// wxmain.cc implements the wxWidgets frame, toolbar, menus, and dialogs.
// When the application starts, the user is given a chance to choose/edit/save
// a configuration. When they decide to start the simulation, functions in
// main.cc are called in a separate thread to initialize and run the Bochs
// simulator.
//
// Most ports to different platforms implement only the VGA window and
// toolbar buttons. The wxWidgets port is the first to implement both
// the VGA display and the configuration interface, so the boundaries
// between them are somewhat blurry. See the extensive comments at
// the top of siminterface for the rationale behind this separation.
//
// The separation between wxmain.cc and wx.cc is as follows:
// - wxmain.cc implements a Bochs configuration interface (CI),
// which is the wxWidgets equivalent of textconfig.cc. wxmain creates
// a frame with several menus and a toolbar, and allows the user to
// choose the machine configuration and start the simulation. Note
// that wxmain.cc does NOT include bochs.h. All interactions
// between the CI and the simulator are through the siminterface
// object.
// - wx.cc implements a VGA display screen using wxWidgets. It is
// is the wxWidgets equivalent of x.cc, win32.cc, macos.cc, etc.
// wx.cc includes bochs.h and has access to all Bochs devices.
// The VGA panel accepts only paint, key, and mouse events. As it
// receives events, it builds BxEvents and places them into a
// thread-safe BxEvent queue. The simulation thread periodically
// processes events from the BxEvent queue (bx_wx_gui_c::handle_events)
// and notifies the appropriate emulated I/O device.
