This is a port/adaptation of imgui-rs-knobs, for C++. This port contains modifications which break compatibility with the original Rust implementation.

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

TODO: Add image of examples of these styles in practice

static float value = 0;

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

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

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

button_style determines the visual look of the clickable part of the knob. Available button styles are: ImGuiKnobButtonStyle_None, ImGuiKnobButtonStyle_Blank, ImGuiKnobButtonStyle_Tick, ImGuiKnobButtonStyle_Dot.

border_style determines the visual look of the outer track of the knob. Available border styles are: ImGuiKnobBorderStyle_None, ImGuiKnobBorderStyle_Ticks, ImGuiKnobBorderStyle_WiperDot, ImGuiKnobBorderStyle_WiperTick.

fill_style determines how the border specified above is filled. This only applies to the wiper styles. Available fill styles are: ImGuiKnobFillStyle_NoFill, ImGuiKnobFillStyle_LeftFill, ImGuiKnobFillStyle_CenterFill, ImGuiKnobFillStyle_RightFill.

• 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).

You can specify a size with the size argument, don't use the global font scaling thing anymore

Steps determines the number of steps draw, it is only used for the ImGuiKnobBorderStyle_Ticks variant to specify the number of ticks to draw.
