Figure 2-3. Installation Program Widgets as seen in Disk Druid
Here is a list of the most important widgets shown in Figure 2-2 and Figure 2-3:
•
Window — Windows (usually referred to as
dialogs
in this manual) appear on your screen through-
out the installation process. At times, one window may overlay another; in these cases, you can only
interact with the window on top. When you are finished in that window, it disappears, allowing you
to continue working in the window underneath.
•
Checkbox — Checkboxes allow you to select or deselect a feature. The box displays either an
asterisk (selected) or a space (unselected). When the cursor is within a checkbox, press [Space] to
select or deselect a feature.
•
Text Input — Text input lines are regions where you can enter information required by the installa-
tion program. When the cursor rests on a text input line, you may enter and/or edit information on
that line.
•
Text Widget — Text widgets are regions of the screen for the display of text. At times, text widgets
may also contain other widgets, such as checkboxes. If a text widget contains more information
than can be displayed in the space reserved for it, a scroll bar appears; if you position the cursor
within the text widget, you can then use the [Up] and [Down] arrow keys to scroll through all
the information available. Your current position is shown on the scroll bar by a
#
character, which
moves up and down the scroll bar as you scroll.
•
Scroll Bar — Scroll bars appear on the side or bottom of a window to control which part of a list or
document is currently in the window’s frame. The scroll bar makes it easy to move to any part of a
file.
•
Button Widget — Button widgets are the primary method of interacting with the installation pro-
gram. You progress through the windows of the installation program by navigating these buttons,
using the [Tab] and [Enter] keys. Buttons can be selected when they are highlighted.
•
Cursor — Although not a widget, the cursor is used to select (and interact) with a particular widget.
As the cursor is moved from widget to widget, it may cause the widget to change color, or the cursor
itself may only appear positioned in or next to the widget. In Figure 2-2, the cursor is positioned on
the
OK
button. Figure 2-3, shows the cursor on the
Edit
button.
2.2.1. Using the Keyboard to Navigate
Navigation through the installation dialogs is performed through a simple set of keystrokes. To move
the cursor, use the [Left], [Right], [Up], and [Down] arrow keys. Use [Tab], and [Alt]-[Tab] to cycle
forward or backward through each widget on the screen. Along the bottom, most screens display a
summary of available cursor positioning keys.
