When I create a Slate Compound Widget from the engine (4.4.1 built from Source) I encounter the following two bugs:
- The file created is called SMyCompoundWidget.h, per Unreal guidelines the S should be omitted.
- The header file is missing a
#include Slate.h
for the code to compile
These can be observed by pressing File>Add Code and choosing to create a new Slate Widget (second option from the bottom).
