Parameters

symName

Type: Symbol
The symbolic name of the tree view item to be collapsed.

lRemoveChildItems

Type: Logic
A logical value indicating whether child tree view items of the specified item will be removed when the item is collapsed. If omitted, the default is FALSE.

lAll

Type: Logic
If lAll is TRUE(default = FALSE), the operation is done for the complete subtree of the specified item.

lForceNotify

Type: Logic
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.)
