### Events
| name | description |
|:-----|:------------|
| `select` | Event listener for when the user selects or deselects the DownloadGallery. Uses event data gradio.SelectData to carry `value` referring to the label of the DownloadGallery, and `selected` to refer to state of the DownloadGallery. See EventData documentation on how to use this event data |
| `upload` | This listener is triggered when the user uploads a file into the DownloadGallery. |
| `change` | Triggered when the value of the DownloadGallery changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See `.input()` for a listener that is only triggered by user input. |
| `toggle_favorite` | Triggered when the user clicks on the favorite icon of an image |
### User function
The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).
- When used as an Input, the component only impacts the input signature of the user function.
- When used as an output, the component only impacts the return signature of the user function.
The code snippet below is accurate in cases where the component is used as both an input and an output.
- **As output:** Is passed, passes the list of images as a list of (image, caption) tuples, or a list of (image, None) tuples if no captions are provided (which is usually the case). The image can be a `str` file path, a `numpy` array, or a `PIL.Image` object depending on `type`.
- **As input:** Should return, expects the function to return a `list` of images, or `list` of (image, `str` caption) tuples. Each image can be a `str` file path, a `numpy` array, or a `PIL.Image` object.
```python
def predict(
value: list[tuple[str, str | None, bool | None]]
| list[tuple[PIL.Image.Image, str | None, bool | None]]
| list[tuple[numpy.ndarray, str | None, bool | None]]
| None
) -> list[
numpy.ndarray
| PIL.Image.Image
| pathlib.Path
| str
| tuple[
numpy.ndarray
| PIL.Image.Image
| pathlib.Path
| str,
str,
]
| tuple[
numpy.ndarray
| PIL.Image.Image
| pathlib.Path
| str,
str,
bool,
]
]
| None:
return value

If False, icon does not appear. If set to None (default behavior), then the icon appears if this Gradio app is launched on Spaces, but not otherwise.</td>\n</tr>\n</tbody></table>\n\n\n### Events\n\n| name | description |\n|:-----|:------------|\n| `select` | Event listener for when the user selects or deselects the DownloadGallery. Uses event data gradio.SelectData to carry `value` referring to the label of the DownloadGallery, and `selected` to refer to state of the DownloadGallery. See EventData documentation on how to use this event data |\n| `upload` | This listener is triggered when the user uploads a file into the DownloadGallery. |\n| `change` | Triggered when the value of the DownloadGallery changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See `.input()` for a listener that is only triggered by user input. |\n| `toggle_favorite` | Triggered when the user clicks on the favorite icon of an image |\n\n\n\n### User function\n\nThe impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).\n\n- When used as an Input, the component only impacts the input signature of the user function.\n- When used as an output, the component only impacts the return signature of the user function.\n\nThe code snippet below is accurate in cases where the component is used as both an input and an output.\n\n- **As output:** Is passed, passes the list of images as a list of (image, caption) tuples, or a list of (image, None) tuples if no captions are provided (which is usually the case). The image can be a `str` file path, a `numpy` array, or a `PIL.Image` object depending on `type`.\n- **As input:** Should return, expects the function to return a `list` of images, or `list` of (image, `str` caption) tuples. Each image can be a `str` file path, a `numpy` array, or a `PIL.Image` object.\n\n ```python\n def predict(\n value: list[tuple[str, str | None, bool | None]]\n | list[tuple[PIL.Image.Image, str | None, bool | None]]\n | list[tuple[numpy.ndarray, str | None, bool | None]]\n | None\n ) -> list[\n numpy.ndarray\n | PIL.Image.Image\n | pathlib.Path\n | str\n | tuple[\n numpy.ndarray\n | PIL.Image.Image\n | pathlib.Path\n | str,\n str,\n ]\n | tuple[\n numpy.ndarray\n | PIL.Image.Image\n | pathlib.Path\n | str,\n str,\n bool,\n ]\n ]\n | None:\n return value\n ```\n \n",
