Features

EasyImGui allows you to Create your GUI with ImGui, without having to configure anything, you don't need any additional knowledge.

You just need to install EasyImGui from NuGet and that's it! .

Note:

EasyImGui uses DearImGuiSharp, so any question related to ImGui should be asked in its official Reposttory: https://github.com/Sewer56/DearImguiSharp

If within your ImGui code you launch controls that block the Main UI, such as OpenFileDialog or MessageBox.Show, it will cause your application to fail, this is easy to solve, Simply do everything Asynchronously, Without Dialogs ".ShowDialog()"

Example

DX9 Overlay + Imgui Window.

  Overlay OverlayWindow = new Overlay() { EnableDrag = true, ResizableBorders = true,  Fix_WM_NCLBUTTONDBLCLK = true };

 //SingleImguiWindow.ImGuiWindowFlagsEx = DearImguiSharp.ImGuiWindowFlags.NoTitleBar;
 OverlayWindow.OnImGuiReady += (object sender, bool Status) =>
 {

     if (Status)
     {
         OverlayWindow.Imgui.ConfigContex += delegate {

             //DearImguiSharp.ImGui.StyleColorsLight(null);

             var style = ImGui.GetStyle();

             ImVec4[] styleColors = style.Colors;
             styleColors[(int)ImGuiCol.CheckMark].W = 1.0f;
             styleColors[(int)ImGuiCol.CheckMark].X = 1.0f;
             styleColors[(int)ImGuiCol.CheckMark].Y = 1.0f;
             styleColors[(int)ImGuiCol.CheckMark].Z = 1.0f;

             styleColors[(int)ImGuiCol.FrameBg].W = 0.0f;
             styleColors[(int)ImGuiCol.FrameBg].X = 0.0f;
             styleColors[(int)ImGuiCol.FrameBg].Y = 0.0f;
             styleColors[(int)ImGuiCol.FrameBg].Z = 0.0f;

             style.WindowRounding = 5.0f;
             style.FrameRounding = 5.0f;
             style.FrameBorderSize = 1.0f;



             //OverlayWindow.Imgui.IO.ConfigFlags |= (int)ImGuiConfigFlags.ViewportsEnable;

             return true;
         };


         bool DrawImguiMenu = true;

         SharpDX.Direct3D9.Device device = OverlayWindow.D3DDevice;

         OverlayWindow.Imgui.Render += delegate {


             if (DrawImguiMenu == false) { OverlayWindow.Close();  return true; }

             if (OverlayWindow.Imgui.Imgui_Ini == true && OverlayWindow.Imgui.IO != null)
             {

                 // Overlay Dragger
                 bool IsFocusOnMainImguiWindow = (Form.ActiveForm == OverlayWindow); // Old : DearImguiSharp.ImGui.IsWindowFocused((int)DearImguiSharp.ImGuiFocusedFlags.RootWindow);
                 if (IsFocusOnMainImguiWindow == true) { InputHook.Universal(OverlayWindow.Imgui.IO); }
                 OverlayWindow.EnableDrag = (DearImguiSharp.ImGui.IsAnyItemActive() == true) ? false : IsFocusOnMainImguiWindow;

                 DearImguiSharp.ImGui.SetNextWindowPos(new ImVec2 { X = 0, Y = 0 }, 0, new ImVec2 { X = 0, Y = 0 });
                 DearImguiSharp.ImGui.SetNextWindowSize(new ImVec2() { X = OverlayWindow.ClientSize.Width , Y = OverlayWindow.ClientSize.Height  }, 0);

                 DearImguiSharp.ImGui.Begin(OverlayWindow.Text, ref DrawImguiMenu, 0); // (int)ImGuiWindowFlags.NoResize | (int)ImGuiWindowFlags.NoMove | (int)ImGuiWindowFlags.NoCollapse | (int)ImGuiWindowFlags.NoBringToFrontOnFocus

                 if (DearImguiSharp.ImGui.Button("Message", new DearImguiSharp.ImVec2() { X = OverlayWindow.ClientSize.Width - 15, Y = 20 }))
                 {
                     Task.Run(() =>
                     {
                         MessageBox.Show("Hello World!");
                     });
                 }

                 if (DearImguiSharp.ImGui.Button("Exit", new DearImguiSharp.ImVec2() { X = OverlayWindow.ClientSize.Width - 15, Y = 20 }))
                     OverlayWindow.Close();

             }

             return true;
         };

     }
 };

 try { Application.Run(OverlayWindow); } catch { Environment.Exit(0); }
