+
+    There are several different types of tools you can add to a toolbar.
+    These types are controlled by the ::wxItemKind enumeration.
+
+    Note that many methods in wxToolBar such as wxToolBar::AddTool return a
+    @c wxToolBarToolBase* object.
+    This should be regarded as an opaque handle representing the newly added
+    toolbar item, providing access to its id and position within the toolbar.
+    Changes to the item's state should be made through calls to wxToolBar methods,
+    for example wxToolBar::EnableTool.
+    Calls to @c wxToolBarToolBase methods (undocumented by purpose) will not change
+    the visible state of the item within the the tool bar.

+    system-wide colours. If you use more than 16 colours in your tool bitmaps,
