The pre-run install wrote the bundled INI to cwd, and the
_install_default_layout_if_empty helper applies it via
imgui.load_ini_settings_from_memory() when cwd is empty. But the
GUI was rendering all panels as floating windows at default position
(60, 60) with no DockId, despite the bundled INI having a full
[Docking][Data] block with DockSpace + DockNodes + per-window DockIds.
Root cause analysis (via imgui.save_ini_settings_to_memory() at runtime):
1. With default_imgui_window_type=provide_full_screen_dock_space:
HelloImGui creates its own DockSpace at runtime, overriding the INI's
DockSpace settings. The DockSpace ID matches (0xAFC85805) but the
Split/X and child DockNodes from the bundled INI are discarded.
Runtime INI shows: 'DockSpace ID=0xAFC85805 Window=0x079D3A04 Pos=0,28
Size=1666,1172 CentralNode=1' (no DockNodes, no DockIds honored).
2. The pre-run install writes the INI to disk, but HelloImGui's
load_user_pref runs BEFORE post_init, so even a perfect on-disk
INI doesn't get re-applied to the current session's dock state
unless we call imgui.load_ini_settings_from_memory() after the
first frame.
Two-part fix:
A. src/gui_2.py line 678: change default_imgui_window_type from
'provide_full_screen_dock_space' to 'no_default_window'. Without
the auto-created DockSpace, HelloImGui honors the INI's full
docking tree structure.
B. src/gui_2.py _post_init (line 575): always call
imgui.load_ini_settings_from_memory() after _install_default_layout
runs, regardless of whether the cwd INI was empty. This re-applies
the bundled INI to the live session after the first frame is
rendered, so the panels are docked correctly on the current launch.
Layouts/default.ini: replace the simple 'DockSpace + 2 direct
DockNode children' structure (silently ignored by HelloImGui) with
the user's working nested DockNode tree (5-level deep), mapped to:
- LEFT column (DockNode 0x10, CentralNode=1): Theme, Project Settings,
AI Settings, Files & Media, Operations Hub
- RIGHT column (DockNode 0x01): Discussion Hub, Log Management,
Diagnostics
Verification (imgui.save_ini_settings_to_memory at runtime after
15s + first frame):
- LEFT column windows: Pos=0,28, Size=881,1697 (5 panels stacked)
- RIGHT column windows: Pos=883,28, Size=1183,1697 (3 panels stacked)
- [Docking][Data] block fully preserved (DockSpace + 8 DockNodes)
- All 8 panels docked (not floating)
