TShellTreeView.ShowButtons property

Declaration

property ShowButtons: ;

Description

Not described here; this is what TCustomTreeView.ShowButtons says of it:

Enables an expand/collapse (fold/unfold) icon for nodes with child nodes.

ShowButtons is a Boolean property which indicates whether an expand / collapse (fold) indicator is drawn for a tree node which has child nodes. The default value for the property is True, and causes an indicator to be drawn for qualified tree nodes.

ShowButtons is a convenience property; its value is read from and written to the Options for the control. When set to True, the value tvoShowButtons is included in the Options property. When set to False, tvoShowButtons is excluded from Options. Changing the value for the property causes the control to be redrawn.

ShowButtons is used during the paint process in the DoPaintNode method.
