[英]How do I make A JPanel grid?
我正在嘗試為類似國際象棋的游戲創建一個 gui(6x6 棋盤,棋子較少)。
使用 for 循環和 JPanel 可以很容易地創建電路板,但我不知道如何將這些部件放在 JPanel 之上。 我嘗試通過創建一個帶有圖標的 JLabel 對象來添加一件並將其添加到 JPanel 中,但它看起來不太好。
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;
}
}
是否有我需要使用的特定類才能正確執行此操作? 默認板:
一塊板:
謝謝,
要獲得正確的電路板,只需處理顏色變化:
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);
}
}
嘗試將另一個組件(部件)添加到電路板(網格布局)會將其搞砸。
您想要做的是添加另一個包含這些片段的JPanel
。
JPanel
需要透明,所以它下面的板是可見的。 在擺動中實現它的一種方法是使用玻璃板:
import java.awt.Color;
import java.awt.Dimension;
import java.awt.GridLayout;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.ImageIcon;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingConstants;
public class Chess extends JFrame {
public Chess() {
setDefaultCloseOperation(EXIT_ON_CLOSE);
add( new BoardPanel()); //add underlaying board
setGlassPane(new PiecesPanel()); //add glass pane
getGlassPane().setVisible(true);
pack();
setVisible(true);
}
public static void main(String[] args) throws InterruptedException {
new Chess();
}
}
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;
//tiles color determined by odd/even
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;
}
}
}
}
//container for pieces
class PiecesPanel extends JPanel {
public static final int LENGTH = 6;
PiecesPanel(){
setOpaque(false); //make it transparent
setLayout(new GridLayout(LENGTH, LENGTH));
JComponent piece = new Piece();
add(piece);
}
}
class TileView extends JLabel {
public static final int SIZE = 100;
TileView(Color color) {
setPreferredSize(new Dimension(SIZE, SIZE));
setOpaque(true);
setBackground(color);
}
}
class Piece extends JLabel{
Piece() {
URL url = null;
try {
url = new URL("https://dl1.cbsistatic.com/i/r/2017/08/15/9b37ca73-de21-4998-ae7a-07d2915a551e/thumbnail/64x64/0cd91f1c045919af6bdafab3a6f07f99/imgingest-6339051052035379444.png");
} catch (MalformedURLException ex) { ex.printStackTrace(); }
setIcon(new ImageIcon(url));
setVerticalTextPosition(SwingConstants.BOTTOM);
setHorizontalTextPosition(SwingConstants.CENTER);
}
}
