Detailed Description

LED widget.

A LED representation, with two states. The colors for both on and off states can be changed. When the on color is specified, the off color is automatically calculated as a darker shade of the on color

Negate allows to switch state, in case the input signal represents the opposite.

Any color can be used. A base image is used to represent the LED, and the widget replaces the color of the image by the ones indicated in the widgets properties.

Property Documentation

colorOff

QColor QeLed::colorOff

readwrite

Color to be used when the LED is turned off.

If no color is manually set, the widget will calculate a darker version of the colorOn.

@accessors colorOff(), setColorOff(QColor)
