Disabling/removing menu

Roberto Parisi · Post by **Roberto Parisi** » Fri Jan 25, 2008 2:09 pm

Hi Antonio,
I can't disable or remove menuitems... is it a FWPPC bug??

I post you a sample:

#include "FWCE.ch"

static oMenu1, oMenu2, oMenu

function Main()

local oWnd

DEFINE WINDOW oWnd TITLE "TestMenu" ;
MENU BuildMenu()

@0,0 button "Disable" size 100, 20 action oMenu1:Disable() pixel
@30,0 button "Remove" size 100, 20 action RemoveMenu(oMenu:hMenu, 1) pixel

ACTIVATE WINDOW oWnd ;
ON CLICK MsgInfo( "Click!" )

return nil

//----------------------------------------------------------------------------//

function BuildMenu()

DEFINE MENU oMenu RESOURCE 102

REDEFINE MENUITEM oMenu1 ID 110 OF oMenu ACTION MsgInfo( "First" ) when .F.

REDEFINE MENUITEM oMenu2 ID 120 OF oMenu ACTION MsgInfo( "Second" )

return oMenu

//----------------------------------------------------------------------------//

#pragma BEGINDUMP
#include "windows.h"

HB_FUNC(REMOVEMENU) {
RemoveMenu((HMENU) hb_parnl(1), (UINT) hb_parnl(2), MF_BYPOSITION);
}

#pragma ENDDUMP

Roberto,

We are going to review it and we will provide you an answer asap

Roberto,

Please try these functions:

Code: Select all

TB_ENABLE( oMenu:hMenu, oMenuItem:nId )
TB_DISABLE( oMenu:hMenu, oMenuItem:nId )

Code: Select all

HB_FUNC( TB_DISABLE )
{
   HWND hMenuBar = (HWND)SHFindMenuBar(hb_parnl(1));

   TBBUTTONINFO tbbi;
   tbbi.cbSize = sizeof(tbbi);
   tbbi.dwMask = TBIF_STATE;
   tbbi.fsState = TBSTATE_INDETERMINATE;

   SendMessage( hMenuBar, TB_SETBUTTONINFO, hb_parnl( 2 ), ( LPARAM ) &tbbi ); 
   return; 
}

HB_FUNC ( TB_ENABLE )
{
   HWND hMenuBar = ( HWND ) SHFindMenuBar( hb_parnl( 1 ) );

   TBBUTTONINFO tbbi;
   tbbi.cbSize = sizeof(tbbi);
   tbbi.dwMask = TBIF_STATE;
   tbbi.fsState = TBSTATE_ENABLED;

   SendMessage( hMenuBar, TB_SETBUTTONINFO, hb_parnl( 2 ), ( LPARAM ) &tbbi); 
   return; 
}

Thx Antonio but it seems doesn't work:

This is the full sample code:

#include "FWCE.ch"

static oMenuItem1, oMenuItem2, oMenu

function Main()

local oWnd

DEFINE WINDOW oWnd TITLE "TestMenu" ;
MENU BuildMenu()

@0,0 button "Disable" size 100, 20 action TB_Disable(oMenu:hMenu, oMenuItem1:nID) pixel
@30,0 button "Remove" size 100, 20 action TB_Enable(oMenu:hMenu, oMenuItem1:nID) pixel

ACTIVATE WINDOW oWnd ;
ON CLICK MsgInfo( "Click!" )

return nil

//----------------------------------------------------------------------------//

function BuildMenu()

DEFINE MENU oMenu RESOURCE 102

REDEFINE MENUITEM oMenuItem1 ID 110 OF oMenu ACTION MsgInfo( "First" ) when .F.

REDEFINE MENUITEM oMenuItem2 ID 120 OF oMenu ACTION MsgInfo( "Second" )

return oMenu

//----------------------------------------------------------------------------//

#pragma BEGINDUMP
#include "windows.h"
#include "commctrl.h"

HB_FUNC( TB_DISABLE )
{
HWND hMenuBar = (HWND)SHFindMenuBar(hb_parnl(1));

TBBUTTONINFO tbbi;
tbbi.cbSize = sizeof(tbbi);
tbbi.dwMask = TBIF_STATE;
tbbi.fsState = TBSTATE_INDETERMINATE;

SendMessage( hMenuBar, TB_SETBUTTONINFO, hb_parnl( 2 ), ( LPARAM ) &tbbi );
return;
}

HB_FUNC ( TB_ENABLE )
{
HWND hMenuBar = ( HWND ) SHFindMenuBar( hb_parnl( 1 ) );

