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} | |

| 44 | \func{}{wxEventBlocker}{\param{wxWindow* }{win}, \param{wxEventType}{type = wxEVT\_ANY}} | |
| 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. | |
| 53 | ||
| 54 | ||
| 55 | \membersection{wxEventBlocker::\destruct{wxEventBlocker}}\label{wxeventblockerdtor} | |
| 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}. | |
