| ### Here’s the information about the VH annotation: |
| |
| Each screenshot corresponds to a `.pkl` file with the same name, containing a list of dictionaries. Each dictionary includes the following keys: |
| |
| - **`"bounds_in_screen"`**: Defines the screen boundaries of the window, with values: |
| ```json |
| { |
| "left": windows.bounds_in_screen.left, |
| "right": windows.bounds_in_screen.right, |
| "bottom": windows.bounds_in_screen.bottom, |
| "top": windows.bounds_in_screen.top |
| } |
| ``` |
| - **`"window_id"`**: The unique identifier of the window. |
| - **`"window_layer"`**: The layer or z-index of the window. |
| - **`"window_type"`**: The type of the window. |
| - **`"tree"`**: A list containing dictionaries representing each element node in the window. |
| |
| Each node in the `"tree"` list includes: |
|
|
| - **`"bounds_in_screen"`**: The screen boundaries of the element node, with values: |
| ```json |
| { |
| "left": node.bounds_in_screen.left, |
| "right": node.bounds_in_screen.right, |
| "bottom": node.bounds_in_screen.bottom, |
| "top": node.bounds_in_screen.top |
| } |
| ``` |
| - **`"class_name"`**: The class name of the element. |
| - **`"content_description"`**: The content description of the element. |
| - **`"package_name"`**: The package name the element belongs to. |
| - **`"text_selection_start"`**: The start position of any text selection. |
| - **`"text_selection_end"`**: The end position of any text selection. |
| - **`"view_id_resource_name"`**: The resource name of the view ID. |
| - **`"window_id"`**: The window ID associated with the element. |
| - **`"is_enabled"`**: Boolean indicating if the element is enabled. |
| - **`"is_visible_to_user"`**: Boolean indicating if the element is visible to the user. |
| - **`"actions"`**: A list of action IDs available for the element, derived as `[action.id for action in node.actions]`. |
| - **`"child_ids"`**: A list of IDs for child elements, derived as `[child_id for child_id in node.child_ids]`. |
| - **`"depth"`**: The depth of the element within the hierarchy. |
| - **`"drawing_order"`**: The order in which the element is drawn within the window. |
