+
+# Operator layouts
+
+A **layout** is a window of the Operator Interface: optional menu and toolbars, a **frame set**
+(required) holding displays, and a status line. All layouts of a deployment are in one file,
+`%TLS_WAP_PATH%\cfg\operatorInterfaces\DEPLOY\layouts\Layouts.xml`, used by **both** the
+Operator Interface (desktop) and the HTML display (web). The complete option and command
+reference is `Layouts.readme` in the same folder; `Layouts-original.xml` is the factory copy.
+
+## 1. Rules
+
+- `Layouts.xml` is shared by every operator: back it up and change it only with the user's
+  approval. Keep project layouts in a marked block so they can be removed cleanly (sample:
+  `examples/CI-Eng-Sample/layouts/layout.ps1` + `CIENG_Operator.xml`; the script checks the XML
+  is well-formed, keeps UTF-8 without BOM and CRLF, and `-Remove` restores the file byte for byte).
+- **The Operator Interface reads `Layouts.xml` only when it starts.** After a change, close and
+  restart it. A running client does not know a new layout: opening a display in it only reloads
+  the current window ("blink"). The Edit Module also needs a restart to offer the new name in
+  the *Open display* action.
+- Name the main frame **`default`**: the factory and AOG displays (alarm lists, faceplates,
+  toolbar commands) open their targets in a frame called `default`.
+
+## 2. Structure
+
+```xml
+<layout name="<Name>" title="<text> $default" icon="poi.png" drawBorder="true"
+        sizingAllowed="true" minimizingAllowed="true" closingAllowed="true" alwaysOnTop="false"
+        initialPosition="centreScreen" initialSize="pixels" initialSizeWidth="1600"
+        initialSizeHeight="900" maximumOpen="1">
+  <menu> <menu-item name="m.file" label="File"> <menu-item … command="exit"/> </menu-item> … </menu>
+  <toolbar name="t1" floatable="false" position="top"> <toolbar-item icon="ciNavLeft32.png"
+           tooltip="Back to $" command="navigate back default"/> … </toolbar>
+  <frame-set rows="1*,fitDisplay">            <!-- main area, alarm banner below -->
+    <frame-set cols="fitDisplay,1*">          <!-- navigation left, main right -->
+      <frame name="nav" initialDisplay="<NavDisplay>" zoomingAllowed="false"/>
+      <frame name="default" initialDisplay="<Overview>" stackSize="10" zoom="fitDisplay"/>
+    </frame-set>
+    <frame name="alarmBannerFrame" initialDisplay="AOG_AlarmBanner" zoom="stretchDisplay"/>
+  </frame-set>
+  <status-line> <status-line-item type="statusText"/> <status-line-separator/> … </status-line>
+</layout>
+```
+
+- `title`: `$<frame>` = title of the display in that frame (verified: *CI-Eng-Sample - Current
+  Alarm Overview*).
+- Window: `initialPosition` (`centreScreen`, `atCursor`, `pixelsScreen2`, `centreLayout`, …),
+  `initialSize` (`pixels`, `screenSize`, `desktopSize`, `fitFrames`), `maximumOpen`, `modal`,
+  `alwaysOnTop`, print options.
+- Frame sets: `rows` / `cols` with pixels, `n*` fractions or `fitDisplay`; nest freely; a `<tab>`
+  holds several frames as tabs (`tabPosition`, `maximumTabs`, `closeTabAllowed`). Frame options:
+  `name`, `initialDisplay` (= home display), `stackSize` (back/forward history), `zoom`
+  (`fitDisplay`, `stretchDisplay`, `<n>%`), `zoomingAllowed`, `scrollingAllowed`, `borderStyle`.
