Where can I place my code which would execute each draw cycle?
Example: Let's say you want a timer, or a clock.
Then basically you have your Window, and a label.
The label shows the time, but you need to refresh it.
How do you do it?
Another example: You need to re-check if a server got new data, if it does, refresh your data, and then re-draw your Table.
You just call the appropriate method to update the control. For a label that would be setText for a TableViewer you would use update or refresh.
What you must do is execute the UI updates in the user interface thread. If your code is called from a timer or something like that it may not be in the UI thread. In this case use Display.asyncExec to run the update code.
