Question

我很抱歉没有提供太多信息;我是Java的新手。请问您能帮我解决这个问题吗？我想将标签和文本字段旁边的一个和所有按钮对齐。我怎么能这样做？

以下是我创建GroupLayout的方法：

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);

以下是我创建水平组的方法：

layout.setHorizontalGroup(

  layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)

  .addComponent(jPanel1, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)

  .addGroup(layout.createParallelGroup()

  .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.TRAILING)

  .addGroup(layout.createSequentialGroup()

  .addComponent(jScrollPane1, javax.swing.GroupLayout.PREFERRED_SIZE, 400, javax.swing.GroupLayout.PREFERRED_SIZE))

  .addGroup(layout.createParallelGroup()
    .addGap(40, 40, 40)
    .addComponent(jLabel2)
    .addComponent(txtitem, javax.swing.GroupLayout.PREFERRED_SIZE, 100, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel3)
    .addComponent(txtprice, javax.swing.GroupLayout.DEFAULT_SIZE, 100,javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel4) 
    .addComponent(txtquantity, javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel5)
    .addComponent(txtreorder, javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btnupdate)//,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)//,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(btndelete,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(btnload,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(btnadd)//,javax.swing.GroupLayout.DEFAULT_SIZE, 100, javax.swing.GroupLayout.DEFAULT_SIZE)
    .addComponent(txtreorder)
    .addComponent(jLabel5))
    )
  )
);

以下是我创建VerticalGroup的方法：

layout.setVerticalGroup(
  layout.createParallelGroup()
    .addGroup(layout.createSequentialGroup()
    .addComponent(jPanel1, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addGap(40, 40, 40)
    .addGroup(layout.createSequentialGroup()
    .addComponent(jLabel2)
    .addComponent(txtitem, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel3)
    .addComponent(txtprice, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel4)
    .addComponent(txtquantity, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(jLabel5)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    // .addComponent(btnadd))
    .addGap(40, 40, 40)
    .addComponent(btnadd,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btnupdate,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btndelete,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(btnload,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addComponent(txtreorder, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
    .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
    .addComponent(jScrollPane1, javax.swing.GroupLayout.DEFAULT_SIZE, 200, Short.MAX_VALUE)
    .addContainerGap()
    )

Answer 1

您永远不会被迫为所有组件使用单个面板。

我想将标签和文本字段旁边的对齐

也许使用一个包含八个SpringLayout或GridBagLayout的面板。阅读How to Use Layout Managers上Swing教程中的部分，了解更多信息和示例。

和单行中的所有按钮。

也许使用带FlowLayout的面板。

然后将第一个面板添加到对话框的CENTER，将按钮面板添加到SOUTH。

Answer 2

这样的事情：

label1.setBounds(2,2,50,25); 
textField1.setBounds(10,2,50,25);

ETC ...对于您想要以编程方式放置的每个项目。

您需要使用（x，y，w，h）坐标来满足您的需求。

我想将标签和文本字段彼此对齐，并将所有按钮对齐在一行中;我该怎么做？
