Imgui-knob

imgui-knob provides customizable knob widgets for Dear ImGui.

API

ImGui Bundle provides a direct translation of its API:

• C++ api
• Python api

Fork

ImGui Bundle uses a fork of imgui-knob, on the branch "imgui_bundle".

Full diff

Diff overview:

• Dpi aware (will be proposed via a PR)
• Use constant colors for the widget, since the way the original code reuses existing colors often leads to difficult to read knobs, especially with light themes.

This will not be proposed via a PR, since I'd rather explore a way to automatically select good colors depending on the theme's background color (taking inspiration from this snippet, which selects colors in the HSV color space and check that the contrast is sufficient)

imspinner

imspinner offers an extensive set of nice spinners for ImGui.

The folder external/immspinner/immspinner/ is a copy of imspinner, with some adaptations.

• C++ API
• Python API

imgui-toggle:

imgui_toggle provides a toggle switch widget for Dear ImGui.

• C++ API
• Python API

Fork

ImGui Bundle uses a fork of imgui-toggle on the imgui_bundle branch.
The modifications make imgui-toggle dpi aware, and will be proposed as a PR.

imgui-command-palette:

imgui-command-palette provide a "Visual Studio Code like" command palette.

ImGui Bundle uses a fork of imgui-command-palette, on the imgui branch, with no diff at the moment.

• C++ API
• Python API

ImFileDialog

ImFileDialog provides a file dialog for Dear ImGui, implemented using ImGui widgets.

ImGui Bundle uses a fork of ImFileDialog on the imgui_bundle branch.

This forks add some enhancements to the preview that were proposed as a PR.

As of now, ImFileDialog may have some rendering issues on windows with High Dpi screens.

• C++ API
• Python API

portable_file_dialogs

portable_file_dialogs provides a portable API to display native GUI dialogs windows, in a C++11 single-header. This does not depend on ImGui and has a rendering that is coherent with the user OS.

• C++ API
• Python API
