RichMemo/Features

Here're a number of features, that a considered and/or explained.

Load/Save from File

There're no methods to load or save to file from TRichMemo. (There're methods however to load or save to a TStream)

The reason why no file save/load is because accessing a file might require a certain rights. I.e. when file is written, it might be necessary to either create a file or overwrite an existing file. If file is read, it must/should be shared with certain condition.

In every program such rights and access restrictions should/could be different, depending on the task of the program.

Thus, the access file flags should either become a parameters of load/save method, or not even introduced to RichMemo at all. (Leaving a developer with an option, to create TFileStream by themselves with whatever access they find desirable).

There're utility functions introduced LoadRTFFile/SaveRTFFile, but they're not part of the TRichMemo base interface. Also, extending TRichMemo with a class helper, that introduced these method, is an option.

Please, note, if at some point Load/Save File methods are to be added to RichMemo, they must also be implemented via Widgetset interface. Since a native widget might implement load/save file more efficiently (i.e. Cocoa interface).

RichMemo.Lines is TStrings class, which has Load/Save file method. Using these methods you can load/save plain text (without formatting)
