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

1239This may be the result of a user action, click() slot activation,-

1242The states of buttons in exclusive button groups are updated before this-

1251\snippet code/src_gui_widgets_qabstractbutton.cpp 2-
