Card

In plain words

A box with a border that keeps related things together, like a card on a table.

A rounded, bordered surface that groups content. title and actions add a header row; padding and width control its box.

Code

ui.card(
    pz.column([
        ui.muted("Pyzed draws the UI with Iced, in Rust."),
        pz.row([pz.hspace(), ui.button("Cancel", on_cancel, variant="ghost"),
                ui.button("OK", on_ok, variant="solid")], spacing=8),
    ], spacing=12),
    title="Card",
    actions=[ui.icon_button("ellipsis", on_menu, size="sm")],
    width=380,
)

When to use

• To group related content on a page: a summary, a form section, a dashboard tile.
• For a dialog over the UI use Modal.

Usage

import pyzed as pz
from pyzed import ui

ui.card(
    pz.column([
        ui.muted("Pyzed draws the UI with Iced, in Rust."),
        pz.row([pz.hspace(), ui.button("Cancel", on_cancel, variant="ghost"),
                ui.button("OK", on_ok, variant="solid")], spacing=8),
    ], spacing=12),
    title="Card",
    actions=[ui.icon_button("ellipsis", on_menu, size="sm")],
    width=380,
)

Variants

About these captures

Each capture is recorded by pyzed itself, off-screen at 2x, in One Dark or One Light to match this site’s theme, and cropped to the component so it shows at its real size. The pointer hovers, presses or types into it; a component that does not react to the pointer cycles through a few themes. With reduced motion you see the first frame. Open Code under a capture to see the snippet that draws it; free names such as on_save stand for your own callbacks.

Content

Content only

Code

ui.card(ui.muted("A bordered surface."), width=260)

title=

Code

ui.card(ui.muted("Three files changed."), title="Changes", width=260)

title=, actions=

Code

ui.card(ui.muted("Three files changed."), title="Changes",
        actions=[ui.icon_button("ellipsis", on_menu, size="sm")], width=260)

Padding

padding=8

Code

ui.card(ui.label("Compact"), padding=8)

padding=16

Code

ui.card(ui.label("Default"))

padding=28

Code

ui.card(ui.label("Roomy"), padding=28)

States and events

selected=True

Code

ui.card(ui.muted("Python app with a window"), title="Desktop app", on_press=on_press,
        selected=True, width=260)

footer=, elevated=True

Code

ui.card(ui.muted("3 files changed"), title="Commit", footer=[ui.button("Push", on_press)],
        elevated=True, width=260)

Events

Card has 1 event of its own, listed below. Like every widget it also has the 18 common events (click, double_click, right_click, mouse_enter, drag, key_down, resize…), attached with .on(...): see Events and Events of every component.

Event	Handler gets	When
on_press	()	Makes the whole card clickable.

Handler gets is what Pyzed passes to your callable: () means nothing. Any handler can also be a message (a value that is not callable), which goes to update().

Handling the events

The same events written three ways. Imperative: methods of the app change self. Declarative: the handlers produce messages and one update() decides. Functional: a pure function draws an immutable state and asks for changes with set_state(...). See Imperative, declarative and functional.

Imperative

class Plans(pz.App):
    def __init__(self):
        self.plan = "Pro"

    def view(self):
        return pz.row([
            ui.card(ui.muted(f"Plan {name}"), title=name, width=160, selected=name == self.plan,
                    on_press=lambda name=name: setattr(self, "plan", name))   # the whole card
            for name in ("Free", "Pro", "Team")
        ], spacing=8)

Declarative

from dataclasses import dataclass


@dataclass
class Choose:
    plan: str


class Plans(pz.App):
    plan = "Pro"

    def update(self, message):
        match message:
            case Choose(plan):
                self.plan = plan

    def view(self):
        return pz.row([ui.card(ui.muted(name), title=name, width=160, selected=name == self.plan,
                               on_press=Choose(name)) for name in ("Free", "Pro", "Team")], spacing=8)

Functional

from dataclasses import dataclass


@dataclass(frozen=True)
class State:
    plan: str = "Pro"


def plan_card(name, selected, choose):        # a small function component
    return ui.card(ui.muted(name), title=name, width=160, selected=selected, on_press=choose)


def view(state, set_state):
    return pz.row([plan_card(n, n == state.plan, lambda n=n: set_state(plan=n))
                   for n in ("Free", "Pro", "Team")], spacing=8)
