I wanna make dialogue, but when i create widgets with button from c++, this widgets are created, but doesn’t exist on vieport. When i tried add this widget from bp, it’s exists. What i mean. Function AddChildToVerticalBox works as it should, but it doesn’t show its child widgets, which were created in c++. How can i solve this prblem?
