GXT 3网格滚动问题 [英] GXT 3 grid scrolling issue

问题描述

我正在使用GXT 3.0.0b。

I'm using GXT 3.0.0b.

我在ContentPanel上有一个Grid。当我明确设置ContentPanel的宽度时，滚动没有问题。但是，当我将网格放入VerticalLayoutContainer中时，网格的垂直滚动条消失，只能用鼠标滚轮滚动。

I have a Grid on ContentPanel. When I set ContentPanel width explicitly there is no problem with scrolling. But when I put grid in VerticalLayoutContainer the vertical scrollbar of the grid disappears and scrolling is possible only with mouse wheel.

有人知道如何解决这个问题吗？

Does anybody know how to solve this problem?

推荐答案

最后我设法解决了这个问题。答案很优雅：当我将网格添加到VerticalLayoutContainer时，我应该指定VerticalLayoutData参数。

Finally I've managed to solved this problem. The answer was rather elegant: when I added grid to VerticalLayoutContainer I should specify VerticalLayoutData parameter.

示例：

Example:

verticalLayoutContainer.add(grid, new VerticalLayoutData(1, 1));

您也可以传递分数，例如0.6将宽度（或高度）设置为60％。如果您传递-1，则组件将拥有它自己的默认像素大小。

You can also pass fraction, for example, 0.6 will set width (or height) to 60%. If you pass -1 then component will have it's own default pixel size.
