Columns

Columns control the way items and their subitems are displayed in report view. Each column has a title and width and is associated with a specific subitem (subitem zero is the item's icon and label). The attributes of a column are defined by an LV_COLUMN structure.

To add a column to a list view control, use the LVM_INSERTCOLUMN message. To delete a column, use the LVM_DELETECOLUMN message. You can retrieve and change the properties of an existing column by using the LVM_GETCOLUMN and LVM_SETCOLUMN messages.

To retrieve or change a column's width, use the LVM_GETCOLUMNWIDTH and LVM_SETCOLUMNWIDTH messages.

Unless the LVS_NOCOLUMNHEADER window style is specified, column headers appear in report view. The user can click a column header, causing an LVN_COLUMNCLICK notification message to be sent to the parent window. Typically, the parent window sorts the list view control by the specified column when this clicking occurs. The user can also drag the column guides between the headers to size the columns.
