自定义组件中的CommitProperties不适用于百分比宽度

commitProperties

override protected function commitProperties():void {
        super.commitProperties();

        //some stuff ...

        TextInput(textInput).setSelection(cursorPosition, cursorPosition);
        if (cursorPosition == textInput.text.length || cursorPosition == 0) {
            TextInput(textInput).horizontalScrollPosition = (cursorPosition == 0) ? 0 : textInput.width;
        }
    }

textInput.width

override protected function measure():void {
        super.measure();
        measuredWidth = 160;
    }
