Container Release Notes
*** version 2.3.0 ***
Fixed the following bugs:
-------------------------
+ Improved creation of the <iframe> element used to monitor changes to the
browser's font size so that:
- Safari's status bar no longer displays a "Loading..." message after the
page has loaded.
- Firefox no longer reports duplicate cookie information.
- The browser scrollbars no longer flash on and off in Firefox.
+ It is now possible to set the "button" configuration property of a
YAHOO.widget.Dialog instance after it has be rendered.
+ Form elements appended to a YAHOO.widget.Dialog instance via the "setBody"
method are now automatically registered using the "registerForm" method.
+ The "focusFirst" method of YAHOO.widget.Dialog will no longer result in a
JavaScript error in IE if the first element in the Dialog instance's form
is a radio button.
+ YAHOO.widget.Panel instances whose "draggable" property is set to "true" and
"width" property is set to "auto" are now able to be dragged in IE 6 (Quirks
and Strict Mode) and IE 7 Quirks Mode.
+ Updated focus methods of YAHOO.widget.Dialog to prevent JavaScript errors
that result from trying to set focus to elements that hidden or disabled.
+ Pressing the enter key will no longer result in a YAHOO.widget.Dialog
instance's "validate" method being called twice.
+ Pressing the enter key while focused on a form field inside a Dialog will no
longer trigger the "click" event handler defined by the Dialog's default
button in IE and Firefox.
+ Pressing the enter key when focused on a form field inside a
YAHOO.widget.Dialog instance with no buttons created via its "buttons"
configuration property will no longer result in a JavaScript error.
+ Aqua scrollbars will no longer bleed through Container widgets in Firefox
for Mac OS X.
+ The "width" and "height" configuration properties of YAHOO.widget.Overlay
now supersede the "fixedcenter" and "context" configuration properties to
ensure correct positioning of Overlay instances using the "fixedcenter"
and "context" configuration properties.
+ Calling the "destroy" method on a YAHOO.widget.Overlay instance no longer
results in a JavaScript error on the subsequent focus of another
Overlay instance.
+ YAHOO.widget.Tooltip instances without a value specified for the "width"
configuration property will be rendered at a width equal to the offsetWidth
of their root <DIV/> element to prevent their width from being clipped or
constrained by their parent HTML element.
Changes:
--------
+ Rendering of YAHOO.widget.Tooltip instances is now deferred using the
"onDOMReady" event handler of YAHOO.util.Event rather than waiting until
the "load" event of the Tooltip's parent window fires.
+ Deprecated "browser" property of YAHOO.widget.Module in favor
+ The "moveEvent" of a YAHOO.widget.Panel instance now also fires with the
"endDrag" event of the its YAHOO.util.DD instance.
+ Updated modal functionality of YAHOO.widget.Panel:
- The creation of a Panel instance's modality mask is now deferred until it
is initially made visible.
- Showing a modal Panel instance will now result in the Panel and its
associated modality mask element having a higher z-index than all other
YAHOO.widget.Overlay instances and Overlay subclasses.
+ Updated the "underlay" configuration property of YAHOO.widget.Panel:
- The creation of the underlay element is deferred until the Panel
instance is initially made visible.
- For Gecko-based browsers on Mac OS X the underlay elment is always
created as it is used as a shim to prevent Aqua scrollbars below a Panel
instance from poking through it.
- For IE 7 (Quirks Mode) and IE 6 (Quirks Mode and Standard Mode) the
underlay element is resized in response to a change to a Panel instance's
"width" or "height" configuration properties, a change to the browser's
font size or the firing of the contentChangedEvent (triggered by use of
the "setHeader," "appendToHeader," "setBody," "appendToBody,"
"setFooter," or "appendToFooter" methods).
+ Updated the "iframe" configuration property of YAHOO.widget.Overlay:
- The creation of the <iframe> shim element is deferred until the Overlay
instance is initially made visible.
- The <iframe> shim element is resized when a change to an Overlay
instance's content is made at runtime via the "setHeader,"
"appendToHeader," "setBody," "appendToBody," "setFooter," or
"appendToFooter" methods.
+ Updated the "buttons" configuration property of YAHOO.widget.Dialog:
- YAHOO.widget.Button is now an optional dependancy, and if included, each
button in a Dialog will be an instance of Button.
