aEval( oMenu:aItems ) ?? ( Now It's Ok! )
Posted: Mon Nov 03, 2008 01:53 PM
Antonio and friends,

Why this source code not works? Exists a workarea open into cAlias!

Code: Select all Collapse
MENU oMenu POPUP

     MENUITEM "Test One"   ACTION msgIngo( "Test One" )
     SEPARATOR
     MENUITEM "Test Two"   ACTION msgIngo( "Test Two" )
     MENUITEM "Test Three" ACTION msgIngo( "Test Three" )

     aEval( oMenu:aItems, {|oItem| oItem:bWhen := {|| !( ( cAlias )->( lastRec() ) == 0 ) } } )

ENDMENU
Peace and lighting!

Code: Select all Collapse
MENU oMenu POPUP

     MENUITEM "Test One"   ACTION msgIngo( "Test One" )
     SEPARATOR
     MENUITEM "Test Two"   ACTION msgIngo( "Test Two" )
     MENUITEM "Test Three" ACTION msgIngo( "Test Three" )

ENDMENU

aEval( oMenu:aItems, {|oItem| oItem:bWhen := {|| !( ( cAlias )->( lastRec() ) == 0 ) } } )

Julio,

Place a MsgBeep() there to check if the code is properly evaluated:
Code: Select all Collapse
aEval( oMenu:aItems, {|oItem| oItem:bWhen := {|| MsgBeep(), !( ( cAlias )->( lastRec() ) == 0 ) } } )

Has cAlias a right value ?
regards, saludos

Antonio,

cAlias is "ENT" and "ENT" is a workarea open to my sql result... when I try ( cAlias )->( browse() ), the command show me the rows.

And yes, I tried to use a msginfo( "test" ) in the same place, but still not works!
Code: Select all Collapse
MENU oMenu POPUP

     MENUITEM "Test One"   ACTION msgIngo( "Test One" )
     SEPARATOR
     MENUITEM "Test Two"   ACTION msgIngo( "Test Two" )
     MENUITEM "Test Three" ACTION msgIngo( "Test Three" )

     aEval( oMenu:aItems, {|oItem| msgInfo( "test" ), oItem:bWhen := {|| !( ( cAlias )->( lastRec() ) == 0 ) } } )

ENDMENU



Outch! :-)
Peace and lighting!

As Daniel told you, you have to call AEval() after ENDMENU

Antonio,

Ok, but I already tried that! Simply does not work! :-)
I have tried with menu "non popup" and work very fine!

Julio,

Here you have a working example. Please keep in mind that the WHEN expression is evaluated when the menu is going to be created.
Code: Select all Collapse
#include "FiveWin.ch"

function Main()

   local oWnd

   DEFINE WINDOW oWnd
   
   ACTIVATE WINDOW oWnd ;
      ON RIGHT CLICK ShowPopup( nRow, nCol, oWnd )

return nil

function ShowPopup( nRow, nCol, oWnd )

   local oPopup
   
   static n := 1

   MENU oPopup POPUP 2007
      MENUITEM "One"   WHEN n++ % 2 == 0
      MENUITEM "Two"   WHEN n++ % 2 == 0
      MENUITEM "Three" WHEN n++ % 2 == 0
   ENDMENU   

   ACTIVATE POPUP oPopup WINDOW oWnd AT nRow, nCol

return nil
regards, saludos

I have this situation:


Taking into account is that when a block of code, a refresh would not be doing the upgrade of code at "!( ( cAlias )->( lastRec() ) == 0 )" ?

When the number of registers is 0 (zero), the button "OperaçÔes" with a menu popup need to be disabled!

Even after they have created? Or not!?
Peace and lighting!

Antonio,

I've done this, thank you!

However, there are two menu items that need to be empowered independent of the situation, I only not have put in the example.

Exists another way to do it automatically??

Peace and lighting!

JĂșlio,

This change is required in Class TMenu Method Activate()
Code: Select all Collapse
      ...
      oWnd:oPopup = Self
      ::Initiate()   // New !!!

      TrackPopup( ::hMenu, 2, aPoint[ 1 ], aPoint[ 2 ], 0, oWnd:hWnd )
      ...

With that change, this example works fine:
Code: Select all Collapse
#include "FiveWin.ch"

function Main()

   local oWnd, oBtn

   DEFINE WINDOW oWnd

   @ 3, 3 BTNBMP oBtn OF oWnd SIZE 80, 25
   
   oBtn:oPopup = BuildMenu()
   
   ACTIVATE WINDOW oWnd 

return nil

function BuildMenu()

   local oPopup
   
   static n := 1

   MENU oPopup POPUP 2007
      MENUITEM "One"   WHEN n++ % 2 == 0
      MENUITEM "Two"   WHEN n++ % 2 == 0
      MENUITEM "Three" WHEN n++ % 2 == 0
   ENDMENU   

return oPopup
regards, saludos
