omni.kit.widget.graph.GraphModel.md | # GraphModel
## GraphModel
The base class for the Graph model.
The model is the central component of the graph widget. It is the application’s dynamic data structure, independent of the user interface, and it directly manages the data. It follows closely model–view pattern. It defines the standard interface to be able to interoperate with the components of the model-view architecture. It is not supposed to be instantiated directly. Instead, the user should subclass it to create a new model.
The model manages two kinds of data elements. Node and port are the atomic data elements of the model. Both node and port can have any number of sub-ports and any number of input and output connections.
There is no specific Python type for the elements of the model. Since Python has dynamic types, the model can return any object as a node or a port. When the widget needs to get a property of the node, it provides the given node back to the model.
Example:
```python
class UsdShadeModel(GraphModel):
@property
def nodes(self, prim=None):
# Return Usd.Prim in a list
return [stage.GetPrimAtPath(selection)]
@property
def name(self, item=None):
# item here is Usd.Prim because UsdShadeModel.nodes returns
# Usd.Prim
return item.GetPath().name
# Accessing nodes and properties example
model = UsdShadeModel()
# UsdShadeModel decides the type of nodes. It's a list with Usd.Prim
nodes = model.nodes
for node in nodes:
# The node is accessed through evaluation of self[key]. It will
# return the proxy object that redirects its properties back to
# model. So the following line will call UsdShadeModel.name(node).
name = model[node].name
print(f"The model has node {name}")
```

omni.kit.widget.graph.GraphNodeDelegateRouter.md | # GraphNodeDelegateRouter
## GraphNodeDelegateRouter
```python
class omni.kit.widget.graph.GraphNodeDelegateRouter
```
**Bases:**
```python
AbstractGraphNodeDelegate
```
**Description:**
The delegate that keeps multiple delegates and pick them depending on the routing conditions.
It’s possible to add the routing conditions with `add_route`, and conditions could be a type or a lambda expression.
The latest added routing is stronger than previously added. Routing added without conditions is the default.
We use type routing to make the specific kind of nodes unique, and also we can use the lambda function to make the particular state of nodes unique (ex. full/collapsed).
It’s possible to use type and lambda routing at the same time.
**Usage examples:**
```python
delegate.add_route(TextureDelegate(), type="Texture2d")
delegate.add_route(CollapsedDelegate(), expression=is_collapsed)
```
### Methods
| Method | Description |
|--------|-------------|
| `__init__()` | |
| `add_route(delegate[, type, expression])` | Add delegate to the routing table |
| `connection(model, source, target[, foreground])` | Called to create the connection between ports |
| `destroy()` | |
| `get_node_layout()` | |
```

### Attributes
| Attribute | Description |
| --- | --- |
| DEFAULT_DISTANCE_BETWEEN_NODES | |
| model | |
| pan_x | The horizontal offset of the scene |
| pan_y | The vertical offset of the scene |
| raster_nodes | |
| selection | Return selected nodes |
| virtual_ports | Typically source connections go from the left side of the node to the right side of the node. |
| zoom | The zoom level of the scene |
| zoom_max | The maximum zoom level of the scene |
| zoom_min | The minimum zoom level of the scene |
## zoom_min

### Keyword Arguments:
- `model GraphModel`
- Model to display the node graph
- `delegate AbstractGraphNodeDelegate`
- Delegate to draw the node
- `virtual_ports bool`
- True when the model should use reversed output for better look of the graph.
- `port_grouping bool`
- True when the widget should use sub-ports for port grouping.
- `draw_curve_top_layer bool`
- When True, connections are drawn in 2 passes. The “under” layer is for the opaque curve, and the “top” or “over” layer is meant for floating curve anchor decorations that need to be on top of all nodes, like a value display. Its curve should be drawn transparent. False by default, so both layers are not drawn.
