]]> ]]> DtEditorInsert library call DtEditorInsert insert data into a DtEditor widget #include <Dt/Editor.h> DtEditorErrorCode DtEditorInsert Widget widget DtEditorContentRec *data 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 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 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 &cdeman.DtEditor;. ]]> For a complete definition of DtEditorContentRec, see &cdeman.Dt.Editor.h;. Upon successful completion, the DtEditorInsert function returns DtEDITOR_NO_ERRORS; otherwise, it returns one of the following values: ]]> Upon successful completion, the DtEditorInsert function returns one of the following values: DtEDITOR_NO_ERRORS The data was inserted sucessfully. DtEDITOR_NULLS_REMOVED NULL characters were found and removed from the data. Otherwise, if the DtEditorInsert function cannot insert the data into the DtEditor widget, it returns one of the following values: ]]> DtEDITOR_INVALID_TYPE The Type field is not recognized. 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 insert the data. ]]> The following code segment sets the contents of a DtEditor widget to ``The quick brown fox.''
