<Title>DESCRIPTION</Title>
<Para>The
<Function>DtEditorSetContents</Function> function places a
<SystemItem Class="Constant">NULL</SystemItem>&minus;terminated string, wide character string
or sized buffer into a DtEditor widget.
Any data currently in the DtEditor widget is lost.
The data is transferred to the
DtEditor widget using a
<StructName Role="typedef">DtEditorContentRec</StructName>, which indicates the
type of data being transferred along with the actual data.
After the data is placed into the DtEditor widget, the insertion cursor is
positioned at the first character.
</Para>
<Para>The
<Symbol Role="Variable">widget</Symbol> argument specifies the DtEditor widget ID.
</Para>
<Para>The
