DtEditorSetContents(3)

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 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 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 <Dt/Editor>.

RETURN VALUE
Upon successful completion, the DtEditorSetContents() function returns one of the following values:

    The data was loaded sucessfully.
    NULL characters were found and removed from the data.

Otherwise, if the DtEditorSetContents() function cannot load the data in the DtEditor widget, it returns one of the following values:

    The Type field is unrecognized.
    The size of the buffer passed in is negative.
    The buffer is NULL.
    Not enough system memory is available to load 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                    *sampleString="The quick brown fox";

    cr.type = DtEDITOR_TEXT;
    cr.value.string = sampleString;
    status = DtEditorSetContents(editor, &cr);
    if (status != DtEDITOR_NO_ERRORS && status != DtEDITOR_NULLS_REMOVED) {
            printf("Unable to set contents of the widget\n");

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