It can also give the user an opportunity - to abort the operation. - - A common problem with progress dialogs is that it is difficult to know - when to use them; operations take different amounts of time on different - hardware. QProgressDialog offers a solution to this problem: - it estimates the time the operation will take (based on time for - steps), and only shows itself if that estimate is beyond minimumDuration() - (4 seconds by default). - - Use setMinimum() and setMaximum() or the constructor to set the number of - "steps" in the operation and call setValue() as the operation - progresses. The number of steps can be chosen arbitrarily. It can be the - number of files copied, the number of bytes received, the number of - iterations through the main loop of your algorithm, or some other - suitable unit. Progress starts at the value set by setMinimum(), - and the progress dialog shows that the operation has finished when - you call setValue() with the value set by setMaximum() as its argument. - - The dialog automatically resets and hides itself at the end of the - operation. Use setAutoReset() and setAutoClose() to change this - behavior. Note that if you set a new maximum (using setMaximum() or - setRange()) that equals your current value(), the dialog will not - close regardless. - - There are two ways of using QProgressDialog: modal and modeless. - - Compared to a modeless QProgressDialog, a modal QProgressDialog is simpler - to use for the programmer. Do the operation in a loop, call \l setValue() at - intervals, and check for cancellation with wasCanceled(). For example: - - \snippet doc/src/snippets/dialogs/dialogs.cpp 3 - - A modeless progress dialog is suitable for operations that take - place in the background, where the user is able to interact with the - application. Such operations are typically based on QTimer (or - QObject::timerEvent()), QSocketNotifier, or QUrlOperator; or performed - in a separate thread. A QProgressBar in the status bar of your main window - is often an alternative to a modeless progress dialog. - - You need to have an event loop to be running, connect the - canceled() signal to a slot that stops the operation, and call \l - setValue() at intervals. For example: - - \snippet doc/src/snippets/dialogs/dialogs.cpp 4 - \codeline - \snippet doc/src/snippets/dialogs/dialogs.cpp 5 - \codeline - \snippet doc/src/snippets/dialogs/dialogs.cpp 6 - - In both modes the progress dialog may be customized by - replacing the child widgets with custom widgets by using setLabel(), - setBar(), and setCancelButton(). - The functions setLabelText() and setCancelButtonText() - set the texts shown. - - \image plastique-progressdialog.png A progress dialog shown in the Plastique widget style. - - \sa QDialog, QProgressBar, {fowler}{GUI Design Handbook: Progress Indicator}, - {Find Files Example}, {Pixelator Example} -*/ - - -/*! - Constructs a progress dialog. - - Default settings: - \list - \i The label text is empty. - \i The cancel button text is (translated) "Cancel". - \i minimum is 0; - \i maximum is 100 - \endlist - - The \a parent argument is dialog's parent widget.
