Syntax

 VIRTUAL METHOD Collapse(
	lAll,
	lForceNotify
) AS USUAL CLIPPER

[ClipperCallingConventionAttribute(new string[] { ... })]
public virtual Usual Collapse(
	Usual lAll = default,
	Usual lForceNotify = default
)

lAll (Optional): Type: Usual
If lAll is TRUE(default = FALSE), the operation is done for the complete subtree of the specified item.
lForceNotify (Optional): Type: Usual
If lForceNotify is TRUE(default = FALSE), a notify message Window:TreeViewItemExpanding() and Window:TreeViewItemExpanded() is sent for each item whose expand state is changed. Generally windows will only send these messages when an item is first expanded. It depends on the TVIS_EXPANDEDONCE state. (see in Platform SDK the TVM_EXPAND Message for more details.)

Type: Usual
TRUE if successful; otherwise, FALSE.
