| Checkboxes |
Checkboxes
are generally used for on/off settings. A checkmark means the setting
is on; an empty box means it's off. Click on the box
to turn the labeled setting on or off.
In some instances, the checkmark may be shown in a light gray color.
This doesn't necessarily mean that the control is
disabled (see "Grayed-out (inactive) controls," earlier
in this chapter), but rather that the value is neither on nor off.
Here's an example: select some files in Explorer or
on your Desktop, right-click on one of them, select Properties, and
you'll get a dialog similar to Figure 3-5. The checkmark is missing for the Read-only
and Hidden attributes, but appears gray for the Archive attribute
because some of the selected files have it enabled, and others
don't.
Figure 3-7. Checkboxes allow you to turn settings on or off
