GtkProgressBar Constructor

Creates a new progress bar.

Using the optional parameter is deprecated.

Example 106. Using a GtkProgressBar

<?php
//Example for the two progress bar modes:
// continuous and pulsing
 
$window = new GtkWindow();
$window->connect_simple('destroy', array('Gtk', 'main_quit'));
$vbox = new GtkVBox();
 
$vbox->pack_start(new GtkLabel('Normal:'), false);
 
//Create a new continuous progress bar
$normal = new GtkProgressBar();
//Add it to the vbox
$vbox->pack_start($normal);
 
 
$vbox->pack_start(new GtkLabel('Pulsing:'), false);
 
//Create a pulsing progress bar
$pulsing = new GtkProgressBar();
//Set the step size the pulse should go on each update
$pulsing->set_pulse_step(0.1);
//Add it to the vbox
$vbox->pack_start($pulsing);
 
 
function update(GtkProgressBar $normal, GtkProgressBar $pulsing) {
    //Since the "pulsing" mode doesn't have any fixed values,
    // all we need to call is this method.
    $pulsing->pulse();
 
    //The normal mode needs a certain value to be set.
    // Here we add 10% to the current value, resetting
    // it to 0 when it reaches 110% (so that we get a nice
    // animation)
    $normal->set_fraction(
        (($normal->get_fraction() * 10 + 1) % 11) / 10
    );
    //Setting the text to the current percentage
    $normal->set_text(
        ($normal->get_fraction() * 100) . '%'
    );
 
    //Keep the timeout running. When not returning true,
    //it stops.
    return true;
}
 
//A timeout to be called every 200 milliseconds that updates
// the progress bar
Gtk::timeout_add(200, 'update', $normal, $pulsing);
 
 
//add the progress bar to the window
$window->add($vbox);
 
$window->show_all();
Gtk::main();
?>
