Request Example
View SourceParameters
- symName
- Type: Symbol
The symbolic name of the tree view item to be expanded. - 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

Usual
TRUE if successful; otherwise, FALSE.
