| Long | A long expression that indicates the amount, in pixels, that child items are indented relative to their parent items |
By default, the Indent property is set to 22 pixels. If the Indent property is set to 0, the child items will not be indented relative to their parent item, effectively aligning them with the parent in the hierarchy. Use HasLines and LinesAtRoot properties to show the hierarchy lines. Use the HasButtons property to define the +/- signs appearance. Use the TreeColumnIndex property to define the index of the column that displays the hierarchy. Use the InsertItem method to insert a child item. Use the InsertControlItem property to insert an ActiveX item. Use the IndentSelection method to change the parent of selected items, making them shallower if true or deeper if false in the hierarchy.
