tharsis-dimgui 0.1.10

tharsis-dimgui

This is a (temporary?) fork of dimgui, the D port of the [imgui] OpenGL GUI library.

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

dimgui is an [immediate-mode] GUI library.

Main differences from dimgui

• Simple text input widget
• Minor bugfixes
• Depends on Derelict for OpenGL instead of glad-drey.

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
