Fade Effect Query

I am looking for assistance with the spry fade effect. i have
a number of divs all with the same class currently being output via
coldfusion on the page.
the plan is that when i mouse over one div, all the other
divs with the same class fade down slightly so the focused div
stands out. the class for the divs is called "box1" for example and
there are 15-17 "boxes" per page. Im fairly sure i have seen this
effect somewhere just cant seem to find it.
can anyone help out with this or point me in the direction of
someone you can? i appreciate spry may not be the best way to
tackle this so any suggestions or advice relating to other libaries
would be great too. (currently using jquery elsewhere in the site)
any assistance will be greatly appreciated,
Cheers, Sean

I'm guessing those boxes are the only one with that
className.
So the best and ideal solution would be to include
SpryDOMUtils.js (is included in the labs download package folder
"includes")
Add it to your page.
And do a little change to that File. We are going to extent
the base funtionality of the results so we can apply fade to each
of those elements.
At the bottom of your SpryDOMUtils.js add this:
Spry.$$.Results.fade = function(from,to)
return this.forEach(function(n) {
Spry.Effect.DoFade(n,{from:from, to:
to});});
Now you can do in your js
Spry.$$('.box1').fade(100,60);
And it should fade all boxes with the classname .box1 to 60%
O wait. you wanted it on mouse over.. Still include the
SpryDOMUtils.js
but now do:
Spry.$$('.box1').addEventListener('mouseover',function(){Spry.Effect.DoFade(this,{from:100 ,
to:
60});})

X6 menu fade effect query

Im wondering if theres anything to disable this...or its just me...i turned off the theme effects already. I just dont like it, i feel like it slows down the fone...im wondering if there could be any future updates on the nokia X6 since the last one was v40? Nokia need to remove this menu fade effect! seriously...

It is not possible to removed it as it is part of the default theme shell.
If you find this post helpful, a click upon the white star at bottom would always be appreciated.
If it also solves your problem, clicking ACCEPT AS SOLUTION below it will benefit other users!

Tabbed Panel with Fade Effect

Open my site, dg-ad.com, and the tabbed panel drop down menu has the first level visible. Click on a menu item and the second level becomes visible. The second level has a Spry fade effect so it fades into view nicely. The class .TabbedPanelContent sets the visibilty of the second layer hidden, and there is no distracting flicker, good so far.
Besides clicking on menu item I often send clients a link with a string query which lands them on my site with the tabbed panel open to what I want them to see initially., I use a string query in the URL per Dave Powers technique often refered to in this forum titled'Spry: Opening Specific Tabs and Panels from Another Page".
Because the visibility is set to hidden in the CSS the second level of the tabbed panel is still invisible, So I am looking for suggestions that may involve scripting the style or playing with the CSS to overide the CSS and make the second level visible when users arrive via the query string method.
Thanks for taking a look!

For Spry 1.0 widgets, each widget had one core file. Each of them had common things like addClassName(), removeClassname(), along with a bunch of basic functionality. So that adds up to a lot of redundant code.
This way, all that common stuff is kept in a single file. That means that each widget base class just has what it needs to glue everything together.
Many widgets are 'panel' based: accordions, tabbed panels, slideshows. So handling those panels is done via the PanelSet and PanelSelector files.
You will find SpryTabbedPanels2.js much smaller than the first version.
By components, for instance: SpryFadingPanels.js is only needed if you want to fade between panels. If you don't want that effect, you don't need to use it. WIth components and plugins, you or anyone else can write a different transition and make that available to all your Spry UI widgets.
I don't like all the includes either but it's the right way to go with what we are doing.
Thanks,
Don

Image rotation with fade effect

I am new to the spry framework and have just started going
through the examples to see if I could create an image rotator that
fades the images into each other when changing. I have taken
snippets from different places to do this and think I have the
answer but really wanted some feedback to sanity check and let me
know if this is the best way of doing it. If it is, then I hope
others will find it useful.
Here is the url to the example:

