10 | '\" The definitions below are for supplemental macros used in Tcl/Tk | |
11 | '\" manual entries. | |
12 | '\" | |
13 | '\" .AP type name in/out ?indent? | |
14 | '\" Start paragraph describing an argument to a library procedure. | |
15 | '\" type is type of argument (int, etc.), in/out is either "in", "out", | |
16 | '\" or "in/out" to describe whether procedure reads or modifies arg, | |
17 | '\" and indent is equivalent to second arg of .IP (shouldn't ever be | |
18 | '\" needed; use .AS below instead) | |
19 | '\" | |
20 | '\" .AS ?type? ?name? | |
21 | '\" Give maximum sizes of arguments for setting tab stops. Type and | |
22 | '\" name are examples of largest possible arguments that will be passed | |
23 | '\" to .AP later. If args are omitted, default tab stops are used. | |
24 | '\" | |
25 | '\" .BS | |
26 | '\" Start box enclosure. From here until next .BE, everything will be | |
27 | '\" enclosed in one large box. | |
28 | '\" | |
29 | '\" .BE | |
30 | '\" End of box enclosure. | |

32 | '\" .CS | |
33 | '\" Begin code excerpt. | |
34 | '\" | |
35 | '\" .CE | |
36 | '\" End code excerpt. | |
37 | '\" | |
38 | '\" .VS ?version? ?br? | |
39 | '\" Begin vertical sidebar, for use in marking newly-changed parts | |
40 | '\" of man pages. The first argument is ignored and used for recording | |
41 | '\" the version when the .VS was added, so that the sidebars can be | |
42 | '\" found and removed when they reach a certain age. If another argument | |
43 | '\" is present, then a line break is forced before starting the sidebar. | |
44 | '\" | |
45 | '\" .VE | |
46 | '\" End of vertical sidebar. | |
47 | '\" | |
48 | '\" .DS | |
49 | '\" Begin an indented unfilled display. | |
50 | '\" | |
51 | '\" .DE | |
52 | '\" End of indented unfilled display. | |
53 | '\" | |
54 | '\" .SO | |
55 | '\" Start of list of standard options for a Tk widget. The | |
56 | '\" options follow on successive lines, in four columns separated | |
57 | '\" by tabs. | |
58 | '\" | |
59 | '\" .SE | |
60 | '\" End of list of standard options for a Tk widget. | |
61 | '\" | |
62 | '\" .OP cmdName dbName dbClass | |
63 | '\" Start of description of a specific option. cmdName gives the | |
64 | '\" option's name as specified in the class command, dbName gives | |
65 | '\" the option's name in the option database, and dbClass gives | |
66 | '\" the option's class in the option database. | |
67 | '\" | |
68 | '\" .UL arg1 arg2 | |
69 | '\" Print arg1 underlined, then print arg2 normally. | |

269 | .SH DESCRIPTION | |
270 | .PP | |
271 | \fBTk_ManageGeometry\fR arranges for a particular geometry manager, | |
272 | described by the \fImgrPtr\fR argument, to control the geometry | |
273 | of a particular slave window, given by \fItkwin\fR. | |
274 | If \fItkwin\fR was previously managed by some other geometry manager, | |
275 | the previous manager loses control in favor of the new one. | |
276 | If \fImgrPtr\fR is NULL, geometry management is cancelled for | |
277 | \fItkwin\fR. | |
278 | .PP | |
279 | The structure pointed to by \fImgrPtr\fR contains information about | |
280 | the geometry manager: | |
281 | .CS | |
282 | typedef struct { | |
283 | char *\fIname\fR; | |
284 | Tk_GeomRequestProc *\fIrequestProc\fR; | |
285 | Tk_GeomLostSlaveProc *\fIlostSlaveProc\fR; | |
286 | } Tk_GeomMgr; | |
287 | .CE | |
288 | The \fIname\fR field is the textual name for the geometry manager, | |
289 | such as \fBpack\fR or \fBplace\fR; this value will be returned | |
290 | by the command \fBwinfo manager\fR. | |
291 | .PP | |
292 | \fIrequestProc\fR is a procedure in the geometry manager that | |
293 | will be invoked whenever \fBTk_GeometryRequest\fR is called by the | |
294 | slave to change its desired geometry. | |
295 | \fIrequestProc\fR should have arguments and results that match the | |
296 | type \fBTk_GeomRequestProc\fR: | |
297 | .CS | |
298 | typedef void Tk_GeomRequestProc( | |
299 | ClientData \fIclientData\fR, | |
300 | Tk_Window \fItkwin\fR); | |
301 | .CE | |
302 | The parameters to \fIrequestProc\fR will be identical to the | |
303 | corresponding parameters passed to \fBTk_ManageGeometry\fR. | |
304 | \fIclientData\fR usually points to a data | |
305 | structure containing application-specific information about | |
306 | how to manage \fItkwin\fR's geometry. | |
307 | .PP | |
308 | The \fIlostSlaveProc\fR field of \fImgrPtr\fR points to another | |
309 | procedure in the geometry manager. | |
310 | Tk will invoke \fIlostSlaveProc\fR if some other manager | |
311 | calls \fBTk_ManageGeometry\fR to claim | |
312 | \fItkwin\fR away from the current geometry manager. | |
313 | \fIlostSlaveProc\fR is not invoked if \fBTk_ManageGeometry\fR is | |
314 | called with a NULL value for \fImgrPtr\fR (presumably the current | |
315 | geometry manager has made this call, so it already knows that the | |
316 | window is no longer managed), nor is it called if \fImgrPtr\fR | |
317 | is the same as the window's current geometry manager. | |
318 | \fIlostSlaveProc\fR should have | |
319 | arguments and results that match the following prototype: | |
320 | .CS | |
321 | typedef void Tk_GeomLostSlaveProc( | |
322 | ClientData \fIclientData\fR, | |
323 | Tk_Window \fItkwin\fR); | |
324 | .CE | |
325 | The parameters to \fIlostSlaveProc\fR will be identical to the | |
326 | corresponding parameters passed to \fBTk_ManageGeometry\fR. | |
327 | ||
