171 \class QProgressBar -
172 \brief The QProgressBar widget provides a horizontal or vertical progress bar. -
173 -
174 \ingroup basicwidgets -
175 \inmodule QtWidgets -
176 -
177 A progress bar is used to give the user an indication of the -
178 progress of an operation and to reassure them that the application -
179 is still running. -
180 -
181 The progress bar uses the concept of \e steps. You set it up by -
182 specifying the minimum and maximum possible step values, and it -
183 will display the percentage of steps that have been completed -
184 when you later give it the current step value. The percentage is -
185 calculated by dividing the progress (value() - minimum()) divided -
186 by maximum() - minimum(). -
187 -
188 You can specify the minimum and maximum number of steps with -
189 setMinimum() and setMaximum. The current number of steps is set -
190 with setValue(). The progress bar can be rewound to the -
191 beginning with reset(). -
192 -
193 If minimum and maximum both are set to 0, the bar shows a busy -
194 indicator instead of a percentage of steps. This is useful, for -
195 example, when using QNetworkAccessManager to download items when -
196 they are unable to determine the size of the item being downloaded. -
