The TQProgressDialog class provides feedback on the progress of a slow operation.
< p > A progress dialog is used to give the user an indication of how long
an operation is going to take, and to demonstrate that the
application has not frozen. 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 );
tqApp-> < 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.

< / 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. If < em > modal< / em > is FALSE (the
default), you must have an event loop proceeding for any redrawing
of the dialog to occur. If < em > modal< / em > is TRUE, the dialog ensures that
events are processed when needed.

< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "labelText-prop" > < / a > labelText< / h3 >
< p > This property holds the label's text.
< p > The default text is < a href = "ntqstring.html#TQString-null" > TQString::null< / a > .
< p > Set this property's value with < a href = "#setLabelText" > setLabelText< / a > () and get this property's value with < a href = "#labelText" > labelText< / a > ().
< h3 class = fn > int < a name = "minimumDuration-prop" > < / a > minimumDuration< / h3 >
< p > This property holds the time that must pass before the dialog appears.
< p > If the expected duration of the task is less than the
minimumDuration, the dialog will not appear at all. This prevents
the dialog popping up for tasks that are quickly over. For tasks
that are expected to exceed the minimumDuration, the dialog will
pop up after the minimumDuration time or as soon as any progress
is set.
< p > If set to 0, the dialog is always shown as soon as any progress is
set. The default is 4000 milliseconds.
< p > Set this property's value with < a href = "#setMinimumDuration" > setMinimumDuration< / a > () and get this property's value with < a href = "#minimumDuration" > minimumDuration< / a > ().
< h3 class = fn > int < a name = "progress-prop" > < / a > progress< / h3 >
< p > This property holds the current amount of progress made.
< p > For the progress dialog to work as expected, you should initially set
this property to 0 and finally set it to
< a href = "#totalSteps" > TQProgressDialog::totalSteps< / a > (); you can call < a href = "#setProgress" > setProgress< / a > () any number of times
in-between.
< p > < b > Warning:< / b > If the progress dialog is modal
(see < a href = "#TQProgressDialog" > TQProgressDialog::TQProgressDialog< / a > ()),
this function calls < a href = "ntqapplication.html#processEvents" > TQApplication::processEvents< / a > (), so take care that
this does not cause undesirable re-entrancy in your code. For example,
don't use a TQProgressDialog inside a < a href = "ntqwidget.html#paintEvent" > paintEvent< / a > ()!
< p > < p > See also < a href = "#totalSteps-prop" > totalSteps< / a > .
< p > Set this property's value with < a href = "#setProgress" > setProgress< / a > () and get this property's value with < a href = "#progress" > progress< / a > ().
< h3 class = fn > int < a name = "totalSteps-prop" > < / a > totalSteps< / h3 >
< p > This property holds the total number of steps.
< p > The default is 0.
< p > Set this property's value with < a href = "#setTotalSteps" > setTotalSteps< / a > () and get this property's value with < a href = "#totalSteps" > totalSteps< / a > ().
< h3 class = fn > bool < a name = "wasCanceled-prop" > < / a > wasCanceled< / h3 >
< p > This property holds whether the dialog was canceled.
< p > Get this property's value with < a href = "#wasCanceled" > wasCanceled< / a > ().
< p > < p > See also < a href = "#progress-prop" > progress< / a > .
< h3 class = fn > bool < a name = "wasCancelled-prop" > < / a > wasCancelled< / h3 >
< p > This property holds whether the dialog was canceled.
< p > < b > This property is obsolete.< / b > It is provided to keep old source working. We strongly advise against using it in new code.
< p > Use < a href = "#wasCanceled-prop" > wasCanceled< / a > instead.
< p > Get this property's value with < a href = "#wasCancelled" > wasCancelled< / a > ().
