An updateable progress bar component. The progress bar supports two different modes: manual and automatic.
- *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.
- *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.
- * @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 - */ -Ext.ProgressBar = Ext.extend(Ext.BoxComponent, { - /** - * @cfg {String} baseCls - * The base CSS class to apply to the progress bar's wrapper element (defaults to 'x-progress') - */ - baseCls : 'x-progress', - - /** - * @cfg {Boolean} animate - * True to animate the progress bar during transitions (defaults to false) - */ - animate : false, - - // private - waitTimer : null, - - // private - initComponent : function(){ - Ext.ProgressBar.superclass.initComponent.call(this); - this.addEvents( - /** - * @event update - * Fires after each update interval - * @param {Ext.ProgressBar} this - * @param {Number} The current progress value - * @param {String} The current progress text - */ - "update" - ); - }, - - // private - onRender : function(ct, position){ - var tpl = new Ext.Template( - '-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.
