Breaking out of loop / while with encoder

[kimbrussow]

I am using LcdMenu to control processing (led light strip / FastLED)
one of my SubMenus has the following:
ITEM_COMMAND("Pattern 1", {
Pat1();
}), << calls the function:
void Pat1()
{
do{
for (int i = 0; i < NUM_LEDS; i++) {
// for testing loop Serial.println("in loop");
leds[i] = CRGB::Yellow;
FastLED.show();
delay(100);
blah blah blah...
} while("get something from the encoder here"!= true);
}
Question: how to "get something from the encoder" to exit the do loop??
