Comments

The SelectionArea property defines the area where selection changes occur.

The SelectionChange event occurs every time a selection change takes place.

By using the SelectionArea property, the application can specify which areas of an item can cause a selection change when clicked. If the defined area is clicked, the selection changes (Items.Selection). If an area of the item outside the defined area is clicked, only the current item (Items.Current) is changed. In addition, the Items.UpdateCurrentExpandCollapse defines whether the current item (Items.Current) is updated when the expand/collapse button is clicked.

When using a limited area, such as selSftTreeCellText1, which only changes selections when the cell text is clicked, it is preferable to visually indicate this using the selection style selectSftTreeCell1 (see Items.SelectStyle).

In a multiple selection tree control, the CONTROL key (in combination with directional keys) can be used to move the caret location without moving the current selection, unless the style selSftTreeAll is used, in which case the CONTROL key is ignored.
