In order to process any event in the treeview, you may consider creating a callback function derived from control name.

 

  control add treeview name "myTreeview", hDlg, %controlMyTreeview, "", 5, 5, 100, 100

 

...

 

callback function myTreeview.OnCallBack()

select case callback_message

  case ...

  case ...

end select

end function

 

Anytime selection changes, this function will be called and you can reach for standard callback parameters, such as cbhndl, from it.

 

This way you can easily process any messages the treeview changes, on one place.
