     A similar control with a fully native implementation for GTK+ and macOS
     as well is wxDataViewTreeCtrl.
 
+    @section treectrl_images Images in wxTreeCtrl
+
+    wxTreeCtrl inherits from wxWithImages classes providing the functions for
+    associating images with the control items. Each item refers to its image
+    using an index, which can possibly by wxWithImages::NO_IMAGE to indicate
+    that the item doesn't use any image at all, and the corresponding image is
+    taken either from the vector passed to wxWithImages::SetImages() or from
+    the image list passed to wxWithImages::SetImageList() or
+    wxWithImages::AssignImageList() functions.
+
+    In addition to normal images, handled with the methods mentioned above,
+    wxTreeCtrl also provides optional state images that may be used to indicate
+    some additional state of the item, e.g. checked or unchecked status. These
+    images can be set using SetStateImageList() and AssignStateImageList()
+    functions that behave in the same way as the corresponding methods of
+    wxWithImages.
+
+    Finally, in the generic version of this control (wxGenericTreeCtrl), also
+    provides SetButtonsImageList() and AssignButtonsImageList(), which can be
+    used to change the images used for the control buttons, used to expand or
+    collapse its branches. These methods are not available in the native wxMSW
+    and wxQt implementations.
+
+    @section treectrl_events Events
+
     To intercept events from a tree control, use the event table macros
     described in wxTreeEvent.
