Straight to the point! How do signals/slots and event/event-listeners compare? Are there any pros and cons? Which one should I consider and why? Thanks in advance! ...
Newb here. I am instantiating the class below from a Silverlight page's code-behind. I am trying to understand why the threads that spin off (the loadoperation and the worker) successfully raise the Selected event on the class when their completed events fire, but the Select event on the method call (in this case the constructer) itsel...
I have started to look at Event-Based Components (EBCs), a programming method currently being explored by Ralf Wesphal in Germany, in particular. This is a really interesting and promising way to architect a software solution, and gets close to the age-old idea of being able to stick software components together like Lego :) A good star...
I am writing a WPF application using C#. I need the application to continue to run for two minutes and then perform some maintenance. The user may not be interacting with it so user driven events are not guaranteed. What is the event I should be monitoring to fulfill this requirement? Here is some pseudo code of what I am considering...

I need help understanding the following. Say I have a display that is 854x480 pixels. Why is it that the MotionEvent.getX and getY methods return floats? As far as I can tell, the pixels on the display are discrete integers, there is no such thing as a half a pixel on the display. ...
There is a page demonstrates how to do it when using Elixir: http://beachcoder.wordpress.com/2007/05/02/adding-event-callbacks-to-sqlalchemyelixir-classes/ But I don't use Elixir, I just use sqlalchemy directly, and define my models as: Base = declarative_base() class User(Base): __tablename__ = "users" ... def send_emai...
Quote from: http://msdn.microsoft.com/en-us/library/aa645739(VS.71).aspx "Invoking an event can only be done from within the class that declared the event." I am puzzled why there is such restriction. Without this limitation I would be able to write a class (one class) which once for good manages sending the events for a given category...

I'm trying to dynamically create context menu items in a Chrome extension; this involves sending a request to the main extension process to modify the menu, and blocking the menu from being displayed until a response is sent. I've been experimenting with different solutions all day, and I have yet to come up with one that works. For ex...
Hi, I have a RichTextBox on my form, and I want to use the default behavior as the RichTextBox does, such as, Ctrl+Z (Undo) or other actions (Ctrl+Y, Ctrl+X, Ctrl+V). If users use the shortcut keys (Ctrl+Z), it's perfect. But what if the users click a ToolStripButton? How can I programmatically simulate a KeyDown Event for RichTextBo...
Hey there! I've been working with JQGrid a lot, and would recommend it to everyone. The one feature I don't really like is the built in multiselect which doesnt use special keys like shift and ctrl, doesnt give you much control and forces checkboxes to be shown. I would like to implement my own multiselect as follows: In onSelectRow- c...