+- Menu (max. two levels; `type` normal/check/radio/sub; `mnemonic`, `accelerator` like `F5`,
+  `CONTROL P`) and toolbar items (`icon` from the factory set such as `ciNavLeft32.png`,
+  `ciProAlar32.png`, `ciZoomFull32.png`; `type` combo/editableCombo/dropdownList) run commands:
+
+| Command | Effect |
+|---|---|
+| `navigate to <frame> <display> [<zoom>] [<p>=<v>;…]` | Open a display in a frame (with parameters) |
+| `navigate back/forward/up/home/history <frame>` | Frame history (`$` in the tooltip = target name) |
+| `reload <frame>` / `reload all` | Reload displays (keeps the session in the HTML display) |
+| `zoom <level> <frame>` | 0 = fit, 1 = 100 %, 10–1000 = relative % |
+| `toggleSize fullScreen [n]` / `toggleSize x,y,WxH` | Full screen / given size and back |
+| `print frame|frameWithSetup|preview|setup|selectFrame` | Printing (desktop only) |
+| `login`, `logout`, `exit`, `toolbar`, `statusline`, `playback record|view`, `shell client|server <cmd>`, `lookfeel <class>`, `help` | |
+
+  The installed status line also uses item types `displayName`, `playbackIndicator` and
+  `dateTime`, which the readme does not list (ISS-042).
+- `<translations name="nl">` blocks translate labels per locale (key = item name + `.label`).
+
+## 3. Opening displays in frames and layouts
+
+| From | How |
+|---|---|
+| Button / component (Edit Module, *Actions* sheet → *Open display*) | Display, **Layout** (empty = current window), **Frame**, parameters; stored as `<action type="actionActivateDisplay">` with `<type … value="ActivateSpecific"/>`, `<display>`, `<layout>`, `<layoutFrame>` |
+| Menu / toolbar | `navigate to <frame> <display>` (current window only) |
+| Login | User profile *Layout* and *Initial display* (Engineering Module, Authorization > Users); empty layout = `default` (from docs; not changed on the test system) |
+| HTML display | URL `?d=<display>&l=<layout>` |
+| Script on a component | *Execute command* with `ACTION <layout command>`, e.g. `ACTION toggleSize 50,50,710x520` |
+
+Verified behaviour (desktop): a button with layout `CIENG_Operator` opened a **second window**
+(1600 × 900, own menu/toolbar/frames); buttons without layout opened their display in the main
+frame of the current window; **Back** returned. A button with layout `popup` opened a separate
+window: always on top, only a close button, sized to the display (`fitFrames`), and minimised
+together with the window that opened it — use popups only for small displays (faceplates,
+setpoint dialogs).
+
+## 4. Typical project layouts
+
+- **Operator main window**: navigation frame + main frame `default` (+ tabs) + alarm banner,
+  project menu/toolbar, assigned to operators via the user profile *Layout*.
+- **Kiosk / control-room screen**: `drawBorder="false"`, `alwaysOnTop="true"`,
+  `initialSize="screenSize"`, `closingAllowed="false"`, `minimizingAllowed="false"`.
+  `toggleSize fullScreen` covers the taskbar only when `alwaysOnTop="true"` (verified: with
+  `false` the title bar and taskbar stay).
+- **Popups / faceplates**: small layout with one frame `default`, `initialSize="fitFrames"`,
+  `initialPosition="atCursor"`, `alwaysOnTop="true"`, `maximumOpen` > 1 for several faceplates
+  (factory: `popup`, `FixedPopup`, `ResizablePopup`, `faceplate`, `tuningpanel`, `Setpoint`,
+  `SelectMode`).
+- **Several screens**: one layout per screen with `initialPosition="pixelsScreen2"` /
+  `centreScreen2`, or the dual-screen pattern of IM 36K10R30 §1.10.
+
+## 5. HTML display differences
+
+The browser window is the main layout (its size and window options are ignored); other layouts
+open as windows inside the page; print, look-and-feel and the debug key are not supported; pick
+the layout with `&l=`. Verified: `?d=CIENG_Tank&l=CIENG_Operator` showed the sample menu,
+toolbar, navigation frame and banner.
+
+## Verified (CI-Eng-Sample, 2026-10-01)
+
+`layout.ps1` add / remove / add (removal identical to the original, backup kept); Operator
+Interface restart required before the layout was found; desktop and web windows as described
+above; F11 (`toggleSize fullScreen`) worked within the taskbar limits; after restarting the
+Operator Interface the main window still used the factory `default` layout (Admin profile
+unchanged).