TBBUTTONINFO tbbi;
tbbi.cbSize = sizeof(tbbi);
tbbi.dwMask = TBIF_STATE;
tbbi.fsState = TBSTATE_ENABLED;

SendMessage( hMenuBar, TB_SETBUTTONINFO, hb_parnl( 2 ), ( LPARAM ) &tbbi);
return;
}

#pragma ENDDUMP

Roberto,

This sample is working fine. No need for the functions that I told you, sorry:

Code: Select all

#include "FWCE.ch" 

static oMenuItem1, oMenuItem2, oMenu 

function Main() 

local oWnd 

DEFINE WINDOW oWnd TITLE "TestMenu" ; 
MENU BuildMenu() 

@  0, 0 button "Disable" size 100, 20 action oMenuItem1:Disable() pixel 
@ 30, 0 button "Enable" size 100, 20 action oMenuItem1:Enable() pixel 

ACTIVATE WINDOW oWnd ; 
ON CLICK MsgInfo( "Click!" ) 

return nil 

//----------------------------------------------------------------------------// 

function BuildMenu() 

DEFINE MENU oMenu RESOURCE 102 

REDEFINE MENUITEM oMenuItem1 ID 110 OF oMenu ACTION MsgInfo( "First" ) 

REDEFINE MENUITEM oMenuItem2 ID 120 OF oMenu ACTION MsgInfo( "Second" ) 

return oMenu 

//----------------------------------------------------------------------------//

Sorry Antonio, but it doesn't work. After pressing "Disable" I still can press on menuitem first and get the MsgInfo()

Have you tried with your testmenu.rc sample?

Roberto,

You must be doing something wrong as here it is working fine.

Please download it and test it:

Roberto Parisi · Post by **Roberto Parisi** » Mon Jan 28, 2008 8:44 am

Ok Antonio, I understand.

I use another rc file (the same of your testmenu.prg sample) without child menuitems.

This is the rc file:

#ifdef _CE
#include "c:\vce\include\arm\windows.h"
#include "c:\vce\include\arm\commctrl.h"
#endif

#define I_IMAGENONE (-2)
#define IDS_HELP 104

#ifdef _CE
102 RCDATA
BEGIN
102, 2,
I_IMAGENONE, 110, TBSTATE_ENABLED, TBSTYLE_AUTOSIZE, 202, 0, 0,
I_IMAGENONE, 120, TBSTATE_ENABLED, TBSTYLE_AUTOSIZE, 203, 0, 0,
END
#endif

STRINGTABLE DISCARDABLE
BEGIN
202 "First"
203 "Second"
END

102 MENU DISCARDABLE
BEGIN
MENUITEM "", 110
MENUITEM "", 120
END

Roberto Parisi

Roberto,

So is it working fine now for you ?

Roberto Parisi · Post by **Roberto Parisi** » Mon Jan 28, 2008 9:11 am

No, Antonio.

If you use the rc file I provided you, you can't disable the menu item.

Roberto Parisi

Roberto,

Ok, for the top menuitems you have to use the functions that I told you, this way:

@ 0, 0 button "Disable" size 100, 20 action TB_Disable( oWnd:hWnd, 110 ) pixel

tested and working fine

Roberto Parisi · Post by **Roberto Parisi** » Mon Jan 28, 2008 3:05 pm

Ok Antonio,
now it works, I needed to pass hWnd instead hMenu as first parameter in TB_Enable.

Many many thx.

Now I've troubles with GetKeyState() function, it returns always .F.

Regards,
Roberto Parisi

Roberto,

What value are you checking with GetKeyState() ?

Roberto Parisi · Post by **Roberto Parisi** » Thu Jan 31, 2008 10:05 am

Every value...

With the sample try to press SHIFT + TAB to go to previous control... it goes always to the next control forward.

Regards,
Roberto Parisi

#include "FWCE.ch"

function Main()

local oWnd, cText := Space( 50 ), cText1 := Space( 50 ), cText2 := Space( 50 )

DEFINE WINDOW oWnd TITLE "Test"

@ 0, 0 GET cText SIZE 200, 20 pixel

@ 30, 2 GET cText1 SIZE 200, 20 pixel

@ 60, 2 GET cText2 SIZE 200, 20 pixel

ACTIVATE WINDOW oWnd

return nil

Roberto,

Shift+Tab is working fine here on the WM2003 emulator.

Its going to the previous control

I email you my EXE
