Left
Right
Center
On non-AmigaOS systems this attribute is only supported for the dataview
backend. When creating a treeview and Treeviewcolumn.Align is
set to a value other than Left
, RapaGUI will automatically switch to the
dataview backend. If you don't specify this attribute at creation time
but want to set it later using moai.Set(), you have to
explicitly request a dataview widget by setting the Treeview.ForceMode
attribute.
