Extending the default F2=Delete function

[uhu]

Hi everyone,

I need some help in extending F2 Delete functionality.

I need F2 to do more than just delete a row in the screen array. Basically I need F2 to delete a row in the screen array and then move the cursor to the first column (Informix default made the cursor to stay in the current column).

Is there a way of doing such thing without having to do a custom delete function & reshuflleing of the array ?
Is there any built in function that check whether F2 is pressed other than the "ON KEY(F2)" ?

Thanks in advance,

Vito

Vito,

In array, screen interaction statement, the default delete hotkey is function key "F2". 4GL has the capability to to reassign other key or combination of keys to replace the original key definitions using OPTIONS statement, for example,

options
delete key control-d

Input array statement has many form management blocks to care of the field level validations and manipulations. One such block is AFTER DELETE, which can be used to implement your requirement. Assuming your first column is "a", the example below illustrates the logic in simple manner.

input array program_array without defaults from screen_array.*
attribute (insert row=1,delete row=1)
on key (accept)
exit input
after delete
next field a
end input