- The "text" property of each button now accepts HTML
- The "handler" property of each button can now be set to:
+ A reference to a function that should fire when the button is
clicked. (In this case scope of this function is always its
Dialog instance.)
+ An object literal representing the code to be executed when the
button is clicked. The format is:
{
fn: Function (The handler to call when the event fires.),
obj: Object (An object to pass back to the handler.),
scope: Object (The object to use for the scope of the handler.)
}
Added the following features:
-----------------------------
+ Added ability for YAHOO.widget.Tooltip instances to have shadow:
- The shadow for a Tooltip is implemented by appending a new element as the
last child of its root <DIV/> element:
<DIV class="yui-tt">
<DIV class="bd"> ... </DIV>
<DIV class="yui-tt-shadow"/>
</DIV>
- The code that creates the shadow element resides inside the Tooltip's
public "onRender" prototype method. To disable the creation of a
Tooltip's shadow override the prototype of the "onRender" method:
YAHOO.widget.Tooltip.prototype.onRender = function () {};
- The actual creation of the shadow element is deferred until the Tooltip
is made visible for the first time.
- A Tooltip's shadow element can be styled via two CSS classes:
+ "yui-tt-shadow" - Applied to the shadow element when it is created.
+ "yui-tt-shadow-visible" - Applied to the shadow element when the
Tooltip is visible; it is removed the Tooltip is hidden.
- The shadow element is only styled when using the new "Sam" skin, for
the previous default skin its "display" property is set to "none."
+ Prototype of all classes (Module, Overlay, Panel, Dialog, SimpleDialog,
Tooltip, Config, and ContainerEffect) are augmented with
YAHOO.util.EventProvider, facilitating subscribing to an instance's
Custom Events by name via a "subscribe" method that is a direct member of
the class. For example:
var oOverlay = new YAHOO.widget.Overlay("myoverlay");
oOverlay.subscribe("show", onShow);
+ Added a new "bringToTop" method to YAHOO.widget.Overlay that places the
Overlay on top of all other Overlay instances.
+ Added a new "bringToTop" method to YAHOO.widget.OverlayManager that places
the specified Overlay instance on top of all other Overlay instances. This
method is called on each Overlay instance that is registered with an
OverlayManager instance.
+ Dialog instances are now able to upload files should the Dialog instance's
form contain <input type="file"/> elements. PLEASE NOTE: If a Dialog
instance will be handling asyncronous file uploads, its "callback" property
will need to be setup with an "upload" handler rather than the standard
"success" and, or "failure" handlers. For more information, see the
Connection Manager documenation on file uploads:
+ Added a new "getButtons" method to YAHOO.widget.Dialog that returns an array
containing each of the Dialog's buttons; by default an array of HTML <BUTTON>
elements. If the Dialog's buttons were created using the
YAHOO.widget.Button class (via the inclusion of the optional Button
dependancy on the page), an array of YAHOO.widget.Button instances
is returned.
+ Added a "destroy" method to YAHOO.util.Config that sets all properties to
null, unsubscribes all listeners from each property's change event and all
listeners from the configChangedEvent. The "destroy" method of
YAHOO.widget.Module now automatically calls the "destroy" method of its
configuation object.
+ Added a "IFRAME_OFFSET" constant to YAHOO.widget.Overlay that controls how
much the <iframe> shim should be offset from each side of an
Overlay instance.
+ Added a new "syncIframe" method to YAHOO.widget.Overlay that syncronizes the
size and position of the <iframe> shim to that of the Overlay.
+ Added a "ICON_CSS_CLASSNAME" constant to YAHOO.widget.SimpleDialog that
represents the name of the CSS class applied to the element created by the
"icon" configuration property.
Known Issues
------------
+ "Sam" skin Panel missing left and right borders when declared with a height
---------------------------------------------------------------------------
If the height of a Panel instance exceeds the total height of its header,
body and footer elements, the space not filled with content will lack a left
and right border. Therefore, to set a Panel instance to a fixed height
when using the "Sam" skin, apply the desired height to the body element,
taking into account the height of the header and footer elements. To set the
height of a Panel instance's body via CSS:
#mypanel .bd {
height: 100px;
}
Or via JavaScript:
oMyPanel.body.style.height = "100px";
+ Elements with scrollbars poke through Overlay instances floating above them
---------------------------------------------------------------------------
There is a bug in Gecko-based browsers for Mac OS X where an element's
scrollbars will poke through absolutely positioned elements floating above
them. To fix this problem the "overflow" property of an Overlay instance's
root element is toggled between "hidden" and "auto" (through the application
and removal of the "hide-scrollbars" and "show-scrollbars" CSS classes) as its
"visibility" configuration property is toggled between "false" and "true."
