This project is a port of the clap-saw-demo VSTGUI example to have the same clap engine but use Dear IMGUI as the renderer for the clap gui. Currently it works on windows and macOS.
The project works by using the clap-imgui-support library which provides an interface between the imgui rendering setup and the clap gui interface.
That library hides most of the details, providing a DirectX12 render setup on windows and a Metal surface on macOS. Contributions from the linux community to make it work with SDL/OpenGL or another appropriate imgui backend would be welcomed!
To use the imgui, make an editor class which subclasses imgui_clap_editor such as
the ClapSawDemoEditor here
then implement the various mechanics to connect and render as shown in the cpp file.
Our CI pipeline shows the minimal build all paltforms which is
git clone --recurse-submodules https://github.com/free-audio/clap-saw-demo-imgui
cd clap-saw-demo-imgui
cmake -Bbuild -DCMAKE_BUILD_TYPE=Release
cmake --build build --config ReleaseTo build, you will need visual studio installed on windows, and XCode and CMake installed on macOS.
As with all cmake projects you can integrate with your various IDE of choice. For instance to use XCode directly you would do
cmake -B build -G Xcode
open build/clap-saw-demo-imgui.xcodeproj
