Vadim Zeitlin 391555d341 Fix data race when using wxTheApp::m_handlersWithPendingEvents
Appending to the vector from another thread could reallocate it, making
access to its first element from the main thread invalid and resulting
in probably very hard to diagnose crashes.

Fix this by storing the handler in a local variable before releasing the
critical section protecting the vector. This still relies on the handler
not being deleted, but this was the case before too and shouldn't happen
and, most importantly, there doesn't seem to be anything we can do about
it if it does.

Thanks TSAN for the warning.

About

wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.

wxWidgets Logo

wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at https://www.wxwidgets.org/ and read its documentation online at https://docs.wxwidgets.org/

Licence

wxWidgets licence is a modified version of LGPL explicitly allowing not distributing the sources of an application using the library even in the case of static linking.

Building

For building the library, please see platform-specific documentation under docs/<port> directory, e.g. here are the instructions for wxGTK, wxMSW and wxOSX.

If you're building the sources checked out from Git, and not from a released version, please see these additional Git-specific notes.

Further information

If you are looking for community support, you can get it from

Commercial support is also available.

Finally, keep in mind that wxWidgets is an open source project collaboratively developed by its users and your contributions to it are always welcome. Please check our guidelines if you'd like to do it.

Have fun!
