| '\" The definitions below are for supplemental macros used in Tcl/Tk |
| '\" manual entries. |
| '\" |
| '\" .AP type name in/out ?indent? |
| '\" Start paragraph describing an argument to a library procedure. |
| '\" type is type of argument (int, etc.), in/out is either "in", "out", |
| '\" or "in/out" to describe whether procedure reads or modifies arg, |
| '\" and indent is equivalent to second arg of .IP (shouldn't ever be |
| '\" needed; use .AS below instead) |
| '\" |
| '\" .AS ?type? ?name? |
| '\" Give maximum sizes of arguments for setting tab stops. Type and |
| '\" name are examples of largest possible arguments that will be passed |
| '\" to .AP later. If args are omitted, default tab stops are used. |
| '\" |
| '\" .BS |
| '\" Start box enclosure. From here until next .BE, everything will be |
| '\" enclosed in one large box. |
| '\" |
| '\" .BE |
| '\" End of box enclosure. |
| '\" |
| '\" .CS |
| '\" Begin code excerpt. |
| '\" |
| '\" .CE |
| '\" End code excerpt. |
| '\" |
| '\" .VS ?version? ?br? |
| '\" Begin vertical sidebar, for use in marking newly-changed parts |
| '\" of man pages. The first argument is ignored and used for recording |
| '\" the version when the .VS was added, so that the sidebars can be |
| '\" found and removed when they reach a certain age. If another argument |
| '\" is present, then a line break is forced before starting the sidebar. |
| '\" |
| '\" .VE |
| '\" End of vertical sidebar. |
| '\" |
| '\" .DS |
| '\" Begin an indented unfilled display. |
| '\" |
| '\" .DE |
| '\" End of indented unfilled display. |
| '\" |
| '\" .SO |
| '\" Start of list of standard options for a Tk widget. The |
| '\" options follow on successive lines, in four columns separated |
| '\" by tabs. |
| '\" |
| '\" .SE |
| '\" End of list of standard options for a Tk widget. |
| '\" |
| '\" .OP cmdName dbName dbClass |
| '\" Start of description of a specific option. cmdName gives the |
| '\" option's name as specified in the class command, dbName gives |
| '\" the option's name in the option database, and dbClass gives |
| '\" the option's class in the option database. |
| '\" |
| '\" .UL arg1 arg2 |
| '\" Print arg1 underlined, then print arg2 normally. |

| .SH DESCRIPTION |
| .PP |
| \fBTk_GeometryRequest\fR is called by widget code to indicate its |
| preference for the dimensions of a particular window. The arguments |
| to \fBTk_GeometryRequest\fR are made available to the geometry |
| manager for the window, which then decides on the actual geometry |
| for the window. Although geometry managers generally try to satisfy |
| requests made to \fBTk_GeometryRequest\fR, there is no guarantee that |
| this will always be possible. Widget code should not assume that |
| a geometry request will be satisfied until it receives a |
| \fBConfigureNotify\fR event indicating that the geometry change has |
| occurred. Widget code should never call procedures like |
| \fBTk_ResizeWindow\fR directly. Instead, it should invoke |
| \fBTk_GeometryRequest\fR and leave the final geometry decisions to |
| the geometry manager. |
| .PP |
| If \fItkwin\fR is a top-level window, then the geometry information |
| will be passed to the window manager using the standard ICCCM protocol. |
| .PP |
| \fBTk_SetInternalBorder\fR is called by widget code to indicate that |
| the widget has an internal border. This means that the widget draws |
| a decorative border inside the window instead of using the standard |
| X borders, which are external to the window's area. For example, |
| internal borders are used to draw 3-D effects. \fIWidth\fR |
| specifies the width of the border in pixels. Geometry managers will |
| use this information to avoid placing any children of \fItkwin\fR |
| overlapping the outermost \fIwidth\fR pixels of \fItkwin\fR's area. |
| .PP |
| \fBTk_SetInternalBorderEx\fR works like \fBTk_SetInternalBorder\fR |
| but lets you specify different widths for different sides of the window. |
| .PP |
| \fBTk_SetMinimumRequestSize\fR is called by widget code to indicate |
| that a geometry manager should request at least this size for the |
| widget. This allows a widget to have some control over its size when |
| a propagating geometry manager is used inside it. |
| .PP |
| The information specified in calls to \fBTk_GeometryRequest\fR, |
| \fBTk_SetMinimumRequestSize\fR, \fBTk_SetInternalBorder\fR and |
| \fBTk_SetInternalBorderEx\fR can be retrieved using the macros |
| \fBTk_ReqWidth\fR, \fBTk_ReqHeight\fR, \fBTk_MinReqWidth\fR, |
| \fBTk_MinReqHeight\fR, \fBTk_MinReqWidth\fR, \fBTk_InternalBorderLeft\fR, |
| \fBTk_InternalBorderRight\fR, \fBTk_InternalBorderTop\fR and |
| \fBTk_InternalBorderBottom\fR. |
| See the \fBTk_WindowId\fR manual entry for details. |
