Hi all,
My application used a user-defined number of cameras (minimum 1). The user can pick from a commandbar the active camera.
To populate the commandbar, i use:
BOOST_FOREACH(ICamera* camera, cameras->Collection()) {
CXTPControl* pCameraItem = pControls->Add(xtpControlButton, ID_CAMERA);
pCameraItem->SetCaption( camera->Name().c_str() );
pCameraItem->SetChecked( camera == cameras->Active() );
}
The listen to the commands, i use:
ON_COMMAND(ID_CAMERA, OnCamera)
and
void CPyroView::OnCamera()
{
// what camera is being picked?
}
Question: all the controls in the commandbar have the same id (ID_CAMERA) - in OnCamera i can't make the distinction between what camera is picked.
What is the correct method to use, when the amount of camera's is unknown (iow ON_COMMAND_RANGE cant be used)
Thanks
Bart

Hi,
Add
pCameraItem->SetTag( iIndex)
Remove ON_COMMAND and insert this line
ON_XTP_EXECUTE(ID_FILE_RECENTPROJECTS, OnCamera)
void CPyroView::OnCamera(NMHDR *pNMHDR,LRESULT *pResult)
{
CXTPControl *pControl = ((NMXTPCONTROL *)pNMHDR)->pControl;
if (pControl)
{
DWORD_PTR myIndex = pControl->GetTag();
// do yours
}
}

Or
pCameraItem->SetTag( (DWORD_PTR) camera );
ICamera* camera = (ICamera*) pControl->GetTag();

Also can use
CXTPControl *CPyroView::GetControl(CCmdUI *pCmdUI)
{
if (!pCmdUI->m_pOther)
return NULL;
return ((CXTPCommandBar*)pCmdUI->m_pOther)->GetControl(pCmdUI->m_nIndex);
}
void CPyroView::OnUpdateCamera(CCmdUI *pCmdUI)
{
if (m_dwMenuLock & ML_ANY)
pCmdUI->Enable(FALSE);
else
{
CXTPControl* pControl = GetControl(pCmdUI);
if (pControl)
{
ICamera* camera = (ICamera*) pControl->GetTag();
pCmdUI->SetCheck( (camera->Active()) );
}
else
pCmdUI->Enable(FALSE);
}
}

Thank you Kimmy - i'm trying the latter, but bump into undefined "m_dwMenuLock" & "ML_ANY". I searched the library, but could find any reference to it.
Will the last proposal also be capable of checking the active camera? (only active camera is checked, the other arent)
Thanks again for looking inito this

(Jimmy - sorry for misspelling your name)
(I commented m_dwMenuLock & ML_ANY)
I got this to work:
//---------------------------------------------------------------------------
//
//---------------------------------------------------------------------------
//
void
CPyroView::OnCamera(NMHDR *pNMHDR,LRESULT *pResult)
{
CXTPControl *pControl = ((NMXTPCONTROL *)pNMHDR)->pControl;
if (pControl)
{
ICamera* camera = (ICamera*)pControl->GetTag();
assert(camera);
camera->Activate();
}
}
//---------------------------------------------------------------------------
//
//---------------------------------------------------------------------------
//
CXTPControl* CPyroView::GetControl(CCmdUI *pCmdUI)
{
if (!pCmdUI->m_pOther)
return NULL;
return ((CXTPCommandBar*)pCmdUI->m_pOther)->GetControl(pCmdUI->m_nIndex);
}
//---------------------------------------------------------------------------
//
//---------------------------------------------------------------------------
//
void CPyroView::OnUpdateCamera(CCmdUI *pCmdUI)
{
//if (m_dwMenuLock & ML_ANY)
// pCmdUI->Enable(FALSE);
//else
{
CXTPControl* pControl = GetControl(pCmdUI);
if (pControl)
{
ICamera* camera = (ICamera*) pControl->GetTag();
ASSERT(camera);
pCmdUI->SetCheck(camera->IsActive());
pCmdUI->Enable(camera != NULL);
}
else
pCmdUI->Enable(FALSE);
}
}
Thanks!
