When writing Swing or AWT applications, I’m aware that GUI changes should always be done in the EDT. How does this translate to writing GWT applications?
I’m looking at a scenario when I call the following.
myRequestBuilder.sendRequest(myRequestDate, myRequestCallback)
myRequestCallback modifies the GUI. Having such a construct in Swing, I would make sure that the myRequestCallback invokes the EDT for the GUI changes. Does GWT require me to do something similar as well?
On the web (in browsers), it’s dead easy: everything always executes in the event dispatch thread.
