Trigger firing order

Question

Hi, I use forms 11g and i am trying to do something with the first form that user sees, that is the login form. I am trying to center the form and i have it right is i do that, for example, on WHEN-MOUSE-CLICK event. I tried the WHEN-NEW-FORM-INSTANCE, WHEN-NEW-ITEM-INSTANCE, PRE-LOGON, etc, but none seems do be executed before the form so that it is centered on loading. Anyone knows how can i do that?

Answer 1

This is my code:
PROCEDURE sdf_posiciona_form (nome_da_janela     varchar2, maximiza_mdi number, posicao_800 number) IS
w NUMBER;
h NUMBER;
w1 NUMBER;
h1 NUMBER;
w_tot NUMBER;
h_tot NUMBER;
wn_id WINDOW;
BEGIN
--- Maximiza a MDI Application Window se for o caso
IF maximiza_mdi = 1 THEN
     Set_Window_Property(Forms_Mdi_Window, Window_State, Maximize);
END IF;
--- Determina o tamanho da MDI
w := Get_Window_Property(Forms_Mdi_Window, Width);
h := Get_Window_Property(Forms_Mdi_Window, Height);
wn_id := Find_Window(nome_da_janela);
--- Determina o tamanho da janela e calcula os valores para centrar
w1 := Get_Window_Property(wn_id, Width);
h1 := Get_Window_Property(wn_id, Height);
w_tot := (w-w1)/2;
h_tot := (h-h1)/6;
--- Posiciona a janela
IF w > 600 THEN -- A resolução é > que 800x600
     set_Window_Property(nome_da_janela, position, w_tot, h_tot);
ELSE
     IF posicao_800 = 1 THEN
          set_Window_Property(nome_da_janela, Window_State, Maximize);
     ELSE
          set_Window_Property(nome_da_janela, position, 0, 0);
     END IF;
END IF;
END;
