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. -

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.
Steps
Steps determines the number of steps draw, it is only used for the ImGuiKnobVariant_Stepped
variant.
