How to use a custom collection created from winrt::observable_vector_base
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Inside of my C++/WinRT project I am trying to use the example vector created here: https://docs.microsoft.com/en-us/windows/uwp/cpp-and-winrt-apis/collections
struct MyObservableVector :
implements<MyObservableVector, IObservableVector<float>, IVector<float>, IVectorView<float>, IIterable<float>>,
winrt::observable_vector_base<MyObservableVector, float>
{
auto& get_container() const noexcept
{
return m_values;
}
auto& get_container() noexcept
{
return m_values;
}
private:
std::vector<float> m_values{ 0.1f, 0.2f, 0.3f };
};
So for example, how would somebody use this vector inside the PhotoEditor demo app? (https://github.com/Microsoft/Windows-appsample-photo-editor)
Let's say you wanted to declare it as part of the Photo.idl Photo.h Photo.cpp ViewModel?

What's the usage of your vector here? The demo seems already contained the photo collection for binding.

The goal would be to call get_container() from MainPage.cpp to get the underlying vector.

use get_container to get the exist m_values does not make sense to photo project there. What's the value's usage?
