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" { #define new xxx_new_xxx #include #include #include "vim.h" #include "globals.h" #include "proto.h" #include "option.h" #undef new } /* extern "C" */ /* ---------------- start of header part ---------------- */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include /* * The macro B_PIXEL_ALIGNMENT shows us which version * of the header files we're using. */ #if defined(B_PIXEL_ALIGNMENT) #define HAVE_R3_OR_LATER 1 #else #define HAVE_R3_OR_LATER 0 #endif class VimApp; class VimFormView; class VimTextAreaView; class VimWindow; extern key_map *keyMap; extern char *keyMapChars; extern int main(int argc, char **argv); #ifndef B_MAX_PORT_COUNT #define B_MAX_PORT_COUNT 100 #endif /* * VimApp seems comparable to the X "vimShell" */ class VimApp: public BApplication { typedef BApplication Inherited; public: VimApp(const char *appsig); ~VimApp(); // callbacks: #if 0 virtual void DispatchMessage(BMessage *m, BHandler *h) { m->PrintToStream(); Inherited::DispatchMessage(m, h); } #endif virtual void ReadyToRun(); virtual void ArgvReceived(int32 argc, char **argv); virtual void RefsReceived(BMessage *m); virtual bool QuitRequested(); static void SendRefs(BMessage *m, bool changedir); private: }; class VimWindow: public BWindow { typedef BWindow Inherited; public: VimWindow(); ~VimWindow(); virtual void DispatchMessage(BMessage *m, BHandler *h); virtual void WindowActivated(bool active); virtual bool QuitRequested(); VimFormView *formView; private: void init(); }; class VimFormView: public BView { typedef BView Inherited; public: VimFormView(BRect frame); ~VimFormView(); // callbacks: virtual void AllAttached(); virtual void FrameResized(float new_width, float new_height); #define MENUBAR_MARGIN 1 float MenuHeight() const { return menuBar ? menuBar->Frame().Height() + MENUBAR_MARGIN: 0; } BMenuBar *MenuBar() const { return menuBar; } private: void init(BRect); BMenuBar *menuBar; VimTextAreaView *textArea; }; class VimTextAreaView: public BView { typedef BView Inherited; public: VimTextAreaView(BRect frame); ~VimTextAreaView(); // callbacks: virtual void Draw(BRect updateRect); virtual void KeyDown(const char *bytes, int32 numBytes); virtual void MouseDown(BPoint point); virtual void MouseUp(BPoint point); virtual void MouseMoved(BPoint point, uint32 transit, const BMessage *message); virtual void MessageReceived(BMessage *m); // own functions: int mchInitFont(char_u *name); void mchDrawString(int row, int col, char_u *s, int len, int flags); void mchClearBlock(int row1, int col1, int row2, int col2); void mchClearAll(); void mchDeleteLines(int row, int num_lines); void mchInsertLines(int row, int num_lines); static void guiSendMouseEvent(int button, int x, int y, int repeated_click, int_u modifiers); static void guiBlankMouse(bool should_hide); static int_u mouseModifiersToVim(int32 beModifiers); int32 mouseDragEventCount; private: void init(BRect); int_u vimMouseButton; int_u vimMouseModifiers; }; class VimScrollBar: public BScrollBar { typedef BScrollBar Inherited; public: VimScrollBar(scrollbar_T *gsb, orientation posture); ~VimScrollBar(); virtual void ValueChanged(float newValue); virtual void MouseUp(BPoint where); void SetValue(float newval); scrollbar_T *getGsb() { return gsb; } int32 scrollEventCount; private: scrollbar_T *gsb; float ignoreValue; }; /* * For caching the fonts that are used; * Vim seems rather sloppy in this regard. */ class VimFont: public BFont { typedef BFont Inherited; public: VimFont(); VimFont(const VimFont *rhs); VimFont(const BFont *rhs); VimFont(const VimFont &rhs); ~VimFont(); VimFont *next; int refcount; char_u *name; private: void init(); }; /* ---------------- end of GUI classes ---------------- */ struct MainArgs { int argc; char **argv; }; /* * These messages are copied through the VDCMP. * Therefore they ought not to have anything fancy. * They must be of POD type (Plain Old Data) * as the C++ standard calls them. */ #define KEY_MSG_BUFSIZ 7 #if KEY_MSG_BUFSIZ < MAX_KEY_CODE_LEN #error Increase KEY_MSG_BUFSIZ!
