tangular region.
int height (in) The height in pix-
els of a region.

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, allocated
from a cavity.
int relief (in) One of the stan-
dard Tk relief
options
(TK_RELIEF_RAISED,

conversion between
absolute units and
pixels.
short top (in) Extra padding at
the top of a
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 contsructs 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 bot-
tom margins specified by padding.
Ttk_ExpandBox is the inverse of Ttk_PadBox: it returns a
new box surrounding the specified parcel, expanded accord-
ing 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 accord-
ing 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 contsructs 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 pad-
ding components.
Ttk_RelievePadding adds an extra 2 pixels of padding to pad-
ding 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 ele-
ment geometry procedures to simulate a "pressed-in" look for
pushbuttons.
CONVERSION ROUTINES
Tk Last change: 8.5 5
Geometry(3) Tk Themed Widget Geometry(3)
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 specifi-
cations.
Ttk_GetBorderFromObj is the same as Ttk_GetPaddingFromObj
except that the lengths are specified as integers (i.e.,
resolution-dependant 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.
