77 \class QPushButton -
78 \brief The QPushButton widget provides a command button. -
79 -
80 \ingroup basicwidgets -
81 \inmodule QtWidgets -
82 -
83 The push button, or command button, is perhaps the most commonly -
84 used widget in any graphical user interface. Push (click) a button -
85 to command the computer to perform some action, or to answer a -
86 question. Typical buttons are OK, Apply, Cancel, Close, Yes, No -
87 and Help. -
88 -
89 A command button is rectangular and typically displays a text -
90 label describing its action. A shortcut key can be specified by -
91 preceding the preferred character with an ampersand in the -
92 text. For example: -
93 -
94 \snippet code/src_gui_widgets_qpushbutton.cpp 0 -
95 -
96 In this example the shortcut is \e{Alt+D}. See the \l -
97 {QShortcut#mnemonic}{QShortcut} documentation for details (to -
98 display an actual ampersand, use '&&'). -
99 -
100 Push buttons display a textual label, and optionally a small -
101 icon. These can be set using the constructors and changed later -
102 using setText() and setIcon(). If the button is disabled, the -
103 appearance of the text and icon will be manipulated with respect -
104 to the GUI style to make the button look "disabled". -
105 -
106 A push button emits the signal clicked() when it is activated by -
107 the mouse, the Spacebar or by a keyboard shortcut. Connect to -
108 this signal to perform the button's action. Push buttons also -
109 provide less commonly used signals, for example pressed() and -
110 released(). -
111 -
112 Command buttons in dialogs are by default auto-default buttons, -
113 i.e., they become the default push button automatically when they -
114 receive the keyboard input focus. A default button is a push -
115 button that is activated when the user presses the Enter or Return -
116 key in a dialog. You can change this with setAutoDefault(). Note -
117 that auto-default buttons reserve a little extra space which is -
118 necessary to draw a default-button indicator. If you do not want -
119 this space around your buttons, call setAutoDefault(false). -
120 -
121 Being so central, the button widget has grown to accommodate a -
122 great many variations in the past decade. The Microsoft style -
123 guide now shows about ten different states of Windows push buttons -
124 and the text implies that there are dozens more when all the -
125 combinations of features are taken into consideration. -
126 -
127 The most important modes or states are: -
128 \list -
129 \li Available or not (grayed out, disabled). -
130 \li Standard push button, toggling push button or menu button. -
131 \li On or off (only for toggling push buttons). -
132 \li Default or normal. The default button in a dialog can generally -
133 be "clicked" using the Enter or Return key. -
134 \li Auto-repeat or not. -
135 \li Pressed down or not. -
136 \endlist -
137 -
138 As a general rule, use a push button when the application or -
139 dialog window performs an action when the user clicks on it (such -
140 as Apply, Cancel, Close and Help) \e and when the widget is -
141 supposed to have a wide, rectangular shape with a text label. -
142 Small, typically square buttons that change the state of the -
143 window rather than performing an action (such as the buttons in -
144 the top-right corner of the QFileDialog) are not command buttons, -
145 but tool buttons. Qt provides a special class (QToolButton) for -
146 these buttons. -
147 -
148 If you need toggle behavior (see setCheckable()) or a button -
149 that auto-repeats the activation signal when being pushed down -
150 like the arrows in a scroll bar (see setAutoRepeat()), a command -
151 button is probably not what you want. When in doubt, use a tool -
152 button. -
153 -
154 A variation of a command button is a menu button. These provide -
155 not just one command, but several, since when they are clicked -
156 they pop up a menu of options. Use the method setMenu() to -
157 associate a popup menu with a push button. -
158 -
159 Other classes of buttons are option buttons (see QRadioButton) and -
160 check boxes (see QCheckBox). -

164 \li A push button shown in the \l{Macintosh Style Widget Gallery}{Macintosh widget style}. -
165 -
166 Note that when a button's width becomes smaller than 50 or -
167 its height becomes smaller than 30, the button's corners are -
168 changed from round to square. Use the setMinimumSize() -
169 function to prevent this behavior. -

177 In Qt, the QAbstractButton base class provides most of the modes -
178 and other API, and QPushButton provides GUI logic. -
179 See QAbstractButton for more information about the API. -

185 \property QPushButton::autoDefault -
186 \brief whether the push button is an auto default button -
187 -
188 If this property is set to true then the push button is an auto -
189 default button. -
190 -
191 In some GUI styles a default button is drawn with an extra frame -
192 around it, up to 3 pixels or more. Qt automatically keeps this -
193 space free around auto-default buttons, i.e., auto-default buttons -
194 may have a slightly larger size hint. -
195 -
196 This property's default is true for buttons that have a QDialog -
197 parent; otherwise it defaults to false. -
198 -
199 See the \l default property for details of how \l default and -
200 auto-default interact. -
201*/ -
202 -
203/*! -
204 \property QPushButton::default -
205 \brief whether the push button is the default button -
206 -
207 Default and autodefault buttons decide what happens when the user -
208 presses enter in a dialog. -
209 -
210 A button with this property set to true (i.e., the dialog's -
211 \e default button,) will automatically be pressed when the user presses enter, -
212 with one exception: if an \a autoDefault button currently has focus, the autoDefault -
213 button is pressed. When the dialog has \l autoDefault buttons but no default button, -
214 pressing enter will press either the \l autoDefault button that currently has focus, or if no -
215 button has focus, the next \l autoDefault button in the focus chain. -
216 -
217 In a dialog, only one push button at a time can be the default -
218 button. This button is then displayed with an additional frame -
219 (depending on the GUI style). -
220 -
221 The default button behavior is provided only in dialogs. Buttons -
222 can always be clicked from the keyboard by pressing Spacebar when -
223 the button has focus. -
224 -
225 If the default property is set to false on the current default button -
226 while the dialog is visible, a new default will automatically be -
227 assigned the next time a push button in the dialog receives focus. -
228 -
229 This property's default is false. -
230*/ -
231 -
232/*! -
233 \property QPushButton::flat -
234 \brief whether the button border is raised -
235 -
236 This property's default is false. If this property is set, most -
237 styles will not paint the button background unless the button is -
238 being pressed. setAutoFillBackground() can be used to ensure that -
239 the background is filled using the QPalette::Button brush. -
