classmethod getQtDesignerPluginInfo()[source]

isLedColorValid(name)[source]

Determines if the given color name is valid.

Parameters:: color (str) – the color
Returns:: True is the given color name is valid or False otherwise
Return type:: bool

ledColor

This property holds the led color

Access functions:

QLed.getLedColor()

QLed.setLedColor()

QLed.resetLedColor()

ledPattern

This property holds the led pattern name

Access functions:

QLed.getLedPatternName()

QLed.setLedPatternName()

QLed.resetLedPatternName()

resetLedPatternName()[source]: Resets the led pattern to leds/images256/led_{color}_{status}.png

setLedColor(color: str)[source]

Sets the led color

Parameters:: status (str) – the new color

setLedPatternName(name)[source]

Sets the led pattern name. Should be a string containing a path to valid images. The string can contain the keywords:

{status} - transformed to ‘on’ of ‘off’ according to the status

{color} - transformed to the current led color

Example: :leds/images256/led_{color}_{status}.png will be transformed to :leds/images256/led_red_on.png when the led status is True and the led color is red.

Parameters:: name (str) – new pattern
