traitsui.toolkit_traits module

traitsui.toolkit_traits.ColorTrait(*args, **traits)

Returns a trait whose value is a GUI toolkit-specific color.

A number of different values are accepted for setting the value, including:

• tuples of the form (r, g, b) and (r, g, b, a)

• strings which match standard color names

• strings of the form “(r, g, b)” and “(r, g, b, a)”

• integers whose hex value is of the form 0xRRGGBB

• toolkit-specific color classes

Tuple values are expected to be in the range 0 to 255.

Exact behaviour (eg. precisely what values are accepted, and what the “standard” color names are) is toolkit-dependent.

The default value is white. The default editor is a ColorEditor.

Parameters:

• default (color) – The default color for the trait.

• allow_none (bool) – Whether to allow None as a value.

• **metadata – Trait metadata to be passed through.

traitsui.toolkit_traits.FontTrait(*args, **traits)

Returns a trait whose value is a GUI toolkit-specific font.

This trait accepts either a toolkit-specific font object, or a string containing a font description. The string description can contain:

• a font name or family. The following generic names are understood: “default”, “decorative”, “roman”, “script”, “swiss”, and “modern”.

• a size, in points.

• a style, which is one of: “slant” or “italic”

• a weight, which is one of: “light” or “bold”

• whether the font is underlined, indicated by the inclusion of “underlined”.

Where values aren’t supplied, the application defaults will be used instead.

The default value is the application default font, which is toolkit and platform dependent. The default editor is FontEditor.

Parameters:

**metadata – Trait metadata to be passed through.

traitsui.toolkit_traits.RGBColorTrait(*args, **traits)

Returns a trait whose value is a RGB tuple with values from 0 to 1.

A number of different values are accepted for setting the value, including:

• tuples of the form (r, g, b) with values from 0.0 to 1.0

• strings which match standard color names

• integers whose hex value is of the form 0xRRGGBB

The default value is (1.0, 1.0, 1.0). The default editor is a RGBColorEditor.

Parameters:

**metadata – Trait metadata to be passed through.
