i'm not familiar at all with the mingw-w64 headers, indeed. I'm just
guessing stuff by comparing what is in d2d1.h,  d2d1_1.h and the
d2d1_1.h generated with widl.

Question:

I have added ID2D1Properties C API (see attached diff). In d2d1.h,
STDMETHOD_ was used for the functions in the Vtbl struct. Should I do
the same ?

thank you

You may clone the mingw-w64 repo, commit your changes locally, then use `git 
format-patch  [-o
]` to create patches, then send them to this mailing 
list. Patches can be
opened with an email client directly, or sent as attachments. Your contribution 
will be appreciated.


For example, to export the last 3 commits in the current branch to the current 
directory, use

git format-patch HEAD~3

To export all commits since `origin/master`, use

git format-patch origin/master

To export a specific commit, use

git format-patch -1 

To export only the last commit in the current branch, use

git format-patch HEAD~  # alternative 1
git format-patch -1 HEAD# alternative 2

i can add what is missing part by part in d2d1.h. What is the standard
procedure ? if there is a github mirror and if PR are a possible way
to provide patches, i can do that

There are multiple problems with C++ constructs used in d2d1.h that are 
not possible in IDL files and we'd need solutions to those first. I'm 
not convinced if it's the right thing to do for that particular header.



For the time being, I'd suggest to extend the existing header.

i also have an error that i do not understand

when i use

ID2D1Factory1_CreateDevice(***);

the compiler says that

d2d.c:12:60: error: 'ID2D1FactoryVtbl' has no member named 'CreateDevice'
   12 | #define ID2D1Factory1_CreateDevice(this,A,B)
(this)->lpVtbl->CreateDevice(this,A,B)
  |^~
d2d.c:301:16: note: in expansion of macro 'ID2D1Factory1_CreateDevice'
  301 | if (FAILED(ID2D1Factory1_CreateDevice(factory,
dxgi_device, &d2d_device)))
  |^~

i don't understand why. I've properly defined

#define D2D_USE_C_DEFINITIONS
#define _WIN32_WINNT 0x0A00

before inclusion of d2d header

any idea why ?

I would like to avoid the manual editing of d2d1 header files. I tried
to import d2d1.idl and d2d1_1.idl from wine. widl produces the
corresponding headers file without any errors. But while compiling
crt, it conflicts with `namespace D2D1` in d2d1helper.h as it is in
C++ realm. One thing can be done but I am not sure about it:
0. Sync mingw-w64's d2d1_1.h with wine's d2d1_1.idl.
1. Import d2d1.idl and d2d1_1.idl from wine.
2. Generate header for d2d1_1.idl but NOT for d2d1.h.

for example, adding in d2d1_1.h around line 1054 :


#define ID2D1Device_CreateDeviceContext(this,A,B)

i know how to use fgrep...

what is missing is the classic C API, like (in d2d1_1.h) :

ID2D1Factory1_QueryInterface

that is, a define that call the method from the "virtual table" :

#define ID2D1Factory1_QueryInterface(this,A,B)
(this)->lpVtbl->Base.Base.QueryInterface((IUnknown *)(this),A,B)

it calls QueryInterface from the IUnknownVtbl structure, through
Base.Base in the define above

These are those defines that are missing.

Same for BeginDraw and EndDraw
