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

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

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

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