TdxCustomTreeView.CustomSort(TdxTreeViewNodeCompareProc,NativeInt,Boolean) Method

Sorts tree nodes.

Declaration

function CustomSort(ASortProc: TdxTreeViewNodeCompareProc; AData: NativeInt; ARecurse: Boolean = True): Boolean;

Parameters

Name	Type	Description
ASortProc	TdxTreeViewNodeCompareProc	A custom comparison routine.
AData	NativeInt	Specifies a pointer to additional data for the custom comparison routine. This parameter is intended to be backward compatible with the TTreeView control.
ARecurse	Boolean	If True, the function sorts nodes at all nesting levels in the Tree View. If False, the function sorts only root level nodes.

Returns

Type	Description
Boolean	True if the sort operation is successful; otherwise, False.

Remarks

You can handle the Tree View’s OnCompare event to implement a custom node sorting algorithm.

Note

If you need to sort nodes in an individual branch, call the AlphaSort or CustomSort method of the branch’s root node.
