69 \class QPushButton -

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

71 -

72 \ingroup basicwidgets -

73 \inmodule QtWidgets -

74 -

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

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

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

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

79 and Help. -

80 -

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

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

83 preceding the preferred character with an ampersand in the -

84 text. For example: -

85 -

86 \snippet code/src_gui_widgets_qpushbutton.cpp 0 -

87 -

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

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

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

91 -

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

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

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

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

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

97 -

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

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

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

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

102 released(). -

103 -

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

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

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

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

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

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

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

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

112 -

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

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

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

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

117 combinations of features are taken into consideration. -

118 -

119 The most important modes or states are: -

120 \list -

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

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

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

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

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

126 \li Auto-repeat or not. -

127 \li Pressed down or not. -

128 \endlist -

129 -

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

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

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

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

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

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

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

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

138 these buttons. -

139 -

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

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

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

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

144 button. -

145 -

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

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

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

149 associate a popup menu with a push button. -

150 -

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

152 check boxes (see QCheckBox). -

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

157 -

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

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

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

161 function to prevent this behavior. -

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

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

171 See QAbstractButton for more information about the API. -

177 \property QPushButton::autoDefault -

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

179 -

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

181 default button. -

182 -

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

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

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

186 may have a slightly larger size hint. -

187 -

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

189 parent; otherwise it defaults to false. -

190 -

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

192 auto-default interact. -

193 */ -

194 -

195 /*! -

196 \property QPushButton::default -

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

198 -

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

200 presses enter in a dialog. -

201 -

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

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

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

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

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

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

208 -

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

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

211 (depending on the GUI style). -

212 -

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

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

215 the button has focus. -

216 -

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

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

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

220 -

221 This property's default is false. -

223 -

224 /*! -

225 \property QPushButton::flat -

226 \brief whether the button border is raised -

227 -

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

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

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

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