GWT HorizontalPanel setSpacing?
提问by aadidasu
Is there a way to set padding on GWT's HorizontalPanel?
有没有办法在 GWT 上设置填充HorizontalPanel？
I wanted to just have 20px left padding and then add few buttons.
Currently I can only add setSpacing()and that puts padding on top, left, right and bottom.
我只想有 20 像素的左填充，然后添加几个按钮。
目前我只能添加setSpacing()并在顶部、左侧、右侧和底部放置填充。

You could (and should) use CSS for this, something like:
您可以（并且应该）为此使用 CSS，例如：
.paddedHorizontalPanel {
padding-left: 20px;
}
And if you want every Buttonin that HorizontalPanelto be 20pxapart, then you can try this instead:
如果你想每一个Button在HorizontalPanel要20px分开，那么你可以试试这个：
.paddedHorizontalPanel .gwt-Button {
margin-left: 20px;
}
And then add this style to you HorizontalPanelvia hPanel.addStyleName("paddedHorizontalPanel");More on CSS and GWT in the docs.
然后HorizontalPanel通过文档hPanel.addStyleName("paddedHorizontalPanel");中的More on CSS 和 GWT添加此样式。
PS: AFAIK, not including setPadding was a concious choice on part of the GWT team - they wanted to leave the styling of the application entirely up to CSS.
PS：AFAIK，不包括 setPadding 是 GWT 团队的一个有意识的选择 - 他们希望将应用程序的样式完全留给 CSS。

In worst case you can always do :
在最坏的情况下，您始终可以执行以下操作：
HorizontalPanel p = new HorizontalPanel();
p.getElement().getStyle().setPadding(20, Unit.PX);