- `allow_same_side_connections bool`
- When True, connections can happen between two input ports or two output ports. This is only used within one node. We don’t support same side connection between different nodes yet.
All other kwargs are passed to CanvasFrame which is the root widget.
## destroy
Called by extension before destroying this object. It doesn’t happen automatically. Without this hot reloading doesn’t work.

## Classes Summary
- **SugiyamaLayout**
- Compute the coordinates for drawing directed graphs following the method | 155 |
omni.kit.widget.graph.graph_layout.SugiyamaLayout.md | # SugiyamaLayout
## Overview
The `SugiyamaLayout` class is designed to compute the coordinates for drawing directed graphs following the method developed by Sugiyama. This method involves four main phases:
1. Cycle Removal
2. Layer Assignment
3. Crossing Reduction
4. Coordinate Assignment
The input for this class is a list of edges in the format: `[(vertex1, vertex2), (vertex3, vertex4), ...]`. Once the `SugiyamaLayout` object is created, it's possible to get the node layer number immediately. To get the node positions, it's necessary to set each node's size and call `update_positions`.
The implementation follows closely to the following papers:
- [1] "An Efficient Implementation of Sugiyama’s Algorithm for Layered Graph Drawing" by Eiglsperger, Siebenhaller, and Kaufmann
- [2] "Sugiyama Algorithm" by Nikolov
- [3] "Graph Drawing Algorithms in Information Visualization" by Frishman
## Methods
- `__init__(edges=[], vertical_distance=10.0, horizontal_distance=10.0)`
- `get_layer(vertex)`
The layer id of the node
get_position (vertex)
The position of the node
set_size (vertex, width, height)
Set the size of the node
update_positions ()
1. Coordinate Assignment
__init__ (edges = [], vertical_distance = 10.0, horizontal_distance = 10.0)
class Node (id)
Bases: object
Temporary node that caches all the intermediate compute data
add_upstream (node)
Add the upstream node. It will add current node to downstream as well.
get_layer (vertex)
The layer id of the node
get_position (vertex)
The position of the node
set_size (vertex, width, height)
Set the size of the node
## Node Size Setting
Set the size of the node
## Update Positions

| [GraphModel](omni.kit.widget.graph.graph_model/omni.kit.widget.graph.graph_model.GraphModel.html) | The base class for the Graph model. | | 253 |
omni.kit.widget.graph.graph_model.GraphModel.md | # GraphModel
## GraphModel
```
class omni.kit.widget.graph.graph_model.GraphModel
```
The base class for the Graph model.
The model is the central component of the graph widget. It is the application’s dynamic data structure, independent of the user interface, and it directly manages the data. It follows closely model–view pattern. It defines the standard interface to be able to interoperate with the components of the model-view architecture. It is not supposed to be instantiated directly. Instead, the user should subclass it to create a new model.
The model manages two kinds of data elements. Node and port are the atomic data elements of the model. Both node and port can have any number of sub-ports and any number of input and output connections.
There is no specific Python type for the elements of the model. Since Python has dynamic types, the model can return any object as a node or a port. When the widget needs to get a property of the node, it provides the given node back to the model.
Example:
```python
class UsdShadeModel(GraphModel):
@property
def nodes(self, prim=None):
# Return Usd.Prim in a list
return [stage.GetPrimAtPath(selection)]
@property
def name(self, item=None):
# item here is Usd.Prim because UsdShadeModel.nodes returns
# Usd.Prim
return item.GetPath().name
# Accessing nodes and properties example
model = UsdShadeModel()
# UsdShadeModel decides the type of nodes. It's a list with Usd.Prim
nodes = model.nodes
for node in nodes:
# The node is accessed through evaluation of self[key]. It will
# return the proxy object that redirects its properties back to
# model. So the following line will call UsdShadeModel.name(node).
name = model[node].name
print(f"The model has node {name}")
| Method | Description |

