ARGUMENTS

Tk_Anchor anchor (in) One of the symbolic
constants TK_ANCHOR_N,
TK_ANCHOR_NE, etc. See
Tk_GetAnchorFromObj(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) Specifies a rectangular
region.

Ttk_Box * box_rtn (out) 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
symbolic name to be
converted to an enumerated
value or bitmask. Internal
rep may be be modified to
cache corresponding value.

Ttk_Padding padding (in) Extra padding to add on the
inside of a region.

Ttk_Padding * padding_rtn (out) Padding present in the
inside of a region.

Ttk_Box parcel (in) A rectangular region,
allocated 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
bottom). 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 is a
synonym 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
structure 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
specified by padding.

Ttk_ExpandBox is the inverse of Ttk_PadBox: it returns a new box
surrounding 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
specified 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
parcel 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
padding, 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
components 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
according 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-dependent
values 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.
