| 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. |
| 31 | '\" |
| 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. |

| 340 | .SH DESCRIPTION |
| 341 | .PP |
| 342 | \fBTk_WindowId\fR and the other names listed above are |
| 343 | all macros that return fields from Tk's local data structure |
| 344 | for \fItkwin\fR. None of these macros requires any |
| 345 | interaction with the server; it is safe to assume that |
| 346 | all are fast. |
| 347 | .PP |
| 348 | \fBTk_WindowId\fR returns the X identifier for \fItkwin\fR, |
| 349 | or \fBNULL\fR if no X window has been created for \fItkwin\fR |
| 350 | yet. |
| 351 | .PP |
| 352 | \fBTk_Parent\fR returns Tk's token for the logical parent of |
| 353 | \fItkwin\fR. The parent is the token that was specified when |
| 354 | \fItkwin\fR was created, or NULL for main windows. |
| 355 | .PP |
| 356 | \fBTk_Display\fR returns a pointer to the Xlib display structure |
| 357 | corresponding to \fItkwin\fR. \fBTk_DisplayName\fR returns an |
| 358 | ASCII string identifying \fItkwin\fR's display. \fBTk_ScreenNumber\fR |
| 359 | returns the index of \fItkwin\fR's screen among all the screens |
| 360 | of \fItkwin\fR's display. \fBTk_Screen\fR returns a pointer to |
| 361 | the Xlib structure corresponding to \fItkwin\fR's screen. |
| 362 | .PP |
| 363 | \fBTk_X\fR, \fBTk_Y\fR, \fBTk_Width\fR, and \fBTk_Height\fR |
| 364 | return information about \fItkwin's\fR location within its |
| 365 | parent and its size. The location information refers to the |
| 366 | upper-left pixel in the window, or its border if there is one. |
| 367 | The width and height information refers to the interior size |
| 368 | of the window, not including any border. \fBTk_Changes\fR |
| 369 | returns a pointer to a structure containing all of the above |
| 370 | information plus a few other fields. \fBTk_Attributes\fR |
| 371 | returns a pointer to an XSetWindowAttributes structure describing |
| 372 | all of the attributes of the \fItkwin\fR's window, such as background |
| 373 | pixmap, event mask, and so on (Tk keeps track of all this information |
| 374 | as it is changed by the application). Note: it is essential that |
| 375 | applications use Tk procedures like \fBTk_ResizeWindow\fR instead |
| 376 | of X procedures like \fBXResizeWindow\fR, so that Tk can keep its |
| 377 | data structures up-to-date. |
| 378 | .PP |
| 379 | \fBTk_IsContainer\fR returns a non-zero value if \fItkwin\fR |
| 380 | is a container, and that some other application may be embedding |
| 381 | itself inside \fItkwin\fR. |
| 382 | .PP |
| 383 | \fBTk_IsEmbedded\fR returns a non-zero value if \fItkwin\fR |
| 384 | is is not a free-standing window, but rather is embedded in some |
| 385 | other application. |
| 386 | .PP |
| 387 | \fBTk_IsMapped\fR returns a non-zero value if \fItkwin\fR |
| 388 | is mapped and zero if \fItkwin\fR isn't mapped. |
| 389 | .PP |
| 390 | \fBTk_IsTopLevel\fR returns a non-zero value if \fItkwin\fR |
| 391 | is a top-level window (its X parent is the root window of the |
| 392 | screen) and zero if \fItkwin\fR isn't a top-level window. |
| 393 | .PP |
| 394 | \fBTk_ReqWidth\fR and \fBTk_ReqHeight\fR return information about |
| 395 | the window's requested size. These values correspond to the last |
| 396 | call to \fBTk_GeometryRequest\fR for \fItkwin\fR. |
| 397 | .PP |
| 398 | \fBTk_MinReqWidth\fR and \fBTk_MinReqHeight\fR return information about |
| 399 | the window's minimum requested size. These values correspond to the last |
| 400 | call to \fBTk_SetMinimumRequestSize\fR for \fItkwin\fR. |
| 401 | .PP |
| 402 | \fBTk_InternalBorderLeft\fR, \fBTk_InternalBorderRight\fR, |
| 403 | \fBTk_InternalBorderTop\fR and \fBTk_InternalBorderBottom\fR |
| 404 | return the width of one side of the internal border |
| 405 | that has been requested for \fItkwin\fR, or 0 if no internal border was |
| 406 | requested. The return value is simply the last value passed to |
| 407 | \fBTk_SetInternalBorder\fR or \fBTk_SetInternalBorderEx\fR for \fItkwin\fR. |
| 408 | .PP |
| 409 | \fBTk_Visual\fR, \fBTk_Depth\fR, and \fBTk_Colormap\fR return |
| 410 | information about the visual characteristics of a window. |
| 411 | \fBTk_Visual\fR returns the visual type for |
| 412 | the window, \fBTk_Depth\fR returns the number of bits per pixel, |
| 413 | and \fBTk_Colormap\fR returns the current |
| 414 | colormap for the window. The visual characteristics are |
| 415 | normally set from the defaults for the window's screen, but |
| 416 | they may be overridden by calling \fBTk_SetWindowVisual\fR. |
