Corner radius applied only to specific corners

I've this tabs that I wanted to make rounded only on top-right and top-left corners. But it ended up rounding all 4 corners.

What I did:

<mx:TabNavigator id="myTabNav" x="58" y="61" width="584"  height="200" creationComplete="setColors(event)" styleName="myTabStyle">
  <pages:One  label="ThisOne" id="on开发者_C百科e"  name="One"/>
  <pages:Two label="Twoooooooooooh" id="two"  width="584" name="two" />
  <pages:Three label="Threeeeeeeeh" id="three"  width="583" name="three" />
</mx:TabNavigator>

and

my pageStyles.css file is:

.myTabStyle {
 tabStyleName: "myTabs"; 

 corner-radius:15;
}

.myTabs {
 backgroundColor: #FF0080;
 corner-radius:10;
 focusRoundedCorners: "tl tr";
 skin:ClassReference('mx.skins.spark.ButtonSkin'); 
 chromeColor: #FF0080;  /* this is the tab widget itself, not the content */
 border-style:outset;
}

As you can see I have the "focusRoundedCorners" to point to top-right and top-left but no luck. What I got is:

What am I doing wrong guys??

Thanks in advance.

Have a look at this tool http://www.wabysabi.com/flex/enhancedbuttonskin/

I would guess that the focus part of the focusRoundedCorners refers to how it should be when it has focus only..

So here is the solution.

You can write you own button skin or use the one here http://www.wabysabi.com/flex/enhancedbuttonskin/ named EnhancedButtonSkin.as (right-click, View-Source). Then declare your TabNavigator component and specify its tabStyleName.

<mx:TabNavigator y="0" height="100%" right="0" left="0" id="navigator" tabStyleName="tab">

And now the css:

 <fx:Style>
  .tab
  {
   upSkin:ClassReference('com.EnhancedButtonSkin');
   overSkin:ClassReference('com.EnhancedButtonSkin');
   downSkin:ClassReference('com.EnhancedButtonSkin');
   disabledSkin:ClassReference('com.EnhancedButtonSkin');
   selectedUpSkin:ClassReference('com.EnhancedButtonSkin');
   selectedOverSkin:ClassReference('com.EnhancedButtonSkin');
   selectedDownSkin:ClassReference('com.EnhancedButtonSkin');
   selectedDisabledSkin:ClassReference('com.EnhancedButtonSkin');

   cornerRadii: 5, 5, 0, 0;
   borderColors: #CC0000, #000000;
   overBorderColors: #003399, #003399;
   selectedBorderColors: #666666, #FFFFFF;
   borderThickness: 1;
   borderAlpha: 1;
   fillColors: #CC3300, #F98900;
   fillAlphas: 1, 1;
   fillColorRatios: 0, 255;
   overFillColors: #999999, #FFFFFF;
   overFillAlphas: 1, 1;
   overFillColorRatios: 0, 255;
   selectedFillColors: #999999, #FFFFFF;
   selectedFillAlphas: 1, 1;
   selectedFillColorRatios: 111, 255;
   highlightAlphas: 0, 0;
   color: #000000;
   textRollOverColor: #000000;
   fontSize: 13;
  }
 </fx:Style>

This css will display:
