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

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

445 * If a callback function is passed it will be called after the user clicks either button, and the id of the
446 * button that was clicked will be passed as the only parameter to the callback (could also be the top-right close button).

466 * Displays a message box with OK and Cancel buttons prompting the user to enter some text (comparable to
467 * JavaScript's Window.prompt). The prompt can be a single-line or multi-line textbox. If a callback function
468 * is passed it will be called after the user clicks either button, and the id of the button that was clicked
469 * (could also be the top-right close button) and the text that was entered will be passed as the two
470 * parameters to the callback.
471 * @param {String} title The title bar text
472 * @param {String} msg The message box body text
473 * @param {Function} fn (optional) The callback function invoked after the message box is closed
474 * @param {Object} scope (optional) The scope of the callback function
475 * @param {Boolean/Number} multiline (optional) True to create a multiline textbox using the defaultTextHeight

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