JavaFX Font

 

 

Definition of JavaFX Font

In JavaFX, font is a class that is used to denote fonts that renders the text available on screen. It is inherited from the object class.Font size is explained as mentioned in the points that are real-world measurementroughly 1/72 inch.Fonts are given to the text based on the user requirement and can be modified at any time. Some of the commonly used fonts include Verdana, Times new roman etc. In this article, we will see different aspects such as syntax, constructors, methods and examples of JavaFX font in the following sections.

Syntax of JavaFX Font

Below is the syntax of JavaFX font.

Font f = Font.font(FONT, FONT TYPE, SIZE);
  • Here, FONT denotes different fonts like verdana, times new roman etc.
  • FONT TYPE is bold, italics etc.
  • SIZE denotes the font size.

Constructors

Following are the two constructors of JavaFX font.

  • Font(double size): A font will be constructed with “system” as the default face.
  • Font(Stringname, double size): A font will be constructed with mentioned size and face name.

Methods

Let us see different methods of JavaFX font.

  • equals(Objectobj): This method denotes whether any of the other objects available is same as this.
  • font(double s): An appropriate font will be searched based on the font name and size that is default.
  • font(Stringf): An appropriate font will be searched based on the mentioned font name and size that is the default.
  • font(Stringf, double s): An appropriate font will be searched based on the mentioned font name and size.
  • font(Stringf, FontPosture p, double s): An appropriate font will be searched based on the mentioned family name, posture and size.
  • font(Stringf, FontWeight w, double s): An appropriate font will be searched based on the mentioned family name, weight and size.
  • font(Stringf, FontWeight w, FontPosture p, double s): An appropriate font will be searched based on the mentioned family name, weight, posture and size.
  • getDefault(): Default font will be retrieved that is from the “System” family, “Regular “style, and consistent size with the desktop environment of the user,to the limit that can be determined.
  • getFamilies(): All the families of font will be retrieved on the system of the user, including the SDK fonts as well as application fonts.
  • get family(): Family of font will be retrieved.
  • getFontNames(): All the names of font will be retrieved on the system of the user, including the SDK fonts as well as application fonts.
  • getFontNames(Stringfamily): All the names of font will be retrieved on the system of the user that is of the mentioned family, including the SDK fonts as well as application fonts.
  • getName(): Name of font will be retrieved.
  • getSize(): Size of font will be retrieved.
  • getStyle(): The font mentioned string explaining the style inside the font family.
  • hashCode(): Hash code will be retrieved for the font object.
  • loadFont(InputStreami, double s): A font resource will be loaded from the mentioned input stream.
  • loadFont(StringurlStr, double size): A font resource will be loaded from the mentioned URL.
  • toString(): Font object will be converted to a string representation.

Examples of JavaFX Font

Following are the examples are given below:

Example #1

Java Program that demonstrates the working of font class

Code:

import javafx.application.Application; 
import javafx.scene.Scene; 
import javafx.scene.control.*; 
import javafx.scene.layout.*; 
import javafx.stage.Stage; 
import javafx.scene.paint.*; 
import javafx.scene.text.*; 
import javafx.geometry.*; 
import javafx.scene.shape.*; 

//main class
public class FontSample extends Application { 

	// application launches here 
	public void start(Stage st) 
	{ 

		//exception handling
		try { 

			// stage title 
			st.setTitle(" Sample Font "); 

			//  TextFlow creation
			TextFlow tf = new TextFlow(); 

			// create text 
			Text txt = new Text("Sample \n"); 

			// color setting of the text 
			txt.setFill(Color.RED); 

			// FONT CREATION
			Font f = Font.font("Verdana", FontWeight.BOLD, 33); 

			// Text font setting 
			txt.setFont(f); 

			// text setting 
			tf.getChildren().add(txt); 

			//line space setting 
			tf.setLineSpacing(21.0f); 

			//  VBox creation
			VBox vb = new VBox(tf); 

			// svbox alignment setting
			vb.setAlignment(Pos.CENTER); 

			// scene creation 
			Scene sc = new Scene(vb, 400, 200); 

			// scene setting
			st.setScene(sc); 

			st.show(); 
		} 

		//catch exception
		catch (Exception ec) { 

			System.out.println(ec.getMessage()); 
		} 
	} 

	// Main Method 
	public static void main(String args[]) 
	{ 

		// application launches here
		launch(args); 
	} 
}

Output:

JavaFX Font-1.1

In this program, a text of font type verdana with red color and 33 font size is getting displayed on executing the code.

Example #2

Java Program that demonstrates font class with a drop box.

Code:

import javafx.application.Application; 
import javafx.scene.Scene; 
import javafx.scene.control.*; 
import javafx.scene.layout.*; 
import javafx.stage.Stage; 

import javafx.scene.paint.*; 
import javafx.scene.text.*; 
import javafx.geometry.*; 

import javafx.collections.*; 
import javafx.event.ActionEvent; 
import javafx.event.EventHandler; 

public class FontSample extends Application { 

	// application launches here 
	public void start(Stage st) 
{ 

try { 

	// stage title 
				st.setTitle(" Sample Font "); 

				//  TextFlow creation
				TextFlow tf = new TextFlow(); 

				// create text 
								Text txt = new Text("Sample \n"); 

				// color setting of the text 
				txt.setFill(Color.RED); 

				// FONT CREATION
				Font f = Font.font("Verdana", FontWeight.BOLD, 33); 


	//  names 
	String w[] = { "RED", "BLACK", "PINK", "LIGHT GREEN", 
						"YELLOW", "BLUE", "CYAN", "ORANGE", "VIOLET", 
						 }; 

    ComboBox cb = 
      new ComboBox(FXCollections.observableArrayList(w)); 
  
    

	// Create action event 
	EventHandler event = 
	new EventHandler() { 

		public void handle(ActionEvent e) 
		{ 

			// set font of the text 
			txt.setFont(Font.font((String)cb.getValue(), 
				FontWeight.valueOf((String)cb.getValue()), 20)); 
		} 
	}; 

	// Create action event 
	EventHandler event1 = 
	new EventHandler() { 

		public void handle(ActionEvent e) 
		{ 

			// set font of the text 
			txt.setFont(Font.font((String)cb.getValue(), 
				FontWeight.valueOf((String)cb.getValue()), 20)); 
		} 
	}; 

	// Set on action 
	cb.setOnAction(event); 

	// set font of the text 
	txt.setFont(f); 

	// set text 
	tf.getChildren().add(txt); 

	// set line spacing 
	tf.setLineSpacing(20.0f); 

	// create a HBox 
	HBox hbox = new HBox(cb); 

	// create VBox 
	VBox vbox = new VBox(hbox, tf); 

	// set spacing 
	vbox.setSpacing(30.0); 

	// set alignment of vbox 
	vbox.setAlignment(Pos.CENTER); 

	// create a scene 
	Scene sc = new Scene(vbox, 400, 300); 

	// set the scene 
	st.setScene(sc); 

	st.show(); 
} 

catch (Exception ev) { 

	System.out.println(ev.getMessage()); 
} 
} 

// Main Method 
public static void main(String args[]) 
{ 

	// launch the application 
	launch(args); 
} 
}

Output:

JavaFX Font-1.2

In this program also, a text of font type verdana with red color and 33 font size is getting displayed on executing the code. The difference is that a drop down is also displayed with certain colors as options.

JavaFX Font-1.3
