JavaFX - Layout Panes Textflow


Advertisements

If we use this layout, you can set multiple text nodes in a single flow. The class named textFlow of the package javafx.scene.layout represents the text flow.

This class provides two properties, which are −

  • lineSpacing − This property is of double type and it is used to define the space between the text objects. You can set this property using the method named setLineSpacing().

  • textAlignment − This property represents the alignment of the text objects in the pane. You can set value to this property using the method setTextAlignment(). To this method you can pass four values: CENTER, JUSTIFY, LEFT, RIGHT.

Example

The following program is an example of the text flow layout. In this, we are creating three text objects with font 15 and with various colors. We are then adding them to a Text flow pane with an alignment value – Justify, while the line spacing is 15.

      //Retrieving the observable list of the TextFlow Pane 
      ObservableList list = textFlowPane.getChildren(); 
      
      //Adding cylinder to the pane  
      list.addAll(text1, text2, text3, text4);

      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); 
   } 
}

Compile and execute the saved java file from the command prompt using the following commands.
