_qradiobutton.cpp 0 -
109 -
110 In this example the shortcut is \e{Alt+c}. See the \l -
111 {QShortcut#mnemonic}{QShortcut} documentation for details. To -
112 display an actual ampersand, use '&&'. -
113 -
114 Important inherited members: text(), setText(), text(), -
115 setDown(), isDown(), autoRepeat(), group(), setAutoRepeat(), -
116 toggle(), pressed(), released(), clicked(), and toggled(). -
