dimgui

dimgui

This is a D port of the imgui OpenGL GUI library.

dimgui is an immediate-mode GUI library.

Homepage: https://github.com/d-gamedev-team/dimgui

Supported compilers

Currently requires DMD v2.071.0, not tested with other compilers, and not frequently tested on Windows.

Examples

Use dub to build and run the example project:

# Shows a nice demo of the various UI elements.
$ dub run dimgui:demo

# Shows how to properly handle memory management.
$ dub run dimgui:memory

Note: You will need to install the glfw shared library in order to run the example.

Real-world examples

dimgui is used in the following projects:

  • dbox - The 2D physics library uses dimgui for its interactive test-suite.

Documentation

The public API is available in the imgui.api module.

Memory Management

For efficiency reasons imgui will batch all commands and will render the current frame once imguiRender is called. Calls to UI-defining functions such as imguiLabel will store a reference to the passed-in string and will not draw the string immediately.

This means you should not pass in memory allocated on the stack unless you can guarantee that:

  • The memory on the stack will live up to the point imguiRender is called.
  • The memory passed to the UI-defining functions is unique for each call.

An example of both improper and proper memory management is shown in the memory example.

Building dimgui as a static library

Run dub alone in the root project directory to build dimgui as a static library:

$ dub
