1\section{\class{wxEventBlocker}}\label{wxeventblocker}
2
3This class is a special event handler which allows to discard
4any event (or a set of event types) directed to a specific window.
5
6Example:
7
8\begin{verbatim}
9
10 {
11 // block all events directed to this window while
12 // we do the 1000 FuncWhichSendsEvents() calls
13 wxEventBlocker blocker(this);
14
15 for ( int i = 0; i < 1000; i++ )
16 FuncWhichSendsEvents(i);
17
18 } // ~wxEventBlocker called, old event handler is restored
19
20 // the event generated by this call will be processed
21 FuncWhichSendsEvents(0)
22\end{verbatim}

48\func{}{wxEventBlocker}{\param{wxWindow* }{win}, \param{wxEventType}{type = wxEVT\_ANY}}
49
50Constructs the blocker for the given window and for the given event type.
51If \arg{type} is \texttt{wxEVT\_ANY}, then all events for that window are
52blocked. You can call \helpref{Block}{wxeventblockerblock} after creation to
53add other event types to the list of events to block.
54
55Note that the \arg{win} window \textbf{must} remain alive until the
56wxEventBlocker object destruction.

60
61\func{}{\destruct{wxEventBlocker}}{\void}
62
63Destructor. The blocker will remove itself from the chain of event handlers for
64the window provided in the constructor, thus restoring normal processing of
65events.

72Adds to the list of event types which should be blocked the given \arg{eventType}.
