\membersection{wxApp::wxApp}
\func{void}{wxApp}{\void}
Constructor. Called implicitly with a definition of a wxApp object.
+
\membersection{wxApp::\destruct{wxApp}}
\func{void}{\destruct{wxApp}}{\void}
Destructor. Will be called implicitly on program exit if the wxApp
object is created on the stack.
+
\membersection{wxApp::argc}\label{wxappargc}
\member{int}{argc}
Number of command line arguments (after environment-specific processing).
+
\membersection{wxApp::argv}\label{wxappargv}
\member{char **}{argv}

going to be processed at all (for the latter one).
+
\membersection{wxApp::GetAppName}\label{wxappgetappname}
\constfunc{wxString}{GetAppName}{\void}
wxWindows sets this to a reasonable default before
calling \helpref{wxApp::OnInit}{wxapponinit}, but the application can reset it at will.
+

\membersection{wxApp::GetExitOnFrameDelete}\label{wxappgetexitonframedelete}
-\constfunc{bool}{GetExitFrameOnDelete}{\void}
+\constfunc{bool}{GetExitOnFrameDelete}{\void}
Returns true if the application will exit when the top-level window is deleted, false
otherwise.

\constfunc{wxString}{GetVendorName}{\void}
Returns the application's vendor name.
+
\membersection{wxApp::ExitMainLoop}\label{wxappexitmainloop}
\func{void}{ExitMainLoop}{\void}
You should normally exit the main loop (and the application) by deleting
the top window.
-\membersection{wxApp::Initialized}\label{wxappinitialized}
-
-\func{bool}{Initialized}{\void}
-
-Returns true if the application has been initialized (i.e. if\rtfsp
-\helpref{wxApp::OnInit}{wxapponinit} has returned successfully). This can be useful for error
-message routines to determine which method of output is best for the
-current state of the program (some windowing systems may not like
-dialogs to pop up before the main loop has been entered).

-\membersection{wxApp::OnExit}\label{wxapponexit}
-
-\func{int}{OnExit}{\void}
-
-Provide this member function for any processing which needs to be
-done as the application is about to exit. OnExit is called after
-destroying all application windows and controls, but before
-wxWindows cleanup.

+\membersection{wxApp::OnExit}\label{wxapponexit}
+
+\func{virtual int}{OnExit}{\void}
+
+Override this member function for any processing which needs to be
+done as the application is about to exit. OnExit is called after
+destroying all application windows and controls, but before
+wxWindows cleanup. Note that it is not called at all if
+\helpref{OnInit}{wxapponinit} failed.
+
+The return value of this function is currently ignored, return the same value
+as returned by the base class method if you override it.

\membersection{wxApp::OnInit}\label{wxapponinit}
\func{bool}{OnInit}{\void}
This must be provided by the application, and will usually create the
application's main window, optionally calling
-\helpref{wxApp::SetTopWindow}{wxappsettopwindow}.
+\helpref{wxApp::SetTopWindow}{wxappsettopwindow}. You may use
+\helpref{OnExit}{wxapponexit} to clean up anything initialized here, provided
+that the function returns \true.
Notice that if you want to to use the command line processing provided by
wxWindows you have to call the base class version in the derived class
OnInit().
-Return true to continue processing, false to exit the application.
+Return \true to continue processing, \false to exit the application
+immediately.

+
+\membersection{wxApp::OnRun}\label{wxapponrun}
+
+\func{virtual int}{OnRun}{\void}
+
+This virtual function is where the execution of a program written in wxWindows
+starts. The default implementation just enters the main loop and starts
+handling the events until it terminates, either because
+\helpref{ExitMainLoop}{wxappexitmainloop} has been explicitly called or because
+the last frame has been deleted and
+\helpref{GetExitOnFrameDelete}{wxappgetexitonframedelete} flag is \true (this
+is the default).
+
+The return value of this function becomes the exit code of the program, so it
+should return $0$ in case of successful termination.
+
+
+\membersection{wxApp::OnUnhandledException}\label{wxapponunhandledexception}
+
+\func{virtual void}{OnUnhandledException}{\void}
+
+This function is called when an unhandled C++ exception occurs inside
+\helpref{OnRun()}{wxapponrun} (the exceptions which occur during the program
+startup and shutdown might not be caught at all).
+Note that the exception type is lost by now, so if you want to really handle
+the exception you should override \helpref{OnRun()}{wxapponrun} and put a
+try/catch clause around the call to the base class version there.

-\func{bool}{SendIdleEvents}{\void}
-Sends idle events to all top-level windows.

-\func{bool}{SendIdleEvents}{\param{wxWindow*}{ win}}
+\func{bool}{SendIdleEvents}{\param{wxWindow*}{ win}, \param{wxIdleEvent\& }{event}}
Sends idle events to a window and its children.
+Please note that this function is internal to wxWindows and shouldn't be used
+by user code.
+
\wxheading{Remarks}
These functions poll the top-level windows, and their children, for idle event processing.

+
+\constfunc{virtual void}{HandleEvent}{\param{wxEvtHandler}{ *handler}, \param{wxEventFunction}{ func}, \param{wxEvent\& }{event}}
+
+This function simply invokes the given method \arg{func} of the specified
+event handler \arg{handler} with the \arg{event} as parameter. It exists solely
+to allow to catch the C++ exceptions which could be thrown by all event
+handlers in the application in one place: if you want to do this, override this
+function in your wxApp-derived class and add try/catch clause(s) to it.
