Is the TVS_CHECKBOXES style supported by the CXTShellTree class? Currently the tree view will display correctly until the mouse is moved over the items and then the checkboxes disappear.

The GUI_Explorer sample can be modified to show the effect...

if( !m_shellTree.Create(WS_VISIBLE | TVS_CHECKBOXES, CRect(0,0,0,0), this, IDC_TREE_VIEW))

I reported this as a bug just recently, confirmed by codejock. Replace as follows and rebuild the codejock libraries:

In XTTreeBase.cpp, replace

#define TVIS_UNDERLINE 0x1000

with

#define TVIS_UNDERLINE 0x10000

Also, unrelated bug that may cause your tree control to not be populated...

In CXTShellTreeBase::InitializeTree, replace

if (!m_pTreeCtrl->ModifyStyle(NULL, dwStyle)) {

return FALSE;

}

with

m_pTreeCtrl->ModifyStyle(NULL, dwStyle);
