我正在尝试使用 fxml 添加一个新选项卡。
我已经在 tabPane 中添加了标签。
int numTabs = tabPane.getTabs().size();
Tab tab = new Tab("Tab " + (numTabs + 1));
tabPane.getTabs().add(tab);
但是我不能用它加载 FXML
tabPane.getTabs().addAll((Tab)FXMLLoader.load(this.getClass().getResource("tab.fxml")));`
错误:javafx.fxml.LoadException:
tab.fxml:
<TabPane fx:id="tabPane" layoutX="14.0" layoutY="105.0"
prefHeight="200.0" prefWidth="292.0" tabClosingPolicy="UNAVAILABLE">
<tabs>
<Tab text="Untitled Tab">
<content>
<AnchorPane id="Content" minHeight="0.0" minWidth="0.0" prefHeight="180.0" prefWidth="200.0">
<children>
<Button layoutX="118.0" layoutY="74.0" mnemonicParsing="false" text="Button" />
</children>
</AnchorPane>
</content>
</Tab>
</tabs>
</TabPane>
编辑:我试过删除 <TabPane>标记但没有用。

最佳答案
尝试一下:
<Tab text="Untitled Tab">
<content>
<AnchorPane id="Content" minHeight="0.0" minWidth="0.0" prefHeight="180.0" prefWidth="200.0">
<children>
<Button layoutX="118.0" layoutY="74.0" mnemonicParsing="false" text="Button" />
</children>
</AnchorPane>
</content>
</Tab>
关于java - 将选项卡添加到 TabPane JavaFX，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39602879/
