Added Delete member to wxStringHashTable in order to implement
wxHelpProvider::RemoveHelp, which is now called from ~wxWindowBase. Without cleaning up the hash tables, reused window addresses will cause the CS help to fail rather comically over time. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@15754 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

<h3><a name="exceptions">How to use C++ exceptions with wxWindows?</a></h3>
|
||||
|
||||
wxWindows library itself is unfortunately <i>not</i> exception-safe (as its
|
||||
initial version predates, by far, the addition of the exceptions to the C++
|
||||
language). However you can still use the exceptions in your own code and use
|
||||
the other libraries using the exceptions for the error reporting together with
|
||||
wxWindows.
|
||||
|
||||
<p>
|
||||
There are a few issues to keep in mind, though:
|
||||
<ul>
|
||||
<li>You shouldn't let the exceptions propagate through wxWindows code,
|
||||
in particular you should always catch the exceptions thrown by the
|
||||
functions called from an event handler in the handler itself and not
|
||||
let them propagate upwards to wxWindows.
|
||||
|
||||
<li>You may need to ensure that the compiler support for the exceptions is
|
||||
enabled as, considering that wxWindows itself doesn't use the
|
||||
exceptions and turning their support on results in the library size
|
||||
augmentation of 10% to 20%, it is turned off by default for a few
|
||||
compilers. Moreover, for gcc (or at least its mingw version) you must
|
||||
also turn on the RTTI support to be able to use the exceptions, so you
|
||||
should use <tt>--disable-no_rtti --disable-no_exceptions</tt> options
|
||||
when configuring the library (attention to the double negation).
|
||||
