NAME

DtEditorInsert − insert data to a DtEditor widget

SYNOPSIS

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

DESCRIPTION

The DtEditorInsert() function inserts either a string, wide character string or sized buffer at the insertion cursor position in a DtEditor widget. 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 appended, the insertion cursor is positioned after the last character inserted. 

The widget argument specifies the DtEditor widget ID. 

The data argument is a pointer to a data structure containing the data to insert. 

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 DtEditorInsert() function returns DtEDITOR_NO_ERRORS; otherwise, if type is not recognized, 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∗sampleString1="The brown fox",
∗sampleString2=" quick";
 cr.type = DtEDITOR_TEXT;
cr.value.string = sampleString1;
status = DtEditorSetContents ( editor, &cr );
if (status != DtEDITOR_NO_ERRORS) {
  printf("Unable to set contents of the widget\n");
}
else {
  /∗
   ∗ Move the insertion cursor so it is after the
   ∗ letter ’e’ in "The".
   ∗/
   DtEditorSetInsertionCursorPosition( editor, 2);
   cr.type = DtEDITOR_TEXT;
  cr.data.string = sampleString2;
  status = DtEditorInsert ( editor, &cr );
  if (status != DtEDITOR_NO_ERRORS)
    printf("Unable to insert into the contents of the widget\n");
}

APPLICATION USAGE

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