/**
* A common dialog widget that makes it easy to imform users or prompt for information.
*
* It is possible to have a custom dialog by using a template, but you can also use
* the static method et2_dialog.show_dialog(). At its simplest, you can just use:
* <code>
* et2_dialog.show_dialog(false, "Operation completed");
* </code>
* Or a more complete example:
* <code>
* var callback = function (button_id)
* {
* if(button_id == et2_dialog.YES_BUTTON)
* {
* // Do stuff
* }
* else if (button_id == et2_dialog.NO_BUTTON)
* {
* // Other stuff
* }
* else if (button_id == et2_dialog.CANCEL_BUTTON)
* {
* // Abort
* }
* }.
* var dialog = et2_dialog.show_dialog(
* callback, "Erase the entire database?","Break things", {} // value
* et2_dialog.BUTTONS_YES_NO_CANCEL, et2_dialog.WARNING_MESSAGE
* );
* </code>
*
*
* The parameters for the above are all optional, except callback and message:
* callback - function called when the dialog closes, or false/null.
* The ID of the button will be passed. Button ID will be one of the et2_dialog.*_BUTTON constants.
* The callback is _not_ called if the user closes the dialog with the X in the corner, or presses ESC.
* message - (plain) text to display
* title - Dialog title
* value (for prompt)
* buttons - et2_dialog BUTTONS_* constant, or an array of button settings
* dialog_type - et2_dialog *_MESSAGE constant
* icon - URL of icon
*
* Note that these methods will _not_ block program flow while waiting for user input.
* The user's input will be provided to the callback.
*
* You can also use the standard et2_createWidget() to create a custom dialog using an etemplate, even setting all
* the buttons yourself.
* <code>
* var dialog = et2_createWidget("dialog",{
* // If you use a template, the second parameter will be the value of the template, as if it were submitted.
* callback: function(button_id, value) {...}, // return false to prevent dialog closing
* buttons: [
* // These ones will use the callback, just like normal
* {text: egw.lang("OK"),id:"OK", class="ui-priority-primary", default: true},
* {text: egw.lang("Yes"),id:"Yes"},
* {text: egw.lang("Sure"),id:"Sure"},
* {text: egw.lang("Maybe"),click: function() {
* // If you override, 'this' will be the dialog DOMNode.
* // Things get more complicated.
* // Do what you like, but don't forget this line:
* jQuery(this).dialog("close")
* }, class="ui-state-error"},
*
* ],
* title: 'Why would you want to do this?',
* template:"/egroupware/addressbook/templates/default/edit.xet",
* value: { content: {...default values}, sel_options: {...}...}
* });
* </code>
* @augments et2_widget
