当我调整大小时,如何才能很好地排列组件. 我在GUI中使用FXML
When i resize how can i nicely arrange the components. im using FXML for the GUI
FXML代码
<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="style.LoginController">
<children>
<Button fx:id="login" layoutX="250.0" layoutY="242.0" mnemonicParsing="false" onAction="#login" prefHeight="32.0" prefWidth="101.0" text="Login" />
<ImageView fx:id="img2" fitHeight="32.0" fitWidth="32.0" layoutX="109.0" layoutY="184.0" pickOnBounds="true" preserveRatio="true">

</ImageView>
<Label fx:id="title" alignment="CENTER" focusTraversable="false" layoutX="166.0" layoutY="48.0" opacity="0.83" prefHeight="42.0" prefWidth="269.0" styleClass="title" text="Label" textAlignment="CENTER" textOverrun="CENTER_ELLIPSIS">

<Font name="Arial Narrow" size="36.0" />
</font>
</Label>
<TextField fx:id="txtusername" layoutX="159.0" layoutY="126.0" prefHeight="32.0" prefWidth="283.0" promptText="Username" styleClass="fields" />
<PasswordField fx:id="txtpassword" layoutX="159.0" layoutY="183.0" prefHeight="32.0" prefWidth="283.0" promptText="Password" styleClass="fields" />
<ImageView fx:id="img1" fitHeight="32.0" fitWidth="32.0" layoutX="109.0" layoutY="126.0" pickOnBounds="true" preserveRatio="true">

</ImageView>
<ProgressIndicator fx:id="progress" layoutX="197.0" layoutY="120.0" minHeight="0.0" minWidth="0.0" prefHeight="128.0" prefWidth="188.0" progress="0.0" styleClass="progressind" />

</AnchorPane>
推荐答案
问题是因为您使用AnchorPane作为根窗格.虽然,您可以在这种情况下使用AnchorPane,但我个人并不喜欢它,因为您需要做很多事情才能使其正确.有更简单的方法可以做,这就是我要告诉你的.
The problem is because you are using AnchorPane as your root pane. Though, you can use AnchorPane for scenarios like this, I personally do not prefer it because you need to do a lot of things to get it right. There are easier ways to do and that is what I am gonna show you.
来自Javadocs:
From the Javadocs :
AnchorPane允许将子节点的边缘锚定到与锚定窗格的边缘偏移的位置.
AnchorPane allows the edges of child nodes to be anchored to an offset from the anchor pane's edges.
解决方案
使用其他布局.可能是 GridPane 或 VBox .这些布局具有子对齐而不是锚,这使孩子可以对齐到特定位置.
Use a different layout. May be a GridPane or VBox. These layouts have child alignment instead of anchors, which allow the children to be aligned to a particular position.
要调整孩子的尺寸,可以设置 VGrow 属性.
For re-sizing your children, you can set the HGrow / VGrow property on them.
示例
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<VBox alignment="CENTER" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" spacing="20.0" style="-fx-background-color: DARKCYAN;" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1">
<children>
<Label text="Easy Doctor" />
<TextField promptText="Username" />
<TextField promptText="Password" />
</children>
<padding>
<Insets bottom="50.0" left="50.0" right="50.0" top="50.0" />
</padding>
</VBox>
