- * @class Ext.ProgressBar
- * @extends Ext.BoxComponent
- * <p>An updateable progress bar component. The progress bar supports two different modes: manual and automatic.</p>
- * <p>In manual mode, you are responsible for showing, updating (via {@link #updateProgress}) and clearing the
- * progress bar as needed from your own code. This method is most appropriate when you want to show progress
- * throughout an operation that has predictable points of interest at which you can update the control.</p>
- * <p>In automatic mode, you simply call {@link #wait} and let the progress bar run indefinitely, only clearing it
- * once the operation is complete. You can optionally have the progress bar wait for a specific amount of time
- * and then clear itself. Automatic mode is most appropriate for timed operations or asynchronous operations in
- * which you have no need for indicating intermediate progress.</p>
- * @cfg {Float} value A floating point value between 0 and 1 (e.g., .5, defaults to 0)
- * @cfg {String} text The progress bar text (defaults to '')
- * @cfg {Mixed} textEl The element to render the progress text to (defaults to the progress
- * bar's internal text element)
- * @cfg {String} id The progress bar element's id (defaults to an auto-generated id)
- * @xtype progress

- * Initiates an auto-updating progress bar. A duration can be specified, in which case the progress

- * be manually cleared by calling {@link #reset}. The wait method accepts a config object with
- * the following properties:
- * <pre>
-Property Type Description
----------- ------------ ----------------------------------------------------------------------
-duration Number The length of time in milliseconds that the progress bar should
- run before resetting itself (defaults to undefined, in which case it
- will run indefinitely until reset is called)
-interval Number The length of time in milliseconds between each progress update
- (defaults to 1000 ms)
-animate Boolean Whether to animate the transition of the progress bar. If this value is
- not specified, the default for the class is used.
-increment Number The number of progress update segments to display within the progress
- bar (defaults to 10). If the bar reaches the end and is still
- updating, it will automatically wrap back to the beginning.
-text String Optional text to display in the progress bar element (defaults to '').
-fn Function A callback function to execute after the progress bar finishes auto-
- updating. The function will be called with no arguments. This function
- will be ignored if duration is not specified since in that case the
- progress bar can only be stopped programmatically, so any required function
- should be called by the same code after it resets the progress bar.
-scope Object The scope that is passed to the callback function (only applies when
- duration and fn are both passed).
-</pre>
- *
- * Example usage:
- * <pre><code>
-var p = new Ext.ProgressBar({
- renderTo: 'my-el'
-});
+Ext.define('Ext.layout.component.ProgressBar', {
-//Wait for 5 seconds, then update the status el (progress bar will auto-reset)
-p.wait({
- interval: 100, //bar will move fast!
- duration: 5000,
- increment: 15,
- text: 'Updating...',
- scope: this,
- fn: function(){
- Ext.fly('status').update('Done!');
- }
-});
+ /* Begin Definitions */
-//Or update indefinitely until some async action completes, then reset manually
-p.wait();
-myAction.on('complete', function(){
- p.reset();
- Ext.fly('status').update('Done!');
-});