| `can_connect(source, target)` | Return if it's possible to connect source to target |
| `destroy()` | |
| `has_nodes(obj)` | Returns true if the model can currently build the graph network using the provided object |
| `position_begin_edit(item)` | Called when the user started dragging the node |

| `size_begin_edit(item)` | Called when the user started resizing the node |
| `size_end_edit(item)` | Called when the user finished resizing the node and released the mouse |
| `special_select_widget(node, node_widget)` | |

## GraphNodeDelegateRouter
Bases: `AbstractGraphNodeDelegate`
The delegate that keeps multiple delegates and pick them depending on the routing conditions.
It’s possible to add the routing conditions with `add_route`, and conditions could be a type or a lambda expression.
The latest added routing is stronger than previously added. Routing added without conditions is the default.
We use type routing to make the specific kind of nodes unique, and also we can use the lambda function to make the particular state of nodes unique (ex. full/collapsed).
It’s possible to use type and lambda routing at the same time.
Usage examples:
```
delegate.add_route(TextureDelegate(), type="Texture2d")
delegate.add_route(CollapsedDelegate(), expression=is_collapsed)
```
### Methods
- `__init__()`
- `add_route(delegate[, type, expression])`
- Add delegate to the routing table

omni.kit.widget.graph.graph_view.GraphView.md | # GraphView
## GraphView
```python
class omni.kit.widget.graph.graph_view.GraphView(**kwargs)
```
### Keyword Arguments:
```python
def __init__(**kwargs)
```
```python
def destroy()
```
Called by extension before destroying this object.
```python
def filter_upstream(nodes)
```
Remove nodes that are not upstream of the given nodes
```python
def focus_on_nodes([nodes])
```
Focus the view on nodes
```python
def get_bbox_of_nodes([nodes])
```
| Method | Description |
| --- | --- |
| `layout_all()` | Reset positions of all the nodes in the model |
| `set_delegate(delegate)` | Replace the delegate of the widget |
| `set_expansion(state)` | Open, close or minimize all the nodes in the model |
| `set_model(model)` | Replace the model of the widget |
| `subscribe_empty_connection_drop(fn)` | Return the object that will automatically unsubscribe when destroyed |
| `subscribe_post_delayed_build_layout(fn)` | Return the object that will automatically unsubscribe when destroyed |
| `subscribe_pre_delayed_build_layout(fn)` | Return the object that will automatically unsubscribe when destroyed |
### Attributes
| Attribute | Description |
| --- | --- |
| `DEFAULT_DISTANCE_BETWEEN_NODES` | |
| `model` | |
| `pan_x` | The horizontal offset of the scene |
| `pan_y` | The vertical offset of the scene |
| `raster_nodes` | |
| `selection` | Return selected nodes |
| `virtual_ports` | Typically source connections go from the left side of the node to the right side of the node |
| `zoom` | The zoom level of the scene |
| zoom_max | The maximum zoom level of the scene |
|----------|-------------------------------------|
| zoom_min | The minimum zoom level of the scene |
### Keyword Arguments:
- `model <span class="classifier">GraphModel`
- Model to display the node graph
- `delegate <span class="classifier">AbstractGraphNodeDelegate`
- Delegate to draw the node
- `virtual_ports <span class="classifier">bool`
- True when the model should use reversed output for better look of the graph.
- `port_grouping <span class="classifier">bool`
- True when the widget should use sub-ports for port grouping.
- `draw_curve_top_layer <span class="classifier">bool`
- When True, connections are drawn in 2 passes. The “under” layer is for the opaque curve, and the “top” or “over” layer is meant for floating curve anchor decorations that need to be on top of all nodes, like a value display. Its curve should be drawn transparent. False by default, so both layers are not drawn.
- `allow_same_side_connections <span class="classifier">bool`
- When True, connections can happen between two input ports or two output ports. This is only used within one node. We don’t support same side connection between different nodes yet.
All other kwargs are passed to CanvasFrame which is the root widget.
### __init__
- **kwargs
- kwargs
### destroy
- Called by extension before destroying this object. It doesn’t happen automatically. Without this hot reloading doesn’t work.
### filter_upstream
- nodes : list
- Remove nodes that are not upstream of the given nodes
### focus_on_nodes
- nodes : Optional[List[Any]] = None
- Focus the view on nodes
### get_bbox_of_nodes
- nodes
- (Unfinished content)
### GraphView Methods
#### get_bbox_of_nodes()
Get the bounding box of nodes
#### layout_all()
Reset positions of all the nodes in the model
#### set_delegate(delegate: AbstractGraphNodeDelegate)
Replace the delegate of the widget
#### set_expansion(state: ExpansionState)
Open, close or minimize all the nodes in the model.
#### set_model(model: GraphModel)
Replace the model of the widget. It will refresh all the content.
#### subscribe_empty_connection_drop(fn)
Return the object that will automatically unsubscribe when destroyed.
#### subscribe_post_delayed_build_layout(fn)
Return the object that will automatically unsubscribe when destroyed.
#### subscribe_pre_delayed_build_layout(fn)
Return the object that will automatically unsubscribe when destroyed.

<p>
Typically source connections go from the left side of the node to the
right side of the node. But sometimes it looks messy when circular
connections. When `virtual_ports` is true, and the connection is
circular, the view draws it from the right side to the left side.

