如何在JavaFX中实现TableView的分页? [英] How to implement paging for a TableView in JavaFX?
问题描述
如何使用javaFx tableView实现分页显示?
你必须使用分页控制并实现页面工厂。为每个应显示的页面调用工厂,您可以使用其参数pageIndex为TableView提供项目的子列表:
TableView table = ...
private Node createPage(int pageIndex){
int fromIndex = pageIndex * rowsPerPage;
int toIndex = Math.min(fromIndex + rowsPerPage,data.size());
table.setItems(FXCollections.observableArrayList(data.subList(fromIndex,toIndex)));
返回新的BorderPane(表);
}
@Override
public void start(最后阶段阶段)抛出异常{
分页分页=新分页((数据) .size()/ rowsPerPage + 1),0);
pagination.setPageFactory(this :: createPage);
...
}
可在此处找到完整的可运行示例:

PS:我关注了jewelsea链接到Oracle JavaFX论坛,示例非常糟糕。我想在这里提供一个清理过的例子。
I have JavaFx TableView, and want to implement tableView paging display. How to javaFx tableView Implement paging display?
You have to use the Pagination control and implement a page factory. The factory is called for every page that should be displayed and you can use its parameter, the pageIndex, to provide a sublist of items to the TableView:
TableView table = ...
private Node createPage(int pageIndex) {
int fromIndex = pageIndex * rowsPerPage;
int toIndex = Math.min(fromIndex + rowsPerPage, data.size());
table.setItems(FXCollections.observableArrayList(data.subList(fromIndex, toIndex)));
return new BorderPane(table);
}
@Override
public void start(final Stage stage) throws Exception {
Pagination pagination = new Pagination((data.size() / rowsPerPage + 1), 0);
pagination.setPageFactory(this::createPage);
...
}
A complete runnable example can be found here: https://gist.github.com/timbuethe/7becdc4556225e7c5b7b
PS: I followed jewelsea link to the Oracle JavaFX Forums, and the example is really bad. I wanted to provide an cleaned up example here.
