public static void hideHTMLEditorToolbars(final HTMLEditor editor)
{
editor.setVisible(false);
Platform.runLater(new Runnable()
{
@Override
public void run()
{
Node[] nodes = editor.lookupAll(".tool-bar").toArray(new Node[0]);
for(Node node : nodes)
{
node.setVisible(false);
node.setManaged(false);
}
editor.setVisible(true);
}
});

1这个很不错，因为你甚至看不出工具栏曾经在那里。 - Brad Turek

如果您使用不受支持的方法，您可以轻松地自定义工具栏。
正如Uluk在他的答案中所述，下面的这些方法不被官方支持。
import java.util.regex.Pattern;
import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.image.ImageView;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
public class HTMLEditorSample extends Application {
public static void main(String[] args) { launch(args); }
@Override public void start(Stage stage) {
final HTMLEditor htmlEditor = new HTMLEditor();
stage.setScene(new Scene(htmlEditor));
stage.show();
hideImageNodesMatching(htmlEditor, Pattern.compile(".*(Cut|Copy|Paste).*"), 0);
Node seperator = htmlEditor.lookup(".separator");
seperator.setVisible(false); seperator.setManaged(false);
}
public void hideImageNodesMatching(Node node, Pattern imageNamePattern, int depth) {
if (node instanceof ImageView) {
ImageView imageView = (ImageView) node;
String url = imageView.getImage().impl_getUrl();
if (url != null && imageNamePattern.matcher(url).matches()) {
Node button = imageView.getParent().getParent();
button.setVisible(false); button.setManaged(false);
}
}
if (node instanceof Parent)
for (Node child : ((Parent) node).getChildrenUnmodifiable())
hideImageNodesMatching(child, imageNamePattern, depth + 1);
}
}

如果有人真的想使用不支持的方法来隐藏工具栏，那么有一种更简单的方法可以实现这一点（我没有测试过这是否会在HTMLEditor控件中引起任何问题，因此请自行承担风险）。
package htmleditorsample;
import javafx.application.Application;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
public class HTMLEditorSample extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
final HTMLEditor htmlEditor = new HTMLEditor();
primaryStage.setScene(new Scene(htmlEditor));
primaryStage.show();
for (Node toolBar = htmlEditor.lookup(".tool-bar"); toolBar != null; toolBar = htmlEditor.lookup(".tool-bar")) {
((Pane) toolBar.getParent()).getChildren().remove(toolBar);
}
}
}

试试这个：
.html-editor .top-toolbar
{
-fx-max-width: 0px;
-fx-min-width: 0px;
-fx-pref-width: 0px;
-fx-max-height: 0px;
-fx-min-height: 0px;
-fx-pref-height: 0px;
-fx-opacity: 0;
}
.html-editor .bottom-toolbar
{
-fx-max-width: 0px;
-fx-min-width: 0px;
-fx-pref-width: 0px;
-fx-max-height: 0px;
-fx-min-height: 0px;
-fx-pref-height: 0px;
-fx-opacity: 0;

你应该能够隐藏工具栏上的按钮，甚至删除它们。
我会这样做：
我会这样做：
final Map map = new HashMap();
for (Node candidate: (htmlEditor.lookupAll("ToolBar"))) {
List list = ((ToolBar) candidate).getItems();
for (int i = 0; i < list.size(); i++) {
Node b = (Node) list.get(i);
map.put(map.size() + 1, b);
}
}
// So we've fetch all buttons (including separators) and assigned
// each an index number. Now then to hide an item:
((Node) map.get(2)).setVisible(false); // Hides copy button
((Node) map.get(13)).setVisible(false); // Hides bullets button
// Or to just completely remove them:
map.remove(18); // Removes font-menu-button
map.remove(25); // Removes editor-strike button- user241178

.tool-bar
{
/*-fx-visibility:hidden;
-fx-display:none; */
-fx-opacity: 0;
}
透明度有效，但菜单仍然处于活动状态。

这是一个相当古老的线程，但是大多数答案只能在较新的JDK上部分工作，因此这里是我基于该线程中某些概念编写的自定义HTML编辑器类。
import javafx.application.Platform;
import javafx.scene.Node;
import javafx.scene.control.ToolBar;
import javafx.scene.web.HTMLEditor;
import java.util.ArrayList;
import java.util.HashSet;
public class MinimalHTMLEditor extends HTMLEditor {
public MinimalHTMLEditor() {
super();
customizeHtmlEditor(this);
}
public static void customizeHtmlEditor(final HTMLEditor editor) {
editor.setVisible(false);
Platform.runLater(() -> {
ToolBar toolBar1 = (ToolBar) editor.lookup(".top-toolbar");
ToolBar toolBar2 = (ToolBar) editor.lookup(".bottom-toolbar");
HashSet<Node> nodesToKeep = new HashSet<>();
nodesToKeep.add(editor.lookup(".html-editor-numbers"));
nodesToKeep.add(editor.lookup(".html-editor-bullets"));
nodesToKeep.add(editor.lookup(".html-editor-foreground"));
nodesToKeep.add(editor.lookup(".html-editor-background"));
nodesToKeep.add(editor.lookup(".html-editor-bold"));
nodesToKeep.add(editor.lookup(".html-editor-italics"));
nodesToKeep.add(editor.lookup(".html-editor-underline"));
nodesToKeep.add(editor.lookup(".html-editor-strike"));
toolBar1.getItems().removeIf(n -> !nodesToKeep.contains(n));
toolBar2.getItems().removeIf(n -> !nodesToKeep.contains(n));
ArrayList<Node> toCopy = new ArrayList<>();
toCopy.addAll(toolBar2.getItems());
toolBar2.getItems().clear();
toolBar1.getItems().addAll(toCopy);
toolBar2.setVisible(false);
toolBar2.setManaged(false);
editor.setVisible(true);
});
}
}

奇怪！！！我尝试了你的代码，但它没有删除三个组合框："格式"、"字体"或"大小"。其中一个 ==> nodesToKeep.add(editor.lookup(".format-menu-button")); - Adalberto José Brasaca

您可以使用CSS删除特定的按钮，例如：
.html-editor-copy {
visibility: hidden;
}
完整的CSS按钮名称列表可以在以下链接中找到： Oracle CSS参考指南
