Enables background tasks that interact with the user interface, communicating via events raised on the user-interface thread.
启用与使用者介面互动的背景工作，透过使用者介面执行绪上引发的事件来沟通。
A user-interface thread is commonly used to handle user input and respond to user events independently of threads executing other portions of the application.
使用者介面执行绪通常用来处理使用者输入和回应与执行绪没有关系之执行应用程序其他部分的使用者事件。
This is because remote invocations in JSR 172 are blocking calls, and if invoked in the main event thread, the user interface will freeze until the remote invocation completes.
由于JSR 172中的远程调用是按模块进行的，而且如果在主事件线程中调用，用户界面会冻结，直到远程调用结束。
When a pluglet is executed, it runs on the Rational Software Architect (User Interface) UI thread.
当运行pluglet 时，它在RationalSoftware Architect（用户界面）UI 线程上运行。
The PresentationReconciler class updates the text's appearance with every keystroke, and the Reconciler class runs in a daemon thread, parsing the document without holding up the user interface (UI).
presentationreconciler类根据每次击键更新文本的外观，而Reconciler类运行一个守护线程，不必将用户界面(UI)挂起就能解析该文档。
AWT and Swing use this model, in which there is a GUI event thread, and all work that causes changes in the user interface must execute in that thread.
AWT和Swing就使用这个模型，在这个模型中有一个GUI事件线程，导致用户界面发生变化的所有工作都必须在该线程中执行。
Eclipse has a single thread for managing the user interface, and some SWT API methods may only be called from that thread. (see Resources for more information).
Eclipse有一个用于管理用户界面的线程，而且某些SWTAPI方法只能通过该线程调用(有关更多信息，请参阅参考资料)。
Specifically, if everything is happening in a single thread, performing long operations such as network access or database queries on the UI thread will block the whole user interface.
特别是，如果把所有的事件都放在主线程中来处理，需要长时间来处理的事件比如网络访问或者数据库查询，会阻塞整个UI。
So, you must not manipulate your UI from a worker thread-you must do all manipulation to your user interface from the UI thread.
因此不允许从工作线程中操作ui——只能从UI线程中操作用户界面。
This thread is very important because it is in charge of dispatching events to the appropriate user interface widgets, including drawing events.
主线程非常重要，因为它负责把事件分发给相应的用户界面widget——包括屏幕绘图事件。
In third chapter, the thesis particularly introduce the method by using the multi-thread User Interface (UI) and the Dialog Model to realize the project software structure.
第三章中详细介绍了运用多线程用户界面实现软件结构和运用对话框实现软件结构的方法。
On top of all that, the operating system can also adjust thread priorities dynamically as an application's user interface is moved between foreground and background.
除此之外，当应用程序的用户界面在前台和后台之间移动时，操作系统还可以动态调整线程优先级。
Occurs on the application UI (user interface) thread when the user lifts the tablet pen from the digitizer.
当触笔移到数字化仪上时，在应用程序ui(用户界面)线程上发生。
Threads are divided into Worker Thread and User Interface Thread.
线程分为辅助线程(工作者线程)和用户界面线程。
The debugger user interface (UI) may want to take this information into account if it displays the operating system (OS) suspend count of the thread to the user.
如果调试器用户界面(UI)要向用户显示线程的操作系统(OS)挂起计数，便可能需要考虑此信息。
Since everything happens on a single thread performing long operations, like network access or database queries, on this thread will block the whole user interface.
一旦所有的事件都在一个线程中进行耗时的操作，比如说在这个线程上进行网络连接，数据库访问，会阻塞程序的界面响应。
This event is raised on the application's main thread with the other user-interface events.
此事件随其他用户界面事件在应用程序主线程上引发。
This event is raised on the application's main thread with the other user-interface events.
此事件随其他用户界面事件在应用程序主线程上引发。
