- CellRenderer::Button=5: renders SmallButton per cell; emits TableEvent::ButtonClick on click - TableEventKind enum (ButtonClick/RowDoubleClick/RowRightClick/CellEdit) + TableEvent struct - render() extended overload: adds events_out parameter (nullptr = back-compat, no events) - RowDoubleClick and RowRightClick detection in raw table loop (stage 0) - RowRightClick also detected in aggregated stage table (stage 1+) - Tooltip per cell: tooltip_on_hover + tooltip fields on ColumnSpec; "auto" = show cell value - State::aux_column_specs: TQL-persisted column specs sidecar per table - tql_emit: serializes aux_column_specs[0] as column_specs block (badge/progress/duration/icon/button/tooltip) - tql_apply: parses column_specs block back into state.aux_column_specs[0] - render() merges aux_column_specs into TableInput when caller passes empty column_specs - test_column_specs: 5->8 tests (Button struct, tooltip fields, both render() signatures link) - tql_emit_test: 3 new tests (column_specs badge/button/tooltip emit) — 52 passed - tql_apply_test: 3 new tests (column_specs badge/button/tooltip roundtrip) — 106 passed - Back-compat: existing apps (graph_explorer, registry_dashboard) unchanged - Version bump: data_table v1.1.0 -> v1.2.0 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# data_table_renderers — declarative cell renderers (v1.2.0)
|
|
|
|
Tag: `cpp-tables` (mismo grupo que TQL; los renderers son parte del stack `data_table`).
|
|
|
|
Extiende `data_table_cpp_viz` con una API declarativa para renderizar columnas con
|
|
Badge, Progress, Duration, Icon y **Button** (Phase 2), emitir eventos de interaccion
|
|
(ButtonClick, RowDoubleClick, RowRightClick), mostrar tooltips por celda y persistir
|
|
los specs en TQL (`aux_column_specs` roundtrip). Back-compat 100%: apps sin
|
|
`column_specs` ni `events_out` no necesitan cambios.
|
|
|
|
## Tipos nuevos / actualizados en `data_table_types.h`
|
|
|
|
| Tipo | Que es |
|
|
|---|---|
|
|
| `CellRenderer` | enum class: `Text=0`, `Badge=1`, `Progress=2`, `Duration=3`, `Icon=4`, **`Button=5`** |
|
|
| `BadgeRule` | value (exact match) + color_hex + label opcional |
|
|
| `IconMapEntry` | value + icon_name (ej. `"TI_BOLT"`) + color_hex opcional |
|
|
| `ColumnSpec` | id + renderer + badges / progress / duration / icon_map / **button_action, button_label, button_color_hex** / **tooltip, tooltip_on_hover** |
|
|
| `TableInput::column_specs` | `std::vector<ColumnSpec>` sidecar opcional (size 0 o == cols) |
|
|
| **`TableEventKind`** | enum class: ButtonClick=1, RowDoubleClick=2, RowRightClick=3, CellEdit=4 (reservado) |
|
|
| **`TableEvent`** | kind + row + col + column_id + action_id + value |
|
|
| **`State::aux_column_specs`** | specs persistidos en TQL (roundtrip via tql_emit/tql_apply) |
|
|
|
|
## Ejemplo canonico: Recent Executions (status Badge + duration Duration)
|
