我制作了一个简单的电子邮件客户端,但是有一个问题:将元素设置为AnchorPane
时,它仅设置了最后一个元素,因此我认为存在度量错误的问题。我检查了不止一次,但是正如您所看到的,这些元素之间的分隔很好:
这是我将元素放入锚定窗格的方式:
public void start(Stage stage) throws Exception {
FXMLLoader listLoader = new FXMLLoader(getClass().getResource("lista.fxml"));
FXMLLoader textareaLoader = new FXMLLoader(getClass().getResource("textarea.fxml"));
FXMLLoader fieldLoader = new FXMLLoader(getClass().getResource("textfield.fxml"));
FXMLLoader menuLoader = new FXMLLoader(getClass().getResource("menubar.fxml"));
FXMLLoader buttonLoader = new FXMLLoader(getClass().getResource("button.fxml"));
AnchorPane root = new AnchorPane(listLoader.load(), textareaLoader.load(), fieldLoader.load(), menuLoader.load(), buttonLoader.load());
这些是具有所有坐标的FXML文件:
<AnchorPane xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="mailbox.ListController">

<ListView fx:id="listView" layoutY="31.0" prefHeight="371.0" prefWidth="239.0" />

答案 0 :(得分:1)
Blue represents AnchorPane of button.fxml
我为button.fxml
AnchorPane
添加了蓝色背景。
问题出在按钮的layoutX
和layoutY
上;按钮的坐标是相对于AnchorPane
的{{1}}的左上角计算的,而不是相对于button.fxml
的{{1}}的计算。这会导致AnchorPane
隐藏其后面的组件(如蓝色所示),因此list.xml
将消耗鼠标的输入事件。
要解决此问题(有比这更好的布局方法,只是临时修复),请在AnchorPane
中使用此代码
AnchorPane
上面的代码将开始在您期望的位置布置按钮,并且为了简化起见,我将它们包装在Vbox中。
关于2个节点的碰撞检查,请使用
button.fxml
