Why am I not getting events for a checkbox click in a treeview control?

Question

In my MFC dialog, i have a tree view control with checkboxes. Clicking the checkbox does not raise the NM_CLICK nor the TVN_SELCHANGED events, which I had hoped it would do.

How do I correctly determine when a checkbox is checked/unchecked in a tree view control?

Answer 1

Handle mouse click normally and in the handler identify the current item and then use TreeView_GetCheckState to get its checked state.

Answer 2

There is no notification of the click.
