We have made a hand-written C wrapper on top of the imgui_toggle library. To use it, add the imgui_toggle.h header file in your include path.

The cimgui_toggles.h header looks like this:

typedef enum ImGui_ToggleFlags_
{
    CImGuiToggleFlags_None                   = 0,
    CImGuiToggleFlags_Animated               = 1 << 0, // The toggle's knob should be animated.
                                                       // Bits 1-2 reserved.
    CImGuiToggleFlags_BorderedFrame          = 1 << 3, // The toggle should have a border drawn on the frame.
    CImGuiToggleFlags_BorderedKnob           = 1 << 4, // The toggle should have a border drawn on the knob.
    CImGuiToggleFlags_ShadowedFrame          = 1 << 5, // The toggle should have a shadow drawn under the frame.
    CImGuiToggleFlags_ShadowedKnob           = 1 << 6, // The toggle should have a shadow drawn under the knob.
                                                       // Bit 7 reserved.
    CImGuiToggleFlags_A11y                   = 1 << 8, // The toggle should draw on and off glyphs to help indicate its state.
    CImGuiToggleFlags_Bordered               = CImGuiToggleFlags_BorderedFrame | CImGuiToggleFlags_BorderedKnob, // Shorthand for bordered frame and knob.
    CImGuiToggleFlags_Shadowed               = CImGuiToggleFlags_ShadowedFrame | CImGuiToggleFlags_ShadowedKnob, // Shorthand for shadowed frame and knob.
    CImGuiToggleFlags_Default                = CImGuiToggleFlags_None, // The default flags used when no ImGuiToggleFlags_ are specified.
} ImGui_ToggleFlags_;

typedef enum ImGui_Toggle_A11yStyle_
{
    CImGuiToggleA11yStyle_Label,     // A11y glyphs draw as text labels.
    CImGuiToggleA11yStyle_Glyph,     // A11y glyphs draw as power-icon style "I/O" glyphs.
    CImGuiToggleA11yStyle_Dot,       // A11y glyphs draw as a small dot that can be colored separately from the frame.
    CImGuiToggleA11yStyle_Default    = CImGuiToggleA11yStyle_Label,
} ImGui_ToggleA11yStyle_;

typedef struct ImGui_ImOffsetRect
{
    union
    {
        float offsets[4];
        struct
        {
            float top;
            float left;
            float bottom;
            float right;
        };
    };
} ImGui_ImOffsetRect;

typedef struct ImGui_TogglePalette
{
    CImXVec4 knob;
    CImXVec4 knobHover;
    CImXVec4 frame;
    CImXVec4 frameHover;
    CImXVec4 frameBorder;
    CImXVec4 frameShadow;
    CImXVec4 knobBorder;
    CImXVec4 knobShadow;
    CImXVec4 A11yGlyph;
} ImGui_TogglePalette;

typedef struct ImGui_ToggleStateConfig
{
    float frameBorderThickness;
    float frameShadowThickness;
    float knobBorderThickness;
    float knobShadowThickness;
    const char* label;
    ImGui_ImOffsetRect knobInset;
    CImXVec2 knobOffset;
    const ImGui_TogglePalette* palette;
} ImGui_ToggleStateConfig;

typedef struct ImGui_ToggleConfig
{
    ImGui_ToggleFlags flags;
    ImGui_Toggle_A11yStyle A11yStyle;
    float animationDuration;
    float frameRounding;
    float knobRounding;
    float widthRatio;
    CImXVec2 size;
    ImGui_ToggleStateConfig on;
    ImGui_ToggleStateConfig off;
} ImGui_ToggleConfig;
void ImGui_UnionPalette(ImGui_TogglePalette* target, const ImGui_TogglePalette* candidate, const CImXVec4* colors, bool v);
void ImGui_BlendPalettes(ImGui_TogglePalette* result, const ImGui_TogglePalette* a, const ImGui_TogglePalette* b, float blend_amount);

bool ImGui_Toggle(const char* label, bool* v, ImGui_ToggleFlags flags, float animation_duration, float frame_rounding, float knob_rounding, const CImXVec2* size);

As you can see, we have implemented custom compatibility structs that are designed to bind 1:1 to the imgui_toggle library. The only differences are:

1. All structures in the ImGui namespace are prefixed with ImGui_.
2. Default arguments are missing because they’re not supported in C. You can use the comments in the header file for reference.
3. All enum members are prefixed with C in order to avoid conflicts with the normal imgui_toggle library.
