A WTL tree control that supports Windows Vista style selection and multiple selection.


After quite a few requests, I thought I'd post this tree control that uses a similar selection drawing style to the list control I posted here: ListCtrl - A WTL list control with Windows Vista style item selection. For an added bonus, I've also included support for multiple-selection.

How to use CTreeCtrl

Simply use the tree control as you would the normal CTreeViewCtrl, however there are a couple of functions required to activate and retrieve multiple selections:

void ShowThemed( 
    BOOL bShowThemed = TRUE


Draw item selection themed.


  • bShowThemed - TRUE = Draw themed selection; FALSE = Classic mode.
void SetMultipleSelect( 
       BOOL bMultipleSelect


Turns on/off multiple selection.


  • bMultipleSelect - TRUE = Turn on multiple select.
void GetSelectedItems( 
    CSimpleArray < HTREEITEM >& aSelectedItems


Retrieves a list of selected tree items.


  • aSelectedItems - Reference to an array of HTREEITEM.


Any comments or suggestions are welcome.
