\section{\class{wxEventBlocker}}\label{wxeventblocker}
|
|
|
|
This class is a special event handler which allows to discard
|
|
any event (or a set of event types) directed to a specific window.
|
|
|
|
Example:
|
|
|
|
\begin{verbatim}
|
|
|
|
{
|
|
// block all events directed to this window while
|
|
// we do the 1000 FuncWhichSendsEvents() calls
|
|
wxEventBlocker blocker(this);
|
|
|
|
for ( int i = 0; i < 1000; i++ )
|
|
FuncWhichSendsEvents(i);
|
|
|
|
} // ~wxEventBlocker called, old event handler is restored
|
|
|
|
// the event generated by this call will be processed
|
|
FuncWhichSendsEvents(0)
|
|
\end{verbatim}

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

\membersection{wxEventBlocker::\destruct{wxEventBlocker}}\label{wxeventblockerdtor}
|
|
|
|
\func{}{\destruct{wxEventBlocker}}{\void}
|
|
|
|
Destructor. The blocker will remove itself from the chain of event handlers for
|
|
the window provided in the constructor, thus restoring normal processing of
|
|
events.
|
|
|
|
|
|
\membersection{wxEventBlocker::Block}\label{wxeventblockerblock}
|
|
|
|
\func{void}{Block}{\param{wxEventType }{eventType}}
|
|
|
|
Adds to the list of event types which should be blocked the given \arg{eventType}.
