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:

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).
Not using the themed colors with SetExplorerTheme is enabled. Compare column 3 with the correct colors in column 1.
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.