Fade effect question

I can implement a fade in effect with a single image, but I
cannot get the same code to work with the arrayed images generated
in the "photoDemo" tutorial on the Adobe site. Sho Kuwamoto has a
fade in working in his tutorial (
http://labs.adobe.com/technologies/flexbuilder2/tutorials/#)
though with different syntax (that I can't make work either), so I
know the array isn't the issue. Why does this work in one, but not
the other, example?
Any help would be greatly appreciated. I'm using the FB3
Beta for the moment.
Thanks in advance.
1) In this example, the fade out works fine ...
<?xml version="1.0"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Fade id="fadeOut" duration="1000" alphaFrom="1.0"
alphaTo="0.0"/>
<mx:Fade id="fadeIn" duration="1000" alphaFrom="0.0"
alphaTo="1.0"/>
<mx:Panel title="Fade Effect Example" width="95%"
height="95%"
paddingTop="5" paddingLeft="10" paddingRight="10"
paddingBottom="5">
<mx:Text width="100%" color="blue"
text="Use the Fade effect to show or hide the text and
image. Use an embedded font when applying the Fade effect to
text."/>
<mx:Image source="photo.png"
visible="{cb1.selected}"
hideEffect="{fadeOut}" showEffect="{fadeIn}"/>
<mx:CheckBox id="cb1" label="visible"
selected="true"/>
</mx:Panel>
</mx:Application>
2) In the itemRenderer ("thumbnails" here) of the "photoDemo"
tutorial on the Adobe site (
http://learn.adobe.com/wiki/display/Flex/1b.+Code+Files),
it does not. It compiles and runs, but seems to ignore the effect
call. Why?
"thumbnails" ...

paddingTop="5">
<mx:Fade id="fadeIn" duration="1000" alphaFrom="0.0"
alphaTo="1.0"/>
<mx:Image source="{data.thumbnail.url}"
showEffect="{fadeIn}" />
</mx:VBox>
main ...

I've never used this effect. Maybe if you preload the image(s)...
Go to Behaviors panel.
Click the plus sign (+).
From the drop menu, select Preload Images.

Fade Effect working weird.

My little app is driven by a TabNavigator with each tab
showing a different "page" with DataGrids/Form/TabNavs etc. I am
trying to fade from "page" to "page" and all looks fine except Text
types on the "page". They don't fade, just abruptly disappear once
the fadeOut alpha reaches some number. Am I missing something? All
help is appreciated.

first be embedded.
Or, if you can get direct access to the text objects, you can
set the
blendMode of the text to "layer", and then Fade effects will
work on them
properly.

Fade Effect

I have a code on my buttons, which makes a blank image
currently on stage get replaced with a different one when a button
is rolled over.
The code I am using is this:
on mouseenter me
sprite(3).member="a"
on mouseleave me
sprite(3).member="blank"
end
Very simple lingo. Is there a way that when the new image
comes to view, it fades in when the mouse rolls over the button,
instead of just popping in, and fade out once the mouse leaves the
button, so that I end up with a smooth transition.
Thank you.

Guys:
Thanks for taking your time to help me with the issue.
I actually got an answer from another member that solved my
problem. The code that was posted here was making the button sprite
do the fade effect.
My friend did some tweaking to that code to achieve what I
needed.
Here is the code:
property fadeSprite
property totalSteps
property eachStep
property animateMe
on getPropertyDescriptionList
myPropList = [:]
myPropList.addProp(#totalSteps,[#comment:"select the number
of steps for the
fade:",#format:#integer,#range:[#min:5,#max:20],#default:10])
myPropList.addProp(#fadeSprite,[#comment:"enter the sprite
to fade:",#format:#integer,#default:1])
return myPropList
end
on beginSprite me
sprite(fadeSprite).blend = 0
animateMe = true
eachStep = 100/totalSteps
end
on mouseEnter me
animateMe = false
end
on mouseLeave me
animateMe = true
end
on enterFrame me
if animateMe then
if sprite(fadeSprite).blend > 0 then
sprite(fadeSprite).blend = sprite(fadeSprite).blend -
eachStep
end if
else
if sprite(fadeSprite).blend < 100 then
sprite(fadeSprite).blend = sprite(fadeSprite).blend +
eachStep
end if
end if
end
With this one, I am able to select which sprite is fading in
and out. Again, thanks for your help.

