Thanks for reading. I've been stuck on this for quite some time. I'm relatively new and seem to be plateauing in the next step(s) of my application.|
The application attempts to model itself after the Eclipse Task List (Right Click - Opens a new Task (as an editor) with a user input SWT text widget to enter a new task.
When the user enters text I have marked the editor as dirty and have implemented the dirtyStateChanged() method. This in turn provides a prompt when I attempt to close the editor without saving! So far so good.
1. The first problem I am having is how to update the task tree that I originally clicked on to build a new task. I've read a number of articles from Vogella's databinding tutorial to many file:///Users/Jason/Library/Safari/ReadingListArchives/59339612-C88E-42E0-85FB-AF9EC8F0B967/Page.webarchive to IListeners etc. One item I learned is that SWT Tree Widget is not supported in data binding(at least I think). What is the best approach here!?!
2. The second problem I'm having is that I have no concept of where to save that data to retain it after the application is closed. Text file? What is standard practice.
Thanks for any advice, links etc!
