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).
TabLayoutPanel是一个布局面板：它从外向内调大小，它必须给出明确的尺寸，并在它们发生变化时通知（RequiresResize），同样会调整它的子节点并在它发生时通知它们（ProvideResize）。
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.
TabPanel不是;它的大小由内而外：它将根据所选标签中小部件的大小自行调整大小。

除了托马斯所说的话
In GWT, To layout the widgets in the screen there are two kind of panels: Panels ( Eg: TabPanel ) and Layout Panels ( Eg: TabLayoutPanel )
在GWT中，要在屏幕中布置小部件，有两种面板：面板（例如：TabPanel）和布局面板（例如：TabLayoutPanel）
Panels or Non-layout panels
These panels (TabPanel, DockPanel, Horizontal panel, Vertical Panel, AbsolutePanel ... ) allow you to layout widgets in an explicit manner. It will render the widgets as imagined ( provided correct imagination ;) ). Its child widgets are not automatically resized when the browser resizes.
这些面板（TabPanel，DockPanel，水平面板，垂直面板，AbsolutePanel ...）允许您以显式方式布局窗口小部件。它会像想象的那样呈现小部件（提供正确的想象力;））。浏览器调整大小时，其子窗口小部件不会自动调整大小。
Layout panels
These Panels (TabLayoutPanel, DockLayoutPanel, ScrollPanel, FlexTable, SplitLayoutPanel... ) allow you to layout widgets in the explicit manner but also resize the child widget when the browser resizes as each of them implements RequiresResize and/or providesResize provided you maintain Layout panels hierarchy throughout and provide the size of panels and widgets in percentages.
这些面板（TabLayoutPanel，DockLayoutPanel，ScrollPanel，FlexTable，SplitLayoutPanel ...）允许您以显式方式布局窗口小部件，但也可以在浏览器调整大小时调整子窗口小部件的大小，因为每个窗口都实现了RequiresResize和/或provideResize，前提是您维护布局面板整个层次结构，并以百分比形式提供面板和小部件的大小。
