Hovercard

The hover_card.root contains all the parts of a hover card.

The hover_card.trigger wraps the link that will open the hover card.

The hover_card.content contains the content of the open hover card.

rx.text(
    "Hover over the text to see the tooltip. ",
    rx.hover_card.root(
        rx.hover_card.trigger(
            rx.link("Hover over me", color_scheme="blue", underline="always"),
        ),
        rx.hover_card.content(
            rx.text("This is the tooltip content."),
        ),
    ),

Events when the Hovercard opens or closes

The on_open_change event is called when the open state of the hovercard changes. It is used in conjunction with the open prop, which is passed to the event handler.

class HovercardState(rx.State):
    num_opens: int = 0
    opened: bool = False

    def count_opens(self, value: bool):
        self.opened = value
        self.num_opens += 1


def hovercard_example():
    return rx.flex(
        rx.heading(f"Number of times hovercard opened or closed: {HovercardState.num_opens}"),
        rx.heading(f"Hovercard open: {HovercardState.opened}"),
        rx.text(
            "Hover over the text to see the tooltip. ",
            rx.hover_card.root(
                rx.hover_card.trigger(
                    rx.link("Hover over me", color_scheme="blue", underline="always"),
                ),
                rx.hover_card.content(
                    rx.text("This is the tooltip content."),
                ),
                on_open_change=HovercardState.count_opens,
            ),
        ),
        direction="column",
        spacing="3",
    )
