DataTransfer

from slint import DataTransfer

python

Represents some form of type-indexed possibly-lazy data transfer.

Used for accessing the platform clipboard and drag-and-drop APIs.

Properties

has_plaintext

has_plaintext: bool

True if this DataTransfer advertises a plaintext representation.

has_image

has_image: bool

True if this DataTransfer advertises an image representation.

user_data

user_data: Optional[object]

Application-internal user data attached to this DataTransfer. Use this when the drag-and-drop or clipboard operation stays inside the current Python application and you want to avoid serializing to plaintext or an image.

Reading returns the Python object previously assigned, or None if none was set (or the user data was set by a non-Python binding). Assigning None clears any previously attached Python user data.

Methods

set_plaintext

set_plaintext(text: str) -> None

Sets the plaintext representation of this DataTransfer. Calling this again overwrites the previous plaintext.

fetch_plaintext

fetch_plaintext() -> Optional[str]

Returns the plaintext representation of this DataTransfer, or None if no plaintext is available.

set_image

set_image(image: Image) -> None

Sets the image representation of this DataTransfer. Calling this again overwrites the previous image.

fetch_image

fetch_image() -> Optional[Image]

Returns the image representation of this DataTransfer, or None if no image is available.
