+         this message dialog after the current event handler completes.
+
+         The method being called must be the method of the object on which

-    When a keyboard context menu button is pressed on Windows, a right-click event

-    for mouse right-down events.
+    Notice that the exact sequence of mouse events is different across the

+    @section sec_delayed_action Delayed Action Mechanism
+
+    wxIdleEvent can be used to perform some action "at slightly later time".
+    This can be necessary in several circumstances when, for whatever reason,
+    something can't be done in the current event handler. For example, if a
+    mouse event handler is called with the mouse button pressed, the mouse can
+    be currently captured and some operations with it -- notably capturing it
+    again -- might be impossible or lead to undesirable results. If you still
+    want to capture it, you can do it from @c wxEVT_IDLE handler when it is
+    called the next time instead of doing it immediately.
+
+    This can be achieved in two different ways: when using static event tables,
+    you will need a flag indicating to the (always connected) idle event
+    handler whether the desired action should be performed. The originally
+    called handler would then set it to indicate that it should indeed be done
+    and the idle handler itself would reset it to prevent it from doing the
+    same action again.
+
+    Using dynamically connected event handlers things are even simpler as the
+    original event handler can simply wxEvtHandler::Connect() or
+    wxEvtHandler::Bind() the idle event handler which would only be executed
+    then and could wxEvtHandler::Disconnect() or wxEvtHandler::Unbind() itself.
