NAME

DtEditorSetContents − place data into a DtEditor widget

SYNOPSIS

#include <Dt/Editor.h>
DtEditorErrorCode DtEditorSetContents(Widget widget,
DtEditorContentRec ∗data);

DESCRIPTION

The DtEditorSetContents() function places a NULL-terminated string, wide character string or sized buffer into a DtEditor widget.  Any data currently in the DtEditor widget is lost.  The data is transfered to the DtEditor widget using a DtEditorContentRec, which indicates the type of data being transfered along with the actual data.  After the data is placed into the DtEditor widget, the insertion cursor is positioned at the first character. 

The widget argument specifies the DtEditor widget ID. 

The data argument is a pointer to a data structure containing the new contents of widget.

For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3). 

For a complete definition of DtEditorContentRec, see <DtEditor>. 

RETURN VALUE

Upon successful completion, the DtEditorSetContents() function returns DtEDITOR_NO_ERRORS; otherwise, if type is unrecognized, the function returns DtEDITOR_INVALID_TYPE.  DtEDITOR_ILLEGAL_SIZE is returned if the size of the buffer passed in is negative. 

EXAMPLES

The following code segment sets the contents of a DtEditor widget to "The quick brown fox."

Widgeteditor;
DtEditorContentReccr;
DtEditorErrorCodestatus;
char∗sampleString="The quick brown fox";
 cr.type = DtEDITOR_TEXT;
cr.value.string = sampleString;
status = DtEditorSetContents ( editor, &cr );
if (status != DtEDITOR_NO_ERRORS)
    printf("Unable to set contents of the widget0);

APPLICATION USAGE

If the data is in a disk file, rather than in memory, the application should use DtEditorSetContentsFromFile(3).
