In FLEX3, we can use TitleTextStyleName to modify the titlebar text format.
But in Flex4, this attribute be removed, i use spark.skins.spark.SparkChromeWindowedApplicationSkin as windowedapplication's skin
I found the titlebar control, but i don't find any style attribute about font in TitleBar control.
how can i modify the title text format?
Finally, I used build-in titlebar skin for titlebar to customize title text.
Because spark title bar don't have any style for font, so setting stylename is not a good method.
You should use skin to change titlebar's apprearance.
so you should use two skin to customize the windowedapplication when you want to use your own UI solution.
I think FLEX4 is more complicative than FLEX 3 in skin (That's what FLEX 4 want to do)
It's not easy for developers who want to tranfer their project from FLEX 3 to FLEX4 when they use more customized UI.
