如何从表列javafx中删除行 [英] How to delete row from table column javafx

问题描述

这些是我的表格列 课程和说明。如果单击某一行（该行变为活动/突出显示），并按下删除按钮，则应该删除该行，我该怎么做？

These are my table columns Course and Description. If one clicks on a row (the row becomes 'active'/highlighted), and they press the Delete button it should remove that row, how do I do this?

我的课程列的代码:(以及我添加到删除按钮的事件监听器？）

The code for my Course column: (and what event listener do I add to my delete button?)

@SuppressWarnings("rawtypes")
TableColumn courseCol = new TableColumn("Course");
courseCol.setMinWidth(300);
courseCol.setCellValueFactory(new PropertyValueFactory<Courses, String>("firstName"));

final Button deleteButton = new Button("Delete");

deleteButton.setOnAction(.....

推荐答案

只需从表格视图的项目列表中删除所选项目。如果您有

Just remove the selected item from the table view's items list. If you have

TableView<MyDataType> table = new TableView<>();

然后你做

deleteButton.setOnAction(e -> {
    MyDataType selectedItem = table.getSelectionModel().getSelectedItem();
    table.getItems().remove(selectedItem);
});
