Grid Layout

The CGridLayout class inherits from GridLayout and extends its functionality by introducing additional properties.

For instance, let’s see an example of how CGridLayout enhances control of background color compared to standard one.

CarbonKivy

CGridLayout:
    bg_color: app.background_hover

Kivy

GridLayout:
    canvas.before:
        Color:
            rgba: app.background_hover
        SmoothRectangle:
            pos: self.pos
            size: self.size

Responsive Behavior

Use the responsive property to enable or disable the responsive behavior of the layout.

There are three tokens for responsive attribute:

cols
rows
both

Use the responsive_attr property to define the responsive attribute for the responsive behavior of the layout.

Usage

With any responsive attribute you have access to its minimum and maximum values.

Scaling - Breakpoints

Use the scale_width and scale_height properties to define the breakpoints for the responsive behavior of the layout.

Example

Let’s take an example of a grid layout with minimum columns 2, maximum columns 4 and responsive attribute as cols (default) with a breakpoint of dp(200).

CGridLayout:
    responsive: True
    min_cols: 2
    cols: 2 # default number of cols on start
    max_cols: 4
    scale_width: dp(200)
    adaptive: [False, True]

    CBoxLayout:
        orientation: 'vertical'
        size_hint: 1, None
        height: dp(300)
        bg_color: app.interactive

    CBoxLayout:
        orientation: 'vertical'
        size_hint: 1, None
        height: dp(300)
        bg_color: app.interactive

    CBoxLayout:
        orientation: 'vertical'
        size_hint: 1, None
        height: dp(300)
        bg_color: app.interactive

    CBoxLayout:
        orientation: 'vertical'
        size_hint: 1, None
        height: dp(300)
        bg_color: app.interactive
