TextInput, RichEditableText, NumericStepper等类型的控件在获得焦点后.

有时需要他失去焦点时stage.focus=null;不能完全做到,因为focusmanager里还保存着个lastFocus,程序再次激活时会自动把它重新设置为焦点.

解决方法:

use namespace mx_internal;

focusManager.mx_internal::lastFocus = null;

示例:

protected function mouseFocusChangeHandler(event:FocusEvent):void

{
　　if(stage && stage.focus && focusManager && focusManager.mx_internal::lastFocus == )
　　{
　　　　stage.focus=null;
　　　　focusManager.mx_internal::lastFocus = null;
　　}
}

<s:TextInput mouseFocusChange="mouseFocusChangeHandler(event)"/>
