]]> ]]> DtEditorReplace library call DtEditorReplace replace a portion of the contents of a DtEditor widget #include <Dt/Editor.h> DtEditorErrorCode DtEditorReplace Widget widget XmTextPosition startPos XmTextPosition endPos DtEditorContentRec *data The DtEditorReplace function replaces part of the contents of a DtEditor widget with a string, a wide character string or sized buffer. The data is transferred to the DtEditor widget using a DtEditorContentRec, which indicates the type of data being transferred along with the actual data. All data following the start position and up to, but not including, the end position is replaced. If the start position and the end position are equal, the data is inserted after the end position. The character positions begin at zero and are numbered sequentially from the beginning of the text. After the replacement, the insertion cursor is positioned after the last character inserted. The widget argument specifies the DtEditor widget ID. The startPos argument specifies the starting character position of the portion to replace. The replacement begins at this character. The endPos argument specifies the ending character position of the portion to replace. The replacement ends before this character. The data argument is a pointer to the 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 DtEditorReplace function returns DtEDITOR_NO_ERRORS; otherwise, if it cannot replace the string, the function returns one of the following values: ]]> Upon successful completion, the DtEditorReplace function returns one of the following values: DtEDITOR_NO_ERRORS The data was replaced sucessfully. DtEDITOR_NULLS_REMOVED NULL characters were found and removed from the data. Otherwise, if the DtEditorReplace function cannot replace the data in the DtEditor widget, it returns one of the following values: ]]> DtEDITOR_INVALID_TYPE The Type field is not recognized. DtEDITOR_INVALID_RANGE The startPos argument is greater than the endPos argument. DtEDITOR_ILLEGAL_SIZE The size of the buffer passed in is negative. DtEDITOR_NULL_ITEM The data buffer is NULL. DtEDITOR_INSUFFICIENT_MEMORY Not enough system memory is available to replace the data. ]]> The following code segment modifies the contents of a DtEditor widget to ``The quick fox.''
