223 * Displays a new message box, or reinitializes an existing message box, based on the config options
224 * passed in. All functions (e.g. prompt, alert, etc) on MessageBox call this function internally.
225 * The following config object properties are supported:
227 Property Type Description
228 ---------- --------------- ------------------------------------------------------------------------------------
229 animEl String/Element An id or Element from which the message box should animate as it opens and
230 closes (defaults to undefined)
231 buttons Object/Boolean A button config object (e.g., Roo.MessageBox.OKCANCEL or {ok:'Foo',
232 cancel:'Bar'}), or false to not show any buttons (defaults to false)
233 closable Boolean False to hide the top-right close button (defaults to true). Note that
234 progress and wait dialogs will ignore this property and always hide the
235 close button as they can only be closed programmatically.
236 cls String A custom CSS class to apply to the message box element
237 defaultTextHeight Number The default height in pixels of the message box's multiline textarea if
238 displayed (defaults to 75)
239 fn Function A callback function to execute after closing the dialog. The arguments to the
240 function will be btn (the name of the button that was clicked, if applicable,
241 e.g. "ok"), and text (the value of the active text field, if applicable).
242 Progress and wait dialogs will ignore this option since they do not respond to
243 user actions and can only be closed programmatically, so any required function
244 should be called by the same code after it closes the dialog.
245 icon String A CSS class that provides a background image to be used as an icon for
246 the dialog (e.g., Roo.MessageBox.WARNING or 'custom-class', defaults to '')
247 maxWidth Number The maximum width in pixels of the message box (defaults to 600)
248 minWidth Number The minimum width in pixels of the message box (defaults to 100)
249 modal Boolean False to allow user interaction with the page while the message box is
250 displayed (defaults to true)
251 msg String A string that will replace the existing message box body text (defaults
252 to the XHTML-compliant non-breaking space character ' ')
253 multiline Boolean True to prompt the user to enter multi-line text (defaults to false)
254 progress Boolean True to display a progress bar (defaults to false)
255 progressText String The text to display inside the progress bar if progress = true (defaults to '')
256 prompt Boolean True to prompt the user to enter single-line text (defaults to false)
257 proxyDrag Boolean True to display a lightweight proxy while dragging (defaults to false)
258 title String The title text
259 value String The string value to set into the active textbox element if displayed
260 wait Boolean True to display a progress bar (defaults to false)
261 width Number The width of the dialog in pixels
268 msg: 'Please enter your address:',
270 buttons: Roo.MessageBox.OKCANCEL,
273 animEl: 'addAddressBtn'
276 * @param {Object} config Configuration options
277 * @return {Roo.MessageBox} This message box
279 show : function(options)
282 // this causes nightmares if you show one dialog after another
283 // especially on callbacks..

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

369 * id of the button that was clicked will be passed as the only parameter to the callback
370 * (could also be the top-right close button).
371 * @param {String} title The title bar text

391 * interaction while waiting for a long-running process to complete that does not have defined intervals.
392 * You are responsible for closing the message box when the process is complete.
393 * @param {String} msg The message box body text

419 * If a callback function is passed it will be called after the user clicks either button, and the id of the
420 * button that was clicked will be passed as the only parameter to the callback (could also be the top-right close button).
421 * @param {String} title The title bar text
422 * @param {String} msg The message box body text
423 * @param {Function} fn (optional) The callback function invoked after the message box is closed

427 confirm : function(title, msg, fn, scope){
440 * Displays a message box with OK and Cancel buttons prompting the user to enter some text (comparable to
441 * JavaScript's Window.prompt). The prompt can be a single-line or multi-line textbox. If a callback function
442 * is passed it will be called after the user clicks either button, and the id of the button that was clicked
443 * (could also be the top-right close button) and the text that was entered will be passed as the two
444 * parameters to the callback.
445 * @param {String} title The title bar text
446 * @param {String} msg The message box body text
447 * @param {Function} fn (optional) The callback function invoked after the message box is closed
448 * @param {Object} scope (optional) The scope of the callback function
449 * @param {Boolean/Number} multiline (optional) True to create a multiline textbox using the defaultTextHeight

500 * The minimum width in pixels of the message box (defaults to 100)
505 * The minimum width in pixels of the message box if it is a progress-style dialog. This is useful
506 * for setting a different minimum width than text-only dialogs may need (defaults to 250)
509 minProgressWidth : 250,
511 * An object containing the default button text strings that can be overriden for localized language support.
512 * Supported properties are: ok, cancel, yes and no.
