Remarks

Base class for toolkits that are used for asset editing (abstract)

Variables

  Type Name Description
Protected variable TSharedPtr< FWorkspaceItem > AssetEditorTabsCategory The base category that tabs are registered to, allows for child classes to register to the same point.
Protected variable bool bCheckDirtyOnAssetSave Whether only dirty assets should be prompted about on save - otherwise all edited assets will be prompted to the user for save/check-out
Protected variable TSharedPtr< FEditorModeTools > EditorModeManager The editor mode manager
Protected variable TArray< TSharedPtr< FLayoutExtender > > LayoutExtenders Array of layout extenders
Protected variable TWeakPtr< IToolkitHost > PreviousWorldCentricToolkitHost For standalone asset editing tool-kits that were switched from world-centric mode on the fly, this stores the toolkit host (level editor) that hosted this toolkit last.
Protected variable TSharedPtr< FTabManager > TabManager Controls our internal layout
