Common Tasks In Creating Operator
Interfaces
In the following exercises, you will learn how to implement many operator
interface features. Specifically, you will learn how create menus, create
warnings, create a status panel, and import bitmaps to add more visual
impact to programs. All of the labs will give you a chance to customize the
interfaces.
Lab 10-1: Using Menus
In this exercise, you will create an operator interface that includes a menu
with three choices:
die1, die2, and die3. When the operator selects a
choice, a function by the same name will be called that displays a die with
one, two, or three dots on its top face. This program simulates a situation
where the operator must choose a test to run from a menu. You will also
learn how to import a bitmap to change the appearance of an icon. This will
be called the Dice Program.
Begin by creating the three
UserFunctions.
1. Select
Device ⇒ UserFunction.
Although you could use any icon to display the imported bitmap, this
example uses the
Picture object.
2. Select
Display ⇒ Picture and place it in the UserFunction.
3. Open the
Picture object menu, click Properties, then deselect Show
Title Bar
under Open View. Select die1.gif under Picture, click
Scaled, then OK.
Note To access an object menu when Show Title Bar is turned off, click the
right button over the object.
