The value of \fIobjPtr\fR -is a standard Tk color name that determines the border colors. -The color indicated by \fIobjPtr\fR will not actually be used in -the border; it indicates the background color for the window -(i.e. a color for flat surfaces). -The illuminated portions of the border will appear brighter than indicated -by \fIobjPtr\fR, and the shadowed portions of the border will appear -darker than \fIobjPtr\fR. -.PP -\fBTk_Alloc3DBorderFromObj\fR returns a token that may be used in later calls -to \fBTk_Draw3DRectangle\fR. If an error occurs in allocating information -for the border (e.g. a bogus color name was given) -then NULL is returned and an error message is left as the result of -interpreter \fIinterp\fR. -If it returns successfully, \fBTk_Alloc3DBorderFromObj\fR caches -information about the return value in \fIobjPtr\fR, which speeds up -future calls to \fBTk_Alloc3DBorderFromObj\fR with the same \fIobjPtr\fR -and \fItkwin\fR. -.PP -\fBTk_Get3DBorder\fR is identical to \fBTk_Alloc3DBorderFromObj\fR except -that the color is specified with a string instead of a value. This -prevents \fBTk_Get3DBorder\fR from caching the return value, so -\fBTk_Get3DBorder\fR is less efficient than \fBTk_Alloc3DBorderFromObj\fR. -.PP -\fBTk_Get3DBorderFromObj\fR returns the token for an existing border, given -the window and color name used to create the border. -\fBTk_Get3DBorderFromObj\fR does not actually create the border; it must -already have been created with a previous call to -\fBTk_Alloc3DBorderFromObj\fR or \fBTk_Get3DBorder\fR. The return -value is cached in \fIobjPtr\fR, which speeds up -future calls to \fBTk_Get3DBorderFromObj\fR with the same \fIobjPtr\fR -and \fItkwin\fR. -.PP -Once a border structure has been created, \fBTk_Draw3DRectangle\fR may be -invoked to draw the border. -The \fItkwin\fR argument specifies the -window for which the border was allocated, and \fIdrawable\fR -specifies a window or pixmap in which the border is to be drawn. -\fIDrawable\fR need not refer to the same window as \fItkwin\fR, but it -must refer to a compatible -pixmap or window: one associated with the same screen and with the -same depth as \fItkwin\fR. -The \fIx\fR, \fIy\fR, \fIwidth\fR, and -\fIheight\fR arguments define the bounding box of the border region -within \fIdrawable\fR (usually \fIx\fR and \fIy\fR are zero and -\fIwidth\fR and \fIheight\fR are the dimensions of the window), and -\fIborderWidth\fR specifies the number of pixels actually -occupied by the border. The \fIrelief\fR argument indicates -which of several three-dimensional effects is desired: -\fBTK_RELIEF_RAISED\fR means that the interior of the rectangle should -appear raised relative to the exterior of the rectangle, and -\fBTK_RELIEF_SUNKEN\fR means that the interior should appear depressed. -\fBTK_RELIEF_GROOVE\fR and \fBTK_RELIEF_RIDGE\fR mean that there should appear to be -a groove or ridge around the exterior of the rectangle. -.PP -\fBTk_Fill3DRectangle\fR is somewhat like \fBTk_Draw3DRectangle\fR except -that it first fills the rectangular area with the background color -(one corresponding -to the color used to create \fIborder\fR). Then it calls -\fBTk_Draw3DRectangle\fR to draw a border just inside the outer edge of -the rectangular area. The argument \fIrelief\fR indicates the desired -effect (\fBTK_RELIEF_FLAT\fR means no border should be drawn; all that -happens is to fill the rectangle with the background color). -.PP -The procedure \fBTk_Draw3DPolygon\fR may be used to draw more complex -shapes with a three-dimensional appearance. The \fIpointPtr\fR and -\fInumPoints\fR arguments define a trajectory, \fIpolyBorderWidth\fR -indicates how wide the border should be (and on which side of the -trajectory to draw it), and \fIleftRelief\fR indicates which side -of the trajectory should appear raised. \fBTk_Draw3DPolygon\fR -draws a border around the given trajectory using the colors from -\fIborder\fR to produce a three-dimensional appearance. If the trajectory is -non-self-intersecting, the appearance will be a raised or sunken -polygon shape. The trajectory may be self-intersecting, although -it's not clear how useful this is. -.PP -\fBTk_Fill3DPolygon\fR is to \fBTk_Draw3DPolygon\fR what -\fBTk_Fill3DRectangle\fR is to \fBTk_Draw3DRectangle\fR: it fills -the polygonal area with the background color from \fIborder\fR, -then calls \fBTk_Draw3DPolygon\fR to draw a border around the -area (unless \fIleftRelief\fR is \fBTK_RELIEF_FLAT\fR; in this case no -border is drawn). -.PP -The procedures \fBTk_3DVerticalBevel\fR and \fBTk_3DHorizontalBevel\fR -provide lower-level drawing primitives that are used by -procedures such as \fBTk_Draw3DRectangle\fR. -These procedures are also useful in their own right for drawing -rectilinear border shapes. -\fBTk_3DVerticalBevel\fR draws a vertical beveled edge, such as the -left or right side of a rectangle, and \fBTk_3DHorizontalBevel\fR -draws a horizontal beveled edge, such as the top or bottom of a -rectangle. -Each procedure takes \fIx\fR, \fIy\fR, \fIwidth\fR, and \fIheight\fR -arguments that describe the rectangular area of the beveled edge -(e.g., \fIwidth\fR is the border width for \fBTk_3DVerticalBevel\fR). -The \fIleftBorder\fR and \fItopBorder\fR arguments indicate the -position of the border relative to the -.QW inside -of the value, and -\fIrelief\fR indicates the relief of the inside of the value relative -to the outside. -\fBTk_3DVerticalBevel\fR just draws a rectangular region. -\fBTk_3DHorizontalBevel\fR draws a trapezoidal region to generate -mitered corners; it should be called after \fBTk_3DVerticalBevel\fR -(otherwise \fBTk_3DVerticalBevel\fR will overwrite the mitering in -the corner). -The \fIleftIn\fR and \fIrightIn\fR arguments to \fBTk_3DHorizontalBevel\fR -describe the mitering at the corners; a value of 1 means that the bottom -edge of the trapezoid will be shorter than the top, 0 means it will -be longer. -For example, to draw a rectangular border the top bevel should be -drawn with 1 for both \fIleftIn\fR and \fIrightIn\fR, and the -bottom bevel should be drawn with 0 for both arguments. -.PP -The procedure \fBTk_SetBackgroundFromBorder\fR will modify the background -pixel and/or pixmap of \fItkwin\fR to produce a result compatible -with \fIborder\fR. For color displays, the resulting background will -just be the color specified when \fIborder\fR was created; for monochrome -displays, the resulting background -will be a light stipple pattern, in order to distinguish the background from -the illuminated portion of the border. -.PP -Given a token for a border, the procedure \fBTk_NameOf3DBorder\fR -will return the color name that was used to create the border. -.PP -The procedure \fBTk_3DBorderColor\fR returns the XColor structure -that will be used for flat surfaces drawn for its \fIborder\fR -argument by procedures like \fBTk_Fill3DRectangle\fR. -The return value corresponds to the color name that was used to -create the border. -The XColor, and its associated pixel value, will remain allocated -as long as \fIborder\fR exists. -.PP -The procedure \fBTk_3DBorderGC\fR returns one of the X graphics contexts -that are used to draw the border. -The argument \fIwhich\fR selects which one of the three possible GC's: -\fBTK_3D_FLAT_GC\fR returns the context used for flat surfaces, -\fBTK_3D_LIGHT_GC\fR returns the context for light shadows, -and \fBTK_3D_DARK_GC\fR returns the context for dark shadows. -.PP -When a border is no longer needed, \fBTk_Free3DBorderFromObj\fR -or \fBTk_Free3DBorder\fR should -be called to release the resources associated with it. -For \fBTk_Free3DBorderFromObj\fR the border to release is specified -with the window and color name used to create the -border; for \fBTk_Free3DBorder\fR the border to release is specified -with the Tk_3DBorder token for the border. -There should be exactly one call to \fBTk_Free3DBorderFromObj\fR or -\fBTk_Free3DBorder\fR for each call to \fBTk_Alloc3DBorderFromObj\fR -or \fBTk_Get3DBorder\fR. -.SH KEYWORDS -3D, background, border, color, depressed, illumination, value, polygon, raised, shadow, three-dimensional effect |
