Açıklamalar

Verilen elementdeğerinin sayısı ne kadar büyüksevalue, ön planda görünme olasılığı element da o kadar yüksektir. Benzer şekilde, bir element görece düşüksevalueelement, büyük olasılıkla arka planda görünür. Örneğin, değeri 5 olan value bir element değeri 4 olan value bir element değerin üzerinde görünür ve bu da 3 değerinin üzerinde element görünür ve bu şekilde devam eder. Negatif değerlere izin verilir ve bu öncelik deseni devam eder.

Eşit ZIndex değerlere sahip bir Children koleksiyonun üyeleri, görsel ağaçta göründükleri sırayla işlenir. Koleksiyonun üyelerini Children yineleyerek bir çocuğun dizin konumunu belirleyebilirsiniz.
