// @define Ext.MessageBox, Ext.Msg
/**
* Utility class for generating different styles of message boxes. The singleton instance, Ext.MessageBox
* alias `Ext.Msg` can also be used.
*
* Note that a 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 #method-show} for more details).
*
* Basic alert
*
* @example
* Ext.Msg.alert('Status', 'Changes saved successfully.');
*
* Prompt for user data and process the result using a callback
*
* @example
* 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
*
* @example
* 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,
* icon: Ext.Msg.QUESTION
* });

/**
* Displays a new message box, or reinitializes an existing message box, based on the config options passed in. All
* display functions (e.g. prompt, alert, etc.) on MessageBox call this function internally, although those calls
* are basic shortcuts and do not support all of the config options allowed here.
*
* Example usage:
*
* Ext.Msg.show({
* title: 'Address',
* msg: 'Please enter your address:',
* width: 300,
* buttons: Ext.Msg.OKCANCEL,
* multiline: true,
* fn: saveAddress,
* animateTarget: 'addAddressBtn',
* icon: Ext.window.MessageBox.INFO
* });
*
* @param {Object} config The following config options are supported:
*
* @param {String/Ext.dom.Element} config.animateTarget
* An id or Element from which the message box should animate as it opens and closes.
*
* @param {Number} [config.buttons=false]
* A bitwise button specifier consisting of the sum of any of the following constants:
*
* - Ext.MessageBox.OK
* - Ext.MessageBox.YES
* - Ext.MessageBox.NO
* - Ext.MessageBox.CANCEL
*
* Some common combinations have already been predefined:
*
* - Ext.MessageBox.OKCANCEL
* - Ext.MessageBox.YESNO
* - Ext.MessageBox.YESNOCANCEL
*
* Or false to not show any buttons.
*
* This may also be specified as an object hash containing custom button text in the same format as the
* {@link #buttonText} config. Button IDs present as property names will be made visible.
*
* @param {Boolean} config.closable
* False to hide the top-right close button (defaults to true). Note that progress and wait dialogs will ignore this
* property and always hide the close button as they can only be closed programmatically.
*
* @param {String} config.cls
* A custom CSS class to apply to the message box's container element
*
* @param {Number} [config.defaultTextHeight=75]
* The default height in pixels of the message box's multiline textarea if displayed.
*
* @param {Function} config.fn
* A callback function which is called when the dialog is dismissed either by clicking on the configured buttons, or
* on the dialog close button, or by pressing the return button to enter input.
*
* Progress and wait dialogs will ignore this option since they do not respond to user actions and can only be
* closed programmatically, so any required function should be called by the same code after it closes the dialog.
* Parameters passed:
*
* @param {String} config.fn.buttonId The ID of the button pressed, one of:
*
* - ok
* - yes
* - no
* - cancel
*
* @param {String} config.fn.text Value of the input field if either `prompt` or `multiline` is true
* @param {Object} config.fn.opt The config object passed to show.
*
* @param {Object} config.buttonText
* An object containing string properties which override the system-supplied button text values just for this
* invocation. The property names are:
*
* - ok
* - yes
* - no
* - cancel
*
* @param {Object} config.scope
* The scope (`this` reference) in which the function will be executed.
*
* @param {String} config.icon
* A CSS class that provides a background image to be used as the body icon for the dialog.
* One can use a predefined icon class:
*
* - Ext.MessageBox.INFO
* - Ext.MessageBox.WARNING
* - Ext.MessageBox.QUESTION
* - Ext.MessageBox.ERROR
*
* or use just any `'custom-class'`. Defaults to empty string.
*
* @param {String} config.iconCls
* The standard {@link Ext.window.Window#iconCls} to add an optional header icon (defaults to '')
*
* @param {String} config.defaultFocus
* The button to focus when showing the dialog. If not specified, defaults to
* the first visible button.
*
* @param {Number} config.maxWidth
* The maximum width in pixels of the message box (defaults to 600)
*
* @param {Number} config.minWidth
* The minimum width in pixels of the message box (defaults to 100)
*
* @param {Boolean} config.modal
* False to allow user interaction with the page while the message box is displayed (defaults to true)
*
* @param {String} config.msg
* A string that will replace the existing message box body text (defaults to the XHTML-compliant non-breaking space
* character ' ')
*
* @param {Boolean} config.multiline
* True to prompt the user to enter multi-line text (defaults to false)
*
* @param {Boolean} config.progress
* True to display a progress bar (defaults to false)
*
* @param {String} config.progressText
* The text to display inside the progress bar if progress = true (defaults to '')
*
* @param {Boolean} config.prompt
* True to prompt the user to enter single-line text (defaults to false)
*
* @param {Boolean} config.proxyDrag
* True to display a lightweight proxy while dragging (defaults to false)
*
* @param {String} config.title
* The title text
*
* @param {String} config.value
* The string value to set into the active textbox element if displayed
*
* @param {Boolean} config.wait
* True to display a progress bar (defaults to false)
*
* @param {Object} config.waitConfig
* A {@link Ext.ProgressBar#wait} config object (applies only if wait = true)
*
* @param {Number} config.width
* The width of the dialog in pixels
*
* @return {Ext.window.MessageBox} this
