Reference
This section is for details you look up while building with ModernUI.
Start with the practical guides first. Use reference pages when you need exact lifecycle rules, event routing, ownership notes, or source patterns.
Reference pages
| Page | Use it for |
|---|---|
| MuiRoot | Root setup, shutdown, timer, events, invalidation, theme, scale |
| Root and events | Required MT5 event forwarding and SetEventSink pattern |
| Event Bus | Recommended EA event routing, MuiEventData fields, and every standard app-level event |
| Controls reference | Browsable API reference entry point for controls, layout classes, data views, charts, overlays, and helpers |
| Buttons | Button controls, icon buttons, button rows, button groups, and click payloads |
| Inputs | Checkbox, toggle, slider, spin edit, text, combo, radio, date, and color inputs |
| Data views | List, table, tree, row templates, and data source APIs |

| Charts | Sparkline, line chart, bar chart, donut chart, and half gauge controls |
| Layout | Containers, windows, panels, scroll views, grids, splitters, spacers, dividers, and form rows |
| Factory helpers (reference) | MuiCreate::..., Mui::..., wrapper structs, and helper return types |
| Factory helpers | Existing Mui::... creation helper conventions |
| Fast wrapper types | Return structs such as MuiAppWindow, MuiSection, MuiButtonRow |
| Event handlers | Advanced/legacy handler ownership and safe patterns |
| Custom intent events | Optional high-level user-driven callbacks for specialist controls |
| Table and list sources | MuiItemSource, MuiTableSource, SimpleTable, ListBox |
| Ownership and lifetime | Container ownership, sources, handlers, shutdown |
