Responsive

In plain words

Changes the layout depending on how much room there is, like a phone versus a monitor.

Calls function(width, height) with the space it really gets and shows what it returns, so the layout can adapt: hide a sidebar when the window is narrow, change the number of columns…

Code

box = lambda text, w=90, h=44: pz.container(ui.label(text), center=True, width=w, height=h, bg=pz.theme.current().element, radius=6)
pz.container(pz.responsive(lambda w, h: pz.center(pz.column([
    ui.muted(f"{w:.0f} × {h:.0f} px available"),
    pz.row([box("1"), box("2"), box("3"), box("4")], spacing=8) if w > 400 else
    pz.column([box("1"), box("2")], spacing=8),
], spacing=10, align="center"))), width=480, height=150)

When to use

• For layouts that must work both in a small and a large window.

Usage

import pyzed as pz
from pyzed import ui

box = lambda text, w=90, h=44: pz.container(ui.label(text), center=True, width=w, height=h, bg=pz.theme.current().element, radius=6)
pz.container(pz.responsive(lambda w, h: pz.center(pz.column([
    ui.muted(f"{w:.0f} × {h:.0f} px available"),
    pz.row([box("1"), box("2"), box("3"), box("4")], spacing=8) if w > 400 else
    pz.column([box("1"), box("2")], spacing=8),
], spacing=10, align="center"))), width=480, height=150)

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.

Available width

The same code, given two widths: the layout changes by itself.

width=200

Code

box = lambda text, w=90, h=44: pz.container(ui.label(text), center=True, width=w, height=h, bg=pz.theme.current().element, radius=6)
pz.container(pz.responsive(lambda w, h: pz.row([box("1"), box("2"), box("3")], spacing=8)
             if w > 300 else pz.column([box("1"), box("2")], spacing=8)), width=200, height=110)

width=400

Code

box = lambda text, w=90, h=44: pz.container(ui.label(text), center=True, width=w, height=h, bg=pz.theme.current().element, radius=6)
pz.container(pz.responsive(lambda w, h: pz.row([box("1"), box("2"), box("3")], spacing=8)
             if w > 300 else pz.column([box("1"), box("2")], spacing=8)), width=400, height=60)

Events

Responsive has no events of its own: it shows what you give it. 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.
