Column Button
The column button is displayed if both the column header panel and indicator panel are visible. The column button has no default functionality. You can however, handle the TreeListState.ColumnButtonPressed event to perform specific actions each time an end-user clicks the button.
The table below lists the main properties which affect the element’s appearance:
Appearance | The Tree Note: the appearance settings which specify the background and border colors are ignored if a Tree List is painted in Windows |
Custom Draw Event | The Tree |
Width | The Tree |
Visibility | The Tree |
Clicking | The Tree |
