It can also give the user an opportunity +to abort the operation. +<p> 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. TQProgressDialog 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 <a href="#minimumDuration">minimumDuration</a>() +(4 seconds by default). +<p> Use <a href="#setTotalSteps">setTotalSteps</a>() (or the constructor) to set the number of +"steps" in the operation and call <a href="#setProgress">setProgress</a>() as the operation +progresses. The step value 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 0, and the progress dialog shows +that the operation has finished when you call setProgress() with +<a href="#totalSteps">totalSteps</a>() as its argument. +<p> The dialog automatically resets and hides itself at the end of the +operation. Use <a href="#setAutoReset">setAutoReset</a>() and <a href="#setAutoClose">setAutoClose</a>() to change this +behavior. +<p> There are two ways of using TQProgressDialog: modal and modeless. +<p> Using a modal TQProgressDialog is simpler for the programmer, but you +must call <a href="ntqapplication.html#processEvents">TQApplication::processEvents</a>() or +<a href="ntqeventloop.html#processEvents">TQEventLoop::processEvents</a>(ExcludeUserInput) to keep the event loop +running to ensure that the application doesn't freeze. Do the +operation in a loop, call <a href="#setProgress">setProgress</a>() at intervals, and check +for cancellation with <a href="#wasCanceled">wasCanceled</a>(). For example: +<pre> +TQProgressDialog progress( "Copying files...", "Abort Copy", numFiles, + this, "progress", TRUE ); +for ( int i = 0; i < numFiles; i++ ) { + progress.setProgress( i ); + qApp-><a href="ntqapplication.html#processEvents">processEvents</a>(); + + if ( progress.wasCanceled() ) + break; + //... copy one file +} +progress.setProgress( numFiles ); +</pre> + +<p> 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 <a href="ntqtimer.html">TQTimer</a> (or +<a href="ntqobject.html#timerEvent">TQObject::timerEvent</a>()), <a href="ntqsocketnotifier.html">TQSocketNotifier</a>, or <a href="ntqurloperator.html">TQUrlOperator</a>; or performed +in a separate thread. A <a href="ntqprogressbar.html">TQProgressBar</a> in the status bar of your main window +is often an alternative to a modeless progress dialog. +<p> You need to have an event loop to be running, connect the +<a href="#canceled">canceled</a>() signal to a slot that stops the operation, and call <a href="#setProgress">setProgress</a>() at intervals. For example: +<pre> +Operation::Operation( <a href="ntqobject.html">TQObject</a> *parent = 0 ) + : <a href="ntqobject.html">TQObject</a>( parent ), steps( 0 ) +{ + pd = new TQProgressDialog( "Operation in progress.", "Cancel", 100 ); + <a href="ntqobject.html#connect">connect</a>( pd, SIGNAL(<a href="#canceled">canceled</a>()), this, SLOT(<a href="#cancel">cancel</a>()) ); + t = new <a href="ntqtimer.html">TQTimer</a>( this ); + <a href="ntqobject.html#connect">connect</a>( t, SIGNAL(<a href="ntqtimer.html#timeout">timeout</a>()), this, SLOT(perform()) ); + t-><a href="ntqtimer.html#start">start</a>( 0 ); +} + +void Operation::perform() +{ + pd-><a href="#setProgress">setProgress</a>( steps ); + //... perform one percent of the operation + steps++; + if ( steps > pd-><a href="#totalSteps">totalSteps</a>() ) + t-><a href="ntqtimer.html#stop">stop</a>(); +} + +void Operation::cancel() +{ + t-><a href="ntqtimer.html#stop">stop</a>(); + //... cleanup +} +</pre> + +<p> In both modes the progress dialog may be customized by +replacing the child widgets with custom widgets by using <a href="#setLabel">setLabel</a>(), +<a href="#setBar">setBar</a>(), and <a href="#setCancelButton">setCancelButton</a>(). +The functions <a href="#setLabelText">setLabelText</a>() and <a href="#setCancelButtonText">setCancelButtonText</a>() +set the texts shown. +<p> <img src=qprogdlg-m.png> <img src=qprogdlg-w.png> +<p> <p>See also <a href="ntqdialog.html">TQDialog</a>, <a href="ntqprogressbar.html">TQProgressBar</a>, <a href="guibooks.html#fowler">GUI Design Handbook: Progress Indicator</a>, and <a href="dialogs.html">Dialog Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQProgressDialog"></a>TQProgressDialog::TQProgressDialog ( <a href="ntqwidget.html">TQWidget</a> * creator = 0, const char * name = 0, bool modal = FALSE, WFlags f = 0 ) +</h3> +Constructs a progress dialog. +<p> Default settings: +<ul> +<li> The label text is empty. +<li> The cancel button text is (translated) "Cancel". +<li> The total number of steps is 100. +</ul> +<p> The <em>creator</em> argument is the widget to use as the dialog's parent. +The <em>name</em>, <em>modal</em>, and the widget flags, <em>f</em>, are +passed to the <a href="ntqdialog.html#TQDialog">TQDialog::TQDialog</a>() constructor.
