Javafx 2 如何隐藏HTMLEditor的控件？
是否可以将HTMLEditor的控件隐藏在实际文本之上？（对齐、复制和粘贴图标、样式等）Javafx 2 如何隐藏HTMLEditor的控件？,javafx-2,Javafx 2,是否可以将HTMLEditor的控件隐藏在实际文本之上？（对齐、复制和粘贴图标、样式等） 感谢您的帮助根据官方教程，您似乎无法使用 在的实现中提供了格式工具栏 组成部分。不能切换它们的可见性。然而，你仍然可以 通过应用CSS样式自定义编辑器的外观 如果使用不支持的方法，则可以非常轻松地自定义工具栏 正如乌鲁克在回答中所说，以下方法没有得到官方支持 import java.util.regex.Pattern; import javafx.application.Application; impo
感谢您的帮助根据官方教程，您似乎无法使用 在的实现中提供了格式工具栏 组成部分。不能切换它们的可见性。然而，你仍然可以 通过应用CSS样式自定义编辑器的外观
如果使用不支持的方法，则可以非常轻松地自定义工具栏 正如乌鲁克在回答中所说，以下方法没有得到官方支持
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);
}
}
如果有人真的想用一种不受支持的方式隐藏工具栏，那么有一种更简单的方法来实现（我还没有测试过这是否会导致HtmleEditor控件出现任何问题，所以使用它的风险由您自己承担）

不透明度可以工作，但菜单保持活动状态。我已经制作了一些函数来修改HTML编辑器（以获得它的最低版本），也许其他人也会想使用它 守则：
