|
|
|
|
|
|
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="tqapplication.html#processEvents">TQApplication::processEvents</a>() or
|
|
<a href="tqeventloop.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="tqapplication.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="tqtimer.html">TQTimer</a> (or
|
|
<a href="tqobject.html#timerEvent">TQObject::timerEvent</a>()), <a href="tqsocketnotifier.html">TQSocketNotifier</a>, or <a href="tqurloperator.html">TQUrlOperator</a>; or performed
|
|
in a separate thread. A <a href="tqprogressbar.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="tqobject.html">TQObject</a> *parent = 0 )
|
|
: <a href="tqobject.html">TQObject</a>( parent ), steps( 0 )
|
|
{
|
|
pd = new TQProgressDialog( "Operation in progress.", "Cancel", 100 );
|
|
<a href="tqobject.html#connect">connect</a>( pd, TQ_SIGNAL(<a href="#canceled">canceled</a>()), this, TQ_SLOT(<a href="#cancel">cancel</a>()) );
|
|
t = new <a href="tqtimer.html">TQTimer</a>( this );
|
|
<a href="tqobject.html#connect">connect</a>( t, TQ_SIGNAL(<a href="tqtimer.html#timeout">timeout</a>()), this, TQ_SLOT(perform()) );
|
|
t-><a href="tqtimer.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="tqtimer.html#stop">stop</a>();
|
|
}
|
|
|
|
void Operation::cancel()
|
|
{
|
|
t-><a href="tqtimer.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="tqdialog.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.
|
|
<p> <p>See also <a href="#labelText-prop">labelText</a>, <a href="#setLabel">setLabel</a>(), <a href="#setCancelButtonText">setCancelButtonText</a>(), <a href="#setCancelButton">setCancelButton</a>(), and <a href="#totalSteps-prop">totalSteps</a>.

|
</h3>
|
|
Constructs a progress dialog.
|
|
<p> The <em>labelText</em> is text used to remind the user what is progressing.
|
|
<p> The <em>cancelButtonText</em> is the text to display on the cancel button,
|
|
or 0 if no cancel button is to be shown.
|
|
<p> The <em>totalSteps</em> is the total number of steps in the operation for
|
|
which this progress dialog shows progress. For example, if the
|
|
operation is to examine 50 files, this value would be 50. Before
|
|
examining the first file, call <a href="#setProgress">setProgress</a>(0). As each file is
|
|
processed call setProgress(1), setProgress(2), etc., finally
|
|
calling setProgress(50) after examining the last file.
|
|
<p> The <em>creator</em> argument is the widget to use as the dialog's parent.
|
|
The <em>name</em>, <em>modal</em>, and widget flags, <em>f</em>, are passed to the
|
|
<a href="tqdialog.html#TQDialog">TQDialog::TQDialog</a>() constructor. If <em>modal</em> is FALSE (the default),
|
|
you will 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>bool <a name="autoClose-prop"></a>autoClose</h3>
|
|
<p>This property holds whether the dialog gets hidden by <a href="#reset">reset</a>().
|
|
<p>The default is TRUE.
|
|
<p> <p>See also <a href="#autoReset-prop">autoReset</a>.
|
|
|
|
<p>Set this property's value with <a href="#setAutoClose">setAutoClose</a>() and get this property's value with <a href="#autoClose">autoClose</a>().
|
|
<h3 class=fn>bool <a name="autoReset-prop"></a>autoReset</h3>
|
|
<p>This property holds whether the progress dialog calls <a href="#reset">reset</a>() as soon as <a href="#progress">progress</a>() equals <a href="#totalSteps">totalSteps</a>().
|
|
<p>The default is TRUE.
|
|
<p> <p>See also <a href="#autoClose-prop">autoClose</a>.
|
|
|
|
<p>Set this property's value with <a href="#setAutoReset">setAutoReset</a>() and get this property's value with <a href="#autoReset">autoReset</a>().
|
|
<h3 class=fn><a href="tqstring.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="tqstring.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="tqapplication.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="tqwidget.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>().
|
|

|
|
<p>This property holds whether the dialog was canceled.

|
|
|

|
|
<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>().
