C++ compiler errors in xamltypeinfo.g.cpp
- by Richard Banks
I must be missing something obvious but I'm not sure what.
I've created a blank C++ metro app and I've just added a model that I will bind to in my UI however I'm getting a range of compiler warnings related to xamltypeinfo.g.cpp and I'm not sure what I've missed.
My header file looks like this:
#pragma once
#include "pch.h"
#include "MyColor.h"
using namespace Platform;
namespace CppDataBinding
{
[Windows::UI::Xaml::Data::Bindable]
public ref class MyColor sealed : Windows::UI::Xaml::Data::INotifyPropertyChanged
{
public:
MyColor();
~MyColor();
virtual event Windows::UI::Xaml::Data::PropertyChangedEventHandler^ PropertyChanged;
property Platform::String^ RedValue
{
Platform::String^ get()
{
return _redValue;
}
void set(Platform::String^ value)
{
_redValue = value;
RaisePropertyChanged("RedValue");
}
}
protected:
void RaisePropertyChanged(Platform::String^ name);
private:
Platform::String^ _redValue;
};
}
and my cpp file looks like this:
#include "pch.h"
#include "MyColor.h"
using namespace CppDataBinding;
MyColor::MyColor()
{
}
MyColor::~MyColor()
{
}
void MyColor::RaisePropertyChanged(Platform::String^ name)
{
if (PropertyChanged != nullptr)
{
PropertyChanged(this, ref new Windows::UI::Xaml::Data::PropertyChangedEventArgs(name));
}
}
Nothing too tricky, but when I compile I get errors in xamltypeinfo.g.cpp indicating that MyColor is not defined in CppDataBinding.
The relevant generated code looks like this:
if (typeName == "CppDataBinding.MyColor")
{
userType = ref new XamlUserType(this, typeName, GetXamlTypeByName("Object"));
userType->Activator = ref new XamlTypeInfo::InfoProvider::Activator(
[]() -> Platform::Object^
{
return ref new CppDataBinding::MyColor();
});
userType->AddMemberName("RedValue", "CppDataBinding.MyColor.RedValue");
userType->SetIsBindable();
xamlType = userType;
}
If I remove the Bindable attribute from MyColor the code compiles.
Can someone tell me what blindingly obvious thing I've missed so I can give myself a facepalm and fix the problem?