PLEASE NOTE:
1) The "hide-scrollbars" and "show-scrollbars" CSS classes classes are
applied only for Gecko on Mac OS X and are added/removed to/from the
Overlay's root HTML element (DIV) via the "hideMacGeckoScrollbars" and
"showMacGeckoScrollbars" methods of YAHOO.widget.Overlay.
2) For Panel (and its subclasses) it is the underlay element, not the root
element, whose "overflow" property is toggled between "hidden" and "auto."
The underlay element therefore acts as a shim to correct the
scrollbar problem.
3) For Tooltip instances using the "Sam" skin it is the shadow element, not
the root element, whose "overflow" property is toggled between "hidden"
and "auto." The shadow element therefore acts as a shim to correct the
scrollbar problem.
4) Once the fix is applied the bug will reappear if the window loses focus.
This can be remedied via Javascript by hiding and showing the Overlay
instance when the window receives focus:
YAHOO.util.Event.on(window, "focus", function () {
});
** For more information see
+ Scrollbars remain visible after an Overlay is hidden
----------------------------------------------------
There is a bug in Gecko-based browsers for Mac OS X where an element's
scrollbars and the scrollbars of its child nodes remain visible when its
"visibility" property property is set to "hidden." To fix this problem,
the "overflow" property of an Overlay instance's root element and child nodes
is toggled between "hidden" and "auto" (through the application and removal
of the "hide-scrollbars" and "show-scrollbars" CSS classes) as its
"visibility" configuration property is toggled between "false" and "true."
PLEASE NOTE:
1) The "hide-scrollbars" and "show-scrollbars" CSS classes classes are
applied only for Gecko on Mac OS X and are added/removed to/from the
Overlay's root HTML element (DIV) via the "hideMacGeckoScrollbars" and
"showMacGeckoScrollbars" methods of YAHOO.widget.Overlay.
2) There may be instances where the CSS for a web page or application
contains style rules whose specificity override the rules implemented by
the Container CSS files to fix this bug. In such cases, is necessary to
leverage the provided "hide-scrollbars" and "show-scrollbars" classes to
write custom style rules to guard against this bug. For example:
To fix the scrollbars issue for an Overlay instance with an id of
"myoverlay" whose body element has scrollbars applied by default:
#myoverlay .bd {
height: 100px;
/* Apply scrollbars for all browsers. */
overflow: auto;
}
#myoverlay.hide-scrollbars .bd {
/* Hide scrollbars by default for Gecko on OS X */
overflow: hidden;
}
#myoverlay.show-scrollbars .bd {
/* Show scrollbars for Gecko on OS X when the Overlay is visible */
overflow: auto;
}
To fix the scrollbars issue for a Panel instance with an id of "mypanel"
whose body element has scrollbars applied by default:
#mypanel .bd {
height: 100px;
/* Apply scrollbars for all browsers. */
overflow: auto;
}
.yui-panel-container.hide-scrollbars #mypanel .bd {
/* Hide scrollbars by default for Gecko on OS X */
overflow: hidden;
}
.yui-panel-container.show-scrollbars #mypanel .bd {
/* Show scrollbars for Gecko on OS X when the Panel is visible */
overflow: auto;
}
** For more information see
+ Flash Movies appear on top of Overlay instances
-----------------------------------------------
Flash movies can appear on top of Overlay instances in IE and Gecko-based
browsers. To fix this problem, set the "wmode" of the Flash movie to either
"transparent" or "opaque" as indicated below:
Via the <object> tag:
<object>
<param name="wmode" value="opaque">
</object>
<object>
<param name="wmode" value="transparent">
</object>
Via the <embed> tag:
<embed wmode="transparent"> ... </embed>
<embed wmode="opaque"> ... </embed>
** For more information see
+ Overlay instances not rendered at correct z-index in IE
-------------------------------------------------------
In IE, when an Overlay instance is rendered inside a relatively positioned
element the z-index of the Overlay instance is now relative to its
relatively positioned parent element. This is not a bug in the
Overlay class, but rather a bug in IE where relatively positioned elements
establish a new stacking context for their child nodes. To avoid this
bug it is recommend that all Overlay instances that need to be able to float
above any other element in the document be made direct descendants of the
<body> element.
