JPanel以额外宽度绘制

我在JPanel上画了一张Stratego棋盘,用来设置玩家的棋子。在玩家正确安排这些面板的两个不同实例后,主板(具有相同的格式和布局,将具有不同的外观和逻辑行为)将显示。

我的问题是第二个输入面板和主板(目前没有任何功能或部件)是SOMETIMES设置的底部和右侧有额外的宽度,导致10x10网格不占用整个像它应该的板空间。

播放器1的初始输入面板似乎工作正常,从未出现过此问题。第二个面板和主面板只有SOMETIMES有这个问题,所以我不完全确定它源于何处。

这是设置面板和内容的主要方法。

public class Core {

    public static void main(String[] args) {

        LogicInterpreter logic = new LogicInterpreter();

        Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();

        InputFrame inputPlayer1 = new InputFrame(logic, 1, "red", 600, 600);
        inputPlayer1.setLocation(dim.width / 2 - inputPlayer1.getSize().width/2,
            dim.height / 2 - inputPlayer1.getSize().height / 2);

        while(!logic.isSetUp1()){
            //Just to make it work
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

        //Now bring up board 2

        InputFrame inputPlayer2 = new InputFrame(logic, 2, "blue", 600, 600);
        inputPlayer2.setLocation(dim.width / 2 - inputPlayer2.getSize().width/2,
                dim.height / 2 - inputPlayer2.getSize().height / 2);

        while(!logic.isSetUp2()){
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        openBoards(logic);
    }

    public static void openBoards(LogicInterpreter logic) {
        try {
            Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
            MainBoard board = new MainBoard(logic);
            board.setLocation(dim.width / 2 - board.getSize().width / 2, dim.height / 2 - board.getSize().height / 2);
        } catch (Exception e) {
            System.exit(1);
        }
    }
}

此外,这是输入面板内的代码。我不确定什么是相关的,所以我不能拿出东西。抱歉。我将保留主板设置代码,因为它实际上是相同的。

答案 0 :(得分:1)

您是否检查了“有时”添加了多少像素?

当我在我的jframe上调用setResizable(true)时,我注意到“有时”宽度和高度都比我预期的多10个像素。

如果是这种情况,我回答了类似的问题here。 我能够使用'技巧'解决问题,多次调用包。

在答案中我还链接了另一个类似的问题(this one),我无法找到另一个解决方案,但有些用户描述了这个错误。
