Silvio,

When a main MDI window is used, the preview is created inside a MDICHILD window. We don't set a menu to the preview child window, as it will replace the main pulldown menu (as MDICHILD windows can't have a menu inside them). You can easily modify source\classes\rpreview.prg in case that you want to set the MDICHILD menu.

This sample is working fine. Please test it and check if you can reproduce the error that you mention, thanks:

Code: Select all  Expand view

#include "FiveWin.ch"

function Main()

   local oWnd

   DEFINE WINDOW oWnd TITLE "Test" MDI ;
      MENU BuildMenu()

   ACTIVATE WINDOW oWnd

return nil

function BuildMenu()

   local oMenu
   
   MENU oMenu
      MENUITEM "Test"
      MENU
         MENUITEM "Preview" ACTION Preview()
      ENDMENU   
      oMenu:AddMdi()
   ENDMENU
   
return oMenu   

function Preview()

   local oPrn
   
   PRINTER oPrn Preview
      PAGE
         oPrn:Say( 2, 2, "Test" )
      ENDPAGE
      PAGE
         oPrn:Say( 2, 2, "Test" )
      ENDPAGE
   ENDPRINTER
   
return nil

Antonio,
your sample run well

I use the same prev32.dll

but on your sample I can see icons 'xp on gray bar

on my application I see the old icons on bar office 2007 style

why ?
Perhaps I have an error on RPreview class
because Now when press also the X ( window exit) i make error Nwidht
can I send U in private my little code ?

[Silvio]

perhaps I found an error

when on an applicaton we write

Code: Select all  Expand view

DEFINE BUTTONBAR oBar 3DLOOK BUTTONSIZE 25,25 OF oWnd 2007


we can see the bar with office 2007 like

and if go on the preview we can see old icon of the rpreview on buttonbar office 2007 style


but if we write

Code: Select all  Expand view

DEFINE BUTTONBAR oBar 3DLOOK BUTTONSIZE 25,25 OF oWnd


if go on the preview we can see xp icon of the rpreview on a gray buttonbar

perhaps there is an error

We when write DEFINE BUTTONBAR oBar 3DLOOK BUTTONSIZE 25,25 OF oWnd 2007
we want see buttonbar style office 2007 and the xp icons ...

Silvio,

Its coded that way. The preview detects if you are using 2007 look and then it uses the same style for its buttons bar:

[Silvio]

ok but also in your sample i see buttonbar 2007 style and all old icons no xp
you made it in this way ?


then i not found a solution for the second error (nwidth)

I recompile old school application made with fw 2.6 two years ago i think.

Now i recompile it with 7.12 but when i go to two pages it make error i not know why , the last exe not made this type of error , i must recompile another school application but i am sorry if it make error..
how i can make ?

[Silvio]

Now I recompiled with old Rpreview.prg ( NO CLASS)

It run ok and not make error ( nwidth() )

When I recompiled with NEW class Rpreview there is error !!!!!!!!!!!!!!

Do you want control it please ?

[Antonio Linares]

Silvio,

Please tell us how to reproduce the error.

We have provided you a sample that works fine and does not error. Please provide us a sample that errors, thanks

Fixed, thanks:



You just need to modify source\classes\rpreview.prg and change the name of the used resources into the same name ended with "2".

[Silvio]

please can you send me in private the rpreview class?

[Antonio Linares]

Silvio,

Already sent

[Silvio]

Antonio,
I sent you the test
