## MainWindow
```
```markdown
class omni.kit.mainwindow.MainWindow
```
```markdown
Bases: object
A class that represents the main application window in OmniKit.
This class manages the initialization, display, and cleanup of the main window. It provides methods to toggle the visibility of the main menu and status bar, as well as to asynchronously dock various application windows at startup. The main window is set up with custom settings that are retrieved from the application’s settings.
### Methods
- **__init__()**
- Initializes the main window with customized settings and potentially starts window docking.
- **destroy()**
- Cleans up the main window by setting its reference and setup window task to None.
- **get_main_menu_bar()**
- Returns the main menu bar.
- **get_status_bar_frame()**
- Returns the frame containing the status bar.
- **show_hide_menu()**

| Function Name | Description |
|---------------|-------------|
| `show_hide_status_bar()` | Toggles the visibility of the status bar. |
### __init__()
Initializes the main window with customized settings and potentially starts window docking.
The main window is initialized with a gray foreground to hide undocked windows during the first several frames.
The visibility of the main menu bar is set based on the application’s release status. Settings for margins,
background color, and whether to dock windows on startup are retrieved and applied to the main window.
If docking is enabled, an asynchronous task is created to dock the windows.
### destroy()
Cleans up the main window by setting its reference and setup window task to None.
### get_main_menu_bar() → MenuBar
Returns the main menu bar.
- **Returns:** The main menu bar.
- **Return type:** ui.MenuBar

omni.kit.mainwindow.MainWindowExtension.md | # MainWindowExtension
## MainWindowExtension
An omni.ext.IExt extension to manage the main window of an application.
This extension provides lifecycle management for the `MainWindow` instance, creating it upon startup and destroying it on shutdown. It ensures that there is a global access point to the main window through the `get_main_window` function.
### Methods
- `on_shutdown()`: Cleans up resources related to the main window when the extension shuts down.
- `on_startup(ext_id)`: Initializes the main window when the extension starts up.
### `__init__(self: omni.ext._extensions.IExt) -> None`
### `on_shutdown()`
Cleans up resources related to the main window when the extension shuts down.
This method destroys the MainWindow instance if it exists and sets the
global variable to None, ensuring that all resources are properly
released.
### on_startup
Initializes the main window when the extension starts up.
This method creates a new instance of the MainWindow class and assigns it
to a global variable so that it can be accessed from anywhere within
the application.
#### Parameters
**ext_id** (`str`) – The ID of the current extension. | 1,163 |

## ManipulatorBase
```python
class omni.kit.manipulator.selector.ManipulatorBase(name: str, usd_context_name: str)
```
Base class for prim manipulator that works with ManipulatorSelector. Instead of subscribing to UsdStageEvent for selection change, manipulator should inherit this class and implements all abstractmethods to support choosing between multiple types of prim manipulators based on their order and enable criterions.
The order of the manipulator is specified at carb.settings path `/persistent/exts/omni.kit.manipulator.selector/orders/<name>”`
### Methods
| Method | Description |

| enabled | Returns if this manipulator is enabled. |
### __init__
**Constructor.**
**Parameters:**
- **name** (str) – name of the manipulator. It must match the `<name>` in the setting path specifies order.
- **usd_context_name** (str) – name of the UsdContext this manipulator operates on.
### on_selection_changed
**Function called when selection changes or types of prim manipulators are added or removed.**
**Parameters:**
- **stage** (Usd.Stage) – the usd stage of which the selection change happens. It is the same as the stage of the UsdContext this manipulator works on.
- **selection** (Union[List[Sdf.Path], None]) – the list of selected prim paths. If it is None (different from []), it means another manipulator with higher priority has handled the selection and this manipulator should yield.
**Returns:**
True if selected prim paths can be handled by this manipulator and subsequent manipulator with higher order should yield. False if selected prim paths can not be handled. Function should always return False if `selection` is None.

Parameters
### AbstractTransformManipulatorModel Methods
#### set_ints
```python
set_ints(item: AbstractManipulatorItem, value: List[int])
```
Called when the manipulator is being dragged and value changes, or set by external code to overwrite the value. The model should update value to underlying data holder(s) (e.g. a USD prim(s)). Depending on the model implementation, item and value can be customized to model’s needs.
**Parameters:**
- **item** (`sc.AbstractManipulatorItem`) – input manipulator item.
- **value** (`List[int]`) – a composed Matrix4x4 transform in world space as a list of int.
#### widget_disabled
```python
widget_disabled()
```
Called by hosting manipulator widget(s) when they’re disabled. It can be used to track if any hosting manipulator is active to skip background model update (i.e. running listener for changes).
#### widget_enabled
```python
widget_enabled()
```
Called by hosting manipulator widget(s) when they’re enabled. It can be used to track if any hosting manipulator is active to skip background model update (i.e. running listener for changes). | 7,266 |

omni.kit.manipulator.transform.ScaleChangedGesture.md | # ScaleChangedGesture
## ScaleChangedGesture
```python
class omni.kit.manipulator.transform.ScaleChangedGesture(**kwargs)
```
Bases: `TransformChangedGesture`
A gesture representing a change in scaling during an interaction with a manipulator.
This gesture is used internally to handle manipulator interactions in a omni.ui.scene.SceneView for scaling operations. It is part of the gesture system that responds to the beginning, modification, ending, or canceling of a scaling action and is responsible for updating the state of the transformation and optionally blocking other omni.ui.scene.SceneView interactions while active.
### Methods
### Attributes
```python
def __init__(**kwargs)
```
Initializes the TransformChangedGesture.
``` | 746 |
omni.kit.manipulator.transform.TransformChangedGesture.md | # TransformChangedGesture
## Overview
A gesture representing a change in a transformation, such as translation, rotation, or scaling.
This gesture is part of the mechanism for handling transformation manipulations in a omni.ui.scene.SceneView. It is triggered when a transformation action begins, changes, ends, or is canceled. It is responsible for updating the transformation state and potentially preventing other omni.ui.scene.SceneView interactions while a transformation is active.
### Parameters
- **kwargs** – Variable length keyword arguments.
## Methods
- **__init__(**kwargs)**
- Initializes the TransformChangedGesture.
- **on_began()**
- Handler for the beginning state of the gesture.
- **on_canceled()**
- Handler for the canceled state of the gesture.
- **on_changed()**
- Handler for the changed state of the gesture.
<p>Handler for the changed state of the gesture.
<p>Handler for the ended state of the gesture.
<p>Processes the gesture and determines the appropriate action based on its state.
<p class="rubric">Attributes
