Unespected calling sequence

[Enrico Maria Giordano]

The following two samples show a different calling sequence between a window and a dialog:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oWnd

    DEFINE WINDOW oWnd

    @ 1, 1 LISTBOX FIELDS;
           ON CHANGE MSGINFO( "OnChange" )

    MSGINFO( "Here" )

    ACTIVATE WINDOW oWnd;
             ON INIT MSGINFO( "OnInit" )

    RETURN NIL

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    DEFINE DIALOG oDlg

    @ 1, 1 LISTBOX FIELDS;
           ON CHANGE MSGINFO( "OnChange" )

    MSGINFO( "Here" )

    ACTIVATE DIALOG oDlg;
             ON INIT MSGINFO( "OnInit" )

    RETURN NIL

Enrico,

Its ok that they behave different:

The window just get created once it is defined: it already has a handle of a window. So the messages shown are: OnChange-Here-OnInit. They happen in the same secuence as defined.

The dialog does not have a window handle until it is activated, so the messages shown are:

1. "Here" (neither the dialog or the listbox have window handles yet).
2. "OnChange" as the control of the dialog is initialized before evaluating the ON INIT clause.
3. Finally "OnInit" as it is evaluated finally, once the dialog its created and its controls are initialized.

Ok, thank you.
