【问题描述】：
我有一个问题，我有一个应该执行一些代码的事件处理程序，除了代码之外，事件处理程序接受一个 MouseEvent 并且将调用它的事件是 onMouseClicked 事件，每次我尝试运行我得到的程序一个例外，如果我删除 MouseEvent 并将其保留为空或放置任何其他类型的事件，例如 Event 或 ActionEvent 它可以工作，但这不合逻辑加上我需要鼠标事件，因为然后我将检查在我的代码。我查看了其他有相同问题的人，我按照他们的答案做了所有的事情，但没有奏效。
异常 + 堆栈跟踪：
javafx.fxml.LoadException: Error resolving onMouseClicked='#maginfyRecord', either the event handler is not in the Namespace or there is an error in the script.

事件处理程序如下：
@FXML
public void magnifyRecord(MouseEvent event) {
if ((event.getButton()== event.BUTTON2)) {
TextArea area = new TextArea();
area.setText(selectedTable.getSelectionModel().getSelectedItem().toString());
JFXPopup popup = new JFXPopup();
popup.setPopupContent(area);
popup.show(selectedTable);
popup.show(selectedTable, event.getX(), event.getY());
}
}
这是这部分的 fxml：
<Tab fx:id="toDoListTab" onSelectionChanged="#switchTab" text="To Do List">
<content>
<StackPane prefHeight="150.0" prefWidth="200.0">
<children>
<TableView fx:id="toDoListTable" prefHeight="200.0" prefWidth="200.0" />
</children>
</StackPane>
</content>
</Tab>
<Tab fx:id="notesTab" onSelectionChanged="#switchTab" text="Notes">
<content>
<StackPane prefHeight="150.0" prefWidth="200.0">
<children>
<TableView fx:id="notesTable" prefHeight="200.0" prefWidth="200.0" />
</children>
</StackPane>
</content>
</Tab>
<Tab fx:id="contactsTab" onSelectionChanged="#switchTab" text="Contacts">
<content>
<StackPane prefHeight="150.0" prefWidth="200.0">
<children>
<TableView fx:id="contactsTable" onMouseClicked="#magnifyRecord" prefHeight="200.0" prefWidth="200.0" />
</children>
</StackPane>
</content>
</Tab>
<Tab fx:id="locationsTab" onSelectionChanged="#switchTab" text="Locations">
<content>
<StackPane prefHeight="150.0" prefWidth="200.0">
<children>
<TableView fx:id="locationsTable" prefHeight="200.0" prefWidth="200.0" />
</children>
</StackPane>
</content>
</Tab>
<Tab fx:id="productsTab" onSelectionChanged="#switchTab" text="Products">
<content>
<StackPane prefHeight="150.0" prefWidth="200.0">
<children>
<TableView fx:id="productsTable" prefHeight="200.0" prefWidth="200.0" />
</children>
</StackPane>
</content>
</Tab>
我尝试将代码完全注释掉，没有任何变化，它只有在我删除 MouseEvent 或用任何其他事件替换它时才有效
我正在使用 Netbeans + JDK 8 + Scene Builder + jfoenix 库
【问题讨论】：
-
发布整个 fxml 和控制器类，不要在这里发布它使用 pastebin 或其他东西链接它
-
@th3sp33dst3r 好的，我添加了它。
-
@th3sp33dst3r 我现在检查了一下，原来这是问题所在，这对我来说非常愚蠢，我已经尝试解决这个问题很长时间了。在您发表评论后，我发现我为 MouseEvent 导入了另一个导入，您可以将此评论作为答案，我会支持并接受它，因为您确实值得这样做，您甚至在没有看到导入语句的情况下怀疑该问题
