ImGui Knobs

This is a port/adaptation of imgui-rs-knobs, for C++.

Usage

Add imgui-knobs.cpp and imgui-knobs.h to your project and include imgui-knobs.h in some source file.

static float value = 0;

if (ImGuiKnobs::Knob("Volume", &value, -6.0f, 6.0f, 0.1f, "%.1fdB", ImGuiKnobVariant_Tick)) {
    // value was changed
}

Draw knobs using either Knob or KnobInt. The API is:

bool ImGuiKnobs::Knob(label, *value, min, max, [speed, format, variant, size, flags, steps])
bool ImGuiKnobs::KnobInt(label, *value, min, max, [speed, format, variant, size, flags, steps])

Variants

variant determines the visual look of the knob. Available variants are: ImGuiKnobVariant_Tick, ImGuiKnobVariant_Dot, ImGuiKnobVariant_Wiper, ImGuiKnobVariant_WiperOnly, ImGuiKnobVariant_WiperDot, ImGuiKnobVariant_Stepped, ImGuiKnobVariant_Space.

Flags

ImGuiKnobFlags_NoTitle: Hide the top title.
ImGuiKnobFlags_NoInput: Hide the bottom drag input.
ImGuiKnobFlags_ValueTooltip: Show a tooltip with the current value on hover.
ImGuiKnobFlags_DragHorizontal: Use horizontal dragging (default is vertical).

Size

You can specify a size given as the width of the knob (will be scaled according to ImGui's FontGlobalScale). Default (0) will use 4x line height.
