JavaFX - 佈局窗格 TextFlow



如果我們使用此佈局,則可以在單個流中設定多個文字節點。名為textFlowjavafx.scene.layout包中的類表示文字流。

此類提供兩個屬性,它們是:

  • lineSpacing - 此屬性為雙精度型別,用於定義文字物件之間的空間。可以使用名為setLineSpacing()的方法設定此屬性。

  • textAlignment - 此屬性表示窗格中文字物件的對齊方式。可以使用setTextAlignment()方法為此屬性設定值。在此方法中,您可以傳遞四個值:CENTER、JUSTIFY、LEFT、RIGHT。

示例

以下程式是文字流佈局的示例。在此,我們建立了三個字型為 15 且顏色不同的文字物件。然後,我們將它們新增到 TextFlow 窗格中,對齊方式為 Justify,行間距為 15

將此程式碼儲存在名為TextFlowExample.java的檔案中。

      Text text1 = new Text("Welcome to Tutorialspoint "); 
      
      //Setting font to the text 
      text1.setFont(new Font(15));

      text3.setFont(new Font(15)); 
      
      //Setting color to the text 
      text3.setFill(Color.DARKGRAY); 
       
      Text text4 = new Text("We believe in easy learning"); 
      
      //Setting font to the text 
      text4.setFont(new Font(15)); 
      text4.setFill(Color.MEDIUMVIOLETRED); 
       
      //Creating the text flow plane 
      TextFlow textFlowPane = new TextFlow(); 
       
      //Setting the line spacing between the text objects 
      textFlowPane.setTextAlignment(TextAlignment.JUSTIFY); 
       
      //Setting the width  
      textFlowPane.setPrefSize(600, 300); 
       
      //Setting the line spacing  
      textFlowPane.setLineSpacing(5.0); 
       
      //Retrieving the observable list of the TextFlow Pane 
      ObservableList list = textFlowPane.getChildren(); 
      
      //Adding cylinder to the pane  
      list.addAll(text1, text2, text3, text4);        
         
      //Creating a scene object 
      Scene scene = new Scene(textFlowPane);  
      
      //Setting title to the Stage 
      stage.setTitle("text Flow Pane Example");
      
      //Adding scene to the stage 
      stage.setScene(scene); 
         
      //Displaying the contents of the stage 
      stage.show();         
   } 
   public static void main(String args[]){ 
      launch(args); 
   } 
}

使用以下命令從命令提示符編譯並執行儲存的 java 檔案。

javac TextFlowExample.java 
java TextflowExample

執行上述程式後,將生成如下所示的 JavaFX 視窗。
