视觉上区分非模态对话框与模态对话框。
有两种类型的对话框，即模态对话框和非模态对话框。
There are two types of dialog boxes: modal and modeless. Modal dialogs boxes are, by far, the most common variety.
相反，在非模态对话框存在的过程中，选择很可能发生改变。
Conversely, the selection is quite likely to change during the lifetime of a modeless dialog box.
不要忘记非模态对话框中经常会有几个按钮，可以立即激活不同的功能。
Modeless dialog boxes frequently have several buttons that immediately invoke various functions.
传统上有两种常用的非模态工具习惯用法，其中非模态对话框是较老的一种。
There have traditionally been two modeless tool idioms in common use. The modeless dialog box is the older of the two.
我们必须打破这种习惯，设计师必须确保所有的非模态对话框有清晰醒目的视觉差异。
We must break this habit . The designer must assure that all modeless dialog boxes are rendered with a clearly noticeable visual difference.

它在逻辑上也是合适的，因为撤销功能在模态对话框中不可用，而在非模态对话框中可用。
This all fits together logically, because the Undo function is unavailable if a modal dialog box is up, but is still usable with modeless ones.
模态对话框冻结了应用程序的状态，因此避免了这些问题，所以非模态对话框的设计和实现比模态对话框要难得多。
Consequently, modeless dialogs can be much more challenging to design and implement than modal dialogs, which avoid these issues by freezing application state.
我们在工具栏上看到一种新式的非模态交互活动的机会，工具栏是非模态的，但它们没有非模态对话框存在的问题。
Here's where we see an opening for a new approach to modeless interactivity. Toolbars are modeless, but they don't introduce the conundrums that modeless dialogs do.
模态对话框和非模态对话框的概念来源于程序员的术语，它们影响了我们的设计，但我们也必须从目标导向的观点来考查对话框。
The concepts of modal and modeless dialogs are derived from programmers' terms. They affect our design, but we must also examine dialogs from a goal-directed point of view.
非模态对话框也必须特别节约像素，它们驻留在屏幕上，占据前面的中心位置。所以必须特别小心，在不必要的情况下不要浪费像素。
They will be staying around on the screen, occupying the front and center location, so they must be extra careful not to waste pixels on anything unnecessary.
丰富视觉非模态反馈是用户可以实时发现的内容，当他们发现后会感到如此奇妙，但是与此同时他们也需要菜单和对话框的支持来寻找需要的信息。
RVMF is something that users will begin to use over time. When they do, they'll think it's amazing; but, in the meantime, they will need support of menus and dialogs to find what they're looking for.
