在锚点面板中，将工具提示添加到 /> d-color:#272822;"><?xml version="1.0" encoding="UTF-8"?> <?import javafx.scene.control.Button?> <?import javafx.scene.control.Label?> <?import javafx.scene.control.MenuButton?> <?import javafx.scene.control.MenuItem?> <?import javafx.scene.control.ScrollBar?> <?import javafx.scene.image.Image?> <?import javafx.scene.image.ImageView?> <?import javafx.scene.layout.AnchorPane?> <AnchorPane id="AnchorPane" prefHeight="800.0" prefWidth="1855.0" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="calibre.FXMLDocumentController"> <children> <Button fx:id="button" layoutX="6.0" layoutY="7.0" onAction="#handleAddBookButtonAction" prefHeight="32.0" prefWidth="200.0" text="Add Books"> <tooltip><Tooltip text="my tooltip" /></tooltip> </Button> <Label fx:id="label" layoutX="6.0" layoutY="7.0" minHeight="16" minWidth="69" /> <Button layoutX="274.0" layoutY="7.0" mnemonicParsing="false" onAction="#handleEditMetadataButtonAction" prefHeight="32.0" prefWidth="200.0" stylesheets="@style.css" text="Edit Metadata" /> <Button layoutX="564.0" layoutY="7.0" mnemonicParsing="false" onAction="#handleFetchNewsButtonAction" prefHeight="32.0" prefWidth="200.0" text="Fetch News" /> <Button layoutX="839.0" layoutY="7.0" mnemonicParsing="false" onAction="#handleRemoveButtonAction" prefHeight="32.0" prefWidth="200.0" text="Remove" /> <Button layoutX="1225.0" layoutY="9.0" mnemonicParsing="false" onAction="#handleLibraryButtonAction" prefHeight="32.0" prefWidth="200.0" text="Library" /> <MenuButton layoutX="1607.0" layoutY="11.0" minWidth="200.0" mnemonicParsing="false" text="MenuButton" textFill="#eeeeee"> <items> <MenuItem mnemonicParsing="false" text="Action 1" /> <MenuItem mnemonicParsing="false" text="Action 2" /> </items> </MenuButton> <ImageView fitHeight="564.0" fitWidth="358.0" layoutX="747.0" layoutY="166.0" pickOnBounds="true" preserveRatio="true"> <image> <Image url="@Books/1.png" /> </image> </ImageView> <ScrollBar layoutX="54.0" layoutY="773.0" prefHeight="18.0" prefWidth="1781.0" /> <ImageView fitHeight="564.0" fitWidth="358.0" layoutX="149.0" layoutY="180.0" pickOnBounds="true" preserveRatio="true"> <image> <Image url="@Books/4.jpg" /> </image> </ImageView> <ImageView fitHeight="564.0" fitWidth="358.0" layoutX="1325.0" layoutY="159.0" pickOnBounds="true" preserveRatio="true"> <image> <Image url="@Books/3.png" /> </image> </ImageView> <Button layoutX="382.0" layoutY="722.0" mnemonicParsing="false" onAction="#handleReadHemingwayButtonAction" onDragOver="#handleReadBookHoverTip" text="Read" /> <Button layoutX="985.0" layoutY="722.0" mnemonicParsing="false" onAction="#handleReadGentlemanButtonAction" text="Read" /> <Button layoutX="1580.0" layoutY="731.0" mnemonicParsing="false" onAction="#handleReadFlowersButtonAction" text="Read" /> </children> </AnchorPane> 按钮上的代码已经在你的FXML文件中。如果您遇到工具提示在锚点面板中不起作用的问题，可能是由于某些其他因素引起的。检查您的代码是否有错误，确保在FXML控制器中正确处理按钮的handleAddBookButtonAction动作，以便工具提示能够显示。同时，锚点面板本身并不影响工具提示的显示

I have some buttons inside an anchorpane and want to know how I can add Tooltips to a button.

    &lt;/children&gt;
&lt;/AnchorPane&gt;


But it says tooltips don't exist in Anchorpanes.

Does this mean I need to change from an Anchorpane, if so what are my alternatives.

I'm doing this in Netbeans.
Warm Regards

如果您有控制器类，您可以在initialize方法内从该方法中获取tooltip。
yourBtnId.setTooltip(new Tooltip("添加客户"));

如果您正在使用XML编辑，
<Button>
    <tooltip>
        <Tooltip textAlignment="CENTER" text="你好" />
    </tooltip>
</Button>

在您的XML文件中，删除所有的button标签，然后粘贴如下内容：
<Button fx:id="button" layoutX="6.0" layoutY="7.0" onAction="#handleAddBookButtonAction" prefHeight="32.0" prefWidth="200.0" text="添加图书">
    <tooltip>
        <Tooltip text="我的工具提示" />
    </tooltip>
</Button>

您的错误是Button标签在添加工具提示/&gt;之前已经关闭。

英文:
if you have controller class you can get tooltip from this method inside the initialize method
yourBtnId.setTooltip(new Tooltip(&quot;Add Customer&quot;));

If you are using XML editing
&lt;Button&gt;
     &lt;tooltip&gt;&lt;Tooltip  textAlignment=&quot;CENTER&quot; text=&quot;HELLO&quot; /&gt;&lt;/tooltip&gt;
&lt;/Button&gt;

in your XML file remove your all button tag and paste this
&lt;Button fx:id=&quot;button&quot; layoutX=&quot;6.0&quot; layoutY=&quot;7.0&quot; onAction=&quot;#handleAddBookButtonAction&quot; prefHeight=&quot;32.0&quot; prefWidth=&quot;200.0&quot; text=&quot;Add Books&quot;&gt; 
            &lt;tooltip&gt;&lt;Tooltip text=&quot;my tooltip&quot; /&gt;&lt;/tooltip&gt;

&lt;/Button&gt;

your mistake is Button tag is closing before you add the tooltip /&gt;
