DECLARE_DELEGATE_OneParam() [1/2]

template<typename ArgumentType >

ArgumentType ArgumentType TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_OneParam	(	FOnMouseButtonDoubleClick	,
		ArgumentType
	)

param: The item that was double-clicked on Called when the user double-clicks on an item in a tree or list Invoked when someone clicks on a hyperlink.

DECLARE_DELEGATE_OneParam() [2/2]

template<typename ArgumentType >

TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_OneParam	(	FOnRefreshRow	,
		ArgumentType
	)

A delegate to be invoked to update an existing item (or its containing widget) when the owning view is invalidated.

DECLARE_DELEGATE_RetVal_OneParam() [1/2]

template<typename ArgumentType >

TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_RetVal_OneParam	(	FString	,
		FOnItemToString_Debug	,
		ArgumentType
	)

Useful for debugging issues with table views.

DECLARE_DELEGATE_RetVal_OneParam() [2/2]

template<typename ArgumentType >

TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_RetVal_OneParam	(	TSharedRef< SWidget >	,
		FOnGenerateWidget	,
		ArgumentType
	)

A delegate type for OnGenerateWidget handler. Given a data item, the handler should return a Widget visualizing that item

DECLARE_DELEGATE_RetVal_TwoParams()

template<typename ArgumentType >

TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_RetVal_TwoParams	(	TSharedRef< class ITableRow >	,
		FOnGenerateRow	,
		ArgumentType	,
		const TSharedRef< class STableViewBase > &
	)

The advanced version of OnGenerateWidget. You are given the reference to the owning list/tree and asked to return the appropriate container widget.

DECLARE_DELEGATE_TwoParams() [1/4]

template<typename ArgumentType >

ArgumentType TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_TwoParams	(	FOnExpansionChanged	,
		ArgumentType	,
		bool
	)

param: The newly selected value Called when the user clicks on an item in a tree or list

DECLARE_DELEGATE_TwoParams() [2/4]

template<typename ArgumentType >

TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_TwoParams	(	FOnItemScrolledIntoView	,
		ArgumentType	,
		const TSharedPtr< ITableRow > &
	)

A delegate to be invoked when an item has come into view after it was requested to come into view. A delegate for the OnGetChildren handler. Given a data item, populate an output array with its children if it has any.

DECLARE_DELEGATE_TwoParams() [3/4]

template<typename ArgumentType >

TSlateDelegates< ArgumentType >::DECLARE_DELEGATE_TwoParams	(	FOnSelectionChanged	,
		ArgumentType	,
		ESelectInfo::Type
	)

A delegate type invoked when a selection changes somewhere. A delegate type to control if a item is selectable or navigable.

DECLARE_DELEGATE_TwoParams() [4/4]

		ArgumentType	,
		bool
	)

A delegate for the OnSetExpansionRecursive handler. Given a data item, recursively expand/collapse its children.
