## Description

GUI Manager for panels, consoles and debug windows [v26.05.0].

### Overview

The GUI module provides the engine-managed runtime GUI layer through the GUI Manager. It handles three object families: Panels (widget containers), Consoles (interactive command-line overlays) and Debug Windows (runtime variable monitors). Panels can optionally arrange their child widgets using horizontal or vertical flow layout while preserving their behavioral type (modeless, modal or ephemeral). GUI objects are attached to screens, support multi-screen configurations, and can be saved and loaded through the CDC GUI format. Widget lifecycle is split into visibility (show() / hide()) and interactivity (enable() / disable()), so controls can remain visible while disabled.
See Widget module for skin properties, feature flags, callbacks, state machine and update protocol.

### Key features

- Panel system: Widget containers with modeless, modal and ephemeral (TTL) behavior
- Panel flow layouts: Optional horizontal and vertical flow layout with configurable spacing, padding, justify and alignment
- Console: In-game command-line interface with history, built-in commands and TAB auto-complete
- Debug window: Runtime watch windows for Sint32 and float variables with configurable refresh interval
- Widget set: Label, Image, Frame, Button, CheckBox, Progress, Slider, TextEdit, NumberEdit, List, ComboBox
- Theming: Built-in Default, Dark and Flat themes; custom themes created at runtime via createTheme()
- Tooltips: Delayed hover tooltips with fade-in, per-widget TTL, cursor-follow and themed visuals
- Multi-screen routing: GUI objects attach to specific screens; events are filtered by windowID
- Separated widget lifecycle: Visibility and enabled state are managed independently
- Inspection and persistence: Enumerate widgets, inspect metadata, save and load GUI state through CDC

### GUI object types

Panel | Container for widgets. Supports modeless, modal and time-to-live (TTL) ephemeral behavior. Panels are ref-counted: loading a panel whose name already exists returns the existing panel and increments its reference count. Optional flow layout for automatic child arrangement.
Console | Command-line interface with prompt, UTF-8 cursor navigation, command history, TAB auto-complete and custom command registration. Captures SDL text input focus while allowing other GUI interactions. Read-only mode available.
DebugWindow | Variable watch window for monitoring Sint32* and float* pointers in real-time. Configurable refresh interval. add/removeWatch fail gracefully when the window is disabled.

### Render order

Render pass order, from bottom to top:

1. Panels | Rendered back-to-front by focus vector (vPanelID). Open ComboBox popups are rendered in a second panel pass above normal panel widgets.
2. Tooltip | Manager-owned overlay drawn above panels but below DebugWindows and Consoles. Uses the active theme shared tooltip style, optionally overridden per widget.
3. DebugWindows | Rendered on top of panels and tooltips. Drag-drop capable.
4. Consoles | Always on top of panels, tooltips and debug windows.

### Update priority

Input/update priority is processed from topmost interactive overlays down to panels:

1. DebugWindows | Checked first so overlay activity can block drag/drop and lower GUI layers.
2. Consoles | Checked before panels so text input focus and overlay activity can prevent panel interaction underneath.
3. Panels | Front panel receives events first. Modal panels can block lower panels.
4. Tooltip State | Resolved after object updates so tooltip ownership uses the final hover/focus state for the frame.

### Panel flow layout

Panels can automatically arrange their child widgets using a one-dimensional flow layout. The layout is selected via setLayout() and configured with setLayoutSpacing(), setLayoutPadding(), setLayoutJustify() and setLayoutAlign(). The layout re-runs (reflow()) whenever the internal dirty flag is raised: on widget creation, widget removal, widget resize, widget show/hide, panel show, and explicit invalidateLayout() calls. Widget positions under a flow layout are set by calling Widget::setPosition() with absolute pixel coordinates computed by the reflow pass.

PL_NONE | No layout. Widgets are positioned manually. Default.
PL_HFLOW | Horizontal flow. Widgets are placed left-to-right. Main axis is X, cross axis is Y.
PL_VFLOW | Vertical flow. Widgets are placed top-to-bottom. Main axis is Y, cross axis is X.

Layout justify options (eLayoutJustify) - main axis distribution

LJ_START | Widgets packed to the start of the main axis (after padding). Default.
LJ_CENTER | Widgets centered along the main axis. If total widget size exceeds the inner dimension the cursor may go negative; widgets are silently clamped by WF_ENCLOSE.
LJ_END | Widgets packed to the end of the main axis. Same overflow clamp caveat as LJ_CENTER.
LJ_SPACE | Spacing is distributed evenly between widgets. With a single visible widget, spacing is the configured iLayoutSpacing value.

Layout align options (eLayoutAlign) - cross axis positioning

LA_START | Widgets aligned to the start of the cross axis (after cross padding).
LA_CENTER | Widgets centered along the cross axis. Default.
LA_END | Widgets aligned to the end of the cross axis.
LA_STRETCH | Widget cross-axis size is expanded to fill the available inner cross dimension. setSize() is called on each widget during reflow.

Note
  Showing or hiding a widget automatically invalidates the parent panel layout. Use Panel::invalidateLayout() only for caller-controlled edge cases where no widget creation, removal, resize or visibility change occurs.

### Console features

Command registration | addCmdHandler() registers user commands with a name, help text and callback. The command name must be unique and cannot be "help".
Built-in commands | 'help', 'con', 'dw' and 'cur' are always available. Parameters for auto-complete are registered internally via setCmdParams().
Command history | Up/Down arrow keys recall and cycle previously executed commands.
TAB auto-complete | Single match: completes immediately. Multiple matches: prints list and expands to the common prefix. Repeated TAB cycles through matches.
Input focus | Captures SDL_EVENT_TEXT_INPUT, blocking it from reaching panels below. Read-only mode disables text input and command execution while keeping the console visible.
Clipboard | Ctrl+C copies the current prompt line. Ctrl+V pastes at the current cursor position.

