进行GUI
时遇到了一个问题。我发布了一个截图,这样你就能更好地了解情况
起初,我只有一块我使用了GridLayout
的板
但是,我需要添加一个显示分数的面板,因此我放弃了GridLayout
,而选择了gridbagloayout
。我为分数正确定位了新的JPanel
,并在其中添加了2个JTextArea
,用于显示结果
问题是,每次一个玩家移动(因此棋盘会重新绘制以反映其新状态),文本区域就会闪烁,并被棋盘部分覆盖(见屏幕截图)。知道问题是什么吗?我已经设置了所有组件的首选大小,并尝试使用setOpaque
,但没有效果
主布局支架的代码

JTextArea的代码,保存结果:

/**
* {@value}

public static final String BACKGROUND_COLOR = "#066f02";
private static final int START_DISCS_NUMBER = 2;
private final Player player;
public ResultsTextView(final Player player) {
super();
setEditable(false);
setBackground(Color.decode(BACKGROUND_COLOR));
this.player = player;
setText(player.toString() + " result is: " + START_DISCS_NUMBER);
final Dimension dimension = new Dimension(100, 20);
setPreferredSize(dimension);
setMinimumSize(dimension);
setMaximumSize(dimension);
}
public void setDiscCount(final int discCount) {
setText(player.toString() + " result is:" + discCount);
}
}
添加一个得分面板让我想到一种模式,其中游戏板和得分都是听同一个游戏模型的视图。一个被引用的例子是,还有一个基于网格的游戏,可能会提供一些关于设计和布局的见解。特别是,在
BorderLayout.NORTH
中的RCStatus
视图和在BorderLayout.SOUTH
中的RCInfo
视图都可以收听RCModel
。游戏面板占据BorderLayout.CENTER
关于您提供的片段的一些注释:
- 让主视图扩展
,并将其添加到JPanel
实例中JFrame
- 不要试图用一个布局来解决所有问题
- 考虑
扩展到将MouseAdapter
实现MouseListener
- 重新考虑
SwingUtilities.invokeLater
更新GUI,这导致了闪烁。我开始使用它,现在一切都好了:)很多,但是如果没有你正在使用的代码,没有一个对你有用。编辑我的答案:)谢谢!为了更快地获得更好的帮助,发布一个。同意,将您的板面板与底部面板分开。让他们各自担任小组成员;使用GridLayout
板,并使用BorderLayout.CENTER
和BorderLayout.SOUTH
将底部面板的首选尺寸设置为新尺寸(0,首选高度)代码>@paranoidandroid:很好的观点;谢谢你的评论。引用的示例直接渲染网格;另一种选择是使用sGridLayout
按钮。谢谢!我开始使用BorderLayout,尽管问题在别处:)这是唯一确定的方法。
