# `gradio_rich_textbox` PyPI - Version Gradio custom component for rich text input ## Installation ```bash pip install gradio_rich_textbox ``` ## Usage ```python import gradio as gr from gradio_rich_textbox import RichTextbox example = RichTextbox().example_inputs() demo = gr.Interface( lambda x:x, RichTextbox(), # interactive version of your component RichTextbox(), # static version of your component examples=[[example]], # uncomment this line to view the "example version" of your component ) if __name__ == "__main__": demo.launch() ``` ## `RichTextbox` ### Initialization
name type default description
value ```python typing.Union[str, typing.Callable, NoneType][ str, Callable, None ] ``` "" default text to provide in textbox. If callable, the function will be called whenever the app loads to set the initial value of the component.
placeholder ```python str | None ``` None placeholder hint to provide behind textbox.
label ```python str | None ``` None component name in interface.
every ```python float | None ``` None If `value` is a callable, run the function 'every' number of seconds while the client connection is open. Has no effect otherwise. Queue must be enabled. The event can be accessed (e.g. to cancel it) via this component's .load_event attribute.
show_label ```python bool | None ``` None if True, will display label.
scale ```python int | None ``` None relative width compared to adjacent Components in a Row. For example, if Component A has scale=2, and Component B has scale=1, A will be twice as wide as B. Should be an integer.
min_width ```python int ``` 160 minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first.
interactive ```python bool | None ``` None if True, will be rendered as an editable textbox; if False, editing will be disabled. If not provided, this is inferred based on whether the component is used as an input or output.
visible ```python bool ``` True If False, component will be hidden.
rtl ```python bool ``` False If True and `type` is "text", sets the direction of the text to right-to-left (cursor appears on the left of the text). Default is False, which renders cursor on the right.
elem_id ```python str | None ``` None An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles.
elem_classes ```python list[str] | str | None ``` None An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles.
render ```python bool ``` True If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later.
### Events | name | description | |:-----|:------------| | `change` | Triggered when the value of the RichTextbox 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. | | `input` | This listener is triggered when the user changes the value of the RichTextbox. | | `submit` | This listener is triggered when the user presses the Enter key while the RichTextbox is focused. | ### 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, text. - **As input:** Should return, function output to postprocess. ```python def predict( value: str | None ) -> str | None: return value ```
