The following table shows the styles that are supported by Windows CE.
| Tree view style | Description |
|---|---|
| TVS_CHECKBOXES | Enables items in a tree view control to be displayed as check boxes. This style uses item state images to produce the check box effect. |
| TVS_DISABLEDRAGDROP | Prevents the tree view control from sending TVN_BEGINDRAG notification messages. |
| TVS_EDITLABELS | Enables the user to edit the labels of tree view items. |
| TVS_HASBUTTONS | Displays plus (+) and minus (-) buttons next to parent items. The user taps the buttons to expand or collapse a parent item's list of child items. To include buttons with items at the root of the tree view, you must also specify the TVS_LINESATROOT style. |
| TVS_HASLINES | Uses lines to show the hierarchy of items. |
| TVS_LINESATROOT | Uses lines to link items at the root of the tree view control. This value is ignored if the TVS_HASLINES control is not also specified. |
| TVS_RTLREADING | Causes text to be displayed from right-to-left (RTL). Usually, windows display text left-to-right (LTR). Windows can be mirrored to display languages such as Hebrew or Arabic that read RTL. Typically, tree-view text is displayed in the same direction as the text in its parent window. If TVS_RTLREADING is set, tree-view text reads in the opposite direction from the text in the parent window. |
| TVS_SHOWSELALWAYS | Uses the system highlight colors to draw the selected item. |
| TVS_SINGLEEXPAND | Specifies that when a new tree view item is selected, the selected item will automatically expand and the previously selected item will collapse. |
