PageLayout

_images/pagelayout.gif

The PageLayout class is used to create a simple multi-page layout, in a way that allows easy flipping from one page to another using borders.

PageLayout does not currently honor the size_hint, size_hint_min, size_hint_max, or pos_hint properties.

New in version 1.8.0.

Example:

PageLayout:
    Button:
        text: 'page1'
    Button:
        text: 'page2'
    Button:
        text: 'page3'

Transitions from one page to the next are made by swiping in from the border areas on the right or left hand side. If you wish to display multiple widgets in a page, we suggest you use a containing layout. Ideally, each page should consist of a single layout widget that contains the remaining widgets on that page.

class kivy.uix.pagelayout.PageLayout(**kwargs)[source]

Bases: kivy.uix.layout.Layout

PageLayout class. See module documentation for more information.

border

The width of the border around the current page used to display the previous/next page swipe areas when needed.

border is a NumericProperty and defaults to 50dp.

do_layout(*largs)[source]

This function is called when a layout is called by a trigger. If you are writing a new Layout subclass, don’t call this function directly but use _trigger_layout() instead.

The function is by default called before the next frame, therefore the layout isn’t updated immediately. Anything depending on the positions of e.g. children should be scheduled for the next frame.

New in version 1.0.8.
