GWT:DataGrid - 设置高度 100% 未正确呈现 [英] GWT: DataGrid - set height 100% not rendering properly

问题描述

我正在使用布局面板和数据网格.当我将数据网格高度设置为 100% 时，网格不会呈现.我的面板层次结构如下图

I am working with layout panels and datagrid. When I set the datagrid height to 100%, Grid is not rendering. My panel hierarchy looks like the following image

我做得对还是我搞砸了面板层次结构???

Am I doing it properly or I messed up the panel hierarchy???

父面板是简单的布局面板，里面我有拆分布局面板 -> 滚动面板 -> 数据网格

Parent panel is the simple layout panel, inside that I have split layout panel -> scrollpanel -> datagrid

推荐答案

DataGrid 需要放在一个 LayoutPanel 或 Panel 实现ProvidesResize 界面可见.ScrollPanel 实现了该接口.

DataGrid requires to be put in a LayoutPanel or Panel that implements the ProvidesResize interface to be visible. ScrollPanel implements that interface.

此外，从您的 DataGrid 到根元素/面板的这个 LayoutPanels 链必须是完整的.在您的面板层次结构中似乎就是这种情况.

Furthermore this chain of LayoutPanels from your DataGrid up to your root element/panel has to be unbroken. That seems to be the case in your panel hierarchy.

最后，您必须使用 RootLayoutPanel 而不是 RootPanel 来添加您的 LayoutPanels.
那么您是否确保将 SimpleLayoutPanel 添加到 RootLayoutPanel 中?

Finally you have to use the RootLayoutPanel instead of the RootPanel to add your LayoutPanels.
So did you make sure that you add your SimpleLayoutPanel to the RootLayoutPanel ?
