Hi,

I am trying to use wxwince with xrc. So basically I have a wxdialog
defined in a XRC and when I load it I get the following message
:SHCreateMenuBar failed

wxwidgets:

CApplicationDlg::CApplicationDlg( wxWindow* parent )
{
wxXmlResource::Get()->LoadDialog(this, parent, _("ApplicationDlg"));
}





It comes from here :
tbarwce.cpp:
wxwidgets:

bool wxToolMenuBar::MSWCreateToolbar(const wxPoint& WXUNUSED(pos), const
wxSize& WXUNUSED(size), wxMenuBar* menuBar)
{
....
#if defined(WINCE_WITHOUT_COMMANDBAR)
// Create the menubar.
SHMENUBARINFO mbi;

memset (&mbi, 0, sizeof (SHMENUBARINFO));
mbi.cbSize = sizeof (SHMENUBARINFO);
mbi.hwndParent = (HWND) GetParent()->GetHWND();
#ifdef __SMARTPHONE__
mbi.nToolBarId = 5002;
#else
mbi.nToolBarId = 5000;
#endif
mbi.nBmpId = 0;
mbi.cBmpImages = 0;
mbi.dwFlags = 0 ; // SHCMBF_EMPTYBAR;
mbi.hInstRes = wxGetInstance();

if (!SHCreateMenuBar(&mbi))
{
wxFAIL_MSG( _T("SHCreateMenuBar failed") );
return false;
}

SetHWND((WXHWND) mbi.hwndMB);
#else
HWND hWnd = CommandBar_Create(wxGetInstance(), (HWND)
GetParent()->GetHWND(), GetId());
SetHWND((WXHWND) hWnd);
#endif
....
}



Should i declare a toolbar in my xrc ?
Or do I need to do something different ?.
Or Maybe I should recompile wxwidgets with WINCE_WITHOUT_COMMANDBAR
[/syntax]

Where is declare this id of 5000 ?

Ok I have found from an old post this :
Unfortunatelly lack of menubar in WM5 is know limitation. The problem is
that we develop wxWinCE port mainly using WinCE 4(.NET). We do want to
upgrade sources to WM5 asap and we already investigated problem of
hidden menubar, see:
http://lists.wxwidgets.org/cgi-bin/ezmlm-cgi?5:sss:71710
Since there is not enough manpower among developers, improving wxWinCE
port to WM5 is one of our selections for Google Summer of Code, see:
http://wxforum.shadonet.com/viewtopic.php?p=36278


Ok I understand but why when we create a dialog, we should also create a
menubar.
This is two different operations. So if there is some developper around
here, I would have some feedback to give to improve the wince port.


1)when you download wxwidgets-2.8.0.zip, the setup.h for the wince port
is MISSING. We have to get it from CVS (not very handy).

2)You provide embedded visual project but it doesn't work due to the
number of files. it always hang and cpu is 100%.
Only Visual studio 2005 is able to support it, so you should provide VS
2005 projecnd and workspace(if you like mine).

3)Now wince5 compiler support exceptions so you can use it

4)Files in the zip format(supposed to be used by windows developper) are
in unix format and Visual do not know how to handle this for project.

I am ready to help to improve the port but I won't have a time to submit
my fixes through CVS or patch.
I can only post some code here...

For now I would remove CreateToolbar from wxDialog::Create

bool wxDialog::Create(wxWindow *parent,
wxWindowID id,
const wxString& title,
const wxPoint& pos,
const wxSize& size,
long style,
const wxString& name)
{
....
#if defined(__SMARTPHONE__) && defined(__WXWINCE__)
SetLeftMenu(wxID_OK, _("OK"));
#endif
#if wxUSE_TOOLBAR && defined(__POCKETPC__)
CreateToolBar();
#endif
}

Besides on Smartphone you may want to have something different from OK
on the left menu.
You can always create the menubar in the
MyDialog::OnInitDialogFunction(wxInitDialogEvent& event).

Am I wrong ?

tell it to my boss. "No problem boss I just need to wait half an hour
to be able to click"

VZ> > No idea to be honest but I don't understand how creating the

What I don't understand first is where does this id of 5000 come from ?
Secondly why are you trying to create a menubar in the create dialog method?
I would have done something like that in MFC:


// in a dialog
void CApplicationDlg::OnInitDialog()
{
//The first way. Using CCeCommandBar class.
CCeCommandBar *pCommandBar = (CCeCommandBar*)m_pWndEmptyCB;
pCommandBar->InsertMenuBar(IDR_MENUBAR);

/* //The second way. Using SHCreateMenuBar function.
SHMENUBARINFO info;
info.cbSize = sizeof(info);
info.hwndParent = m_hWnd;
info.dwFlags = 0;
info.nToolBarId = IDR_MENUBAR;
info.hInstRes = ::AfxGetInstanceHandle();
info.nBmpId = 0; info.cBmpImages = 0;
SHCreateMenuBar(&info); */
}

So could we imagine something similar under wxwidgets ?
So I would'nt try to create automatically a menubar but I would let it
to developper choice.

> First, let me say that I didn't write this code so I had no idea
about this neither. So I actually looked up SHCreateMenuBar() in MSDN
and learnt that nToolBarId was a resource id. Armed with this
information, I opened include/wx/msw/wince/wince.rc and found that there
is indeed a menu with this id there. Of course, using hard coded 5000
instead of a symbolic constant is a bad idea. But OTOH it would surely
have taken less time to find what does this constant stand for than to
send a message here and waitfor my reply.

Ok you are right, I am bit lazy. I admit it.
Besides I have already searched for it but since I am used to MFC I was
looking for a .h and not directly in .rc.

Anyway I will investigate why it fails and keep you informed and maybe
if I am in a good day I will post a patch.

Hey But you are working for a french company not very far from me!
About my problem I suppose it comes from the fact I need to include
wince.rc in my project.
I will test tomorrow.
