See tkGrab.c for details * TK_CHECKED_IC: 1 means we've already tried to get an input * context for this window; if the ic field is * NULL it means that there isn't a context for * the field. * TK_DONT_DESTROY_WINDOW: 1 means that Tk_DestroyWindow should not * invoke XDestroyWindow to destroy this widget's * X window. The flag is set when the window has * already been destroyed elsewhere (e.g. by * another application) or when it will be * destroyed later (e.g. by destroying its parent) * TK_WM_COLORMAP_WINDOW: 1 means that this window has at some time * appeared in the WM_COLORMAP_WINDOWS property * for its toplevel, so we have to remove it from * that property if the window is deleted and the * toplevel isn't. * TK_EMBEDDED: 1 means that this window (which must be a * toplevel) is not a free-standing window but * rather is embedded in some other application. * TK_CONTAINER: 1 means that this window is a container, and * that some other application (either in this * process or elsewhere) may be embedding itself * inside the window. * TK_BOTH_HALVES: 1 means that this window is used for * application embedding (either as container or * embedded application), and both the containing * and embedded halves are associated with * windows in this particular process. * TK_DEFER_MODAL: 1 means that this window has deferred a modal * loop until all of the bindings for the current * event have been invoked. * TK_WRAPPER: 1 means that this window is the extra wrapper * window created around a toplevel to hold the * menubar under Unix. See tkUnixWm.c for more * information. * TK_REPARENTED: 1 means that this window has been reparented * so that as far as the window system is * concerned it isn't a child of its Tk parent. * Initially this is used only for special Unix * menubar windows. * TK_ANONYMOUS_WINDOW: 1 means that this window has no name, and is * thus not accessible from Tk. * TK_HAS_WRAPPER 1 means that this window has a wrapper window * TK_WIN_MANAGED 1 means that this window is a child of the root * window, and is managed by the window manager. * TK_TOP_HIERARCHY 1 means this window is at the top of a physical * window hierarchy within this process, i.e. the * window's parent either doesn't exist or is not * owned by this Tk application. * TK_PROP_PROPCHANGE 1 means that PropertyNotify events in the * window's children should propagate up to this * window. * TK_WM_MANAGEABLE 1 marks a window as capable of being converted * into a toplevel using [wm manage]. */ #define TK_MAPPED 1 #define TK_TOP_LEVEL 2 #define TK_ALREADY_DEAD 4 #define TK_NEED_CONFIG_NOTIFY 8 #define TK_GRAB_FLAG 0x10 #define TK_CHECKED_IC 0x20 #define TK_DONT_DESTROY_WINDOW 0x40 #define TK_WM_COLORMAP_WINDOW 0x80 #define TK_EMBEDDED 0x100 #define TK_CONTAINER 0x200 #define TK_BOTH_HALVES 0x400 #define TK_DEFER_MODAL 0x800 #define TK_WRAPPER 0x1000 #define TK_REPARENTED 0x2000 #define TK_ANONYMOUS_WINDOW 0x4000 #define TK_HAS_WRAPPER 0x8000 #define TK_WIN_MANAGED 0x10000 #define TK_TOP_HIERARCHY 0x20000 #define TK_PROP_PROPCHANGE 0x40000 #define TK_WM_MANAGEABLE 0x80000  /* *-------------------------------------------------------------- * * Procedure prototypes and structures used for defining new canvas items: * *-------------------------------------------------------------- */ typedef enum { TK_STATE_NULL = -1, TK_STATE_ACTIVE, TK_STATE_DISABLED, TK_STATE_NORMAL, TK_STATE_HIDDEN } Tk_State; typedef struct Tk_SmoothMethod { char *name; int (*coordProc) _ANSI_ARGS_((Tk_Canvas canvas, double *pointPtr, int numPoints, int numSteps, XPoint xPoints[], double dblPoints[])); void (*postscriptProc) _ANSI_ARGS_((Tcl_Interp *interp, Tk_Canvas canvas, double *coordPtr, int numPoints, int numSteps)); } Tk_SmoothMethod; /* * For each item in a canvas widget there exists one record with the following * structure.
