TreeView Control - TreeView Styles

James Crowley

TreeView Styles

The TreeView control has a number of properties that changes the way it looks. A few are discussed below.

Indentation - Sets the amount distance between a node and its children.

BorderStyle - Sets the style of the border. Either ccNone (no border) or ccFixedSingle (single border)

Appearance - Sets the appearance of the TreeView control. Either cc3D (3D style appearance) or ccFlat (flat appearance)

LineStyle - Sets the line style. Either tvwRootLines (lines come from the very top) or tvwTreeLines (lines come from each item at the top level). The best way to see this is to try it at home!

Style - Sets the treeview style. Can be set to one of the following:

tvwTextOnly - Only text is displayed. No treelines, images or plus/minus's (expand/shrink) are displayed
tvwPictureText - Text and pictures are displayed. No treelines or plus/minus's.
tvwPlusMinusText - Text and plus/minus's are displayed. No treelines or images.
tvwPlusPictureText - Text, plus/minus's and images are displayed. No treelines.
tvwTreelinesText - Text and treelines are displayed. No images or plus/minus's.
tvwTreelinesPictureText - Text, images and treelines are displayed. No plus/minus's
tvwTreelinesPlusMinusText - Text, treelines and plus/minus's are displayed. No images
tvwTreelinesPlusMinusPictureText - Text, treelines, plus/minus's and images are all displayed.

Please note that you need to assign an image to each item for an image to be displayed.
