Parameters

symName
Type: Symbol
The symbolic name of the tree view item to be toggled or the TreeViewItem object representing the tree view item to be toggled.
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.)

Return Value

Type: Logic
TRUE if successful; otherwise, FALSE.
