I hope this is the right place to ask questions about DirectXTK which aren't really about graphics, if not please let me know a better place.

Can anyone tell me why I cannot do this:

DirectX::SimpleMath::Rectangle rectangle = {...};
RECT rect = rectangle;

or

RECT rect = static_cast<RECT>(rectangle);

or

const RECT rect(m_textureRect);

despite Rectangle having the following operator RECT:

operator RECT() { RECT rct; rct.left = x; rct.top = y; rct.right = (x + width); rct.bottom = (y + height); return rct; }

VS2017 tells me:

 error C2440: 'initializing': cannot convert from 'const DirectX::SimpleMath::Rectangle' to 'const RECT'

Thanks in advance

operator RECT(){}

will not allow you to convert to a const RECT, you need a operator RECT() const {} for this (if i remember well)

Try just with

RECT rect = (RECT)rectangle;

should work.

(i'm going by memory, cannot test it now)

I thought the same and hacked a const in and it made no difference.  Doesn't really matter now - I've just added a conversion method to my Util class, however I was a bit stumped as to why it didn't work and wondered if it was a  well known issue in this forum.

Thanks for your reply.
