11 | '\" The definitions below are for supplemental macros used in Tcl/Tk | |
12 | '\" manual entries. | |
13 | '\" | |
14 | '\" .AP type name in/out ?indent? | |
15 | '\" Start paragraph describing an argument to a library procedure. | |
16 | '\" type is type of argument (int, etc.), in/out is either "in", "out", | |
17 | '\" or "in/out" to describe whether procedure reads or modifies arg, | |
18 | '\" and indent is equivalent to second arg of .IP (shouldn't ever be | |
19 | '\" needed; use .AS below instead) | |
20 | '\" | |
21 | '\" .AS ?type? ?name? | |
22 | '\" Give maximum sizes of arguments for setting tab stops. Type and | |
23 | '\" name are examples of largest possible arguments that will be passed | |
24 | '\" to .AP later. If args are omitted, default tab stops are used. | |
25 | '\" | |
26 | '\" .BS | |
27 | '\" Start box enclosure. From here until next .BE, everything will be | |
28 | '\" enclosed in one large box. | |
29 | '\" | |
30 | '\" .BE | |
31 | '\" End of box enclosure. | |
32 | '\" | |
33 | '\" .CS | |
34 | '\" Begin code excerpt. | |
35 | '\" | |
36 | '\" .CE | |
37 | '\" End code excerpt. | |
38 | '\" | |
39 | '\" .VS ?version? ?br? | |
40 | '\" Begin vertical sidebar, for use in marking newly-changed parts | |
41 | '\" of man pages. The first argument is ignored and used for recording | |
42 | '\" the version when the .VS was added, so that the sidebars can be | |
43 | '\" found and removed when they reach a certain age. If another argument | |
44 | '\" is present, then a line break is forced before starting the sidebar. | |
45 | '\" | |
46 | '\" .VE | |
47 | '\" End of vertical sidebar. | |
48 | '\" | |
49 | '\" .DS | |
50 | '\" Begin an indented unfilled display. | |
51 | '\" | |
52 | '\" .DE | |
53 | '\" End of indented unfilled display. | |
54 | '\" | |
55 | '\" .SO | |
56 | '\" Start of list of standard options for a Tk widget. The | |
57 | '\" options follow on successive lines, in four columns separated | |
58 | '\" by tabs. | |
59 | '\" | |
60 | '\" .SE | |
61 | '\" End of list of standard options for a Tk widget. | |
62 | '\" | |
63 | '\" .OP cmdName dbName dbClass | |
64 | '\" Start of description of a specific option. cmdName gives the | |
65 | '\" option's name as specified in the class command, dbName gives | |
66 | '\" the option's name in the option database, and dbClass gives | |
67 | '\" the option's class in the option database. | |
68 | '\" | |
69 | '\" .UL arg1 arg2 | |
70 | '\" Print arg1 underlined, then print arg2 normally. | |

286 | .SH DESCRIPTION | |
287 | .PP | |
288 | \fBTk_GeometryRequest\fR is called by widget code to indicate its | |
289 | preference for the dimensions of a particular window. The arguments | |
290 | to \fBTk_GeometryRequest\fR are made available to the geometry | |
291 | manager for the window, which then decides on the actual geometry | |
292 | for the window. Although geometry managers generally try to satisfy | |
293 | requests made to \fBTk_GeometryRequest\fR, there is no guarantee that | |
294 | this will always be possible. Widget code should not assume that | |
295 | a geometry request will be satisfied until it receives a | |
296 | \fBConfigureNotify\fR event indicating that the geometry change has | |
297 | occurred. Widget code should never call procedures like | |
298 | \fBTk_ResizeWindow\fR directly. Instead, it should invoke | |
299 | \fBTk_GeometryRequest\fR and leave the final geometry decisions to | |
300 | the geometry manager. | |
301 | .PP | |
302 | If \fItkwin\fR is a top-level window, then the geometry information | |
303 | will be passed to the window manager using the standard ICCCM protocol. | |
304 | .PP | |
305 | \fBTk_SetInternalBorder\fR is called by widget code to indicate that | |
306 | the widget has an internal border. This means that the widget draws | |
307 | a decorative border inside the window instead of using the standard | |
308 | X borders, which are external to the window's area. For example, | |
309 | internal borders are used to draw 3-D effects. \fIWidth\fR | |
310 | specifies the width of the border in pixels. Geometry managers will | |
311 | use this information to avoid placing any children of \fItkwin\fR | |
312 | overlapping the outermost \fIwidth\fR pixels of \fItkwin\fR's area. | |
313 | .PP | |
314 | \fBTk_SetInternalBorderEx\fR works like \fBTk_SetInternalBorder\fR | |
315 | but lets you specify different widths for different sides of the window. | |
316 | .PP | |
317 | \fBTk_SetMinimumRequestSize\fR is called by widget code to indicate | |
318 | that a geometry manager should request at least this size for the | |
319 | widget. This allows a widget to have some control over its size when | |
320 | a propagating geometry manager is used inside it. | |
321 | .PP | |
322 | The information specified in calls to \fBTk_GeometryRequest\fR, | |
323 | \fBTk_SetMinimumRequestSize\fR, \fBTk_SetInternalBorder\fR and | |
324 | \fBTk_SetInternalBorderEx\fR can be retrieved using the macros | |
325 | \fBTk_ReqWidth\fR, \fBTk_ReqHeight\fR, \fBTk_MinReqWidth\fR, | |
326 | \fBTk_MinReqHeight\fR, \fBTk_MinReqWidth\fR, \fBTk_InternalBorderLeft\fR, | |
327 | \fBTk_InternalBorderRight\fR, \fBTk_InternalBorderTop\fR and | |
328 | \fBTk_InternalBorderBottom\fR. | |
329 | See the \fBTk_WindowId\fR manual entry for details. | |
