I copy and paste the spark.skins.spark.PanelSkin to create a custom Panel with
a close button.There are two problem. I defined some style in the CusPanel.mxml
which inherit the Panel. How can let the button in the skin class access these
properties? The second problem is when I clicked the button cause a error
alert. Is there any new component in Flex4 like TitleWindow in flex3 ?
CusPanel.mxml
<s:Panel ...>
<fx:Metadata>
[Style(name="gridentColor",type="Array",inherit="yes",arrayType="int")]
[Style(name="close-button-over-background-color", type="uint", inherit="yes",
format="Color")]
[Style(name="close-button-down-background-color", type="uint", inherit="yes",
format="Color")]
[Style(name="close-button-down-background-solid-color", type="uint",
inherit="yes", format="Color")]
</fx:Metadata>
</s:Panel>
CusPanel.mxml
<!-- copy from the PanelSkin.mxml -->
<s:Group id="topGroup" mask="{topGroupMask}">
...
...
<s:Button skinClass="CloseButtonSkin" right="3" verticalCenter="0" width="15"
height="15"/>
</s:Group>