Fade Effect problem in IE

hi everyone,
I'm having problems with a fade out/in transition in IE8. The area I am changing has a white background (actually there are a few nested divs that all have a white background), and the fade effect triggers on a click in the navigation area and fades everything into the body background color (dark brown) and back. The effect works fine in firefox and safari. Anyone know how to fix this problem? I want the content that is fading to maintain the white background and not fade to brown and back. you can view the page here to see whats going on.
http://www.prometheusbusiness.com/testarea/NoelRose/home.html
also, (and this is a really small issue, so I'm not too concerned if I can't fix it) after the page loads, the first fade out transition doesnt seem to fire, it just disappears, and the new page fades in. after the first time, everything works as I expect, but it would be great if every click worked exactly the same every time.
any help is appreciated, thanks.

Fade effect bold text in all IEs

I have created the following page
Cnet about
and used the spry fade effect on the section of text at the bottom
below the "A Sampling of what we offer" graphic.
It works fine but in IE6 and IE7 when viewed on an LCD
monitor, the bold blue text looks very choppy. I assume this has to
do with bad handling of opacity in IE. Does anyone know a hack to
fix this?

Hi artdoggy,
That is an IE bug with several workarounds. The first
workaround which is much simpler, is to specify a background color
or font on the element that you are fading in. This somehow
triggers IE to avoid this behavior.
The other workaround is to use an effect onPostEffect
observer or finish function to unset the filter function on the
element. You can see sample of how to use an observer here:
http://labs.adobe.com/technologies/spry/samples/effects/observers_sample.html
You'll have to do something like this in your observer:
effect.element.style.filter = "";

Fade effect after inactivity in ADF 11.1.1.6 application

Hello everyone,
after a period of inactivity (about 10-15 minutes) in my ADF application (v. 11.1.1.6) the page is shown in semi-transparency mode with a little icon of warning on the bottom of the page. This fade effect disappears after a mouse move.
How can we disable this behaviour?
Please note that this effect is related only on the af:table component.
Thanks in advance,
Baduel

Here the testcase: https://dl.dropboxusercontent.com/u/3932597/TestFade.rar
After some test I notice that this kind of issue happens if there is an af:poll in the page. Is it possible that is raleted to the new property (timeout)? http://jdevadf.oracle.com/adf-richclient-demo/docs/tagdoc/af_poll.html
For the test case. Use HR schema, run index.jspx and click on Section tab (or also Section box). Wait about 15 minutes (with no page interaction) and the glass pane will appear with the warning icon on the bottom of the page.
Thanks everyone.

Fade Effect transparency IE/Firefox

Hi,
I am using the Spry:Fade effect with the image to be faded
constructed in Fireworks. The image has a transparent background
and a rectangle with a feathered edge effect.
The fade works well using Firefox however in Internet
Explorer a substantial part of the feathered edge effect turns
black. This occurs whether the image is either a gif or a png
format.
Any suggestions on what causes this and a fix/workaround.
Thanks,

Fade effect: how to do with "onEnterFrame"?