** For more information see
+ Header elements for Panel instances using "Sam" skin shrinkwrap in IE 7
-----------------------------------------------------------------------
In IE 7 (Standards Mode) if a Panel instance is created without specifying a
value for the "width" configuration property the width of the Panel's
header element will shrinkwrap to the width of its text node. To avoid
triggering this bug in IE always specify a value for the "width"
configuration property when using Panel.
+ Panel instances render at 100% of the browser viewport
------------------------------------------------------
In IE 7 (Quirks Mode) and IE 6 (Quirks Mode and Standards Mode) if any of the
child nodes of a Panel instance's root element have "layout"
(http://msdn2.microsoft.com/en-us/library/ms533776.aspx) and no value
has been specified for the "width" configuration property, the Panel will
render at 100% of the width of browser's viewport. This bug will manifest
when using the "Sam" skin as layout is applied to the header, body and
footer elements (by setting the CSS "zoom" property of the element to "1" )
in order to get the negative margins required for the rounded corners to
render correctly. To avoid triggering this bug in IE always specify a value
for the "width" configuration property when using Panel.
+ Panel instances render at 2px wider when using "Sam" skin
---------------------------------------------------------
For the "Sam" skin a Panel instance's rounded corners are created via the
application of negative 1px left and right margins on the header, body and
footer elements. These negative margins will cause a Panel instance to be
rendered at 2px wider than the value specified by the "width" configuration
property. Therefore, when using the "Sam" skin consider the negative left
and right margins and subtract 2 from the value passed to the "width"
configuration property in order to have the Panel render at the desired
width. For example, to render a Panel 300px wide, pass a value of "298px"
to the "width" configuration property.
*** version 2.2.2 ***
+ Clicking the close button of a Panel (or any instance of a Panel subclass)
registered with an OverlayManager will no longer result in the Panel
receiving focus.
+ Overlay instances registered with an OverlayManager will now correctly
blur themselves when hidden.
+ Calling the "destroy" method of an Overlay instance will now result in it
being removed from its OverlayManager instance(s).
+ The DOM event listener for the event defined by the "focusevent"
configuration property of an OverlayManager instance is now removed from each
Overlay instance when it is removed from its OverlayManager.
+ All subscribers for an Overlay instance's "focus" and "blur" events are
now unsubscribed when it is removed from its OverlayManager.
*** version 2.2.1 ***
+ Made the default scope for all Custom Events published by Module, Overlay,
Panel, Tooltip, Dialog and SimpleDialog the widget instance. Previously the
default scope for Custom Events was inconsistent across classes; the default
scope for Custom Events published by Overlay was always the Overlay instance
whereas the Custom Events published by all of the other classes had no
default scope.
+ Added default scope for CustomEvents published by YAHOO.util.Config:
- Default scope for the "configChangedEvent" is now the Config instance.
- Default scope for Config property events is now the Config's owner (widget).
+ Panel and Tooltip now always convert the value of a DOM element's "tagName"
property to uppercase before evaluating it. This improves
XHTML compatibility.
+ Pressing the enter key while focused on a form field inside a Dialog will
now trigger the "click" event handler defined by the Dialog's default
button in IE and Firefox. Previously, this behavior only worked in Safari
and Opera.
+ Added a "yui" prefix to the default CSS class name for Module to be
consistent with the other Container family widgets.
+ Container/Panel's underlay shadow is now defined as partially-transparent
black rather than gray. This prevents the shadow from lightening the
background color of elements beneath it.
+ Fixed memory leaks in Panel and Dialog.
+ The Drag and Drop library is now a truly optional dependency for Panel and its
subclasses.
+ Panel "focus" and "blur" events are now fired when Panels are focused and
blurred via the "focus" and "blurAll" methods of YAHOO.widget.OverlayManager.
+ Panel instances rendered without setting the value for the "width"
configuration property will now have their "width" configuration
property set to the value of the Panel's element's "offsetWidth" property
when rendered. This fixes an issue in IE 6 and 7 where Panels that are
rendered without setting the "width" configuration property will only be
draggable by mousing down on the text inside the header, rather than anywhere
inside the header.
+ Refactored the Container family including the Config class to improve
performance, especially when working with a large number of instances in IE6.
