enums

This module provides commonly used enumerations for the library. It also has a class implementing Enum-s with default values. All Enums below subclass it, meaning you can use their get_default() methods to get the globally set default value.

To modify defaults, use the defaults dictionary.

CenteringPolicy

    ALL = _auto()
    VERTICAL = _auto()
    HORIZONTAL = _auto()

DefaultEnum

An Enum class that can return its default value.

    RIGHT = 2
    """Align widget to the right edge."""

CENTER = 1 class-attribute

Center widget in the available width.

LEFT = 0 class-attribute

Align widget to the left edge.

RIGHT = 2 class-attribute

AUTO = 9999 class-attribute

NotImplemented

HIDE = 0 class-attribute

RESIZE = 2 class-attribute

Resize parent to fit with the new lines.

Note
