///////////////////////////////////////////////////////////////// // $Id: wxmain.cc,v 1.109 2004-10-24 20:04:52 vruppert Exp $ ///////////////////////////////////////////////////////////////// // // 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_gui_c::handle_events) // and notifies the appropriate emulated I/O device. // ////////////////////////////////////////////////////////////////////// ////////////////////////////////////////////////////////////////////// // includes ////////////////////////////////////////////////////////////////////// // Define BX_PLUGGABLE in files that can be compiled into plugins.
