Bochs/bochs/gui/wx.cc
Bryce Denney 70d0a6b844 - now that wxmain.h class definition includes a few dialogs from wxdialog.h, 
wxdialog must come first.

/////////////////////////////////////////////////////////////////
//
// wxWindows VGA display for Bochs. wx.cc implements a custom
// wxPanel called a MyPanel, which has methods to display
// text and VGA graphics on the panel. Normally, a MyPanel
// is instantiated within a MyFrame created by wxmain.cc, but
// this is not a requirement.
//
// The separation between wxmain.cc and wx.cc is as follows:
// - wxmain.cc implements a Bochs configuration interface (CI),
// which is the wxWindows equivalent of control.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 wxWindows. It is
// is the wxWindows 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_gui_c::handle_events)
// and notifies the appropriate emulated I/O device.
