我正在尝试为象棋游戏(较少的6x6棋盘)创建gui。
使用循环和JPanels创建板非常容易,但是我不知道如何将这些块放在JPanel之上。我尝试通过创建带有图标的JLabel对象来添加一个片段并将其添加到JPanel中,但是看起来不太好。
public class BoardPanel extends JPanel
{
public static final int LENGTH = 6;
private final Color[] COLOR_ARRAY = {Color.decode("#FFFACD"), Color.decode("#593E1A")};
public BoardPanel()
{
//grid layout 6x6
setLayout(new GridLayout(LENGTH, LENGTH));
int numView = 0;
//tiles color determined by odd/even
for (int i = 0; i < LENGTH; i++)
{
for (int j = 0; j < LENGTH; j++)
{
add(new TileView(numView, COLOR_ARRAY[j % 2]));
}
swap();
}
}
private void swap() {
Color temp = COLOR_ARRAY[0];
COLOR_ARRAY[0] = COLOR_ARRAY[1];
COLOR_ARRAY[1] = temp;
}
}
是否需要使用特定的类才能正确执行此操作? 默认面板:

答案 0 :(得分:1)
要使电路板正确,只需处理颜色变化:
class BoardPanel extends JPanel
{
public static final int LENGTH = 6;
private final Color[] COLOR_ARRAY = {Color.decode("#FFFACD"), Color.decode("#593E1A")};
public BoardPanel() {
//grid layout 6x6
setLayout(new GridLayout(LENGTH, LENGTH));
int numView = 1;
for (int i = 0; i < LENGTH; i++)
{
numView = (numView == 0) ? 1:0;
for (int j = 0; j < LENGTH; j++)
{
add(new TileView(COLOR_ARRAY[numView]));
numView = (numView == 0) ? 1:0;
}
}
}
}
class TileView extends JLabel {
TileView(Color color) {
setPreferredSize(new Dimension(100,100));
setOpaque(true);
setBackground(color);
}
}
尝试将另一个组件(一块)添加到板上(网格布局)会使其混乱。
您要做的是添加另一个包含碎片的JPanel
。
