This is a sample script for rich text serialization/deserialization.
|
||
|
|
|
||
|
|
1. Edit this text using font/color buttons.
|
||
|
|
2. Click save button and save this text (= serialize this as rich text to a file)
|
||
|
|
3. Click clear button and clear this text buffer.
|
||
|
|
4. Click load button and load the file which you save (= deserialize this).
