Flex Examples
The following example shows how you can change the appearance of the close button in a TitleWindow container in Flex by setting the closeButtonSkin style (or the closeButtonUpSkin, closeButtonOverSkin, closeButtonDownSkin, closeButtonDisabledSkin styles individually).
Full code after the jump.

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical"
verticalAlign="middle"
backgroundColor="white">
<mx:Style>
TitleWindow {
closeButtonSkin: Embed("cancel.png");
/* Set values from defaults.css to null. */
closeButtonDisabledSkin: ClassReference(null);
closeButtonDownSkin: ClassReference(null);
closeButtonOverSkin: ClassReference(null);
closeButtonUpSkin: ClassReference(null);
}
</mx:Style>
<mx:TitleWindow id="titleWindow"
title="TitleWindow"
status="status message"
showCloseButton="true"
width="100%"
height="100%" />
</mx:Application>
View source is enabled in the following example.
If you want to use a different image for each state (up, over, down, disabled), you can either set each skin separately, as seen in the following snippet:
<mx:Style>
TitleWindow {
closeButtonUpSkin: Embed("bullet_green.png");
closeButtonOverSkin: Embed("bullet_yellow.png");
closeButtonDownSkin: Embed("bullet_red.png");
closeButtonDisabledSkin: Embed("bullet_white.png");
}
</mx:Style>
Or, you can specify a SWF file and symbol name for the close button skins, as seen in the following snippet:
TitleWindow {
closeButtonDisabledSkin: Embed(source="Assets.swf", symbol="CloseButtonDisabled");
closeButtonDownSkin: Embed(source="Assets.swf", symbol="CloseButtonDown");
closeButtonOverSkin: Embed(source="Assets.swf", symbol="CloseButtonOver");
closeButtonUpSkin: Embed(source="Assets.swf", symbol="CloseButtonUp");
}
Or, you can create a Flex Componet skin using the Flex Component Kit and Flash CS3 where the movie clip symbol in the library has the following frame labels: up, over, down, disabled, as seen in the following example:
<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2007/12/31/changing-the-close-button-skin-on-a-flex-titlewindow-container/ -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical"
verticalAlign="middle"
backgroundColor="white">
<mx:Style>
TitleWindow {
closeButtonSkin: Embed(skinClass="BulletSkins");
/* Set values from defaults.css to null. */
closeButtonDisabledSkin: ClassReference(null);
closeButtonDownSkin: ClassReference(null);
closeButtonOverSkin: ClassReference(null);
closeButtonUpSkin: ClassReference(null);
}
</mx:Style>
<mx:TitleWindow id="titleWindow"
title="TitleWindow"
status="status message"
showCloseButton="true"
width="100%"
height="100%" />
</mx:Application>

Interesting .. but need further help.
This is a very helpful blog. Thank you very much for sharing it.
This is the first time that I have to deal with skin class and I do not completely following your example. So here is what I am doing.
I am using flex 2. My file structure is
src
app.mxml
com
myapp
components
myPopup.mxml
css
app.css
images
cancel.png
The cancel.png is exactly following your example
So here is the issue, when I added the styles into my css, whatever I did, the new cancel button did not show up.
I actually copied cancel.png to all the possible locations and it still would not work. I am using Flex Builder 2 right now. Could you please let me know what I did wrong? Thank you again
Melvin,
Does the following work in your app.css?
/* CSS file */ TitleWindow { closeButtonSkin: Embed("../images/cancel.png"); /* Set values from defaults.css to null. */ closeButtonDisabledSkin: ClassReference(null); closeButtonDownSkin: ClassReference(null); closeButtonOverSkin: ClassReference(null); closeButtonUpSkin: ClassReference(null); }Peter
Because in Module not appear a image in CLose Button ?
Hi Peter,
Great stuff as usual.
Im curious if you might consider doing a blog entry on how to add additional ‘buttons’ to the titlewindow header. Is this possible?
Hi Peter,
This solution works but it stretches my close button, do you have any idea?
Thanks
Guy
Ok, I see now that the image should be 16*16 mine was 11*11.
Is this stuff documented anywhere?
@guy,
I don’t know. If it isn’t in the documentation (http://livedocs.adobe.com/flex/3/langref/), it may be documented in some code somewhere. You could file a bug at http://bugs.adobe.com/flex/ and somebody could take a look. You may be able to work around it by using a scale-grid or something (or just resizing your icon to 16×16).

Hi, my close button is having size 10*10 and it becomes stretchy. What I do is to resize the image to 16*16 and the problem solved.
I find the cross is just a little small – don’t you? I went to enlarge it but unfortunately it’s been exported by a drawing tool. If someone can give me the codes that I need to stick in to replace the three lines that look like: data=”M 3 5 L 4 5 L 4 6 L 5 6 L 5 7 L 4 7 L 4 8 L 3 8 L 3 9 L 4 9 L 4 10 L 5 10 L 5 9 L 6 9 L 6 8 L 7 8 L 7 9 L 8 9 L 8 10 L 9 10 L 9 9 L 10 9 L 10 8 L 9 8 L 9 7 L 8 7 L 8 6 L 9 6 L 9 5 L 10 5 L 10 4 L 9 4 L 9 3 L 8 3 L 8 4 L 7 4 L 7 5 L 6 5 L 6 4 L 5 4 L 5 3 L 4 3 L 4 4 L 3 4 L 3 5 Z” in order to make it larger then I would be extremely grateful. I know how to do the rest (reposition it and enlarge the box).
