Request Example
View SourceParameters
- symName (Optional)
- Type: Usual
The symbolic name of the tree view item to be toggled or the TreeViewItem object representing the tree view item to be toggled. - 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.)
