this.el.alignTo(Ext.getBody(), 'br-br');这句话的‘br-br’是什么意思
alignTo( element, [position], [offsets], [animate] ) : Ext.Element
Aligns this element with another element relative to the specified anchor points. If the other element is the document it aligns it to the viewport. The position parameter is optional, and can be specified in any one of the following formats:
Blank: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").
One anchor (deprecated): The passed anchor position is used as the target element's anchor point. The element being aligned will position its top-left corner (tl) to that point. This method has been deprecated in favor of the newer two anchor syntax below.
Two anchors: If two values from the table below are passed separated by a dash, the first value is used as the element's anchor point, and the second value is used as the target's anchor point.
In addition to the anchor points, the position parameter also supports the "?" character. If "?" is passed at the end of the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints. Following are all of the supported anchor positions:
Value Description
----- -----------------------------
tl The top left corner (default)
t The center of the top edge
tr The top right corner
l The center of the left edge
c In the center of the element
r The center of the right edge
bl The bottom left corner
b The center of the bottom edge
br The bottom right corner
Example Usage:
// align el to other-el using the default positioning ("tl-bl", non-constrained)
el.alignTo("other-el");
// align the top left corner of el with the top right corner of other-el (constrained to viewport)
el.alignTo("other-el", "tr?");
// align the bottom right corner of el with the center left edge of other-el
el.alignTo("other-el", "br-l?");
// align the center of el with the bottom left corner of other-el and
// adjust the x position by -6 pixels (and the y position by 0)
el.alignTo("other-el", "c-bl", [-6, 0]);
求解：关于c语言中，宏定义的问题。。。。
视你输入的数值（对象的长度），将其按4边界对齐。
例如若某个对象的长度为18，那么在为其分配空间时，通过NLMSG_ALIGN宏就可以计算出最接近其的4的倍数为((18+4-1) ~(3)) = 20，这样便为其申请/分配20字节空间。
这是32位微控制器/微处理器中为了防止非对齐操作产生Exception而添加的保护措施。
