20 Control Selectors
Publication 2711E-6.15 – November 1998
The Control List Selector with Enter Key object allows the operator
to choose items in a list by selecting them and then pressing Enter.
The maximum number of items in this list is determined by the size
of the list component. For information on changing the size of the
list component, see Chapter 9, Creating Objects, in the
PanelBuilder 1400e Configuration Software for Windows User
Manual.
The Control List Selector with Enter Key consists of the following
components:
This component Does this
Selector List This vertical list can have up to 24 different states (each list
item represents a state). With Double High or Large Font, the
list can contain 12 states.
Up Cursor Button When the operator presses the Up Cursor button, the arrow
in the list moves up by one list entry. If the Down Cursor
button is enabled, you can disable the Up Cursor button. Only
one of the Up and Down Cursor buttons needs to be enabled.
The Up Cursor button auto-repeats at the rate specified in the
Timing Parameters tab of the Terminal Setup dialog box.
Down Cursor Button When the operator presses the Down Cursor button, the
arrow in the list moves down by one list entry. If the Up
Cursor button is enabled, you can disable the Down Cursor
button. Only one of the Up and Down Cursor buttons needs
to be enabled.
The Down Cursor button auto-repeats at the rate specified in
the Timing Parameters tab of the Terminal Setup dialog box.
Enter When the operator presses Enter, the desired option is
chosen and the Selector Control value is updated.
As the operator presses the Up or Down Cursor buttons, an arrow
indicator moves through the list states, wrapping around the top and
bottom. To make a choice, the operator presses Enter
. When Enter is
pressed, the list state is chosen, and the terminal updates the Selector
Control with the value assigned to that state.
Because the operator can move through the list and select different
states at will, the states are not necessarily executed consecutively.
The new state is determined by the cursor’s position in the list when
Enter is pressed.
