Introduction
In this blog, we will discuss Grid layout, how to implement it in python and the uses of grid layout.
Kivy is platform-agnostic, meaning it can operate on Android, iOS, Linux, Windows, and other operating systems. Kivy allows you to write code once and have it run across multiple platforms. Although it is mainly used to create Android applications, it may also be used to develop desktop applications.
Characteristics of Grid Layout
- The widget must always be positioned in a certain column or row. Each kid is automatically allocated a place in the children's list based on the layout setup and the child's index.
- Grid Layout must always have one of the input restrictions listed below: GridLayout.cols or GridLayout.rows. If no cols or rows are specified, the Layout will throw an exception.
- GridLayout organises children into a matrix. It splits the available space into columns and rows before adding widgets to a resulting "cell."
- The row and columns are the same as in a matrix, but we may alter the size of each grid here.
- The col default width and row default height attributes determine the initial size. By specifying the col force default or row force default properties, we may force the default size. This instructs the layout to disregard the width and size hint attributes of children and instead use the default size.
The first step in using a GridLayout would be to import it.
from kivy.uix.gridlayout import GridLayout
Background
You cannot specify insert a widget inside a specific column/row, unlike many other toolkits. The layout configuration and the kid's index in the children's list decide the position of each child automatically.
GridLayout.cols or GridLayout.rows are the two input constraints that must always be present in a GridLayout. The Layout will raise an exception if you don't specify cols or rows.
Column Width and Row Height
The column width/row height is calculated in three steps:
The col default width and row default height attributes determine the initial size. Use cols minimum or rows minimum to change the size of a single column or row.
The children's size hint x/size hint y are considered. If no widgets provide a size hint, the maximum size for all children is utilised.
Set the col force default or row force default attribute to force the default size. This instructs the layout to disregard the width and size hint attributes of children and instead use the standard size.
