在GridBagLayout中链接2个单元格

Question

我想在GridBagLayout中链接2个单元格。 我使用Netbeans，所以我用JAppletForm编写。

JTextField dodawanyTextField = new javax.swing.JTextField();

dodawanyTextField.setText(nazwaLekcjiTextField.getText());

gridBagConstraints = new java.awt.GridBagConstraints();
gridBagConstraints.gridwidth = 2;
gridBagConstraints.gridx = 2;
gridBagConstraints.gridy = 2;

jPanel3.add(dodawanyTextField, gridBagConstraints);

但它没有用。

Answer 1

调整您的GridBagConstraint's weightx和fill，使组件沿x轴展开：

gridBagConstraints.weightx = 1;
gridBagConstraints.fill = GridBagConstraints.HORIZONTAL;
