FRM-VIDEO -(Hands-On
04) How to use Radio Buttons
Radio Buttons
Introduction
A radio button group
allows values stored in a data source column to display in a more
graphical fashion, by having one radio button assigned to each
possible value. Once a radio group is created, each radio button
within it must be assigned a unique value.
Hands-On
Your users have indicated
that they keep track of their salesmen's commission plans. The company
has commission plans "A," "B," "C," and
Blank. The "Blank" commission plan means that this is not
applicable to salesman. Middle Management would like to stream line
their salesmen contract assignment process. The company assigns
salesmen, based on their commission performance. Those salesmen with
higher than average commission will be rewarded and assigned to
lucrative contracts.
To accommodate Management's
need for tracking high performing salesmen, they ask you to change the
commission plan item to the radio button style.
See Figure 6.
Your tasks are:
1- Change the commission
plan column to the Radio Buttons.
2- Change the "order
tab page" to implement the Radio Buttons.
3- Run and test all user
functional requirements.
Note: The Radio Buttons are
useful when there are two or more possible values but only one value
can be true.
F In this Hands-On,
you will learn how to: add and use Radio Buttons, use tab canvas, use
"object navigator," use "Data Blocks," use "Layout Editor,"
use "Property Palette," use "Run Form," and "Execute Query."
Figure 6
Open a Module
In the "Object Navigator"
window, highlight Forms. Go to the Main menu and choose "File,"
select "Open" to open an existing form (customer_orders_V03)
from the "iself"
folder.
Save a module
Click on the "CUSTOMER_ORDERS_V03"
form. The color changes to blue. Then change its name and save the
Form name as version 04 (customer_orders_v04). This way the
original form is untouched.
Expand ORD data block
In the "Object Navigator"
window, expand "Data Blocks." Then expand the order's data blocks
(ORD) and its items.
Change an item in Radio
Group
Right click on the "Commission
Plan" item (COMMPLAN) to open its Property Palette. In the Property
Palette window, change its item type to "Radio Group."
Change "Initial Value" to "A," then press the
enter key or click on any box to apply the changes. Close the window.
Notice the icon next to the
Commission Plan (COMMPLAN) was changed in the "Object Navigator"
window and in the Layout Editor the Commission Plan item (COMMPLAN)
has disappeared.
In the Object Navigator
window, expand commission plan. Notice that there is no radio button
associated with the Radio Group item.
Do some layout adjustments
before creating the radio button. You need at least four radio
buttons. Therefore you need more space to put the objects on the
canvas. See above figure.
Moving objects
Select the shipdate, total
and scrollbar items and move the cursor inside any handlers and drag
the selected objects to the right. To select multiple objects, push
and hold the control key and then click on the objects that you wish
to be part of group. You can also, go outside of the objects and click
and hold the cursor on the canvas and move it until all the objects
are in the box. Release the mouse. Now, you selected all your objects.
Go anywhere in side of the handlers to move your selected objects.
You can also click on the
right, left, up, and down arrow keys to move the objects. Try it
number of times. It is fun.
To deselect the objects,
just move your cursor outside of the selected objects and click. All
your handlers will be disappeared.
Create a Radio Button
In the "Layout Editor"
window click on the "radio button" icon. Now, if you move your
cursor in side of canvas, your cursor changes to a plus sign.
Move your cursor on a
position that you want to have your Radio Button and click. The "Radio
Groups" window will appear. In the "Radio Groups" window, select
the radio group "COMMPLAN" and click "OK."
Adjust the size if needed.
In the Layout Editor window, right click on the new Radio Button (RADIO_BUTTONxx)
to open its Property Palette.
Radio Button 1:
Change a Radio Button
Property Sheet
In the Property Palette,
change its name to A. Change "Label" to blank. Change "Radio
Button Value" to A. Change "Prompt" to A. Change
"Prompt Attachment Edge" to top. Then close the window.
Make some layout
adjustments if needed.
Copy the object and paste
it three times. The copy will be pasted on the top of each other. You
need to select them one by one and drag them to be appeared next to
each others. Make sure that when you copy the object to place the
Radio Button item in the "COMMPLAN" Radio Group.
Open the new Radio Buttons
property palette. And change their "name", their "radio
button value", and their "prompt" properties.
Radio Button 2:
In the Property Palette,
change its name to B. Change "Label" to blank. Change "Radio
Button Value" to B. Change "Prompt" to B. Change
"Prompt Attachment Edge" to top. Then close the window.
Radio Button 3:
In the Property Palette,
change its name to C. Change "Label" to blank. Change "Radio
Button Value" to C. Change "Prompt" to C. Change
"Prompt Attachment Edge" to top. Then close the window.
Radio Button 4:
In the Property Palette,
change its name to "BLANK." Change "Label" to blank. Change
"Radio Button Value" to " ". Change "Prompt"
to "Blank." Change "Prompt Attachment Edge" to top. Then
close the window. The blank means that the commission plan is not
applicable to this transaction. Then close the window.
Do some layout adjustments
if needed.
Navigate through the tab
pages layout by clicking on them.
Run the Form Runtime
Run the Form.
Execute Query
Click "Execute Query"
and navigate through the customers.
Test and check the changes.
When you are done with all
the testing, then close the application and save the changes.

Q: Your users have
indicated that they keep track of their salesmen's commission plans.
The company has commission plans "A," "B,"
"C," and Blank. The "Blank" commission plan means that
this is not applicable to salesman. Middle Management would like to
stream line their salesmen contract assignment process. The company
assigns salesmen, based on their commission performance. Those
salesmen with higher than average commission will be rewarded and
assigned to lucrative contracts.
To accommodate Management's
need for tracking high performing salesmen, they ask you to change the
commission plan item to the radio button style.
See Figure 6.
Your tasks are:
1- Change the commission
plan column to the Radio Buttons.
2- Change the "order
tab page" to implement the Radio Buttons.
3- Run and test all user
functional requirements.
Note: The Radio Buttons are
useful when there are two or more possible values but only one value
can be true.
