我正在制作游戏，但每当我运行第二个 jFrame 时，我必须调整它的大小以便为第二个 jFrame 获得正确的大小，有人知道为什么吗？
这是第一个 jFrame 类中打开第二个的方法：
private void playButtonMouseClicked(java.awt.event.MouseEvent evt) {
if (playerOneNameText.getText().equals(""))
{
}
if (playerTwoNameText.getText().equals(""))
{
}
else{
pOneName = playerOneNameText.getText();
pTwoName = playerTwoNameText.getText();
ChessBoardUI class1 = new ChessBoardUI(); // Creating object of Class1
class1.setVisible(true);
this.setVisible(false);
}
}
这是第二个 jFrame 类，我必须调整其大小才能正确定位：
package chess;
public class ChessBoardUI extends javax.swing.JFrame {
public ChessBoardUI() {
initComponents();
}
