Hi all, Does anybody know how to add an event in the head of the queue for concrete event type? I.e. I have already defined onclick event. A want to add additional call back function, that will be invoked BEFORE already defined callback. Thanks in advance ...
I am writing a Java application using SWT widgets. I would like to update the state of certain widgets upon a certain event happening (for example, updating the data model's state).

I usually do it something like this: private AutoResetEvent _autoResetEvent = new AutoResetEvent(false); private void OnEvent(object sender, EventArgs e){ _autoResetEvent.Set(); } // ... button.Click += OnEvent; try{ _autoResetEvent.WaitOne(); } finally{ b...

I have a multiple menu's on my page which all use the same mouseover and click events, so I decided to get it into a function. However vars seem to always be assigned to the last of the arguments for the hover(function, function) function. $(document).ready( function() { menuMouseOver = function() { for(i=0, u=arguments.length; i<u;...
For another question, I'm running into a misconception that seems to arise here at SO occasionally. Some questioners seem to think that Triggers are to Databases as Events are to OOP. Does anyone have a good analogy to explain why this is a flawed comparison, and the consequences of misapplying it? EDIT: Bill K. has hit it correctly,...
I'm building a test harness for my Delphi 2009 app. Testing the logic is fairly simple. Making sure the forms work properly is proving a bit more complicated. I'd like a way to simulate real user input, to open a form, make it think there's a user typing certain things and clicking in certain places, and make sure it reacts correctly....

To be more specific: I want a unit test to trigger SaveFileDialog's FileOk event in order to test whether my own code (which wraps SFD and does some additional things before and after ShowDialog) is working as intended. Thanks in advance for any help on this. ...

At first I had one window with my custom control. To get it to accept the mouse moved events I simply put in it's awakeFromNib: Code: [[self window] makeFirstResponder:self]; [[self window] setAcceptsMouseMovedEvents:YES]; Now I'm doing something with four of them in the same window, and this doesn't work so pretty anymore. First off,...
I'm trying to override the onError event handler of a web form to allow "A potentially dangerous Request.Form value was detected from the client" type errors to be handled within the form rather than ending up at the application level error handler. I found some sample code like this : protected override void OnError(EventArgs e) { ...
I have been searching for this for some time, but haven't got any explanation. For "onclick" and other events in javascript, the event handler returning false means "prevent default action". However, there is one exception for "onmouseover". For "onmouseover", returning true means "prevent default action". Why is there such a weird exc...
I am in the middle of solving a problem which requires me to do the following in my 64-bit Cocoa application: Spawn a 32-bit Cocoa helper tool (command line tool) from within my application. This helper will open a file (a quicktime movie to be precise) and access information about that file using 32-bit only APIs (Quicktime-C APIs) T...
I've been learning some new features of ASP.NET beyond my current level of comfort, and I'm trying to figure out exactly how custom events can fit in, from a design standpoint. I know how they work, and the observer/subscriber pattern, but it seems that custom events aren't talked about much. It seems like an entire app could be built fr...
I have some handlers to resize a box, I want to move the box according to the handle that was selected.
