Bug Description

Tried to run ExampleGLFWOpenGL3 imgui window background color is red.
When i comment out this line the colors are as epxected:

Hexa.NET.ImGui/Examples/ExampleGLFWOpenGL3/Program.cs

Line 61 in dc79fe1

style.Colors[(int)ImGuiCol.WindowBg].W = 1.0f;

So the W component of the Vector4 maps to red isntead of the expected alpha.

Steps to Reproduce

Run ExampleGLFWOpenGL3.
Observe red window background.

Expected Behavior

W maps to alpha. Window color is opaque but with the color matches the default "Dark" style.

Code Sample

Platform

Windows

.NET Version

Hi, that might be a bug, i will investigate further in the future, but you shouldn't use the examples in main branch anyways checkout a version tag or use the version branches, those are more stable and don't include half updated code.

I am also experiencing this issue on a custom ImGui Backend.

Figured it out - the issue not related to the actual treatment of colors, but the structure of the ImGuiStyle struct being incorrect on the C# side, most likely due to Cimgui being outdated.
