161 \class QStatusBar -

162 \brief The QStatusBar class provides a horizontal bar suitable for -

163 presenting status information. -

164 -

165 \ingroup mainwindow-classes -

166 \ingroup helpsystem -

167 \inmodule QtWidgets -

168 -

169 Each status indicator falls into one of three categories: -

170 -

171 \list -

172 \li \e Temporary - briefly occupies most of the status bar. Used -

173 to explain tool tip texts or menu entries, for example. -

174 \li \e Normal - occupies part of the status bar and may be hidden -

175 by temporary messages. Used to display the page and line -

176 number in a word processor, for example. -

177 \li \e Permanent - is never hidden. Used for important mode -

178 indications, for example, some applications put a Caps Lock -

179 indicator in the status bar. -

180 \endlist -

181 -

182 QStatusBar lets you display all three types of indicators. -

183 -

184 Typically, a request for the status bar functionality occurs in -

185 relation to a QMainWindow object. QMainWindow provides a main -

186 application window, with a menu bar, tool bars, dock widgets \e -

187 and a status bar around a large central widget. The status bar can -

188 be retrieved using the QMainWindow::statusBar() function, and -

189 replaced using the QMainWindow::setStatusBar() function. -

190 -

191 Use the showMessage() slot to display a \e temporary message: -

192 -

193 \snippet mainwindows/dockwidgets/mainwindow.cpp 8 -

194 -

195 To remove a temporary message, use the clearMessage() slot, or set -

196 a time limit when calling showMessage(). For example: -

197 -

198 \snippet mainwindows/dockwidgets/mainwindow.cpp 3 -

199 -

200 Use the currentMessage() function to retrieve the temporary -

201 message currently shown. The QStatusBar class also provide the -

202 messageChanged() signal which is emitted whenever the temporary -

203 status message changes. -

204 -

205 \target permanent message -

206 \e Normal and \e Permanent messages are displayed by creating a -

207 small widget (QLabel, QProgressBar or even QToolButton) and then -

208 adding it to the status bar using the addWidget() or the -

209 addPermanentWidget() function. Use the removeWidget() function to -

210 remove such messages from the status bar. -

211 -

212 \snippet code/src_gui_widgets_qstatusbar.cpp 0 -

213 -

214 By default QStatusBar provides a QSizeGrip in the lower-right -

215 corner. You can disable it using the setSizeGripEnabled() -

216 function. Use the isSizeGripEnabled() function to determine the -

217 current status of the size grip. -
