如果一列中有两个或更多贴纸，则不是您单击的每个贴纸都会响应它，显示带有按钮的 JToolBar

Question

我正在尝试编写看板。但是，如果一列中有两个或更多贴纸，通常只有当您第一次单击该列中的一个贴纸时，才会显示带按钮的 JToolBar。我还以为是坐标有问题，结果没找到。 StickerListener 响应事件，如果坐标正确，甚至打印“условие работает”，但 JToolBar 仍然不可见。

问题出在StickerListener.mouseClicked()的控制流程上：你搜索贴纸找到被点击的那个。

由于 if / else 你为每个没有被点击的标签重置了工具栏，这意味着你的代码只有在你点击最后一个标签时才有效（按迭代顺序） ).

如果您将代码从循环之前的 else 部分移动（以便它只执行一次），您的代码将起作用：

@Override
public void mouseClicked(MouseEvent e) {

    if(e.getButton() == MouseEvent.BUTTON1) {

        window.getStickerToolbar().setVisible(false);
        sew = null;
        window.stickerToolBarActivated = false;
        if (rd != null) {
            window.Read.removeActionListener(rd);
            rd = null;
        }
        if (del != null) {
            window.Delete.removeActionListener(del);
            del = null;
        }
        if (edit != null) {
            window.Edit.removeActionListener(edit);
            edit = null;
        }

        for (ProgressType pt : PTs) {
            for (Sticker s : pt.stickers) {
                System.out.println((e.getX() >= s.x) + " " + (e.getX() <= (s.x + s.width)) + " " +
                        (e.getY() - Y_DELTA >= s.y) + " " + (e.getY() - Y_DELTA <= (s.y + s.width)));
                System.out.println(e.getX() + " " + e.getY() + " " + s.x + " " + s.y);
                if (e.getX() >= s.x && e.getX() <= (s.x + s.width) &&
                        e.getY() - Y_DELTA >= s.y && e.getY() - Y_DELTA <= (s.y + s.width)) {
                    CurrentSticker = s;
                    JToolBar jtb = window.getStickerToolbar();
                    jtb.setVisible(true);
                    System.out.println("условие работает");
                    window.stickerToolBarActivated = true;
                    setListeners(s, pt, jtb);

                    //Sticker buf = (Sticker) CurrentSticker.clone();
                    //pt.addSticker(buf);
                    d.repaint();
                    return;
                }
            }
        }
    }

    System.out.println(e.getX()+" "+ e.getY()+" "+"cliicked");
}

如果一列中有两个或更多贴纸，则不是您单击的每个贴纸都会响应它，显示带有按钮的 JToolBar

If there are two and more stickers in one column, not every sticker you click responds to it, showing the JToolBar with buttons
