Development

Building Platemaker from source and contributing to it.

Scope. These pages cover the Qt GUI. libplatemaker appears only where the GUI needs it — for the library's own build instructions, data models and CLI, see the PlateMaker repository.

Full setup: Environment.

Pages in this section

Page	Covers
Environment	Toolchain install, Qt Creator kits
Building	Configuring, linking libplatemaker, running
Architecture	How the code is organised and why
Main window	The shell, the project view, application state, thumbnails, threads
Workflows	Open, create, render, cancel, templates, canvas profiles, step by step
Releasing	Versioning, installer, publishing a release
Contributing	Branching, style, pull requests
Windows hardening	The DLL search path, and what is deferred

Strip editor and the tool framework

A separate group of pages specifies the strip editor's tool framework — how tools, objects and property groups relate, and which panel is allowed to talk about which.

Page	Covers
Tool framework	Vocabulary, layers, the regions
Code map	Which folder holds which region, what may include what
Shell	The dock, rail, columns, cursor, colour pair, rendering, the grade
Objects	Bubbles, tails, placement, presets, imported artwork
Property groups	The structs, ownership, roles, the write contract, the tests
Object state and tool options	What each panel contains, presets and their badge
History and undo	One undo history per project, and how a step shows itself
Advisories and badges	Status-bar advisories, widgets/badge/ — application-wide
Inputs and anchoring	Replacing a page, unanchored objects, the render gate

Workspace folder ownership

Page	Covers
Workspace folder ownership	One workspace per folder, the lock and takeover, Save As collecting files, the sweep at open, missing-font healing, the workspace's own fonts, the export/open package

Where the library documentation lives

These pages cover the GUI. For the library itself, the PlateMaker repository has:

Document	Covers
its wiki	The domain model, the pipeline, profile matching and its error semantics
docs/CHEATSHEET.md	Copy-paste build commands for every preset
docs/CODING_STYLE.md	Naming, Doxygen format and file layout — shared by both projects
docs/TODO.md	Planned library work, including anything the GUI is waiting on

Keeping this wiki in sync

The Development pages (this one, the strip-editor series, Advisories, Anchoring, Workspace folder ownership) are synced against the application's source, not against the public GUI release — they describe unreleased work in progress. When you next need to bring them up to date, diff from the commit named in the footer of every page (also below) rather than from the last tagged release.

Last synced to Platemaker GUI commit 1296c1c, 2026-10-01.

Status of this project

There is no build/test CI — nothing compiles or exercises your change on push. The GUI has a small unit-test target covering the property model (tests/gui-unit-tests/, off by default — see Property groups); everything involving a window is verified manually. The project is also not currently seeking contributors, which is not a rule against contributions — see Contributing before starting work you would like merged, and Extending the strip editor before extending the strip editor.
