我有这个带有按钮的JFrame 我添加了ActionPerformed的添加工作,就像它所使用的那样 但我的一个按钮执行一个长代码,我想将它移动到一个单独的类,然后将其导入AP()。
有可能吗? (含义按钮名称,JButton东西......)。
public class Frame扩展JFrame {
/* -------------------------------------------------------------------- */
public JButton News;
public boolean TP_B = false,
MC_B = false;
public JEditorPane TechPack_JEP,
Minecraft_JEP;
public JScrollPane TechPack_JSP,
Minecraft_JSP;
public void News_Button(){
Icon News_img = new ImageIcon(this.getClass().getResource("/onglet/News.png"));
Icon News_select_img = new ImageIcon(this.getClass().getResource("/onglet/News_Select.png"));
News = new JButton(News_img);
News.setRolloverIcon(News_select_img);
News.setOpaque(false);
News.setContentAreaFilled(false);
News.setBorderPainted(false);
News.setFocusPainted(false);
Insets insets_1 = News.getInsets();
Dimension size_1 = News.getPreferredSize();
News.setBounds(-34 + insets_1.left, -10 + insets_1.top, size_1.width, size_1.height); // Do not complain about the setbounds (I use it for a specefic reason)
add(News);
News.addActionListener(this);
}
public void TP_Button(){
Icon TP_img = new ImageIcon(this.getClass().getResource("/onglet/TP.png"));
Icon TP_Select_img = new ImageIcon(this.getClass().getResource("/onglet/TP_Select.png"));
TP = new JButton(TP_img);
TP.setRolloverIcon(TP_Select_img);
TP.setOpaque(false);
TP.setContentAreaFilled(false);
TP.setBorderPainted(false);
TP.setFocusPainted(false);
Insets insets_6 = TP.getInsets();
Dimension size_6 = TP.getPreferredSize();
TP.setBounds(50+ insets_6.left, -10 + insets_6.top, size_6.width, size_6.height);
add(TP);
TP.setVisible(false);
TP.addActionListener(this);
}
public void MC_Button(){
Icon MC_img = new ImageIcon(this.getClass().getResource("/onglet/MC.png"));
Icon MC_select_img = new ImageIcon(this.getClass().getResource("/onglet/MC_Select.png"));
MC = new JButton(MC_img);
MC.setRolloverIcon(MC_select_img);
MC.setOpaque(false);
MC.setContentAreaFilled(false);
MC.setBorderPainted(false);
MC.setFocusPainted(false);
Insets insets_7 = MC.getInsets();
Dimension size_7 = MC.getPreferredSize();
MC.setBounds(148+ insets_7.left, -10 + insets_7.top, size_7.width, size_7.height);
add(MC);
MC.setVisible(false);
MC.addActionListener(this);
}
public Frame(){
super("Multi Launcheur");
setLayout(null);
News_Button();
TP_Button();
MC_Button();
}
public void actionPerformed(ActionEvent e){
if(e.getSource() == TP){
System.out.println("TP");
TP_B = true;
if(MC_B == true){
Minecraft_JSP.setVisible(false);
}
TechPack_JEP = new JEditorPane();
TechPack_JEP.setEditable(false);
TechPack_JEP.setBorder(null);
try {
TechPack_JEP.setPage("http://www.techpackcreator.tumblr.com/");
} catch (IOException error) {
TechPack_JEP.setContentType("text/html");
System.out.println("ERROR");
}
TechPack_JSP = new JScrollPane(TechPack_JEP);
TechPack_JSP.setBounds(67, 27, 798, 465);
TechPack_JSP.getVerticalScrollBar().setUnitIncrement(10);
add(TechPack_JSP);
}
if(e.getSource() == MC){
System.out.println("MC");
MC_B = true;
if(TP_B == true){
TechPack_JSP.setVisible(false);
}
Minecraft_JEP = new JEditorPane();
Minecraft_JEP.setEditable(false);
Minecraft_JEP.setBorder(null);
try {
Minecraft_JEP.setPage("http://www.mcupdate.tumblr.com/");
} catch (IOException error) {
Minecraft_JEP.setContentType("text/html");
}
Minecraft_JSP = new JScrollPane(Minecraft_JEP);
Minecraft_JSP.setBounds(67, 27, 798, 465);
Minecraft_JSP.getVerticalScrollBar().setUnitIncrement(10);
add(Minecraft_JSP);
}
}
好的,这就是Frame类(我只留下相关按钮的代码)。
当“新闻”按钮显示这些TP和MC按钮时。
当点击其中一个时,它会显示新闻(此处为TechPack:我的服务器或Minecraft新闻)
我想要的是if(e.getSource() == TP)
中的所有代码都在一个单独的类中(称为News_TechPack)

请记住,我使用的是Main类而不是Frame类。你也可以使用你的。另外,请考虑不将您的行为写入单独的类,而只是写入Frame类中的函数。在这个例子中,您应该能够自己编写函数。
public class Main implements ActionListener{
JFrame f;
JButton button;
boolean TP_B = false;
ButtonBehaviour bb;
public Main()
{
bb = new ButtonBehaviour(this);
f = new JFrame();
f.setSize(400,400);
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
button = new JButton("Test");
button.addActionListener(this);
f.add(button);
f.setVisible(true);
}
public static void main(String[] args) throws IOException {
new Main();
}
@Override
public void actionPerformed(ActionEvent e) {
if(e.getSource() == button)
{
System.out.println("Call the specific function in your behaviour class");
bb.buttonBehaviour();
}
}
}
class ButtonBehaviour{
Main m;
public ButtonBehaviour(Main pMain)
{
m = pMain;
}
public void buttonBehaviour()
{
System.out.println("TP");
m.TP_B = true;
//Write here your rest behaviour.
//Keep in mind to use your Main instance or Frame instance
//for calling and changing your specific variables.
//you could also just create your
//buttonBehaviour-Functions in your Frame class. Would
//be easier
}
}

如果您的意思是“导入”作为一种自动“复制和粘贴”,我认为您可以(也许您的IDE允许它,但它是自定义IDE功能,而不是语言功能)。 而是重构代码:将长代码移动到新类(或方法)并传递所有必需参数(至少JFrame作为唯一参数)。 作为解决方案有点微不足道,但可以工作。
