Legend:

Working - Stable, most or all parts implemented.

Partially Implemented - Works, but has some features missing

In progress - Someone is working on this

Not Implemented - Nothing done, needs your help

Deprecated - Outdated, obsolete, usage not recommended for new projects

Current status of the various parts of Lazarus

Unit Item State Target Skills Responsible Comments
IDE TCollection Editor working 0.9.x FCL, RTTI, IDE - A generic TCollection editor for the various TCollections in the LCL/FCL.
IDE TActionList working 0.9.x - - -
IDE Doc Editor working - fpdoc - The doc editor will be an integrated fpDoc editor similar to fpde. It will be a process of its own, so that it can show help for dialogs as well. It should also be able to write help for packages.
IDE Export LFM as xml working - - - Load and save LFM files to XML.
IDE Icon Editor Roadmap in progress post 1.0 - - A simple icon editor with the ability to create lrs files. It will be a good example and can help newbies to create icons for their components.
LCL Borderspacing working 0.9.x - - for aligned controls
LCL Drag&Drop working - -
LCL Port to Darwin Power PC, Mac OS X working 0.9.x - - depends on FPC 1.9.5

LCL TCoolBar partially working, in progress post 1.0 LCL and anchoring Juha -
LCL TControlBar skeleton implementation to prevent errors in Delphi conversion, in progress post 1.0 LCL and anchoring Juha -
LCL TMaskEdit working - - Bart -
LCL TDirectoryTreeView not implemented - - - -
LCL Constrain maximization to specific area not implemented - winapi, gtk - When maximizing a window, the left, top, width and height can all be constrained to a specific rectangular area on the screen/desktop. After this is done, constrain the source editor and maybe other windows
