◆ Leds

LedCollection Leds

get

The collection of LEDs that belong to this display widget

◆ AutoFlush

bool AutoFlush

getsetinherited

Whether this interface should automatically flush new values or not

◆ Parent

IFlushable Parent

getinherited

Gets or sets the parent flushable device (if it exists); if this property is set by this driver, it is expected that flushing the parent will also flush this device

This property is designed to make LED displays, which operate across groups of LEDs (and possibly groups of LED drivers), much more efficient to update. Many commonly-used LED drivers are shift registers that are chained together; since these cannot be individually addressed, any write to one must include a write to all the other ones. By properly setting the parent shift register in each chain, displays can optimize these updates.
