我发现了 GWT 的 CustomScrollPanel 以及如何自定义滚动条,但我找不到任何示例或如何设置它。是否有任何示例显示正在使用的自定义滚动条?

这是您自定义本机滚动条的方式,但是您也可以开发自己的滚动条类来实现可定制性更高的 VerticalScrollbar 和 HorizontalScrollbar。
资源(风格)定义:
public class ScrollResourcesContainer {
public interface ScrollPanelResources extends CustomScrollPanel.Resources
{
@Override
@Source( { "ScrollPanel.css", CustomScrollPanel.Style.DEFAULT_CSS } )
CustomScrollPanel.Style customScrollPanelStyle();
}
public interface HorizontalResources extends NativeHorizontalScrollbar.Resources
{
@Override
@Source( { "HorizontalScrollbar.css", NativeHorizontalScrollbar.StyleTransparant.DEFAULT_CSS } )
NativeHorizontalScrollbar.Style nativeHorizontalScrollbarStyle();
}
public interface VerticalResources extends NativeVerticalScrollbar.Resources
{
@Override
@Source( { "VerticalScrollbar.css", NativeVerticalScrollbar.StyleTransparant.DEFAULT_CSS } )
NativeVerticalScrollbar.Style nativeVerticalScrollbarStyle();
}
}
通过使用CustomScrollPanel
:
CustomScrollPanel csp = new CustomScrollPanel((ScrollResourcesContainer.ScrollPanelResources) GWT.create(ScrollResourcesContainer.ScrollPanelResources.class));
csp.setHorizontalScrollbar(new NativeHorizontalScrollbar((HorizontalResources) GWT.create(HorizontalResources.class)),
AbstractNativeScrollbar.getNativeScrollbarHeight());
csp.setVerticalScrollbar(new NativeVerticalScrollbar((VerticalResources) GWT.create(VerticalResources.class)),
AbstractNativeScrollbar.getNativeScrollbarWidth());

要在 gwt 中获得垂直滚动条的光滑滚动条,您需要在VerticalScrollbar.css中添加以下代码。这对 IE 不起作用,就像 gmail 一样。
/* Turn on a 16x16 scrollbar */
::-webkit-scrollbar {
width: 16px;
height: 16px;
}
/* Turn on single button up on top, and down on bottom */
::-webkit-scrollbar-button:start:decrement,
::-webkit-scrollbar-button:end:increment {
display: block;
}
/* Turn off the down area up on top, and up area on bottom */
::-webkit-scrollbar-button:vertical:start:increment,
::-webkit-scrollbar-button:vertical:end:decrement {
display: none;
}
/* Place The scroll down button at the bottom */
::-webkit-scrollbar-button:end:increment {
background-image: url(images/scroll_cntrl_dwn.png);
}
/* Place The scroll up button at the up */
::-webkit-scrollbar-button:start:decrement {
background-image: url(images/scroll_cntrl_up.png);
}
/* Top area above thumb and below up button */
::-webkit-scrollbar-track-piece:vertical:start {
background-image: url(images/scroll_gutter_top.png), url(images/scroll_gutter_mid.png);
background-repeat: no-repeat, repeat-y;
}
/* Bottom area below thumb and down button */
::-webkit-scrollbar-track-piece:vertical:end {
background-image: url(images/scroll_gutter_btm.png), url(images/scroll_gutter_mid.png);
background-repeat: no-repeat, repeat-y;
background-position: bottom left, 0 0;
}
/* The thumb itself */
::-webkit-scrollbar-thumb:vertical {
height: 56px;
-webkit-border-image: url(images/scroll_thumb.png) 8 0 8 0 stretch stretch;
border-width: 8 0 8 0;
}

如果有人对垂直/水平的 CSS 感兴趣,这就是我正在使用的。
水平滚动条.css
