Working on Mdi

[Silvio.Falconi]

When I Open the Window child I made


CLASS TPaziente
DATA oWin

METHOD New() CLASS TPaziente

....

if ::oWin == nil

::oPaziente := TClienti():New()
::oPaziente:SetOrder( "FIRST" )
::oPaziente:GoTop()
::cTitulo := ""

DEFINE ICON ::oIcon RESOURCE "

DEFINE WINDOW ::oWin MDICHILD
....


else
::oWin:SetFocus()
endif

RETURN Self

this is to avoid opening the same window
but unfortunately it does not work because it reopens again how can I not make the same window open again?

Dear Silvio,

Do you use static oPaziente ?

Perhaps I found a solution But I not understood if it can go good

On Main.prg

Code: Select all  Expand view  RUN

Static oItem[40], oBtns[20]

On buttonbar of Main.prg

Code: Select all  Expand view  RUN

DEFINE BUTTON oBtns[1] RESOURCE "paciente" OF ::oBar NOBORDER ;
      ACTION TPaziente():New(oItem[1],oBtns[1]):Activar(oItem[1],oBtns[1])  

On menu of Main.prg

Code: Select all  Expand view  RUN

MENUITEM oItem[1] PROMPT "Anagrafica pazienti" ACTION TPaziente():New(oItem[1],oBtns[1]):Activar(oItem[1],oBtns[1])   RESOURCE "pazienti"

On TPaziente.prg

Code: Select all  Expand view  RUN

MemVar oMOpc, oBBar

I don't know if it is right to use Memvar, in clipper I never used them or so I remember

On method New()of Tpaziente

Code: Select all  Expand view  RUN

IF !Empty(oItem)
      oItem:Disable()
   ENDIF

   IF !Empty(oBtnB)
      oBtnB:Disable()
   ENDIF

   oMOpc:=oItem
   oBBar:=oBtnB

on Method activar()

Code: Select all  Expand view  RUN

METHOD Activar(oItem,oBtnB) CLASS TPaziente
   ACTIVATE WINDOW ::oWinClients MAXIMIZED ;
   VALID     (::oWinClients:=Nil,Exit_Wnd(oItem,oBtnB),.T.)
   RETURN NIL

Code: Select all  Expand view  RUN

STAT FUNC Exit_Wnd(oItem,oBtnB)
    oBtnB:Enable()
    oItem:Enable()
RETURN (.T.)

So, This blocks both the main menu and the buttonbar of main.prg

For Now it seem run ok , I saw this technique on a source code by Alfredo Arteaga which I hope is fine even if I haven't heard from it for years

But there would be a problem.

while in the menu I see the locked option



the button of buttonbar is disabled but not is on different color



but I check it is disabled

any solution ?
