/** - * @class Ext.MessageBox - *

Utility class for generating different styles of message boxes. The alias Ext.Msg can also be used.

- *

Note that the MessageBox is asynchronous. Unlike a regular JavaScript alert (which will halt - * browser execution), showing a MessageBox will not cause the code to stop. For this reason, if you have code - * that should only run after some user feedback from the MessageBox, you must use a callback function - * (see the function parameter for {@link #show} for more details).

- *

Example usage:

- *

-// Basic alert:
-Ext.Msg.alert('Status', 'Changes saved successfully.');
-
-// Prompt for user data and process the result using a callback:
-Ext.Msg.prompt('Name', 'Please enter your name:', function(btn, text){
-    if (btn == 'ok'){
-        // process text value and close...
-    }
-});
-
-// Show a dialog using config options:
-Ext.Msg.show({
-   title:'Save Changes?',
-   msg: 'You are closing a tab that has unsaved changes. Would you like to save your changes?',
-   buttons: Ext.Msg.YESNOCANCEL,
-   fn: processResult,
-   animEl: 'elId',
-   icon: Ext.MessageBox.QUESTION
-});
