I'm writing code using a dialog, i've this problem:
procedure pluto
begin
proc1;
show_window('dialog');
proc2;
end;
Since 'dialog' is modal, as said on oracle docum., show_window is
a non blocking function call like go_item(first dialog item).
If i want to sequentially execute proc2 after closing the dialog I've to call proc2 in:
1- the trigger managing ok or cancel buttons. Or..
2- the when-window-close trigger at form level.
From the p.o.v. of sw. eng. this is a mistake, becase the secret encapsulated in the procedure pluto cannot be distibuted across other things not really concerning the secrets of pluto.
Is there any way to get or to emulate a blocking show_window ?
many thanks!!!

ok, let's synthesize my problem: I'd like to emulate the lov behavior, when I show the lov, with show_lov, the code calling show_lov wait until the lov is closed, then show_lov returns true or false, respect. if the user have or not selected any item in the lov.
This is an example, if u want another ex. think about the show_alert behavior...
The default behavior of a show_windows(windows_id) is rendering the window to the screen and then continue the execution of the next instruction following the show_window call, therefore the show_window-calling instructions block does not wait for the rendered windows to be closed.
The question is: is there any way of write a my_show_window(modal_win_id) proc/func suspending the main running sequence until the showed modal windows closes?

Come on.. You can always work around with this..You can provide your logic to execute certain statements..for e.g you said
Proc1 ;
show_window('window') ;
proc2 ;
you want to hold proc2 till user dont exits called window..Now either you can do it with global variables or by coding proc2 in the exit button of the called window..
Ther's nothing so serious issues about that...
