NAME

       DtEditorGetContents -- retrieve the contents of a DtEditor widget

SYNOPSIS

       #include <Dt/Editor.h>
       DtEditorErrorCode DtEditorGetContents(
       Widget widget,
       DtEditorContentRec *data,
       Boolean hardCarriageReturns,
       Boolean markContentsAsSaved);

DESCRIPTION

       The  DtEditorGetContents  function retrieves the entire contents of a DtEditor widget as a string, wide character string or sized buffer of
       data.  The data is transferred from the DtEditor widget using a DtEditorContentRec, which indicates the	type  of  data	being  transferred
       along with the actual data.  If desired, any soft line feeds (word wraps) can be replaced with <newline>s.

       The  DtEditor  widget  tracks  whether  its contents have changed since they were last saved or retrieved.  Setting the markContentsAsSaved
       argument to True retrieves a copy of the data without affecting whether DtEditorCheckForUnsavedChanges(3) reports that  there  are  unsaved
       changes.  This is useful if the application needs a temporary copy of the contents.

       The widget argument specifies the DtEditor widget ID.

       The data argument is a pointer to a data structure to receive the contents of widget.

       The  hardCarriageReturns  argument, if set to True, indicates that the DtEditor widget should replace any soft line feeds (word wraps) with
       <newline>s when saving the data.  When hardCarriageReturns is set to False, any line wrapped because it reaches the right edge of the  win-
       dow is saved as one complete line.

       The  markContentsAsSaved  argument, if set to True, causes the DtEditor widget to mark that all changes made to date have been saved.  When
       markContentsAsSaved is set to False, the DtEditor widget does not change its status regarding unsaved changes.

       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 DtEditorGetContents function returns DtEDITOR_NO_ERRORS; otherwise, it returns DtEDITOR_INVALID_TYPE if the
       Type field is not recognized.

EXAMPLES

       The following code segment retrieves the contents of a DtEditor widget, marking that all changes to date have been saved.

       Widget		       editor;
       DtEditorContentRec      cr;
       DtEditorErrorCode       status;
       Boolean		       markContentsAsSaved = True;
       cr.type = DtEDITOR_TEXT;
       status = DtEditorGetContents(editor, &cr, False, markContentsAsSaved);
       if (status == DtEDITOR_NO_ERRORS)
	       printf("The contents are:
%s
", cr.value.string);
       else
	       printf("Unable to retrieve contents of the widget
");

APPLICATION USAGE

       To write the data directly to a file, the application should use DtEditorSaveContentsToFile(3).

NAME

       DtEditorSetContentsFromFile -- load data from a file into a DtEditor widget

SYNOPSIS

       #include <Dt/Editor.h>
       DtEditorErrorCode DtEditorSetContentsFromFile(
       Widget widget,
       char *fileName);

DESCRIPTION

       The DtEditorSetContentsFromFile function loads the contents of a file into a DtEditor widget.  Any data currently in the DtEditor widget is
       lost.  After the data is loaded, the insertion cursor is positioned at the first character.

       The widget argument specifies the DtEditor widget ID.

       The fileName argument is the pathname of the file relative to the local system.

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

RETURN VALUE

       Upon successful completion, the DtEditorSetContentsFromFile function returns one of the following values when  it  successfully	loads  the
       data into the DtEditor widget:

       DtEDITOR_NO_ERRORS
		 The file is readable and writable.

       DtEDITOR_READ_ONLY_FILE
		 The file is read only.

       DtEDITOR_NULLS_REMOVED
		 The file contained embedded NULL characters, which were removed.

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

       DtEDITOR_NONEXISTENT_FILE
		 The file does not exist.

       DtEDITOR_DIRECTORY
		 The file is a directory.

       DtEDITOR_CHAR_SPECIAL_FILE
		 The file is a character-special device.

       DtEDITOR_BLOCK_MODE_FILE
		 The file is a block-mode device.

       DtEDITOR_NO_FILE_ACCESS
		 The file cannot be accessed.

       DtEDITOR_INSUFFICIENT_MEMORY
		 Not enough system memory is available to load the file.

       DtEDITOR_UNREADABLE_FILE
		 The file is unreadable for an unspecified reason.

APPLICATION USAGE

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