Microsoft Windows CE general terms
The following text explains several basic terms that appear in computer terminology. They are
needed to understand fully thefollowing chapters.
Label
A label is a fixed static text whose function is to describe another element or its function/me-
aning. Labels may also serve themselves as a source of information.
Checkbox
The checkbox is a square shaped element that can be either checked (turned on) or not. The
checkbox is toggled by pressing its square shape or by selecting it using Tab keys and toggling
it using the Space button.
Radio button
The radio button is a circular symbol within a group that offers different choices to the user.
Selecting one button from within the array automatically cancels previous selection (just like
old-style radios do). Pick one button from the group using Tab keys and press Space.
Button/Icon
The button is an element on the display that, if activated, will perform its assigned function.
You can press the button directly on the touch sensitive display or you can pick the desired
button using the Tab keys and pressing Space afterwards. The icon is in fact a button but
contains iconic representation of the intended function. The icon is used in the same way the
button is.
Text row
Text row represents the place where data can be entered. A typical example of this is entering
a cashier’s password into the text row.
Pull-down menu
The pull-down menu allows you to pick one option from several options. The visual differen-
ce between the pull-down menu and the text row is the small square carrying an arrow on its
