一个简单的解决方案是将小部件的宽度和高度设置为1，然后依赖网格选项来拉伸它以填充其容器。因为它的自然大小比它所在的细胞小，所以不会导致细胞生长。你知道吗

提示：“。。。无论“调整大小”：

虽然依赖于从自动化tkguimvc可视部件中暴露出来的最常见公共方法的行为/服务是很好的，但现实世界的布局复杂性可能会让我们陷入死胡同。你知道吗

尝试一种硬编码的编程方式从Tk GUI MVC控制器部件的新的、更改的内部值自动特别重新计算/重新构建Tk GUI MVC可视部件：

 master.bind( '<Configure>', aResizeCallbackHANDLER( ) )  # MVC-Controller Part TRIGGER

 def aResizeCallbackHANDLER( self, anEvent ):             # Reactor:
     # inspect <anEvent>.{}                               # .bind()-bound actor
     # and     <anEvent>.widget.{}                        # details from
     # incl.   <anEvent>.widget.<Tree-sub-element>.{}     # Tk-GUI-MVC-Model Part
     #
     #         <anEvent>.widget      <  system-assigned <widget>-instance
     #                  .height      on-{ <Configure> }
     #                  .width       on-{ <Configure> }
     #                  .serial      <  system-assigned Integer
     #                  .time        <  system-assigned Integer ( .inc each msec )
     # .
     # ..
     # ...
     # Act upon changes and enforce new, re-calculated values
     #                      into sub-ordinated geometry
     # ...
     #

这个原则是健壮的，不依赖于tkguimvc元素的任何“隐藏”的相互关系。你知道吗

要设置文本小部件的宽度：

text = Text(frame, width=20)

默认情况下，宽度设置为80个字符。请注意，该值不是常量，因此小部件的大小调整正确。你知道吗
