firing in text item

1 Answer

Answer :

Triggers can be classified as Key Triggers, Mouse Triggers
,Navigational Triggers.
Key Triggers :: Key Triggers are fired as a result of Key action.e.g ::
Key-next-field, Key-up,Key-Down
Mouse Triggers :: Mouse Triggers are fired as a result of the mouse
navigation.e.g. When-mouse-button-presed,when-mouse-
doubleclicked,etc
Navigational Triggers :: These Triggers are fired as a result of
Navigation. E.g : Post-Text-item,Pre-text-item.
We also have event triggers like when ?new-form-instance and when-
new-block-instance.
We cannot call restricted procedures like go_to(?my_block.first_item?)
in the Navigational triggers
But can use them in the Key-next-item.
The Difference between Key-next and Post-Text is an very important
question. The key-next is fired as a result of the key action while the
post text is fired as a result of the mouse movement. Key next will not
fire unless there is a key event. The sequence of firing in a text item
are as follows ::
a) pre - text
b) when new item
c) key-next
d) when validate
e) post text
