1 | \section{\class{wxEventBlocker}}\label{wxeventblocker} |
2 | ||
3 | This class is a special event handler which allows to discard | |
4 | any event (or a set of event types) directed to a specific window. | |
5 | ||
6 | Example: | |
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} | |

45 | ||
46 | Constructs the blocker for the given window and for the given event type. | |
47 | If \arg{type} is \texttt{wxEVT\_ANY}, then all events for that window are | |
48 | blocked. You can call \helpref{Block}{wxeventblockerblock} after creation to | |
49 | add other event types to the list of events to block. | |
50 | ||
51 | Note that the \arg{win} window \textbf{must} remain alive until the | |
52 | wxEventBlocker object destruction. | |

56 | ||
57 | \func{}{\destruct{wxEventBlocker}}{\void} | |
58 | ||
59 | Destructor. The blocker will remove itself from the chain of event handlers for | |
60 | the window provided in the constructor, thus restoring normal processing of | |
61 | events. | |
62 | ||
63 | ||
64 | \membersection{wxEventBlocker::Block}\label{wxeventblockerblock} | |
65 | ||
66 | \func{void}{Block}{\param{wxEventType }{eventType}} | |
67 | ||
68 | Adds to the list of event types which should be blocked the given \arg{eventType}. | |
