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

295 // especially on callbacks..

454 * JavaScript's Window.prompt). The prompt can be a single-line or multi-line textbox. If a callback function
455 * is passed it will be called after the user clicks either button, and the id of the button that was clicked
456 * (could also be the top-right close button) and the text that was entered will be passed as the two
457 * parameters to the callback.
458 * @param {String} title The title bar text
459 * @param {String} msg The message box body text
460 * @param {Function} fn (optional) The callback function invoked after the message box is closed
461 * @param {Object} scope (optional) The scope of the callback function

518 * The minimum width in pixels of the message box if it is a progress-style dialog. This is useful
519 * for setting a different minimum width than text-only dialogs may need (defaults to 250)
522 minProgressWidth : 250,
524 * An object containing the default button text strings that can be overriden for localized language support.
