Using Toolkit Pro 16.2.4.  Consider the following dialog box with 4 columns of 2 tree controls per column.  Separated as follows:
 
Column 0, Row 0 - CTreeCtrl
Column 0, Row 1 - CTreeCtrl with images
Column 1, Row 0 - CTreeCtrl with explorer theme  (i.e. Windows SetWindowTheme API)
Column 1, Row 1 - CTreeCtrl with images and explorer theme
Column 2, Row 0 - CXTPTreeCtrl
Column 2, Row 1 - CXTPTreeCtrlwith images
Column 3, Row 0 - CXTPTreeCtrl with explorer theme (i.e. CXTP SetExplorerTheme API)
Column 3, Row 1 - CXTPTreeCtrl with images and explorer theme
 
With checkboxes enabled, this is how CXTPTreeControl compares to the standard tree control:
 
 
 
Following CXTPTreeControl GUI issues are identified:
  1. As has been previously noted on this forum, CXTPTreeCtrl doesn't handle checkboxes properly when there isn't an image as well (Column 2, Row 0 and Column 3, Row 0).
  2. Not using the themed colors with SetExplorerTheme is enabled.  Compare column 3 with the correct colors in column 1.
  3. Nitpick but the expand/collapse icon is one pixel lower than the standard tree control.  Compare Columns 2,3 with Columns 0,1.
I can fix the GUI issues by using this class instead:
 
class CXTPTreeCtrlHack : public CXTPTreeCtrl
{
   virtual void DoPaint(CDC& dc, BOOL bInternal) { __super::DoPaint(dc, FALSE); }
};
 
But then you lose other CXTPTreeControl features.  Wanted to let you know.  Thanks.
