如何解决＆＃34;不再处理异常＆＃34;，Eclipse Oxygen，Windowbuilder Pro

标签： java linux eclipse swing windowbuilder

我在Debian Buster下使用Eclipse Oxygen和WindowBuilder Pro，当我想在设计选项卡中打开一个.java文件（带有Swing JFrame）时，我得到一个＆＃34;设计师，没有更多句柄＆＃34; -错误。之后，我被问到是否要退出工作台，因为可能会发生更多SWT错误，并且可能会意外关闭。

点击否后，我仍然可以看到设计师，但是它对尝试改变JFrame的任何点击或动作都没有反应。

2 个答案:

答案 0 :(得分：3)

在命令行中键入：

daniel @ DanielPC：〜/ eclipse / jee-oxygen / eclipse $ 导出SWT_GTK3 = 0 daniel @ DanielPC：〜/ eclipse / jee-oxygen / eclipse $ ./eclipse

问题是GTK3。上面的命令强制Eclipse使用GTK2。

答案 1 :(得分：1)

它解决了问题（以及其他像偶尔大量抖动的上下文菜单）才能像这样启动eclipse并使用GTK2代替GTK3：SWT_GTK3=0 ./eclipse

编辑：它似乎也以这种方式工作：https://askubuntu.com/a/838703我使用上述方法丢失了菜单图标。链接的方法没有这个缺陷。
