JavaFX TextArea中的模糊文本 [英] Blurred text in JavaFX TextArea

问题描述

我对JavaFX有一个奇怪的问题。我在SceneBuilder中设计了一个简单的 Scene 。文本在预览中看起来没问题，但在运行应用程序时文本看起来模糊，请考虑以下图像。

这是 FXML ：

I am having a weird issue with JavaFX. I designed a simple Scene in SceneBuilder. The text looks ok in a preview, but in the running the app the text looks blurred, consider the following image. Here is the FXML:

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>

<AnchorPane id="AnchorPane" fx:id="root" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="br.mviccari.javafxtest.controllers.TelaMensagemController">
  <children>
    <TitledPane alignment="CENTER_LEFT" animated="false" collapsible="false" contentDisplay="LEFT" prefHeight="400.0" prefWidth="600.0" text="Janela legal" textAlignment="LEFT" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
      <content>
        <AnchorPane id="Content" minHeight="0.0" minWidth="0.0" prefHeight="180.0" prefWidth="200.0">
          <children>
            <HBox id="HBox" alignment="CENTER" spacing="5.0" AnchorPane.bottomAnchor="14.0" AnchorPane.rightAnchor="14.0">
              <children>
                <Button mnemonicParsing="false" onAction="#acaoFodase" prefHeight="53.9609375" prefWidth="128.0" text="Foda-se" />
                <Button mnemonicParsing="false" onAction="#acaoOk" prefHeight="53.9609375" prefWidth="128.0" text="OK" />
              </children>
            </HBox>
            <TextArea fx:id="campoTexto" disable="false" editable="true" focusTraversable="true" prefHeight="278.0" prefWidth="570.0" rotate="0.0" text="Aqui vai um texto padrão motherfucker!" wrapText="true" AnchorPane.bottomAnchor="82.0" AnchorPane.leftAnchor="14.0" AnchorPane.rightAnchor="12.0" AnchorPane.topAnchor="14.0" />
          </children>
        </AnchorPane>
      </content>
    </TitledPane>
  </children>
</AnchorPane>

这是应用程序类代码：

FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/br/mviccari/javafxtest/layouts/telaMensagem.fxml"));
Parent root = fxmlLoader.load();
TelaMensagemController controller = fxmlLoader.getController();
controller.setParametroDeTeste("PIKACHU EU ESCOLHO VC!");
controller.init();
Stage stage = new Stage(StageStyle.DECORATED);
stage.initModality(Modality.WINDOW_MODAL);
stage.initOwner(labelStatus.getScene().getWindow());
stage.setOpacity(1);
stage.setTitle("My New Stage Title");
stage.setScene(new Scene(root, 450, 450));
stage.showAndWait();

我试图使用JDK 7运行应用程序，这样文本不再模糊，但是如何运行JDK 8显示正常文本

I have tried to run the app using JDK 7, this way the text is not blurred anymore, but how can I run it with JDK 8 showing a normal text

我已将项目放在bitbucket上，如果有人试图查看代码或结账到你的机器，你可以自己看看

I have put my project on bitbucket, if anyone tries to see the code or checkout to your machine, you can see this on your own

推荐答案

我已经找到了解决这个问题的方法。我能够确定问题集中在JavaFX 8中引入的错误，当ScrollPane具有十进制值约束时，导致ScrollPane中显示的内容有些模糊，该错误与内容的缓存图像有关关闭缓存工作。 TextAreas使用ScrollPanes。

I have figured out a solution for this issue. I was able to ascertain that the issue is centered around a bug introduced in JavaFX 8 which causes some blurriness of the content displayed within a ScrollPane when said ScrollPane has decimal value constraints, the bug has to do with the cached image of the content so turning off caching works. TextAreas make use of ScrollPanes.

textArea.setCache(false);
ScrollPane sp = (ScrollPane)textArea.getChildrenUnmodifiable().get(0);
sp.setCache(false);
for (Node n : sp.getChildrenUnmodifiable()) {
    n.setCache(false);
}
