/**
|
|
* 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) {...},
|
|
* 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/