|
|
|
```cpp
|
|
#include "viz/data_table.h"
|
|
#include "core/data_table_types.h"
|
|
|
|
// --- Datos (owner externo) ---
|
|
static const char* g_exec_cells[] = {
|
|
"ok", "142",
|
|
"error", "3850",
|
|
"ok", "72",
|
|
"warn", "1100",
|
|
};
|
|
|
|
// --- Setup (una vez, en init de la app o antes del loop) ---
|
|
data_table::TableInput t;
|
|
t.name = "executions";
|
|
t.rows = 4;
|
|
t.cols = 2;
|
|
t.cells = g_exec_cells;
|
|
t.headers = {"status", "duration_ms"};
|
|
t.types = {data_table::ColumnType::String, data_table::ColumnType::Float};
|
|
|
|
// Columna 0: Badge por valor de status
|
|
data_table::ColumnSpec cs_status;
|
|
cs_status.id = "status";
|
|
cs_status.renderer = data_table::CellRenderer::Badge;
|
|
cs_status.badges = {
|
|
data_table::BadgeRule{"ok", "#22c55e", "OK"},
|
|
data_table::BadgeRule{"error", "#ef4444", "ERROR"},
|
|
data_table::BadgeRule{"warn", "#f59e0b", "WARN"},
|
|
};
|
|
|
|
// Columna 1: Duration con gradiente verde/amarillo/rojo
|
|
data_table::ColumnSpec cs_dur;
|
|
cs_dur.id = "duration_ms";
|
|
cs_dur.renderer = data_table::CellRenderer::Duration;
|
|
cs_dur.duration_warn_ms = 500.0f;
|
|
cs_dur.duration_error_ms = 2000.0f;
|
|
|
|
t.column_specs = {cs_status, cs_dur};
|
|
|
|
data_table::State st; // persiste entre frames
|
|
|
|
// --- Render loop ---
|
|
ImGui::Begin("Executions");
|
|
ImGui::BeginChild("##exec_tbl", ImVec2(-1, -1));
|
|
data_table::render("##exec", {t}, st);
|
|
ImGui::EndChild();
|
|
ImGui::End();
|
|
```
|
|
|
|
## Ejemplo: Progress bar + Icon
|
|
|
|
```cpp
|
|
data_table::ColumnSpec cs_progress;
|
|
cs_progress.id = "completion";
|
|
cs_progress.renderer = data_table::CellRenderer::Progress;
|
|
cs_progress.progress_scale_100 = true; // cell value es 0..100
|
|
cs_progress.progress_color_hex = "#3b82f6"; // azul; "" -> ImPlot auto
|
|
|
|
data_table::ColumnSpec cs_icon;
|
|
cs_icon.id = "kind";
|
|
cs_icon.renderer = data_table::CellRenderer::Icon;
|
|
cs_icon.icon_map = {
|
|
data_table::IconMapEntry{"fn", "TI_BOLT", "#3b82f6"},
|
|
data_table::IconMapEntry{"type", "TI_DATABASE", ""},
|
|
data_table::IconMapEntry{"app", "TI_SETTINGS", "#6b7280"},
|
|
};
|
|
|
|
t.column_specs = {cs_progress, cs_icon};
|
|
```
|
|
|
|
## Iconos soportados en CellRenderer::Icon
|
|
|
|
El lookup es una tabla estatica de ~30 nombres frecuentes:
|
|
|
|
```
|
|
TI_CHECK TI_X TI_ALERT_CIRCLE TI_CIRCLE_DOT
|
|
TI_CLOCK TI_LOADER TI_BAN TI_PLAYER_PLAY
|
|
TI_PLAYER_PAUSE TI_PLAYER_STOP TI_DATABASE TI_SETTINGS
|
|
TI_USER TI_USERS TI_FILE TI_FOLDER
|
|
TI_REFRESH TI_BOLT TI_INFO_CIRCLE TI_ARROW_UP
|
|
TI_ARROW_DOWN TI_ARROW_RIGHT TI_ARROW_LEFT TI_DOTS
|
|
TI_EYE TI_EYE_OFF TI_EDIT TI_TRASH
|
|
TI_COPY TI_EXTERNAL_LINK
|
|
```
|
|
|
|
Si el `icon_name` no esta en la tabla, la celda se renderiza como texto plano.
