/* vi:set ts=8 sts=4 sw=4: * * VIM - Vi IMproved by Bram Moolenaar * BeBox GUI support Copyright 1998 by Olaf Seibert. * All Rights Reserved. * * Do ":help uganda" in Vim to read copying and usage conditions. * Do ":help credits" in Vim to see a list of people who contributed. * * Based on "GUI support for the Buzzword Enhanced Operating System." * * Ported to R4 by Richard Offer <richard@whitequeen.com> Jul 99 * * Haiku support by Siarzhuk Zharski <imker@gmx.li> Apr-Mai 2009 * */ /* * Structure of the Haiku GUI code: * * There are 3 threads. * 1. The initial thread. In gui_mch_prepare() this gets to run the * BApplication message loop. But before it starts doing that, * it creates thread 2 * 2. The main() thread. This thread is created in gui_mch_prepare() * and its purpose in life is to call main(argc, argv) again. * This thread is doing the bulk of the work. * 3. Sooner or later, a window is opened by the main() thread. This * causes a second message loop to be created: the window thread. * * == alternatively === * * #if RUN_BAPPLICATION_IN_NEW_THREAD... * * 1. The initial thread. In gui_mch_prepare() this gets to spawn * thread 2. After doing that, it returns to main() to do the * bulk of the work, being the main() thread. * 2. Runs the BApplication. * 3. The window thread, just like in the first case. * * This second alternative is cleaner from Vim's viewpoint. However, * the BeBook seems to assume everywhere that the BApplication *must* * run in the initial thread. So perhaps doing otherwise is very wrong. * * However, from a B_SINGLE_LAUNCH viewpoint, the first is better. * If Vim is marked "Single Launch" in its application resources, * and a file is dropped on the Vim icon, and another Vim is already * running, the file is passed on to the earlier Vim. This happens * in BApplication::Run(). So we want Vim to terminate if * BApplication::Run() terminates. (See the BeBook, on BApplication. * However, it seems that the second copy of Vim isn't even started * in this case... which is for the better since I wouldn't know how * to detect this case.) * * Communication between these threads occurs mostly by translating * BMessages that come in and posting an appropriate translation on * the VDCMP (Vim Direct Communication Message Port). Therefore the * actions required for keypresses and window resizes, etc, are mostly * performed in the main() thread. * * A notable exception to this is the Draw() event. The redrawing of * the window contents is performed asynchronously from the window * thread. To make this work correctly, a locking protocol is used when * any thread is accessing the essential variables that are used by * the window thread. * * This locking protocol consists of locking Vim's window. This is both * convenient and necessary. */ extern "C" { #include <assert.h> #include <float.h> #include <syslog.h> #include "vim.h" #include "globals.h" #include "proto.h" #include "version.h" } // extern "C" // ---------------- start of header part ---------------- //#include <Alert.h> #include <Application.h> #include <Beep.h> #include <Bitmap.h> #include <Box.h> #include <Button.h> #include <Clipboard.h> #include <Debug.h> //#include <Directory.h> //#include <Entry.h> #include <File.h> #include <FilePanel.h> #include <FindDirectory.h> //#include <Font.h> #include <IconUtils.h> #include <Input.h> #include <ListView.h> #include <MenuBar.h> #include <MenuItem.h> //#include <MessageQueue.h> //#include <OS.h> #include <Path.h> #include <PictureButton.h> #include <PopUpMenu.h> //#include <Region.h> #include <Resources.h> //#include <Roster.h> #include <Screen.h> #include <ScrollBar.h> #include <ScrollView.h> #include <String.h> #include <StringView.h> //#include <SupportDefs.h> #include <TabView.h> #include <TextControl.h> #include <TextView.h> #include <TranslationUtils.h> #include <TranslatorFormats.h> #include <View.h> #include <Window.h> class VimApp;
