Some errors with ImVec2 + math while coding a custom checkbox.

[Smellon69]

Version/Branch of Dear ImGui:

Version: DX9
Branch: It's just the latest version with all the essential files.

Back-end/Renderer/Compiler/OS

Back-ends: imgui_impl_dx9.cpp + imgui_impl_win32.cpp
Compiler: Visual Studio 2022 Community
Operating System: Revision OS Windows 11 Pro

My Issue/Question:

So I am adding a custom checkbox and here is the line of code causing me all the trouble:
const ImRect bb(pos, pos + pos);
The error is:
No operator "+" matches these operands: operand types are: ImVec2 + ImVec2

Screenshots/Video

Standalone, minimal, complete and verifiable example: (see #2261)

// Here's some code anyone can copy and paste to reproduce your issue
const ImRect bb(pos, pos + pos);

See the definition of ImVec2 we don’t define maths operators for it by default, as they could collide with your own maths operators in the case you setup ImVec2 to auto-cast to your own math types.

You can import our maths operator by using:

#define IMGUI_DEFINE_MATH_OPERATORS
#include "imgui.h"

You can import our maths operator by using:

#define IMGUI_DEFINE_MATH_OPERATORS
#include "imgui_internal.h"

hello i have the same error even if i define the :

#define IMGUI_DEFINE_MATH_OPERATORS
#include "imgui_internal.h"
still have this error
