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) {...}, * 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: * $j(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 * @see http://api.jqueryui.com/dialog/ */ var et2_dialog = et2_widget.extend({ attributes: { callback: { name: "Callback", type: "js", description: "Callback function is called with the value when the dialog is closed", "default": function(button_id) {egw.debug("log","Button ID: %d",button_id);} }, message: { name: "Message", type: "string", description: "Dialog message (plain text, no html)", "default": "Somebody forgot to set this...", }, dialog_type: { name: "Dialog type", type: "integer", description: "To use a pre-defined dialog style, use et2_dialog.ERROR_MESSAGE, INFORMATION_MESSAGE,WARNING_MESSAGE,QUESTION_MESSAGE,PLAIN_MESSAGE constants.
