Question

我正在构建一个javaFx应用程序，ui是在fxml文件中构建的，我在其中使用了一个锚定窗格，一个HBox然后是一个表，但是我的表第一行出现了一条奇怪的蓝线并且周围。我也附了截图。我的fxml文件是： -

<?import java.lang.String?>
<?import javafx.collections.FXCollections?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.ComboBox?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.control.TableColumn?>
<?import javafx.scene.control.TableView?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.HBox?>

 </children>
</AnchorPane>

Answer 1

您的表格是您布局中的第一个项目，并且具有焦点。这就是它突出的原因。此外，您的布局中有HBox，但其中没有任何内容。通常，您应该使用自动处理布局的容器，而不是绝对定位节点。

这是您的场景的另一种布局，可以让您的生活更轻松。
