我面临一个显示问题，场景生成器的输出看起来与运行程序时的实际输出不同。这是一个例子: 左边是场景构建器的，右边是在 netbeans 上运行程序的。来自场景构建器的(左图)基于黑色方 block 具有相等的边。另一方面，来自 netbeans 的(右图)基于黑匣子具有不等边。还可以清楚地看到，右图像的尺寸比左图像大。我怎样才能解决这个问题？如何显示正确的图像以使两边相等？为什么在netbeans上运行时显示不同？

最佳答案
您将 Label 的位置和大小设置为 Pane 中的绝对大小，这意味着 Label 保留其左上角坐标，但根据其首选大小调整大小。
您应该使用父布局来调整其可调整大小的子布局，而不是这样做。 VBox。
将 Pane 替换为如下内容:
<VBox alignment="TOP_CENTER" prefHeight="148.0" prefWidth="300.0" styleClass="loginPaneBackground" AnchorPane.bottomAnchor="291.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" spacing="12.0">
<children>
<ImageView fitHeight="70.0" fitWidth="70.0" pickOnBounds="true" preserveRatio="true">
<image>
<Image url="@../../resources/imgs/login_img.png" />
</image>
</ImageView>
<Label fx:id="isConnected" alignment="CENTER" maxWidth="Infinity" text="Login" textFill="WHITE">
<font>
<Font name="Roboto Regular" size="24.0" />
</font>
<styleClass>
<String fx:value="robotBold" />
<String fx:value="loginLabel" />
</styleClass>
</Label>
</children>
<padding>
<Insets bottom="24.0" top="14.0" />
</padding>
</VBox>
