Question

我试过搜索但找不到答案。我将不胜感激任何帮助。

在Eclipse.Version：Luna Service Release 1（4.4.1）中编辑2+窗口时出现此错误。例如，打开2级窗口。

点击一个面板以激活class A。如果我点击Class B使Class A显示活动面板，则会收到相同的错误。

解决方法是关闭所以我只有一个面板显示用于编辑我的类。

我也得到：

Warning: The environment variable HOME is not set. The following directory will be used     to store the Git
user global configuration and to define the default location to store repositories:     'C:\Users\Chris'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.

但我试图在Eclipse中安装Git无济于事。

提前谢谢你，克里斯

Answer 1

我在Fedora 25 / Eclipse Neon.3上遇到了同样的问题。经过大量的搜索，我找到了this Eclipse bug。任何Fedora / Linux用户遇到同样问题的解决方法是在启动Eclipse之前运行以下命令：

export SWT_WEBKIT2=1
export SWT_GTK3=0
./eclipse

Answer 2

在我的案例中解决了这个问题的是Windows更新。

Answer 3

对我来说，通过关闭＆＃34; nVidia桌面管理器＆＃34;来解决这个问题。

其他人通过关闭其他桌面管理器应用来修复此问题，例如＆＃34; DisplayFussion＆＃34;。

Answer 4

在大多数情况下，原因是没有处理某些资源（控件，图像，字体......）。

但是，例如为了创建控件，当OS.CreateWindowEx（）返回0时，抛出异常（您可以参考https://msdn.microsoft.com/ru-ru/library/windows/desktop/ms632680(v=vs.85).aspx获取更多详细信息）

（这当然只涉及SWT的Windows impl）

您可以使用免费的Sysinternal Process Explorer来检查您是否实际占用过多句柄（在Process Explorer中，选择View＆gt; Select Columns ...＆gt; Process Memory选项卡＆gt;检查“USER Objects”）
可能的原因可能是将无效的父级传递给控件的构造函数

希望这有帮助
