Interactive UI Question...

[cbwilliamsva]

Pardon the semi-braindead question.

I've got a very simple UI built - tab display, two tabs. First tab has a table with two columns, second tab has a multi-line text box.

I want to be able to add items to both the table and the text box dynamically from other events that are occurring outside the control of the UI. I've got the table and the text box specified as accessible fields but every time I try to update either I am getting a thread access exception.

What is the proper way to update the SWT user interface from external (non-UI) events?

Thank you in advance,
Chuck

You need to use the Display syncExec(Runnable) or asyncExec(Runnable) method. See...

Eric,

Thank you!

While waiting for a response, I was able to embed my updates into the main control loop via synchronized vectors. It seems to be working well, but I plan on implementing your suggestion.
