WkColumnView

The WkColumnView class defines a single column in an WkTableWidgetView or WkColumnarListBoxView widget. In addition to details about the look and feel of the column, it also provides get and set selectors which the application may use to specify the cell value for an item in that column and a list selector for specifying a dropdown list of values for a cell. The cell values may be further augmented through a cell value event. The column also provides events to notify the application when a cell is about to be edited and when the edit is about to end.
