231 * Displays a new message box, or reinitializes an existing message box, based on the config options
232 * passed in. All functions (e.g. prompt, alert, etc) on MessageBox call this function internally.
233 * The following config object properties are supported:
235 Property Type Description
236 ---------- --------------- ------------------------------------------------------------------------------------
237 animEl String/Element An id or Element from which the message box should animate as it opens and
238 closes (defaults to undefined)
239 buttons Object/Boolean A button config object (e.g., Roo.MessageBox.OKCANCEL or {ok:'Foo',
240 cancel:'Bar'}), or false to not show any buttons (defaults to false)
241 closable Boolean False to hide the top-right close button (defaults to true). Note that
242 progress and wait dialogs will ignore this property and always hide the
243 close button as they can only be closed programmatically.
244 cls String A custom CSS class to apply to the message box element
245 defaultTextHeight Number The default height in pixels of the message box's multiline textarea if
246 displayed (defaults to 75)
247 fn Function A callback function to execute after closing the dialog. The arguments to the
248 function will be btn (the name of the button that was clicked, if applicable,
249 e.g. "ok"), and text (the value of the active text field, if applicable).
250 Progress and wait dialogs will ignore this option since they do not respond to
251 user actions and can only be closed programmatically, so any required function
252 should be called by the same code after it closes the dialog.
253 icon String A CSS class that provides a background image to be used as an icon for
254 the dialog (e.g., Roo.MessageBox.WARNING or 'custom-class', defaults to '')
255 maxWidth Number The maximum width in pixels of the message box (defaults to 600)
256 minWidth Number The minimum width in pixels of the message box (defaults to 100)
257 modal Boolean False to allow user interaction with the page while the message box is
258 displayed (defaults to true)
259 msg String A string that will replace the existing message box body text (defaults
260 to the XHTML-compliant non-breaking space character ' ')
261 multiline Boolean True to prompt the user to enter multi-line text (defaults to false)
262 progress Boolean True to display a progress bar (defaults to false)
263 progressText String The text to display inside the progress bar if progress = true (defaults to '')
264 prompt Boolean True to prompt the user to enter single-line text (defaults to false)
265 proxyDrag Boolean True to display a lightweight proxy while dragging (defaults to false)
266 title String The title text
267 value String The string value to set into the active textbox element if displayed
268 wait Boolean True to display a progress bar (defaults to false)
269 width Number The width of the dialog in pixels
276 msg: 'Please enter your address:',
278 buttons: Roo.MessageBox.OKCANCEL,
281 animEl: 'addAddressBtn'
284 * @param {Object} config Configuration options
285 * @return {Roo.MessageBox} This message box
287 show : function(options)

291 // especially on callbacks..

355 * Displays a message box with a progress bar. This message box has no buttons and is not closeable by

449 * Displays a message box with OK and Cancel buttons prompting the user to enter some text (comparable to
450 * JavaScript's Window.prompt). The prompt can be a single-line or multi-line textbox. If a callback function
451 * is passed it will be called after the user clicks either button, and the id of the button that was clicked
452 * (could also be the top-right close button) and the text that was entered will be passed as the two
453 * parameters to the callback.
454 * @param {String} title The title bar text
455 * @param {String} msg The message box body text
456 * @param {Function} fn (optional) The callback function invoked after the message box is closed