### DebugWindow features

Variable watch | addWatch() accepts a display name, an optional Sint32* and an optional float*. At least one pointer must be non-null. Watch names must be unique.
Refresh interval | setRefreshInterval() configures the update period in milliseconds. Default is 500 ms. The timer is driven by an explicit init flag (bRefreshTimerInit) rather than a zero-sentinel to avoid edge cases at startup.
Named watches | Each watch has a display name shown before its values. Format: "name integer float" or "name integer" or "name float" depending on which pointers are set.
Disabled guard | addWatch() and removeWatch() return -1 immediately when the DebugWindow base widget is in GS_DISABLED state.

### Manager types

Panel | Shared-name management: loading a CDC block whose panel name already exists returns the existing panel and increments its reference count. close() decrements the count and destroys the panel only when it reaches zero.
Console | Standard manager: names must be unique. The first console created (GUICONSOLE_SIGNATURE) is the default console and cannot be closed or disabled.
DebugWindow | Standard manager: names must be unique.

### Tooltip behavior

Tooltips are driven by widget text assigned through Widget::setTooltip(). The GUI manager shows them after GUI_TOOLTIP_DELAY_MS (1000 ms) of stable hover, with a fade-in over GUI_TOOLTIP_FADEIN_MS (500 ms). Tooltip visuals use the active theme's shared tooltip style, unless the hovered widget overrides tooltip background, border or font locally. The tooltip is positioned near the cursor with GUI_TOOLTIP_OFFSET_X / GUI_TOOLTIP_OFFSET_Y and clamped to the screen bounds. Per-widget TTL is read from Widget::getTooltipTTL(); the widget default is WIDGET_TOOLTIP_DEFAULT_TTL_MS = 0, meaning the tooltip stays visible while the hover is valid. GUI_TOOLTIP_TTL_MS is only the manager's bootstrap/fallback value used before a concrete widget owner is latched. After a tooltip expires, it will not show again for the same widget until the pointer leaves and re-hovers. Tooltip display is dismissed early by keyboard input, text input events, mouse button press or mouse wheel while a tooltip is visible. Mouse button release is intentionally ignored because the press already represents the user intent to dismiss.

### Themes

GUI themes define procedural widget styling per widget type and widget state. Built-in themes are available immediately through GUIMgr::getThemeDefault(), GUIMgr::getThemeDark() and GUIMgr::getThemeFlat(). Theme resolution order for any skin property: widget override, then panel theme override, then global theme, then built-in Default theme. A typical workflow is:

GUIMgr& gui = Main::instance().guiMgr();
gui.setGlobalTheme(gui.getThemeDark());
CRM64Pro::GUIMgr::setGlobalTheme
Sint32 setGlobalTheme(Sint32 idTheme)
Set the active global theme.
Definition GUI.cpp:1685
CRM64Pro::Main::guiMgr
GUIMgr & guiMgr()
Get reference to GUI Manager.
Definition CoreMain.cpp:1010
CRM64Pro::Main::instance
static Main & instance()
Access the Main singleton.
Definition CoreMain.cpp:453

To customize a theme:

Sint32 idTheme = gui.createTheme("MyTheme");
GUITheme* pTheme = gui.getTheme(idTheme);
if(pTheme)
{
pTheme->setSkinBackgroundColor(WT_BUTTON, WS_NORMAL, 32, 96, 160);
pTheme->setSkinFontName(WT_BUTTON, WS_NORMAL, "@c64/font/Arial12White");
}
CRM64Pro::WT_BUTTON
@ WT_BUTTON
Standard button widget.
Definition CRM64Pro.h:5955
CRM64Pro::WS_NORMAL
@ WS_NORMAL
Normal widget state.
Definition CRM64Pro.h:5941

Custom themes created via createTheme() are pre-filled from the Default theme. Theme entries are inspected through GUITheme::getSkin() and modified through the explicit GUITheme::setSkin...() methods. Built-in fonts should use the full "@c64/font/..." name in GUIThemeSkin::sFontName to avoid name collisions with user-loaded fonts. Theme font resolution first checks FontMgr::getBuiltin(), then FontMgr::get() by name.

### Best practices

- Use GUI objects from the main thread only; there is no internal synchronization
- Set a global theme through GUIMgr::setGlobalTheme(), then override individual panels or widgets only when needed. This minimizes per-widget skin data in CDC files
- Widget show()/hide(), creation, removal and resize automatically invalidate parent flow layouts; use Panel::invalidateLayout() only for caller-controlled edge cases
- Use widget tooltips for hover help text and panel TTL (ephemeral panels) for temporary HUD notifications
- Register custom console commands during initialization for in-game debugging; use addCmdHandler() with setCmdParams() to enable TAB auto-complete for your command parameters
- Use DebugWindow during development to monitor critical game variables; remove or hide it in release builds
- Attach GUI objects to the correct screen in multi-screen configurations; events are filtered by windowID and objects on a hidden screen receive the crafted focus-lost event
- Access the manager exclusively through Main::guiMgr()

Note
  The GUI Manager is a singleton, automatically created once Main is instantiated. You can get a reference to it using Main::guiMgr().
  The GUI Manager is automatically released when Main::terminate() is called. Any resource still loaded at that point is released, avoiding leaks.
