unshaded part of the scroll bar) shows the position and the size of the
visible information in relation to the information that is available. As the
window is scrolled, the upper and lower bold bars change size to reflect the
amount of information that is available for display in both up and down
directions. All available information is visible if no slider box is shown.
6Non-Sizeable Window Border
A non-sizeable window border cannot be used to increase or decrease the
size of the window.
7Dialog or Message Box
Dialog and message boxes are displayed when the application needs
additional information, or when information is presented to the operator.
Dialog and message boxes can also include radio buttons, check boxes,
and push-buttons to allow the operator to respond to an application.
8Horizontal Scroll Bar
The scroll bars are used to move additional, unseen information into view
on the screen. By clicking on the left or the right scroll bar arrows, current
information can be scrolled (moved) horizontally off the screen and new
information scrolled horizontally on to the screen. The bold (dark colored)
portions of the scroll bars show whether, and how much, information is
available to be displayed. Typically,these areas are not bold. They are of a
lighter color than the slider box. As the window is scrolled, the left and the
right bold bars change size to reflect the amount of information that is
available for display in both directions.
9Push buttons
Push buttons allow the operator to select a particular action, which occurs
immediately.The ellipsis (...) following a menu item indicates that a pop-up
window will be opened if that item is selected.
10Check Boxes
A check box is a two-part control consisting of a square box and text.
Unlike radio buttons, one or more boxes can be selected. Toselect a check
box, place the pointing device on the box and click. The box is marked with
an X to show that it was selected. Click on the text again to cancel the
choice.
11Radio Buttons
Radio buttons allow the operator to choose between two or more possible
responses or actions. Only one choice is allowed within any set of radio
buttons. If a second choice is made, the first choice is cancelled. The action
selected by the radio button typically occurs after all screen selections are
made and a push-button is selected to initiate the actions.
12Pull-Down Menu
Pull-down menus are an expansion of an action bar item. The pull-down is
displayed when the corresponding action bar item is selected. The ellipsis
(...) following a menu item indicates that a pop-up window will be opened if
that item is selected. Aright-pointing triangle (Ê) at the right of a selection
item indicates that this selection has an associated hidden pull-down that
will be displayed if the item is selected.
Click on the desired action to highlight the item. If a line item is reduced in
contrast (dimmer) from other items (Action 2 in Figure 36on page 89), the
item is not available for selection.
