Dear Imgui Sample using OpenTK

This is a sample containing ImGui backend implementations for OpenTK using OpenGL. To get started copy the Backends/ folder into your project and do the steps described in Window.cs to get started with ImGui with OpenTK.

OpenTK 4

This version of the repo is targeting OpenTK 4. The minimum OpenGL version is 3.3.

Docking and multi-viewport support

The backend implementations in this version of the repo support docking and multi-viewport support. To enable these features add the corresponding configuration flag to ConfigFlags:

ImGuiIOPtr io = ImGui.GetIO();
io.ConfigFlags |= ImGuiConfigFlags.DockingEnable; // Enable docking
io.ConfigFlags |= ImGuiConfigFlags.ViewportsEnable; // Enable multi-viewports

Your OpenGL state will be untouched!

Previous versions of this repo required users to manually reset the OpenGL state that the ImGui renderer changed. This is no longer needed! The renderer resets the OpenGL state itself.

BadImageFormatexception

If you get the following error you might have to set your platform target to x86:

System.BadImageFormatException: 'An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)'

To do that, right click your project (all projects referencing ImGui.NET), click "Properties", click "Build", and change the "Platform target" to "x86".

To see more info and a potential fix you can take a look at issue #2.
