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. +.SH KEYWORDS +geometry, request |
