Regarding Enabling/Disableing Menu

 

 

Our application was developed using Code jock 4.2 version. Now we are trying to implement code jock 10.4.2 in our application.

 

In our older version of application which is using code jock 4.2, we were using "ON_WM_INITMENUPOPUP()" command, whose definition is below:

 

 

 

 

 

   CMenu* pPopupMenu ----- CTempMenu

 

 

 

 

   // Create MenuBar using CXTPMenuBar*
   m_wndMenuBar = pCommandBars->SetMenu(_T("Menu Bar"), IDR_MAINFRAME);

 

the values what we are getting for above mention 3 paramenters

 

 

Thanks for your reply.

 

I had trying with the OnInitCommandsPopup() given in Notification sample.

 

I trapped "ON_XTP_INITCOMMANDSPOPUP()" i.e. OnInitCommandsPopup() function.

 

 

   //Get Menu Handle 

 

 

 

 

Our application follows standard View/Document architecture, We do not have handler for cut,copy,paste and find in our OLDER version of application as well as NEW version of Application.

 

we are just using "ON_WM_INITMENUPOPUP()" message in older version of our application.

 

For above mentioned message we are having Handler

 

Hi Oleg,

 

Thanks you very much for your seggestions and help.

 

Yes I do understand it is not good idea to implement WM_INITMENUPOPUP, but as we are following design patterns and handling all the enabling/disabling menu item in a single class, which required nIndex, which we were getting in OnInitMenuPopup() function's 2nd parapameter.

 

Is there any way to get nIndex (determine on which menu user clicks), so that I have to make few changes with changing the desgin pattern.

 

 

 

Thanks for your great suggestion.

When I placed the code what you sent it giving the error below:

 

 

Then I searched for SetEnable() in the help, and I found SetEnabled() in CXTPControl class.

 

 

void CMainFrame::OnInitCommandsPopup(CXTPPopupBar* pCommandBar)
{

   CXTPControl* pCommandNew = pCommandBar->GetControls()->FindControl(xtpControlButton, ID_EDIT_CUT, TRUE, FALSE);
 

//CXTPControl* pCommandNew = pCommandBar->GetControls()->FindControl(xtpControlPopup, ID_EDIT_CUT, TRUE, FALSE);

 int nCount = pCommandBar->GetControls()->GetCount();

 

 for (int i = 0; i < nCount; i++)
 {
   if (pCommandBar->GetControl(i)->GetID() == ID_EDIT_CUT)
   pCommandNew->SetEnabled(FALSE);
   //[Comment out due to error mentioned above]

   //pCommandBar->GetControl(i)->SetEnable(FALSE);
   }

 }

 

What need to be done for this Oleg????

 

Thanks,

KumarCJ

void CMainFrame::OnInitCommandsPopup(CXTPPopupBar* pCommandBar)
{

  int nCount = pCommandBar->GetControls()->GetCount();

 

 for (int i = 0; i < nCount; i++)
 {

CXTPControl* pCommandNew =  pCommandBar->GetControl(i)
   if (pCommandNew->GetID() == ID_EDIT_CUT)
   {

          pCommandNew->SetEnabled(FALSE);

         pCommandBarNew->SetFlags(xtpFlagManualUpdate);
    }

   }

 }

 

Also check "Samples\CommandBars\ActionsSample" sample - if you don't want update handlers, you can use actions

 

pCommandBars->GetActions()->FindAction(ID_EDIT_CUT)->SetEnabled(FALSE);

 

again - don't use OnInitCommandBarsPopup for changing state - its very bad design. There is no pattern for such design.
