推荐答案
在 Flex 中设置选项卡样式有点棘手 - TabBar 和 TabNavigator 类有一个名为 tabStyleName
的样式,这是另一个的名称定义选项卡外观的单独样式.这是一个示例,它通过更改 TabBar 上的 tabStyleName
样式将一组选项卡从红色背景更改为蓝色 - 希望您可以根据需要进行调整.
Styling tabs in Flex is sort of tricky - the TabBar and TabNavigator classes have a style called tabStyleName
, which is the name of another separate style that defines the look of your tabs. Here's an example which changes a set of tabs from a red background to blue by changing the tabStyleName
style on the TabBar - hopefully you can adapt it to whatever you need.
<mx:Style>
.redTabs {
fillColors: #cc0000, #cc0000;
}
.blueTabs {
fillColors: #0000cc, #0000cc;
}
</mx:Style>
<mx:Script>
<![CDATA[
protected function changeStyle(event:MouseEvent):void
{
theTabs.setStyle("tabStyleName", "blueTabs");
}
]]>
</mx:Script>
<mx:TabNavigator id="theTabs" x="10" y="10" width="200" height="200" tabStyleName="redTabs">
<mx:Canvas label="apple" width="100%" height="100%">
</mx:Canvas>
<mx:Canvas label="orange" width="100%" height="100%">
</mx:Canvas>
<mx:Canvas label="banana" width="100%" height="100%">
</mx:Canvas>
</mx:TabNavigator>
<mx:Button x="10" y="218" label="Change Style!" click="changeStyle(event)"/>
我已更改示例以使用 TabNavigator.
I've changed the example to work with TabNavigator.
