.de Lt \" Form Section on Layout semantics
The \\$1 widget uses two different sets of layout semantics. One is
used when initially laying out the children. The other is used when
the \\$1 is resized.
.LP
The first layout method uses the \fBfromVert\fP and \fPfromHoriz\fP
.IN "fromVert" "
.IN "fromHoriz" ""
resources to place the children of the \\$1. A single pass is made
through the \\$1 widget's children in the order that they were created.
Each child is then placed in the \\$1 widget below or to the right of
the widget specified by the \fBfromVert\fP and \fBfromHoriz\fP resources.
The distance the new child is placed from its left or upper neighbor is
determined by the \fBhorizDistance\fP and \fBvertDistance\fP resources.
.IN "horizDistance" ""
.IN "vertDistance" ""
.IN "conversions" "Widget"
This implies some things about how the order of creation affects the
possible placement of the children. The Form widget registers a
string to widget converter which does not postpone conversion and
does not cache conversion results.
.LP
The second layout method is used when the \\$1 is resized. It does not
matter what causes this resize, and it is possible for a resize to
happen before the widget becomes visible (due to constraints imposed by
the parent of the \\$1). This layout method uses the \fBbottom\fP,
\fBtop\fP, \fBleft\fP, and \fBright\fP resources. These resources are
used to determine what will happen to each edge of the child when the
\\$1 is resized. If a value of \fBXawChain\fP\fI<something>\fP is
.IN "XawChain" ""
specified, the the edge of the child will remain a fixed distance from
the \fIchain\fP edge of the \\$1. For example if \fBXawChainLeft\fP is
specified for the \fBright\fP resource of a child then the right edge of
that child will remain a fixed distance from the left edge of the \\$1
widget. If a value of \fBXawRubber\fP is specified, that edge will grow
.IN "XawRubber" ""
by the same percentage that the \\$1 grew. For instance if the \\$1
grows by 50% the left edge of the child (if specified as \fBXawRubber\fP
will be 50% farther from the left edge of the \\$1). One must be very
careful when specifying these resources, for when they are specified
incorrectly children may overlap or completely occlude other children
when the \\$1 widget is resized.

displayed. This string is normally copied by the text widget into
internal memory, but may be used in place by setting the
\fBuseStringInPlace\fP resource. As of X11R4 this is a settable resource.

When the \fBstring\fP resource is queried, using \fBXtGetValues\fP, and
\fBuseStringInPlace\fP is false, the value returned is valid until
the next time the \fBstring\fP resource is queried, or until the application
writer calls \fBXawAsciiSourceFreeString\fP. If \fBuseStringInPlace\fP is
true, a pointer to the actual string is returned. See also section 5.6.

This resource may be either \fBXawAsciiString\fP or
\fBXawAsciiFile\fP. The value of this resource determines whether the
\fBstring\fP resource contains the name of a file to be opened or a buffer to
be displayed by the text widget. A converter has been registered for
this resource and accepts the values \fBstring\fP and \fBfile\fP.

Setting this resource to \fBTrue\fP will disable the memory management
provided by the Text widget, updating the \fBstring\fP resource in
place. Using the string in place can
be much more efficient for text widgets that display static data, or
where the programmer wishes to impose strict constraints on the
contents of the \fBstring\fP. When using the string in place be sure that:
the length of the string is specified by setting the \fBlength\fP resource,
the \fBtype\fP of the Text widget is \fBXawAsciiString\fP, and that
the \fBstring\fP exists for the lifetime of the text widget, or until it has
been reset. \fINote: Since the MultiSrc and AsciiSrc have different data
formats, use of this resource forces application code to be cognisant as to
which of the two is being used. Application programming is simplified when
use of this resource is avoided.\fP
