JCheckBoxを選択した後にイベントを作成し、グラフィックフレームをGUIフレームに出力します。

Question

最初にテキストフィールド、名前提出ボタン、送信ボタン、目、鼻、口のチェックボックスを含むフレームを含めます。ボタンをクリックすると、送信された名前を顔の下に表示して、顔を表示します。目と鼻だけがチェックされている場合は、それぞれのサイズを設定し、それらの機能を表すコンポーネントを描画します。

こんにちは、私は、GUIにかなり新しいですし、これは私がこれまで持っているものです。私が問題を抱えているのは、自分のチェックボックスにイベントリスナーを接続して作成することができることです。そして、一旦私が提示したヒットを送信すると、そこにはスマイリーフェイスが作成されます。これは私が顔のグラフィックスクラスのために持っているものです。私は10月27日の時点で、私のものを頭に関係なくの画像を描画するためにボタンを提出し、どちらかの目、鼻、口、またはすべてなど

Answer 1

、あなたが名前を必要とし、目、鼻および/または口を描画するかどうか。これらのパラメータで構築できるFaceGraphic用の別のクラスを作成します。 drawStringメソッドを使用すると、グラフィックに名前を追加できます。例えば

：

import java.awt.Color; 
import java.awt.Graphics; 
import javax.swing.JPanel; 

public class FaceGraphic extends JPanel { 
    private String name; 
    private boolean hasEyes; 
    private boolean hasNose; 
    private boolean hasMouth; 

    public FaceGraphic(String name, boolean hasEyes, boolean hasNose, boolean hasMouth) { 
     setParameters(name, hasEyes, hasNose, hasMouth); 
    } 

    public void setParameters(String name, boolean hasEyes, boolean hasNose, boolean hasMouth) { 
     this.name = name; 
     this.hasEyes = hasEyes; 
     this.hasNose = hasNose; 
     this.hasMouth = hasMouth; 
    } 

    @Override 
    protected void paintComponent(Graphics graphics) { 
     super.paintComponent(graphics); 

     graphics.setColor(Color.yellow); 

     // head 
     graphics.fillOval(100, 100, 100, 100); 

     graphics.setColor(Color.black); 

     // name 
     graphics.drawString(name, 150, 50); 

     if (hasEyes) { 
      // left eye 
      graphics.fillOval(120, 125, 20, 20); 
      // right eye 
      graphics.fillOval(160, 125, 20, 20); 
     } 

     if (hasNose) 
      // nose 
      graphics.drawLine(150, 165, 150, 150); 

     if (hasMouth) 
      // mouth 
      graphics.drawArc(120, 130, 60, 60, 0, -180); 
    } 
} 

編集：あなたが送信ボタンのイベントハンドラでsetParametersメソッドへの呼び出しを追加することができsetParameters

を呼び出す例：

JButton btnSubmit = new JButton("Submit"); 
btnSubmit.setBounds(220, 75, 90, 27); 
btnSubmit.addActionListener(new ActionListener() { 

    // Handle events that are generated by buttons, meets 
    // Requirement 5.3 
    public void actionPerformed(ActionEvent event) { 
     // print name to niceFace label from textField once user inputs and hits submit 
     String name = textField.getText(); 
     lblNiceFace.setText("Nice face " + name + "!"); 

     component.setParameters(name, chckbxEyes.isSelected(), 
            chckbxNose.isSelected(), chckbxMouth.isSelected()); 
     component.repaint(); 
    } 
});
