9 '\" The definitions below are for supplemental macros used in Tcl/Tk
12 '\" .AP type name in/out ?indent?
13 '\" Start paragraph describing an argument to a library procedure.
14 '\" type is type of argument (int, etc.), in/out is either "in", "out",
15 '\" or "in/out" to describe whether procedure reads or modifies arg,
16 '\" and indent is equivalent to second arg of .IP (shouldn't ever be
17 '\" needed; use .AS below instead)
20 '\" Give maximum sizes of arguments for setting tab stops. Type and
21 '\" name are examples of largest possible arguments that will be passed
22 '\" to .AP later. If args are omitted, default tab stops are used.
25 '\" Start box enclosure. From here until next .BE, everything will be
26 '\" enclosed in one large box.
29 '\" End of box enclosure.
32 '\" Begin code excerpt.
37 '\" .VS ?version? ?br?
38 '\" Begin vertical sidebar, for use in marking newly-changed parts
39 '\" of man pages. The first argument is ignored and used for recording
40 '\" the version when the .VS was added, so that the sidebars can be
41 '\" found and removed when they reach a certain age. If another argument
42 '\" is present, then a line break is forced before starting the sidebar.
45 '\" End of vertical sidebar.
48 '\" Begin an indented unfilled display.
51 '\" End of indented unfilled display.
54 '\" Start of list of standard options for a Tk widget. The
55 '\" options follow on successive lines, in four columns separated
59 '\" End of list of standard options for a Tk widget.
61 '\" .OP cmdName dbName dbClass
62 '\" Start of description of a specific option. cmdName gives the
63 '\" option's name as specified in the class command, dbName gives
64 '\" the option's name in the option database, and dbClass gives
65 '\" the option's class in the option database.
68 '\" Print arg1 underlined, then print arg2 normally.

255 .AS Tk_ClassProc instanceData
256 .AP Tk_Window tkwin in
257 Token for window to modify.
258 .AP Tk_ClassProcs *procs in
259 Pointer to data structure containing widget specific procedures.
260 The data structure pointed to by \fIprocs\fR must be static:
261 Tk keeps a reference to it as long as the window exists.
262 .AP ClientData instanceData in
263 Arbitrary one-word value to pass to widget callbacks.
268 \fBTk_SetClassProcs\fR is called to register a set of procedures that
269 are used as callbacks in different places.
271 The structure pointed to by \fIprocs\fR contains the following:
273 typedef struct Tk_ClassProcs {
274 unsigned int \fIsize\fR;
275 Tk_ClassWorldChangedProc *\fIworldChangedProc\fR;
276 Tk_ClassCreateProc *\fIcreateProc\fR;
277 Tk_ClassModalProc *\fImodalProc\fR;
280 The \fIsize\fR field is used to simplify future expansion of the
281 structure. It should always be set to (literally) \fBsizeof(Tk_ClassProcs)\fR.
283 \fIworldChangedProc\fR is invoked when the system has altered
284 in some way that requires some reaction from the widget. For example,
285 when a font alias (see the \fBfont\fR manual entry) is reconfigured,
286 widgets configured to use that font alias must update their display
287 accordingly. \fIworldChangedProc\fR should have arguments and results
288 that match the type \fBTk_ClassWorldChangedProc\fR:
290 typedef void Tk_ClassWorldChangedProc(
291 ClientData \fIinstanceData\fR);
293 The \fIinstanceData\fR parameter passed to the \fIworldChangedProc\fR
294 will be identical to the \fIinstanceData\fR paramter passed to
295 \fBTk_SetClassProcs\fR.
297 \fIcreateProc\fR is used to create platform-dependant windows. It is
298 invoked by \fBTk_MakeWindowExist\fR. \fIcreateProc\fR should have
299 arguments and results that match the type \fBTk_ClassCreateProc\fR:
301 typedef Window Tk_ClassCreateProc(
302 Tk_Window \fItkwin\fR,
304 ClientData \fIinstanceData\fR);
306 The \fItkwin\fR and \fIinstanceData\fR parameters will be identical to
307 the \fItkwin\fR and \fIinstanceData\fR parameters passed to
308 \fBTk_SetClassProcs\fR. The \fIparent\fR parameter will be the parent
309 of the window to be created. The \fIcreateProc\fR should return the
312 \fImodalProc\fR is invoked after all bindings on a widget have been
313 triggered in order to handle a modal loop. \fImodalProc\fR should
314 have arguments and results that match the type \fBTk_ClassModalProc\fR:
316 typedef void Tk_ClassModalProc(
317 Tk_Window \fItkwin\fR,
318 XEvent *\fIeventPtr\fR);
320 The \fItkwin\fR parameter to \fImodalProc\fR will be identical to the
321 \fItkwin\fR parameter passed to \fBTk_SetClassProcs\fR. The
322 \fIeventPtr\fR parameter will be a pointer to an XEvent structure
323 describing the event being processed.
