当我将布局设置为GridBagLayout
时,我遇到了一个错误,但它以前工作得很好。
import javax.swing.*;
import java.awt.*;
public class GridBagLayoutTest {
public static void main (String [] args)
{
JFrame frame = new JFrame();
frame.setLayout(new GridBagLayout());
}
}
我得到一个错误说:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method setLayout(LayoutManager) in the type JFrame is not applicable for the arguments (GridBagLayout)
您必须导入java.awt包,因为GridBagLayout类属于该包。
