75 \class QPushButton -

76 \brief The QPushButton widget provides a command button. -

77 -

78 \ingroup basicwidgets -

79 \inmodule QtWidgets -

80 -

81 The push button, or command button, is perhaps the most commonly -

82 used widget in any graphical user interface. Push (click) a button -

83 to command the computer to perform some action, or to answer a -

84 question. Typical buttons are OK, Apply, Cancel, Close, Yes, No -

85 and Help. -

86 -

87 A command button is rectangular and typically displays a text -

88 label describing its action. A shortcut key can be specified by -

89 preceding the preferred character with an ampersand in the -

90 text. For example: -

91 -

92 \snippet code/src_gui_widgets_qpushbutton.cpp 0 -

93 -

94 In this example the shortcut is \e{Alt+D}. See the \l -

95 {QShortcut#mnemonic}{QShortcut} documentation for details (to -

96 display an actual ampersand, use '&&'). -

97 -

98 Push buttons display a textual label, and optionally a small -

99 icon. These can be set using the constructors and changed later -

100 using setText() and setIcon(). If the button is disabled, the -

101 appearance of the text and icon will be manipulated with respect -

102 to the GUI style to make the button look "disabled". -

103 -

104 A push button emits the signal clicked() when it is activated by -

105 the mouse, the Spacebar or by a keyboard shortcut. Connect to -

106 this signal to perform the button's action. Push buttons also -

107 provide less commonly used signals, for example pressed() and -

108 released(). -

109 -

110 Command buttons in dialogs are by default auto-default buttons, -

111 i.e., they become the default push button automatically when they -

112 receive the keyboard input focus. A default button is a push -

113 button that is activated when the user presses the Enter or Return -

114 key in a dialog. You can change this with setAutoDefault(). Note -

115 that auto-default buttons reserve a little extra space which is -

116 necessary to draw a default-button indicator. If you do not want -

117 this space around your buttons, call setAutoDefault(false). -

118 -

119 Being so central, the button widget has grown to accommodate a -

120 great many variations in the past decade. The Microsoft style -

121 guide now shows about ten different states of Windows push buttons -

122 and the text implies that there are dozens more when all the -

123 combinations of features are taken into consideration. -

124 -

125 The most important modes or states are: -

126 \list -

127 \li Available or not (grayed out, disabled). -

128 \li Standard push button, toggling push button or menu button. -

129 \li On or off (only for toggling push buttons). -

130 \li Default or normal. The default button in a dialog can generally -

131 be "clicked" using the Enter or Return key. -

132 \li Auto-repeat or not. -

133 \li Pressed down or not. -

134 \endlist -

135 -

136 As a general rule, use a push button when the application or -

137 dialog window performs an action when the user clicks on it (such -

138 as Apply, Cancel, Close and Help) \e and when the widget is -

139 supposed to have a wide, rectangular shape with a text label. -

140 Small, typically square buttons that change the state of the -

141 window rather than performing an action (such as the buttons in -

142 the top-right corner of the QFileDialog) are not command buttons, -

143 but tool buttons. Qt provides a special class (QToolButton) for -

144 these buttons. -

145 -

146 If you need toggle behavior (see setCheckable()) or a button -

147 that auto-repeats the activation signal when being pushed down -

148 like the arrows in a scroll bar (see setAutoRepeat()), a command -

149 button is probably not what you want. When in doubt, use a tool -

150 button. -

151 -

152 A variation of a command button is a menu button. These provide -

153 not just one command, but several, since when they are clicked -

154 they pop up a menu of options. Use the method setMenu() to -

155 associate a popup menu with a push button. -

156 -

157 Other classes of buttons are option buttons (see QRadioButton) and -

158 check boxes (see QCheckBox). -

162 \li A push button shown in the \l{Macintosh Style Widget Gallery}{Macintosh widget style}. -

163 -

164 Note that when a button's width becomes smaller than 50 or -

165 its height becomes smaller than 30, the button's corners are -

166 changed from round to square. Use the setMinimumSize() -

167 function to prevent this behavior. -

174 -

175 In Qt, the QAbstractButton base class provides most of the modes -

176 and other API, and QPushButton provides GUI logic. -

177 See QAbstractButton for more information about the API. -

183 \property QPushButton::autoDefault -

184 \brief whether the push button is an auto default button -

185 -

186 If this property is set to true then the push button is an auto -

187 default button. -

188 -

189 In some GUI styles a default button is drawn with an extra frame -

190 around it, up to 3 pixels or more. Qt automatically keeps this -

191 space free around auto-default buttons, i.e., auto-default buttons -

192 may have a slightly larger size hint. -

193 -

194 This property's default is true for buttons that have a QDialog -

195 parent; otherwise it defaults to false. -

196 -

197 See the \l default property for details of how \l default and -

198 auto-default interact. -

200 -

201 /*! -

202 \property QPushButton::default -

203 \brief whether the push button is the default button -

204 -

205 Default and autodefault buttons decide what happens when the user -

206 presses enter in a dialog. -

207 -

208 A button with this property set to true (i.e., the dialog's -

209 \e default button,) will automatically be pressed when the user presses enter, -

210 with one exception: if an \a autoDefault button currently has focus, the autoDefault -

211 button is pressed. When the dialog has \l autoDefault buttons but no default button, -

212 pressing enter will press either the \l autoDefault button that currently has focus, or if no -

213 button has focus, the next \l autoDefault button in the focus chain. -

214 -

215 In a dialog, only one push button at a time can be the default -

216 button. This button is then displayed with an additional frame -

217 (depending on the GUI style). -

218 -

219 The default button behavior is provided only in dialogs. Buttons -

220 can always be clicked from the keyboard by pressing Spacebar when -

221 the button has focus. -

222 -

223 If the default property is set to false on the current default button -

224 while the dialog is visible, a new default will automatically be -

225 assigned the next time a push button in the dialog receives focus. -

226 -

227 This property's default is false. -

229 -

230 /*! -

231 \property QPushButton::flat -

232 \brief whether the button border is raised -

233 -

234 This property's default is false. If this property is set, most -

235 styles will not paint the button background unless the button is -

236 being pressed. setAutoFillBackground() can be used to ensure that -

237 the background is filled using the QPalette::Button brush. -