Hi,
I have a map with each city represented as a dot (MC). When
you mouse over the dot, another MC with more city details/text
quickly fades in, and fades out when you roll out. But I can't get
the full fade effect working. Need your advice...
In the dot MC, I put:
on (rollOver) {
_root.showCity();
on (rollOut) {
_root.hideCity();
In the root, showCity() and hideCity() are functions to fade
in and out the city details MC (city_sanfrancisco). I figured they
should be at the root level so they can be used by other city dots
(city_sandiego, city_boston, etc.) as well:
//this lets me change the speed for fading in and another
speed for fading out
var speedIn;
speedIn = 20;
var speedOut;
speedOut = 20;
//hard-coded city for now; set city to invisible when movie

var city = city_sanfrancisco;
city._alpha = 0;
//this shows the city details by fading in
function showCity(){
city._alpha += _root.speedIn;
if (city._alpha > 100){
city._alpha = 100;
function hideCity(){
city._alpha -= _root.speedOut;
if (city._alpha < 0){
city._alpha = 0;
What this doesn't do is the full fade effect, because the
function only executes once, so city._alpha doesn't reach 100 when
it fades in. I've seen in other fade effect scripts, that they use
the enterFrame event, but I don't now how to use it here... or what
is the right syntax to make the city details MC fade in to 100% on
rollOver, and fade out to 0 on rollOut... and still be able to
apply a speed setting.
Any help would be appreciated.

you could try something like this:
on(rollOver){
onEnterFrame = showCity;
then modify your showCity function slightly:
function showCity(){
city._alpha += _root.speedIn;
if (city._alpha > 100){
city._alpha = 100;
delete onEnterFrame;
.. with similar adjustments to you on rollOut code.
Hope this helps,
Sinead.

Fade Effect Issue with table structure

I have an existing HTML page with a table framework that uses
CSS divs in some of the table rows. My SPRY data is currently
wrapped in DIV tags within the table. I've discovered that the
table is screwing up the fade effect in IE7. Is there any way I can
get around this without removing the table and recoding the whole
page in CSS? FYI...I using version 1.4. I'm not sure if 1.5 will
fix this issue.

Essentially the fade in fade out effect isn't working at all
in IE. It's setup as a slideshow and uses the fade effect as a
transition between the spry data. The slideshow works fine just
without the fade effect. Everything works perfectly in Firefox
though. I know this code will work as we have used it before, the
only thing different is that I have my DIV with the SPRY content
wrapped within a table cell and row. I've read that the TR tag
cannot be used, but it's not exactly using the TR as an ID. Once I
comment out the table, tr, and td tags, the effect works no problem
so I know it is the table. I can't give you the URL because it's on
our local network.

Fade effect with DataGrid. Header text are visible ... :(

Hi,
the problem with DataGrid.
If I specify the Fade effect for showing DataGrid, all lines
are showing correct, so the fade works, but the headers text and
the data texts are showing immediately (like without Fade).
Is it possible to avoid this effect? I want to show my
datagrid from alpha 0.00 to 1.00 for ALL elements (for lines, for
headers, for headers TEXT and of course of data TEXT)
Is it a bug?

I had the same problem. I havent fixed it but I did a work
around and used a WipeDown effect in parallel. It eliminates the
headers of appearing immediately.

Firefox is hanging when the page scrolls down to a html5 video or the page to a slideshow with fade effect

Every time a page has a html5 video or a slideshow with fade effect Firefox 3.6 becomes terriblely slow. It freezes with this test: http://demos.hacks.mozilla.org/openweb/HWACCEL/
I have Fedora 14 and before that Fedora 13 and the problem happens with both.
The same doesn't happen on Opera or Google Chrome.
'''UPDATE 1''': I have already tryed the Safe Mode and the problem happens the same.
'''UPDATE 2:''' This page full of videos scroll smothly without any problemas: http://brettgaylor.tumblr.com/tagged/webmademovies

I forgot to say that I did tryed the Safe Mode just to see if the slow was not being caused by some extension or plugin. However the result was all the same. By the way, the slow happens even if there is only one page opened. I am not thinking it is something related to the ATI video card or even Fedora because the same slow does't happen in Chrome and Opera...
