JavaFX TextArea中的模糊文本

Question

我对JavaFX有一个奇怪的问题.我Scene在SceneBuilder中设计了一个简单的东西.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:

<?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application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,但我如何运行JDK 8显示正常文本

我把我的项目放在bitbucket上,如果有人试图查看代码或结账到你的机器,你可以自己看到这个

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.

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