Fonts

If your program supports typography and text layout using user-selectable fonts, you should use the Fonts window to obtain the user’s font selection. Users can select fonts and sizes in both the standard (Figure 6-5) and the minimized (Figure 6-6) view of the Fonts window. In the standard view, there are also controls for fine-tuning the display characteristics of fonts. Most important, the Fonts window is implemented for you. You do not have to create a Fonts menu or other special user interface to display and gather font information from the user.

如果您的程序支持使用用户选择的字体来打印和布局，您应该使用标准的字体窗口来获得用户选择的字体。在字体窗口的标准视图和小型视图中用户都可以选择字体和大小（图6-5）。在标准视图中，还有一些优化字体显示的控件。最重要的，字体窗口是已经为您实现好了的。您没必要创建一个字体菜单或者其他特定的用户接口来显示和收集字体信息。

The Fonts window also provides advanced typography controls for fonts that support those options. The user can open a Typography inspector by choosing Typography from the action menu. Figure 6-7 shows the typography controls for the Zapfino font.

标准字体窗口同样提供了设置字体排版效果的控件。用户可以从操作菜单中选择版面来打开字体排版查看器。图6-7显示了Zapfinfo字体的排版效果控件。
