]]> ]]> DtEditorSaveContentsToFile library call DtEditorSaveContentsToFile save the contents of a DtEditor widget to a file #include <Dt/Editor.h> DtEditorErrorCode DtEditorSaveContentsToFile Widget widget char *fileName Boolean overwriteIfExists Boolean hardCarriageReturns Boolean markContentsAsSaved The DtEditorSaveContentsToFile function saves the entire contents of the DtEditor widget to a file, optionally replacing soft line feeds (word wraps) with newlines. If the file does not exist and the directory has the correct write permissions, the file is created. If the file exists and the overwriteIfExists argument is set to True, the contents of the file are overwritten. If the file or its directory does not have the correct write permissions, an error is returned. The DtEditor widget tracks whether its contents have changed since they were last saved or retrieved. If the markContentsAsSaved argument is set to False, a copy of the data is saved without affecting whether &cdeman.DtEditorCheckForUnsavedChanges; reports that there are unsaved changes. This is useful if the application needs to save a copy of the contents to a temporary file. The widget argument specifies the DtEditor widget ID. The fileName argument is the pathname of the file relative to the local system. The overwriteIfExists argument, if set to True, causes DtEditorSaveContentsToFile to save the widget contents even though the file specified by the fileName argument exists and has correct write permissions. If this argument is set to False, DtEditorSaveContentsToFile returns DtEDITOR_WRITABLE_FILE. The hardCarriageReturns argument, if set to True, indicates that the widget should replace any soft line feeds (word wraps) with newlines when saving the data. When this argument is set to False, any line wrapped because it reaches the right edge of the window, is saved as one complete line. The markContentsAsSaved argument, when set to True, causes the DtEditor widget to mark that all changes made to date have been saved. When this argument is set to False, the DtEditor widget does not change its status regarding unsaved changes. If an error arises during the save, the status does not change, regardless of the value of the markContentsAsSaved argument. For a complete definition of the DtEditor widget and its associated resources, see &cdeman.DtEditor;. ]]> Upon successful completion, the DtEditorSaveContentsToFile function returns DtEDITOR_NO_ERRORS; otherwise, if it cannot save the data to the file, the function returns one of the following values: DtEDITOR_INVALID_FILENAME No file was specified. DtEDITOR_UNWRITABLE_FILE The application does not have write permission for the file or directory. DtEDITOR_CHAR_SPECIAL_FILE The file is a device-special file. DtEDITOR_BLOCK_MODE_FILE The file is a block-mode device. DtEDITOR_NO_FILE_ACCESS The file cannot be accessed. DtEDITOR_SAVE_FAILED The contents could not be saved for an unspecified reason. DtEDITOR_WRITABLE_FILE The named files exist and the overwriteIfExists argument is set to False. The following code segment saves the contents of a DtEditor widget to the local file, Foo, substituting newlines for soft line feeds. It also indicates that all changes to the contents of the widget have been saved. Widget editor; DtEditorErrorCode status; char *fname = "Foo"; Boolean overwrite = False, hardReturns = True, markContentsAsSaved = True; status = DtEditorSaveContentsToFile(editor, fname, overwrite, hardReturns, markContentsAsSaved); switch(status) { case DtEDITOR_NO_ERRORS: break; case DtEDITOR_WRITABLE_FILE: printf("Save failed. The file already exists.\n"); break; default: printf("Could not save contents.\n"); break; } The application should use &cdeman.DtEditorGetContents; to retrieve the data in a memory buffer, rather than a disk file. &cdeman.Dt.Editor.h;, &cdeman.DtEditor;, &cdeman.DtEditorAppend;, &cdeman.DtEditorAppendFromFile;, &cdeman.DtEditorCheckForUnsavedChanges;, &cdeman.DtEditorGetContents;, &cdeman.DtEditorInsert;, &cdeman.DtEditorInsertFromFile;, &cdeman.DtEditorReplace;, &cdeman.DtEditorReplaceFromFile;, &cdeman.DtEditorSetContentsFromFile;, &cdeman.DtEditorSetContents;.
