请教前辈们指点DELPHI的学习。
1、直接学Delphi没有问题,就像有的燕窝溯源码如何看人直接学VC一样。但我个人建议先学一下Delphi的条件选择like源码母语Object Pascal(Delphi不是语言,是编程工具),因为即使你会拖拉控件弄出一个界面,但你迟早有一天还会面临基本的语法问题。网上有些书是介绍Object Pascal的,如Object Pascal 参考手册、Pascal精要等等。
2、每日一坎源码我是个Delphi业余爱好者,原来有较好的Pascal基础。第一次接触Delphi,用了很短时间大概就摸清了控件之类的java如何阅读源码玩意。后来才发现,控件不过是初学者摆弄摆弄的玩意,真正深入VCL需要掌握Object Pascal的基本语法和理念。
3、php zip压缩源码至于入门书籍,可以看看台 湾 陈宽达的《Delphi深度历险》,谭浩强的《PASCAL语言程序设计》。大陆作者的书不要买,大部分是互相抄的,或者从人家BBS上摘录下来的,水平很低。这年月,狗都能出书。另外有时间可以看看Delphi自带的源码,很有好处。
JAVA将一个JFrame放入另一个JFrame
1.先下载一个windowbuilder,安装到Eclipse中,就可以很容易做出来图形化的界面设计
源代码如下:
第一个Java文件Menu.java
package output;
import java.awt.BorderLayout;
public class Menu extends JFrame {
private JPanel contentPane;
/
*** Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Menu frame = new Menu();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/
*** Create the frame.
*/
public Menu() {
setTitle("\u7B2C\u4E\u4E2AJFrame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(, , , );
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
setContentPane(contentPane);
JDesktopPane desktopPane = new JDesktopPane();
desktopPane.setBackground(Color.ORANGE);
contentPane.add(desktopPane, BorderLayout.CENTER);
JButton btnframe = new JButton("\u7B2C\u4E8C\u4E2AJFrame");
btnframe.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
One frame = new One();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
});
btnframe.setBounds(, , , );
desktopPane.add(btnframe);
JButton btnjframe = new JButton("\u7B2C\u4E\u4E2AJFrame");
btnjframe.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Two frame = new Two();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
});
btnjframe.setBounds(, , , );
desktopPane.add(btnjframe);
}
}
第二个文件One.java
package output;
import java.awt.BorderLayout;
public class One extends JFrame {
private JPanel contentPane;
/
*** Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
One frame = new One();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/
*** Create the frame.
*/
public One() {
setTitle("\u7B2C\u4E8C\u4E2AJFrame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(, , , );
contentPane = new JPanel();
contentPane.setBackground(Color.GREEN);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
setContentPane(contentPane);
}
}
第三个Java文件
package output;
import java.awt.BorderLayout;
public class Two extends JFrame {
private JPanel contentPane;
/
*** Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Two frame = new Two();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/
*** Create the frame.
*/
public Two() {
setTitle("\u7B2C\u4E\u4E2AJFrame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(, , , );
contentPane = new JPanel();
contentPane.setBackground(Color.BLUE);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
setContentPane(contentPane);
}
}
