Layout - BoxLayout

BoxLayout

BoxLayout1, 水平與垂直Box, X_AXIS, Y_AXIS
BoxLayout2, 自動推開元件: Glue, HorizontalGlue, VerticalGlue
BoxLayout3, 固定大小的分隔: HorizontalStrut, VerticalStrut
BoxLayout4, 有長跟寬的分隔: RigidArea
BoxLayout5, 有最小最大跟預設大小的RigidArea: Box.Filler
BoxLayout6, Box中在裝Box: HorizontalBox, VerticalBox

   X_AXIS：从左到右水平布置组件。
   Y_AXIS：从上到下垂直布置组件。
   LINE_AXIS：根据容器的 ComponentOrientation 属性，按照文字在一行中的排列方式布置组件。如果容器的 ComponentOrientation 表示水平，则将组件水平放置，否则将它们垂直放置。对于水平方向，如果容器的 ComponentOrientation 表示从左到右，则组件从左到右放置，否则将它们从右到左放置。对于垂直方向，组件总是从上到下放置的。
   PAGE_AXIS：根据容器的 ComponentOrientation 属性，按照文本行在一页中的排列方式布置组件。如果容器的 ComponentOrientation 表示水平，则将组件垂直放置，否则将它们水平放置。对于水平方向，如果容器的 ComponentOrientation 表示从左到右，则组件从左到右放置，否则将它们从右到左放置。对于垂直方向，组件总是从上向下放置的。
