GWT中的TabPanel和TabLayoutPanel有什么不同 [英] What's the difference between TabPanel and TabLayoutPanel in GWT

问题描述

GWT中的TabPanel和TabLayoutPanel有什么区别？我无法在Google中找到答案，并且很难理解阅读文档。

解决方案

TabLayoutPanel 是一个布局面板：从外部输入的大小，它必须被给予明确的维度并在它们发生变化时得到通知（ RequiresResize ），同样会调整其子元素的大小并通知它们（ ProvideResize ）。

TabPanel 不是;它的大小从内到外：它将根据选定选项卡中小部件的大小自行调整大小。

解决方案

TabLayoutPanel is a layout panel: it's sized from the outside-in, it has to be given explicit dimensions and be notified when they changed (RequiresResize), and similarly will resize its children and notify them when it does so (ProvidesResize).

TabPanel is not; it's sized from the inside-out: it'll resize itself depending on the size of the widget in the selected tab.
