SetIText
SetIText Specify the text of an editText item and draw it
#include <Dialogs.h> Dialog Manager
void SetIText(iHandle, textStr );
Handle iHandle ; Handle of editText or statText item
Str255 textStr ; address of a pascal-style string
SetIText sets ( changes) the contents of an editText or statText item in a
dialog and redraws the changed portion of the dialog.
iHandle is handle obtained from a previous call to GetDItem. It is actually
the hText field of a TERec, as used by TextEdit.
textStr is the address of a pascal-style length-prefixed string containing
the desired new text for the item whose handle is iHandle.
Returns: none

Notes: SetIText must be preceded by a call to GetDItem in order to obtain a
valid value for iHandle . See GetIText for an example of usage.
Rather than changing static text with this call, you may find it convenient
to embed ^n text variables in the text and call ParamText to set them up.
Use SelIText to pre-select all or a portion to ease replacement. Use
GetIText to obtain the modified value of the item after calling
