- * @class Ext.ProgressBar\r
- * @extends Ext.BoxComponent\r
- * <p>An updateable progress bar component. The progress bar supports two different modes: manual and automatic.</p>\r
- * <p>In manual mode, you are responsible for showing, updating (via {@link #updateProgress}) and clearing the\r
- * progress bar as needed from your own code. This method is most appropriate when you want to show progress\r
- * throughout an operation that has predictable points of interest at which you can update the control.</p>\r
- * <p>In automatic mode, you simply call {@link #wait} and let the progress bar run indefinitely, only clearing it\r
- * once the operation is complete. You can optionally have the progress bar wait for a specific amount of time\r
- * and then clear itself. Automatic mode is most appropriate for timed operations or asynchronous operations in\r
- * which you have no need for indicating intermediate progress.</p>\r

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