Hello thinBasic users,
I can't figure it out. What callback message is sent when someone clicks a check box used inside the tree view control? (%TVS_CHECKBOXES)

%TVS_CHECKBOXES is the style to be used in order to have checkbox in treview

Not sure about what message is sent when checkbox change but I'm pretty sure it will be in form of notification message %WM_NOTIFY.
At that point my idea is that you can check %TVN_ITEMCHANGED notification and CBLPARAM should contain a PTR to a NMTVITEMCHANGE (http://msdn.microsoft.com/en-us/library/bb773425(v=VS.85).aspx) structure.

Never tested. If I will have some spare time I will try to check if it works as expected
