[英]Custom error dialog in eclipse e4 application
I'm trying to change the default status handler of our e4 application, because I want to add the full stack trace to it. 我试图更改e4应用程序的默认状态处理程序,因为我想向其添加完整的堆栈跟踪。
So far, I added the following snippet to the plugin xml: 到目前为止,我将以下代码段添加到了插件xml:
<extension
point="org.eclipse.ui.statusHandlers">
<statusHandler
class="our.test.StatusHandler"
id="custom_status_handler"/>
<statusHandlerProductBinding
handlerId="custom_status_handler"
productId="my_product.product">
</statusHandlerProductBinding>
</extension>
The class our.test.StatusHandler looks as follows: 类our.test.StatusHandler如下所示:
public class StatusHandler extends AbstractStatusHandler {
@Override
public void handle(StatusAdapter statusAdapter, int style) {
System.out.println("Hello World");
}
}
But this does not seem to work. 但这似乎不起作用。 The default Error dialog is still shown and there is no output in the console.
默认的“错误”对话框仍然显示,并且控制台中没有输出。
I already looked at this answer and used WorkbenchErrorHandler instead of AbstractStatusHandler, but it does not work either. 我已经看过这个答案,并使用WorkbenchErrorHandler而不是AbstractStatusHandler,但是它也不起作用。
StatusHandler is 3.x compatibility mode and isn't used in a pure e4 application. StatusHandler是3.x兼容模式,在纯e4应用程序中不使用。
You can deal with unhandled exceptions by adding an implementation of IEventLoopAdvisor
in the application context. 您可以通过在应用程序上下文中添加
IEventLoopAdvisor
的实现来处理未处理的异常。 The @PostContextCreate
method of the RCP LifeCycle class is a good place to do this: RCP LifeCycle类的
@PostContextCreate
方法是执行此操作的好地方:
@PostContextCreate
public void postContextCreate(IEclipseContext context)
{
context.set(IEventLoopAdvisor.class, new EventLoopAdvisor(context));
...
}
class EventLoopAdvisor implements IEventLoopAdvisor
{
private final IEclipseContext _appContext;
EventLoopAdvisor(IEclipseContext appContext)
{
super();
_appContext = appContext;
}
@Override
public void eventLoopIdle(final Display display)
{
display.sleep();
}
@Override
public void eventLoopException(final Throwable exception)
{
// Report error
}
}
Note that the call to display.sleep()
in eventLoopIdle
is very important. 请注意,对
eventLoopIdle
display.sleep()
的调用非常重要。
