NAME

DtEditorAppend — append data to a DtEditor widget

SYNOPSIS

#include &<Dt/Editor.h>
DtEditorErrorCode DtEditorAppend(
Widget widget,
DtEditorContentRec *data);

DESCRIPTION

The DtEditorAppend function appends either a NULL-terminated string, wide character string or sized buffer after the last character in a DtEditor widget. The data is transferred to the DtEditor widget using a DtEditorContentRec, which indicates the type of data being transferred along with the actual data. After the data is appended, the insertion cursor is positioned at the new last character.

The widget argument specifies the DtEditor widget ID.

The data argument points to the data structure containing the data to append.

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

For a complete definition of DtEditorContentRec, see Dt/Editor.h - DtEditor(5).

RETURN VALUE

Upon successful completion, the DtEditorAppend function returns one of the following values:

DtEDITOR_NO_ERRORS

The data was appended sucessfully.

DtEDITOR_NULLS_REMOVED

NULL characters were found and removed from the data.

Otherwise, if the DtEditorAppend function cannot append the data into the DtEditor widget, it returns one of the following values:

DtEDITOR_INVALID_TYPE

The type field is unrecognized.

DtEDITOR_ILLEGAL_SIZE

The size of the buffer passed in is negative.

DtEDITOR_NULL_ITEM

The buffer is NULL.

DtEDITOR_INSUFFICIENT_MEMORY

Not enough system memory is available to append the data.

EXAMPLES

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

Widget                  editor;
DtEditorContentRec      cr;
DtEditorErrorCode       status;
char                    *sampleString1="The quick",


                        *secondString2=" brown fox";
cr.type = DtEDITOR_TEXT;
cr.value.string = sampleString1;
status = DtEditorSetContents(editor, &&cr);
if (status != DtEDITOR_NO_ERRORS &&&& status != DtEDITOR_NULLS_REMOVED) {


        printf("Unable to set the contents of the widget0);
} else {


        cr.type = DtEDITOR_TEXT;


        cr.value.string = sampleString2;


        status = DtEditorAppend(editor, &&cr);


        if (status != DtEDITOR_NO_ERRORS)


                printf("Unable to append to the contents of the widget0);
}

APPLICATION USAGE

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