Editor Code Analysis

SVisualLogger is the core main slate widget.

SVisualLoggerFilters is the slate widget that holds the list of categories. Inside SVisualLoggerFilters::Construct FVisualLoggerFilters::Get().Categories is iterated to add all the categories as SVisualLoggerFilterWidget.

FVisualLoggerFilters::Initialize is called in FLogVisualizerModule::StartupModule. FVisualLoggerFilters::AddCategory and FVisualLoggerFilters::RemoveCategory is used to add/remove entries in the Categories array.

New categories are added by FVisualLoggerFilters::OnNewItemHandler, which is a callback set in FVisualLoggerFilters::Initialize on FVisualLoggerDBEvents::OnNewItem (stored in FVisualLoggerDatabase).

From what i gathered the flow is FVisualLoggerDatabase::AddItem → FVisualLoggerDBRow::AddItem → OnNewItem is broadcasted → FVisualLoggerFilters::OnNewItemHandler callback → FVisualLoggerFilters::AddCategory.
