-    An icon is a small rectangular bitmap usually used for denoting a
-    minimized application. It differs from a wxBitmap in always
-    having a mask associated with it for transparent drawing. On some platforms,
-    icons and bitmaps are implemented identically, since there is no real
-    distinction between
-    a wxBitmap with a mask and an icon; and there is no specific icon format on
-    some platforms (X-based applications usually standardize on XPMs for small
-    bitmaps
-    and icons). However, some platforms (such as Windows) make the distinction, so
-    a separate class is provided.

+    It differs from a wxBitmap in always having a mask associated with it for

+    separate class is provided.
+
+    @remarks
+    It is usually desirable to associate a pertinent icon with a frame.
+    Icons can also be used for other purposes, for example with wxTreeCtrl and wxListCtrl.
+    Icons have different formats on different platforms therefore separate icons
+    will usually be created for the different environments.
+    Platform-specific methods for creating a wxIcon structure are catered for,
+    and this is an occasion where conditional compilation will probably be required.
+    Note that a new icon must be created for every time the icon is to be used
+    for a new window. In Windows, the icon will not be reloaded if it has already
+    been used.
+    An icon allocated to a frame will be deleted when the frame is deleted.
+    For more information please see @ref overview_bitmap.
