Y!
我想用jTable创建一个TabbedPane。
设计师:
JForm中的构造函数代码:
initComponents();
this.add(jTabbedPane1);
jTabbedPane1.addTab("Test", jPanel1);
jPanel1.add(jTable1);
自动生成代码:
private void initComponents() {
jTabbedPane1 = new javax.swing.JTabbedPane();
jPanel1 = new javax.swing.JPanel();
jScrollPane1 = new javax.swing.JScrollPane();
jTable1 = new javax.swing.JTable();
jButton_add = new javax.swing.JButton();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
jPanel1.setMinimumSize(new java.awt.Dimension(550, 300));
jTable1.setModel(new javax.swing.table.DefaultTableModel(
new Object [][] {
{"dddsds", null, null, null},
{null, null, null, null},
{null, null, null, null},
{null, null, null, null}
},
new String [] {
"Title 1", "Title 2", "Title 3", "Title 4"
}
));
jScrollPane1.setViewportView(jTable1);
javax.swing.GroupLayout jPanel1Layout = new javax.swing.GroupLayout(jPanel1);
jPanel1.setLayout(jPanel1Layout);
jPanel1Layout.setHorizontalGroup(
jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(jPanel1Layout.createSequentialGroup()
.addContainerGap()
.addComponent(jScrollPane1, javax.swing.GroupLayout.DEFAULT_SIZE, 530, Short.MAX_VALUE)
.addContainerGap())
);
jPanel1Layout.setVerticalGroup(
jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(jPanel1Layout.createSequentialGroup()
.addContainerGap()
.addComponent(jScrollPane1, javax.swing.GroupLayout.PREFERRED_SIZE, 287, javax.swing.GroupLayout.PREFERRED_SIZE)
.addContainerGap(27, Short.MAX_VALUE))
);
jButton_add.setText("add");
jButton_add.setVerticalTextPosition(javax.swing.SwingConstants.BOTTOM);
jButton_add.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jButton_addActionPerformed(evt);
}
});
javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(javax.swing.GroupLayout.Alignment.TRAILING, layout.createSequentialGroup()
.addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.TRAILING)
.addGroup(javax.swing.GroupLayout.Alignment.LEADING, layout.createSequentialGroup()
.addGap(39, 39, 39)
.addComponent(jPanel1, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
.addGroup(layout.createSequentialGroup()
.addContainerGap()
.addComponent(jTabbedPane1, javax.swing.GroupLayout.DEFAULT_SIZE, 579, Short.MAX_VALUE))
.addGroup(javax.swing.GroupLayout.Alignment.LEADING, layout.createSequentialGroup()
.addGap(31, 31, 31)
.addComponent(jButton_add)))
.addContainerGap())
);
layout.setVerticalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(layout.createSequentialGroup()
.addContainerGap()
.addComponent(jTabbedPane1, javax.swing.GroupLayout.PREFERRED_SIZE, 22, javax.swing.GroupLayout.PREFERRED_SIZE)
.addGap(28, 28, 28)
.addComponent(jPanel1, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
.addGap(18, 18, 18)
.addComponent(jButton_add)
.addContainerGap(javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
);
pack();
}// </editor-fold>
问题:
jTable1是不可见的,并且按钮在jTabbedPane下而不在jPanel下。
请帮忙
最佳答案
您不应将jTable1
两次添加到jPanel1
。 initComponents()
已经通过使用jScrollPane1
将jTable1
(包括jPanel1
)添加到jPanel1Layout
。但是在构造函数中,您需要第二次添加jTable1
,显式地添加到jPanel1
。因此,您的构造函数应如下所示:
initComponents();
this.add(jTabbedPane1);
jTabbedPane1.addTab("Test", jPanel1);
请注意,我已删除了
jPanel1.add(jTable1);
行然后,jTabbedPane1会遇到相同的问题,该问题被两次添加到内容窗格中。
从生成的代码中,我可以说您可能对Netbeans GUI设计器进行了一些错误的操作,因为
jTable1
不在jTabbedPane1
内,而是直接在框架的内容窗格内。我想您应该从头开始重新设计面板,或者至少在设计器中修改UI。需要理解的重要一点是,当您使用
GroupLayout
API时,组件会自动添加到其容器中,因此不应专门添加。实际上,我最好的建议是:不要使用NetBeands UI设计器并手动编写UI(但不能使用
GroupLayout
编写,因为太复杂了,无法手动编码)。