|
|
|
|
## Ejemplo Phase 2: Button + events + tooltip
|
|
|
|
```cpp
|
|
// --- Setup ---
|
|
t.column_specs.resize(t.cols);
|
|
|
|
// Columna "actions": boton Cancel por fila
|
|
t.column_specs[col_actions].renderer = data_table::CellRenderer::Button;
|
|
t.column_specs[col_actions].button_action = "cancel";
|
|
t.column_specs[col_actions].button_label = "Cancel";
|
|
t.column_specs[col_actions].button_color_hex = "#ef4444";
|
|
|
|
// Columna "status": tooltip automatico (muestra valor truncado)
|
|
t.column_specs[col_status].tooltip = "auto";
|
|
t.column_specs[col_status].tooltip_on_hover = true;
|
|
|
|
// --- Render loop ---
|
|
events.clear();
|
|
data_table::render("##t", {t}, st, &events);
|
|
|
|
// --- Procesar eventos ---
|
|
for (const auto& ev : events) {
|
|
if (ev.kind == data_table::TableEventKind::ButtonClick &&
|
|
ev.action_id == "cancel") {
|
|
cancel_row(ev.row);
|
|
}
|
|
if (ev.kind == data_table::TableEventKind::RowDoubleClick) {
|
|
open_detail(ev.row);
|
|
}
|
|
if (ev.kind == data_table::TableEventKind::RowRightClick) {
|
|
// Abrir menu propio via ImGui::BeginPopup
|
|
ctx_menu_row = ev.row;
|
|
ImGui::OpenPopup("##ctx");
|
|
}
|
|
}
|
|
```
|
|
|
|
## Ejemplo Phase 2: TQL roundtrip de column_specs
|
|
|
|
```cpp
|
|
// Persistir specs en State.aux_column_specs para guardar en .tql
|
|
data_table::ColumnSpec cs;
|
|
cs.id = "status"; cs.renderer = data_table::CellRenderer::Badge;
|
|
cs.badges = {{"ok","#22c55e","OK"},{"error","#ef4444",""}};
|
|
st.aux_column_specs = {{cs}}; // [tabla_0: {spec_col_0}]
|
|
|
|
// tql_emit serializa aux_column_specs automaticamente
|
|
std::string tql = tql::emit(st, headers, types);
|
|
// tql_apply lo recupera en res.state.aux_column_specs
|
|
auto res = tql::apply(tql, headers);
|
|
// render() lo aplica si TableInput.column_specs esta vacio
|
|
data_table::render("##t", {t}, res.state, &events);
|
|
```
|
|
|
|
## Fronteras
|
|
|
|
- **Solo Column 0..N posicional**: `column_specs[i]` aplica a la columna en posicion `i` del `TableInput` original. No se mapea por nombre.
|
|
- **Button con celda vacia**: si el cell value es vacio, NO se dibuja boton. Poner un valor no vacio en la celda para habilitar el boton.
|
|
- **No implementa TextInput/Custom** (Phase 3 separado).
|
|
- **Stage N (agregado)**: los renderers se aplican por posicion de columna del output agregado — si el breakout cambia el numero de columnas, revisar los indices.
|
|
- **RowRightClick**: en el raw table (stage 0) el evento se emite pero el popup de drill-down interno sigue abriendose. La app puede abrir su propio popup al detectar el evento.
|
|
|
|
## Gotchas
|
|
|
|
- `column_specs.size()` debe ser 0 (sin specs) o igual a `t.cols`. Mezcla de tamaños puede causar out-of-bounds silencioso (el render hace `c < column_specs.size()` guard, pero es mejor ser explicitoo).
|
|
- `hex_to_imcolor` acepta `"#rrggbb"` o `"rrggbb"`. Alpha siempre 1.0. Sin soporte para `rgba`.
|
|
- El ColorRule existente de State (`st.color_rules`) sigue funcionando — ambos sistemas coexisten. Si hay conflicto, `column_specs` toma prioridad para el contenido de la celda; `color_rules` pinta el fondo via `TableSetBgColor`.
|
|
- En el renderer Badge el `Selectable` con background coloreado consume el item para hover/click — la seleccion de rango con drag puede verse afectada visualmente en columnas Badge.
|
|
- `events_out` no se limpia en `render()` — el caller debe llamar `events.clear()` antes de cada frame.
|
|
- `aux_column_specs` solo se persiste para `tables[0]` (el main table). Specs para tablas extra deben gestionarse por el caller.
|
|
|
|
## Notas
|
|
|
|
- Tests: `cpp/tests/test_column_specs.cpp` (8 tests: 1 back-compat + 4 renderer types + 3 Phase 2). Smoke/linker; no requieren ImGui context.
|
|
- TQL roundtrip implementado en Phase 2 (issue 0081-O, v1.2.0): `tql_emit_test` (3 tests) + `tql_apply_test` (9 tests nuevos).
