.SH NAME
Tk::TixGrid \- Create and manipulate Tix Grid widgets
.SH SYNOPSIS
.IX Header "SYNOPSIS"
\ \ \ \ \fR\f(CI$tixgrid\fR\fI\fR = \fI\fR\f(CI$parent\fR\fI\fR\->\fBTixGrid\fR?(\fIoptions\fR)?;
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This widget is intended as the basis of "spread sheet" like interfaces.
The widget displays its contents in a two dimensional "grid" of cells.
Each cell may contain one Tix display item, which may be in text,
graphics or other formats. See Tk::DItem for more information
about Tix display items. Because these "items" need not be "windows" large
grids can be handled  without consuming excessive display system resources.
.PP
Individual cells, or groups of cells, can be formatted with a wide range of
attributes, such as its color, relief and border. However because the
widget is intended to handle large grids the mechanisms to achieve these
are lower level, and more callback oriented than for other widgets. The
assumption is that to avoid storing display details of a large number
of cells, the data will be re-computed as needed.
.PP
The port of Tix C code and some of the bindings to perl/Tk is done but still
need further work. In several places the intent of the Tix code is not
yet understood. For example the 'edit' interface is clearly intended
for spread-sheet like cell content editing in an auxillary "entry" widget
or similar, but how that should work is not yet clear.
.PP
The \fBTixGrid\fR method creates a new TixGrid window and returns a
blessed reference of this TixGrid widget.  Additional options,
described below, may be specified on the command line or in the
option database to configure aspects of the \fBTixGrid\fR widget.

If defined, gives a perl/Tk callback to be
executed when the grid cells need to be displayed on the screen.
Its primary purpose is to draw the background of the region
before the cells are rendered on top. This is normally
achieved by calling \fBformatGrid\fR or \fBformatBorder\fR (see below).
However other uses can  be made of this low-level callback. For example it can be used
to "lazily" populate the grid by calling the \fBset\fR method only as cells come
into view.
.Sp
When this callback is called, it is passed with five additional
parameters: \fItype\fR \fIx1\fR \fIy1\fR \fIx2\fR \fIy2\fR.
.Sp
\&\fIx1\fR \fIy1\fR \fIx2\fR \fIy2\fR gives the extent of the region that needs
formatting.
.Sp
\&\fItype\fR gives the logical type of the region in the grid. It may be one of the
following.

.SH "WIDGET METHODS"
.IX Header "WIDGET METHODS"
The \fBTixGrid\fR method creates a TixGrid widget and returns a blessed
reference of this TixGrid widget.  This reference may be used to
invoke various operations on the widget.  It has the following general
form:
.PP
\ \ \ \ \fR\f(CI$tixgrid\fR\fI\fR\->\fBmethod\fR?(\fIarg, arg, ...\fR)?
.PP
\&\fIarg\fRs determine the exact behavior of the method.
.PP
This object supports the \fBconfigure\fR and \fBcget\fR methods
described in Tk::options which can be used to enquire and
modify the options described above.
The widget also inherits all the methods provided by the generic
Tk::Widget class.
.PP
The following additional methods are possible for \fBTixGrid\fR widgets:

.IX Item "$tixgrid->anchorClear"
.PD
Manipulates the \fBanchor cell\fR of the \fBTixGrid\fR widget.
The anchor cell is the end of the selection that is fixed
while the user is dragging out a selection with the mouse.

.IX Item "($bd,$col,$row) = $tixgrid->bdtype(x,y ?,xDelta,yDelta?)"
Determines if the the screen (pixel) position \fIx,y\fR is in a border.
This is useful for changing the mouse cursor when the user points at a
border \- e.g. to indicate that the border can be adjusted
interactively.
.Sp
If in a border returns a list of three elements. First element
is 'xy', 'x' or 'y', second two elements are integers.
(Value of these are not understood, seem to indicate which
column and row of the border the screen position corresponds to?)
.Sp
If not in a border returns an empty list.

The \fBformatBorder\fR and \fBformatBorder\fR methods can only be called by the
\&\fB\-formatcmd\fR callback of the tixGrid widget. They draw the background of
the region described by \fIx1,y1\fR, \fIx2,y2\fR according the the supplied
\&\fIoptions\fR. One call to \fB\-formatcmd\fR callback can make multiple
calls to \fBformatBorder\fR and/or \fBformatBorder\fR for different
sub-regions.
.Sp
\&\fBformatBorder\fR draws the background using Tk relief style,
\&\fBformatGrid\fR also draws grid lines between the cells.
It only makes sense to call one or the other for a particular
sub-region as one will over-write the other.

Selection support methods \- probably buggy.

x1 (y1) has not to be greater than x2 (y2), but only x2 and y2 can be 'max'.
.Sp
BUG: \fIselectionIncludes\fR: has no visible effect (as in Tix). Eh???
.Sp
BUG: \fIselectionClear\fR: only works for 0, 0, max, max (as in Tix). Eh???

When \fIx2, y2\fR are not given they default to \fIx1, y1\fR, respectively.

Creates a new display item at the cell at (\fIx\fR,\fIy\fR). The optional
\&\fB\-itemtype\fR parameter gives the type of the display item.
An additional list of \fIoption-value\fR pairs specify options
of the display item. If a display item already exists at this cell,
the old item will be deleted automatically.

Queries or sets the size of the row or column given by \fIdim\fR and
\&\fIindex\fR. \fIDim\fR may be \fBrow\fR or \fBcolumn\fR.  \fIIndex\fR may be any
non-negative integer that gives the position of a given row (or column).
\&\fIIndex\fR can also be the string \fBdefault\fR; in this case, this method
queries or sets the default size of all rows (or columns).
When no \fIoption-value\fR pair is given, this method returns
a list containing the current size setting of the given row (or column).
When \fIoption-value\fR pairs are given, the corresponding options
of the size setting of the given row are changed. \fI\-option\fR may be
one of the following:
.RS 4
.IP "\fB\-pad0\fR => \fIpixels\fR" 8
.IX Item "-pad0 => pixels"
Specifies the paddings to the left of a column or the top of a row.
.IP "\fB\-pad1\fR => \fIpixels\fR" 8
.IX Item "-pad1 => pixels"
Specifies the paddings to the right of a column or the bottom of a row.
.IP "\fB\-size\fR => \fIval\fR" 8
.IX Item "-size => val"
Specifies the width of a column or the height of a row.
\&\fIVal\fR may be: \fBauto\fR \-\- the width of the column is set
the widest cell in the column; a valid Tk screen distance
unit (see \fBTk_GetPixels\fR); or a real number following by the
word \fBchars\fR (e.g. \fB3.4chars\fR) that sets the width of the
column to the given number of characters.
