Bases: QtWidgetElement[QWidget]

Grid layout widget for rendering children on a 2D rectangular grid.

• Underlying Qt Layout QGridLayout

Grid Layout Element.

Props

All props for QtWidgetElement plus:

Parameters:

• layout (str) – Declaration of layout as described below.

• key_to_code (Optional[Mapping[str, str]]) – Optional Mapping from Element key to a single character representing that child in the layout string.

Usage

Children will be laid out according to the layout argument. Each child is assigned a character code (by default, the first character of the key; this can be changed via the key_to_code prop). The layout argument describes pictorially where the child should be laid out. For example:

aabc
aabd
effg

describes a layout of 7 children (labeled a to g) in a 3x4 grid. Child a occupies the top left 2x2 portion of the grid, child b occupies a 2x1 portion of the grid starting from the third column of the first row, etc.

You can also leave certain spots empty using ‘_’:

aa__
aabc
