Açıklamalar

BehaviorService oluşturulduğunda, tasarımcı çerçevesinin üzerine saydam bir pencere ekler. BehaviorService daha sonra bu pencereyi kullanarak nesneler olarak adlandırılan Glyph kullanıcı arabirimi öğelerini işleyebilir ve tüm fare iletilerini yakalayabilir. Bu şekilde, BehaviorService tasarımcı davranışını denetleyebilirsiniz.

BehaviorService sınıfı, nesnelerin gönderilebileceği Behavior bir davranış yığınını destekler. Saydam pencere aracılığıyla bir ileti kesildiğinde, BehaviorService iletiyi yığının en üstündekine Behavior gönderebilir. Bu, şu anda gönderilen Behavioröğesine bağlı olarak farklı kullanıcı arabirimi modlarını etkinleştirir. BehaviorService, seçim kenarlıkları, boyutlandırma tutamaçları ve akıllı etiketler gibi tüm Glyph nesneleri işlemek için kullanılır. , BehaviorService ek çizgi kullanma, sürükleme ve seçme gibi birçok tasarım zamanı davranışını da denetler.
