event-handling

I am using commanding in my viewmodel to handle events. like for example I am handling a button click event like this: XAML <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <i:InvokeCommandAction Command="{Binding mvvmButtonclick}" /> </i:EventTrigger> </i:Interaction.Triggers> Viewmodel Code public ICommand mvvmButtonclick { get; private set; } Viewmodel Constructor code to wireup the command this.mvvmButtonclick = new ActionCommand(this.ButtonClickedEvent); Actual method in the viewmodel that gets called on button click private void ButtonClickedEvent() { MessageBox.Show("worked!!

What's the key-binding for Control-Shift-Tab? I've tried lots of things and nothing seems to work. I'm already aware of tkinter.ttk.Notebook.enable_traversal. If you know of a handler for tabs being activated, that would suffice, too. Armin The general format for representing an event is: <[event modifier(s)-]...event type [-event detail]>. For key-binding Ctrl+Shift+Tab the format would be: 'Control-Shift-KeyPress-Tab'. In this case the event modifiers would be: Control- Shift-, the event type: Keypress, and the event detail: -Tab The following code (in python 2.7.6) should make it clear:

Given this method to work on a HTML page in a webbrowser: bool semaphoreForDocCompletedEvent; private void button12_Click(object sender, EventArgs e) { checkBox1.Checked = false; //unchecked if the NAvigating event is fired and Checked after DocumentCompleted is fired, only to have a visual reference on the Form HtmlDocument doc = Program.wb.Document; HtmlElement ele = doc.GetElementById("menuTable"); foreach (HtmlElement sub in ele.All) { if (sub.GetAttribute("href").Contains("something")) { ele = sub; break; } } //PHASE 1: clicking on a Web link to navigate to a page that contains other

I have a C# app that subscribes to a topic on our messaging system for value updates. When a new value comes in, I do some processing and then carry on. The problem is, the updates can come faster than the app can process them. What I want to do is to just hold on to the latest value, so I don't want a queue. For example, the source publishes value "1" and my app receives it; while processing, the source publishes the sequence (2, 3, 4, 5) before my app is done processing; my app then processes value "5", with the prior values thrown away. It's kind of hard to post a working code sample since

I want to react, whenever an integer value has changed. So, is there a possibility to write an own eventhandler? I need to get the old value and the new one, because I have to de-reference some events for an object in a list with the index of the old value and reference these events to the listitem with the index of the new value. Something like this (really abstract): value.Changed += new Eventhandler(valuechanged); private void valuechanged(object sender, eventargs e) { list[e.Oldvalue] -= some eventhandler; list[e.newValue] += some eventhanlder; } Thanks. Omar You can do something like this

I have the code included below that allows me to do something the first time a user mouses over an element and then remove the event. It plays nice in the W3C event model browsers but keeps throwing an error in IE6-8. I got the code from another question and believed it would handle IE. Anyone see what I'm doing wrong? <script type="text/javascript"> function setMouseEvent() { //Tel: 01 8279 400 event = addEvent(document.getElementById('contactButton'), 'mouseover', changeText); } function changeText() { alert("worked!"); removeEvent(document.getElementById('contactButton'), 'mouseover',
