ARGUMENTS
Tk_Anchor anchor (in) One of the symbolic constants
TK_ANCHOR_N, TK_ANCHOR_NE,
etc. See Tk_GetAnchorFro-
mObj(3).
Ttk_Box * cavity (in/out) A rectangular region from
which a parcel is allocated.
short border (in) Extra padding (in pixels) to
add uniformly to each side of
a region.
short bottom (in) Extra padding (in pixels) to
add to the bottom of a
region.
Ttk_Box box (in)
Ttk_Box * box_rtn (out) Specifies a rectangular
region.
int height (in) The height in pixels of a
region.
Tcl_Interp * interp (in) Used to store error messages.
int left (in) Extra padding (in pixels) to
add to the left side of a
region.
Tcl_Obj * objPtr (in) String value contains a sym-
bolic name to be converted to
an enumerated value or bit-
mask. Internal rep may be be
modified to cache correspond-
ing value.
Ttk_Padding padding (in)
Ttk_Padding * padding_rtn (out) Extra padding to add on the
inside of a region.
Ttk_Box parcel (in) A rectangular region, allo-
cated from a cavity.
int relief (in) One of the standard Tk relief
options (TK_RELIEF_RAISED,
TK_RELIEF_SUNKEN, etc.). See
Tk_GetReliefFromObj.
short right (in) Extra padding (in pixels) to
add to the right side of a
region.
Ttk_Side side (in) One of TTK_SIDE_LEFT,
TTK_SIDE_TOP, TTK_SIDE_RIGHT,
or TTK_SIDE_BOTTOM.
unsigned sticky (in) A bitmask containing one or
more of the bits TTK_STICK_W
(west, or left), TTK_STICK_E
(east, or right, TTK_STICK_N
(north, or top), and
TTK_STICK_S (south, or bot-
tom). TTK_FILL_X is defined
as a synonym for
(TTK_STICK_W|TTK_STICK_E),
TTK_FILL_Y is a synonym for
(TTK_STICK_N|TTK_STICK_S),
and TTK_FILL_BOTH and
TTK_STICK_ALL are synonyms
for (TTK_FILL_X|TTK_FILL_Y).
See also: grid(n).
Tk_Window tkwin (in) Window whose screen geometry
determines the conversion
between absolute units and
pixels.
short top (in) Extra padding at the top of a
region.
int width (in) The width in pixels of a
region.
int x (in) X coordinate of upper-left
corner of region.
int y (in) Y coordinate of upper-left
corner of region.

BOXES
The Ttk_Box structure represents a rectangular region of a window:
typedef struct {
int x;
int y;
int width;
int height;
} Ttk_Box;
All coordinates are relative to the window.
Ttk_MakeBox is a convenience routine that constructs a Ttk_Box struc-
ture representing a region width pixels wide, height pixels tall, at
the specified x, y coordinates.
Ttk_PadBox returns a new box located inside the specified parcel,
shrunken according to the left, top, right, and bottom margins speci-
fied by padding.
Ttk_ExpandBox is the inverse of Ttk_PadBox: it returns a new box sur-
rounding the specified parcel, expanded according to the left, top,
right, and bottom margins specified by padding.
Ttk_PackBox allocates a parcel width by height pixels wide on the spec-
ified side of the cavity, and shrinks the cavity accordingly.
Ttk_StickBox places a box with the requested width and height inside
the parcel according to the sticky bits.
Ttk_PlaceBox combines Ttk_PackBox and Ttk_StickBox: it allocates a par-
cel on the specified side of the cavity, places a box of the requested
size inside the parcel according to sticky, and shrinks the cavity.
Ttk_AnchorBox places a box with the requested width and height inside
the parcel according to the specified anchor option.
Ttk_BoxContains tests if the specified x, y coordinate lies within the
rectangular region box.
PADDDING
The Ttk_Padding structure is used to represent borders, internal pad-
ding, and external margins:
typedef struct {
short left;
short top;
short right;
short bottom;
} Ttk_Padding;
Ttk_MakePadding is a convenience routine that constructs a Ttk_Padding
structure with the specified left, top, right, and bottom components.
Ttk_UniformPadding constructs a Ttk_Padding structure with all compo-
nents equal to the specified border.
Ttk_AddPadding adds two Ttk_Paddings together and returns a combined
padding containing the sum of the individual padding components.
Ttk_RelievePadding adds an extra 2 pixels of padding to padding accord-
ing to the specified relief. If relief is TK_RELIEF_SUNKEN, adds two
pixels at the top and left so the inner region is shifted down and to
the left. If it is TK_RELIEF_RAISED, adds two pixels at the bottom and
right so the inner region is shifted up and to the right. Otherwise,
adds 1 pixel on all sides. This is typically used in element geometry
procedures to simulate a "pressed-in" look for pushbuttons.
CONVERSION ROUTINES
Ttk_GetPaddingFromObj converts the string in objPtr to a Ttk_Padding
structure. The string representation is a list of up to four length
specifications "left top right bottom". If fewer than four elements
are specified, bottom defaults to top, right defaults to left, and top
defaults to left. See Tk_GetPixelsFromObj(3) for the syntax of length
specifications.
Ttk_GetBorderFromObj is the same as Ttk_GetPaddingFromObj except that
the lengths are specified as integers (i.e., resolution-dependant val-
ues like 3m are not allowed).
Ttk_GetStickyFromObj converts the string in objPtr to a sticky bitmask.
The string contains zero or more of the characters n, s, e, or w.
