有什么简单的方法可以让我的 jinternalframes 两全其美
- 当我希望它们充当 jdesktoppane 的一部分时嵌入
- 也可移动并能够处理自己的事件
希望这张图片能有所帮助。现在我有我的代码可以将项目拖到你的播放器并插入下一个可用的背包槽，但我也希望能够将它拖到任何背包槽，但正如你在下面看到的那样。有什么快速而肮脏的方法来解决这个问题吗？我的 JDesktopPane 顶部有一个面板，用于绘制所有内容（当然除了 jinternalframes 之外）。对不起所有的代码，没有 SSCCEE。只是觉得最好展示我的逻辑。
theDesktop.addMouseMotionListener(new MouseMotionListener() {
@Override
public void mouseDragged(MouseEvent e) {
updateMouseCursor(e);
if (MapGamePanel.draggingItem){
Point point = e.getPoint();
MapGamePanel.currentX = point.x;
MapGamePanel.currentY = point.y;
}
}
@Override
public void mouseMoved(MouseEvent e) {
updateMouseCursor(e);
}
});
theDesktop.addMouseListener(new MouseListener() {
@Override
public void mousePressed(MouseEvent e) {
if (e.getButton() == MouseEvent.BUTTON1){ //left
int whiteLeftSpace = (theDesktop.getWidth() - xTiles*32)/2;
boolean inGamePanel = e.getX() > whiteLeftSpace && e.getX() < (xTiles*32 + whiteLeftSpace) && e.getY() < yTiles*32;
String globalCoords = localToGlobalCoords((e.getX()-whiteLeftSpace)/32 + "," + e.getY()/32);
if (inGamePanel){
//looking for tiles with no mobs or players and loot
String[] globalCoordsSplit = globalCoords.split(",");
int globalX = Integer.parseInt(globalCoordsSplit[0]);
int globalY = Integer.parseInt(globalCoordsSplit[1]);
if ((!(globalX == characterX && globalY == characterY)) && //not under character

编辑由于这些建议，我与 JLayeredPane 混在一起。
public static JFrame frame;
public static JLayeredPane theDesktop;
public static MapGamePanel gamePanel; //where all my game tiles draw
....//lines removed
theDesktop = new JDesktopPane();
theDesktop.setOpaque(false);
theDesktop.add(backpackFrame, JLayeredPane.DEFAULT_LAYER);
theDesktop.add(gamePanel, JLayeredPane.DEFAULT_LAYER);
theDesktop.add(new JLabel("THIS SHOULD SHOW UP ABOVE THE OTHER CRAP, but does not"), JLayeredPane.DRAG_LAYER);
....//lots of lines removed
frame.getContentPane().add(theDesktop);
