实现方式

Java实现

    public static ToolBar demo1() {
        ToolBar toolBar = new ToolBar();
        // 布局方向
        toolBar.setOrientation(Orientation.VERTICAL);
        // 内边距
        toolBar.setPadding(new Insets(10, 10, 10, 10));

        for (int i = 1; i <= 10; i++) {
            Button btn = new Button("Button " + i);
            Separator separator = new Separator();
            toolBar.getItems().addAll(btn, separator);
        }

        return toolBar;
    }

fxml实现

<StackPane alignment="TOP_LEFT" prefHeight="400" prefWidth="600" xmlns="http://javafx.com/javafx/17.0.2-ea"
           xmlns:fx="http://javafx.com/fxml/1">
    <children>
        <ToolBar prefHeight="40.0" prefWidth="200.0">
            <items>
                <Button mnemonicParsing="false" text="Button 1"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 2"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 3"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 4"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 5"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 6"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 7"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 8"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 9"/>
                <Separator/>
                <Button mnemonicParsing="false" text="Button 10"/>
                <Separator/>
            </items>
        </ToolBar>
    </children>
</StackPane>
