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

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

464 * is passed it will be called after the user clicks either button, and the id of the button that was clicked
465 * (could also be the top-right close button) and the text that was entered will be passed as the two
466 * parameters to the callback.
467 * @param {String} title The title bar text
468 * @param {String} msg The message box body text
469 * @param {Function} fn (optional) The callback function invoked after the message box is closed
470 * @param {Object} scope (optional) The scope of the callback function

528 * for setting a different minimum width than text-only dialogs may need (defaults to 250)
531 minProgressWidth : 250,
533 * An object containing the default button text strings that can be overriden for localized language support.
