Here is the call graph for this function:

void StatusIndicator::setValue

(

QVariant

v

)

[protected]

Sets the value of the indicator. This will be used by the dynamic indicators to change their appearance based on some value. The type of the value is determined by the indicator type. For indicators that display an image from a list of images, the value is a float 0 to 1 which is used to determine the used image. For indicators that display text, the value is the string to display.

    currentValue = v;
    if (modelUpdatesEnabled) {
        model()->setValue(v);
    }
}
