59 \class QAbstractButton-
60-
61 \brief The QAbstractButton class is the abstract base class of-
62 button widgets, providing functionality common to buttons.-
63-
64 \ingroup abstractwidgets-
65 \inmodule QtWidgets-
66-
67 This class implements an \e abstract button.-
68 Subclasses of this class handle user actions, and specify how the button-
69 is drawn.-
70-
71 QAbstractButton provides support for both push buttons and checkable-
72 (toggle) buttons. Checkable buttons are implemented in the QRadioButton-
73 and QCheckBox classes. Push buttons are implemented in the-
74 QPushButton and QToolButton classes; these also provide toggle-
75 behavior if required.-
76-
77 Any button can display a label containing text and an icon. setText()-
78 sets the text; setIcon() sets the icon. If a button is disabled, its label-
79 is changed to give the button a "disabled" appearance.-
80-
81 If the button is a text button with a string containing an-
82 ampersand ('&'), QAbstractButton automatically creates a shortcut-
83 key. For example:-
84-
85 \snippet code/src_gui_widgets_qabstractbutton.cpp 0-
86-
87 The \uicontrol Alt+C shortcut is assigned to the button, i.e., when the-
88 user presses \uicontrol Alt+C the button will call animateClick(). See-
89 the \l {QShortcut#mnemonic}{QShortcut} documentation for details. To-
90 display an actual ampersand, use '&&'.-
91-
92 You can also set a custom shortcut key using the setShortcut()-
93 function. This is useful mostly for buttons that do not have any-
94 text, and therefore can't have any automatic shortcut.-
95-
96 \snippet code/src_gui_widgets_qabstractbutton.cpp 1-
97-
98 All the buttons provided by Qt (QPushButton, QToolButton,-
99 QCheckBox, and QRadioButton) can display both \l text and \l{icon}{icons}.-
100-
101 A button can be made the default button in a dialog by means of-
102 QPushButton::setDefault() and QPushButton::setAutoDefault().-
103-
104 QAbstractButton provides most of the states used for buttons:-
105-
106 \list-
107-
108 \li isDown() indicates whether the button is \e pressed down.-
109-
110 \li isChecked() indicates whether the button is \e checked. Only-
111 checkable buttons can be checked and unchecked (see below).-
112-
113 \li isEnabled() indicates whether the button can be pressed by the-
114 user. \note As opposed to other widgets, buttons derived from-
115 QAbstractButton accept mouse and context menu events-
116 when disabled.-
117-
118 \li setAutoRepeat() sets whether the button will auto-repeat if the-
119 user holds it down. \l autoRepeatDelay and \l autoRepeatInterval-
120 define how auto-repetition is done.-
121-
122 \li setCheckable() sets whether the button is a toggle button or not.-
123-
124 \endlist-
125-
126 The difference between isDown() and isChecked() is as follows.-
127 When the user clicks a toggle button to check it, the button is first-
128 \e pressed then released into the \e checked state. When the user-
129 clicks it again (to uncheck it), the button moves first to the-
130 \e pressed state, then to the \e unchecked state (isChecked() and-
131 isDown() are both false).-
132-
133 QAbstractButton provides four signals:-
134-
135 \list 1-
136-
137 \li pressed() is emitted when the left mouse button is pressed while-
138 the mouse cursor is inside the button.-
139-
140 \li released() is emitted when the left mouse button is released.-
141-
142 \li clicked() is emitted when the button is first pressed and then-
143 released, when the shortcut key is typed, or when click() or-
144 animateClick() is called.-
145-
146 \li toggled() is emitted when the state of a toggle button changes.-
147-
148 \endlist-
149-
150 To subclass QAbstractButton, you must reimplement at least-
151 paintEvent() to draw the button's outline and its text or pixmap. It-
152 is generally advisable to reimplement sizeHint() as well, and-
153 sometimes hitButton() (to determine whether a button press is within-
154 the button). For buttons with more than two states (like tri-state-
155 buttons), you will also have to reimplement checkStateSet() and-
156 nextCheckState().-

1231-
1232This may be the result of a user action, click() slot activation,-

1235The states of buttons in exclusive button groups are updated before this-

1240For example, a slot that reacts to signals emitted by newly checked-
1241buttons but which ignores signals from buttons that have been unchecked-
1242can be implemented using the following pattern:-

1244\snippet code/src_gui_widgets_qabstractbutton.cpp 2-
