| 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. |