omni.kit.widget.graph.IsolationGraphModel.md | # IsolationGraphModel
## IsolationGraphModel
```python
class omni.kit.widget.graph.IsolationGraphModel(model: GraphModel, root)
```
### Methods
- `__init__(model, root)`
- `add_input_or_output(position[, is_input])`
- `can_connect(source, target)` - Return if it's possible to connect source to target
- `clear_caches()`
- `destroy()`
- `position_begin_edit(item)`
```
| Code Block | Description |
|------------|-------------|
| `position_end_edit` (item) | |
| `subscribe_item_changed` (fn) | Return the object that will automatically unsubscribe when destroyed. |
| `subscribe_node_changed` (fn) | Return the object that will automatically unsubscribe when destroyed. |
| `subscribe_selection_changed` (fn) | Return the object that will automatically unsubscribe when destroyed. |
| `nodes` | It's only called to get the nodes from the top level |
| `selection` | |
### Attributes
#### `__init__`
```python
__init__(model: GraphModel, root)
```
#### `EmptyPort`
```python
class EmptyPort(parent: Union[InputNode, OutputNode])
```
Bases: `object`
Is used by the model for an empty port
##### `get_type_name`
```python
static get_type_name() -> str
```
The string type that goes the source model and view
### InputNode
```python
class InputNode(model: GraphModel, source)
```
Bases: `object`
Is used by the model for the input node. This node represents input ports of the compound node and it’s placed to the subnetwork of the compound.
#### get_type_name
```python
static get_type_name() -> str
```
The string type that goes the source model and view
#### ports
```python
property ports : Optional[List[Any]]
```
The list of ports of this node. It only has input ports from the compound node.
### MagicWrapperMeta
```python
class MagicWrapperMeta(name, bases, dct)
```
Bases: `type`
Python always looks in the class (and parent classes) __dict__ for magic methods and __getattr__ doesn’t work, but since we want to override them, we need to use this trick with proxy property.
It makes the class looking like the source object.
See [https://stackoverflow.com/questions/9057669](https://stackoverflow.com/questions/9057669) for details.
### OutputNode
```python
class OutputNode(model: GraphModel, source)
```
Bases: `object`
Is used by the model for the output node. This node represents output ports of the compound node and it’s placed to the subnetwork of the compound.

```
### Class
```python
class EmptyPort(parent: Union[InputNode, OutputNode])
```
- **Bases:** `object`
- **Description:** Is used by the model for an empty port
### Method in Class EmptyPort
```python
static get_type_name()
```
### IsolationGraphModel.EmptyPort.get_type_name
The string type that goes the source model abd view
### IsolationGraphModel.InputNode
Bases: `object`
Is used by the model for the input node. This node represents input ports of the compound node and it’s placed to the subnetwork of the compound.
#### InputNode.get_type_name
The string type that goes the source model and view
#### InputNode.ports
The list of ports of this node. It only has input ports from the compound node.
### IsolationGraphModel.MagicWrapperMeta
Bases: `type`
Python always looks in the class (and parent classes) __dict__ for magic methods and __getattr__ doesn’t work, but since we want to override them, we need to use this trick with proxy property.
It makes the class looking like the source object.

- **sublayer_position** – Position to insert the new layer.
Position should be less than len(layer.subLayerPaths).
Any other position will be treated as invalid index.
- **layer_identifier** – New layer path.
#### Returns
- Sublayer handle or None if sublayer_position is not valid or layer_identifier is empty or replaced layer is not existed.
### resolve_paths
Resolve all paths from References, Sublayers and AssetPaths of target layer based on source layer.
This function is used normally when you transfer the content from source layer to target layer that
are not in the same directory. So it needs to resolve all references so that they point to correct
location.
#### Parameters
- **base_layer** (`Sdf.Layer`) – Source layer that references in target layer based on.
- **target_layer** (`Sdf.Layer`) – Target layer to resolve.
- **store_relative_path** (`bool`) – True to store relative path, or False to store absolute path.
if relative path cannot be computed (like source layer and
target are not in the same domain), it will save absolute paths.
- **relative_to_base_layer** (`bool`) – True if the relative path is computed against the target_layer.
False otherwise.
- **copy_sublayer_offsets** (`bool`) – True to copy sublayer offsets and scales from base to target.
### set_custom_layer_name
Sets the custom name of layer, or clear it if name is empty or None.
The name is saved inside the custom data of layer and can only be
consumed by Kit application.
#### Parameters
- **layer** (`Layer`)
- **name** (`str`)
### transfer_layer_content
Transfer layer content from source layer to target layer with re-pathing all external
Dependencies.
### Parameters
- **source_layer** (`Sdf.Layer`) – Source layer handle.
- **target_layer** (`Sdf.Layer`) – Target layer handle.
- **copy_custom_data** (`bool`) – Whether copying layer metadata or not.
- **skip_sublayers** (`bool`) – Whether skipping to copy sublayers or not if `copy_custom_data` is True. | 10,080 |

Stops current live session or shows widget to join/leave session. If current session is empty, it will show the session start dialog. If current session is not empty, it will stop session directly or show stop session menu.
Parameters:
- **usd_context** – The current usd context to operate on.
- **stop_session_only** – If it’s true, it will ask user to stop session if session is not empty without showing merge options. If it’s false, it will show both leave and merge session options.
- **stop_session_forcely** – If it’s true, it will stop session forcely even if current sesison is not empty. Otherwise, it will show leave session or both leave and merge options that’s dependent on if stop_session_only is true or false.
