behavior

So I stumbled upon a problem while learning MVVM. I had a TreeView that contained TextBlocks which I wanted to perform an action on when I double clicked any of the TextBlocks in the TreeView. I started to learn about Behaviors, and I have a great example of how a behavior is implemented but the example does not connect the Behavior to a ViewModel at all. So in other words, if I double click on the TextBlock, I have the Behavior class that catches it but I don't have any ViewModel to perform any actions. Could someone take a moment and explain how these tie in? I was reviewing this article:

I have spent a lot of time trying jquery/javscript "fix" to get this worked. Since the last update of chrome mobile for IOS, the address bar of the browser behaves differently. I'm sure you guys are aware of what I'm talking about: You scroll down your page, the bar hides up, but once you scroll up, it appears. Yes, it is a good user experience, I can tell. The problem is that I do have fixed element on top of my web app (header), and every time I scroll up, the address bar goes over my fixed element. I've lookup other web apps (twitter, gmail), and they seems to have found a way to avoid this

My listener is part of a behavior, that should remove all is_published checks in the where clause of any called select query. Adding a part to a clause is really easy, but how to remove one. There are some functions like Doctrine_Query->removeDqlQueryPart('where') , but that removes the complete where clause, while I only need the 'is_published = ?' part to be removed. However I could handle this manually somehow, with regex or something. But the tricky part is, how to remove the parameter represented by the '?' from the corresponding parameters array (retrievable by Doctrine_Query-

Yii2 framework. The idea to create common behavior for common model: before Validate trims all fields in model. if it's array trim all values in array. I'm wondered why in Yii2 core doesn't exist such possibility. Or I'm wrong. Am I? What problems could I face if I trim all fields? You can create a behavior and attach it at your models. 1) Create the behavior TrimBehavior in common/components . <?php namespace common\components; use yii\db\ActiveRecord; use yii\base\Behavior; class TrimBehavior extends Behavior { public function events() { return [ ActiveRecord::EVENT_BEFORE_VALIDATE =>

I just switched from eclipse to Notepad++ and I modified some behaviour of notepad, but there is still one not resolved : When I double-click on a variable I expect my editor to catch the entire variable. Notepad excludes automatically the php prefix "$", that is not efficient. Is there a way I can change the behaviour ? Thank you I understand your problem, but unfortunately it is not possible with Notepad++ to setup this behaviour. What you can do is click between the dollar sign and the variable name. Then you will grab the whole variable as long as there is no special character before the
