Relationship to MEDM

QtEDM reads and writes the core MEDM ADL format and supports additional QtEDM-only extensions. Review the compatibility differences and current limitations before migrating or editing a display, especially one with backslash escapes or a custom color map. The primary toolkit differences are:

• Modern GUI toolkit – Qt6 or Qt5 instead of Motif/X11
• Cross-platform runtime – Native Linux, macOS, and Windows builds
• Improved rendering – Better font handling and anti-aliased graphics
• Active development – Ongoing maintenance alongside the legacy MEDM

Both MEDM and QtEDM are built from the same source repository and share the same overall display-model lineage. This supports reuse of existing displays, subject to the documented differences and limitations; it does not guarantee lossless interchange of every MEDM display.
