Check checkbox at runtime

Question

I am totally new to Oracle Forms...
How do I check a checkbox at runtime.
I want to check the checkbox at WHEN-NEW-BLOCK-INSTANCE.
Appreciate any help.
Thank you.

Joseph,
It's the value in the checkbox item that decides whether the checkbox will be
checked or uncheked. Let me give you an example. Suppose you have designed
an item (say ItemA) with the following set up in the property pallete:
Item Type: Checkbox (obviously)
Enabled: Yes
Value when checked: Y
Value when Unchecked: N
Check box mapping with other value: Unchecked (assume for now)
Initial Value: Y
====================================================
At runtime:
When the screen gets invoked, the checkbox shows checked as the
Initial Value is Y
(Answer to Your first question)
You can uncheck or check the checkbox as you like with your
input device (mouse, may be). Y or N will be stored in
the database if you have checked or unchecked the checkbox.
Is that the question?
====================================================
If you want to do progrmatically:
do code as follows in whatever trigger you like according to
your need and restriction that may apply to the trigger.
:<block name>.ItemA := 'Y';
The checkbox would show checked
:<block name>.ItemA := 'N';
The checkbox would show unchecked
====================================================
There is nothing you can do about it with set_item_property.
In fact you don't need to use set_item_property. You are
not going to change any property of the item. As I have
understood, you are working only with the value of the item.
====================================================
Have I answered your question? Let me know if you need to know
anything specific.
