ProgressBar is actually a quite simple element, but it can be made quite interractive along with
After adding a console to your Render Tree, you just need to set a call-back:
// Add progressbar showing 0 (out of 100) $bar = ProgressBar::addTo($app); // Add with some other value of 20% and label $bar2 = ProgressBar::addTo($app, [20, '% Battery']);
$bar->value = 5; // sets this value instead of 0 Button::addTo($app, ['charge up the battery'])->on('click', $bar2->jsValue(100));
Updating Progress in RealTime¶
You can use real-time element such as jsSSE or Console (which relies on jsSSE) to execute jsValue() of your progress bar and adjust the display value.
