behavior

问题 This question tells me what to do in words, but I can't figure out how to write the code. :) I want to do this: <SomeUIElement> <i:Interaction.Behaviors> <ei:MouseDragElementBehavior ConstrainToParentBounds="True"> <i:Interaction.Triggers> <i:EventTrigger EventName="DragFinished"> <i:InvokeCommandAction Command="{Binding SomeCommand}"/> </i:EventTrigger> </i:Interaction.Triggers> </ei:MouseDragElementBehavior> </i:Interaction.Behaviors> </SomeUIElement> But as the other question outlines, the

问题 We have a requirement for a dexterity content type to have exclude from navigation behaviour but for the exclude_from_nav field's default value to be True . In the behaviour plone.app.dexterity.behaviors.exclfromnav.IExcludeFromNavigation it defaults to False . Obviously I could create my own behaviour that copies IExcludeFromNavigation except for the default value but I was wondering if there was a way to do this based on reusing IExcludeFromNavigation . We have other content types that use

问题 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 回答1: 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

问题 When I have the following: <a name='test'></a> ...and load it in a browser, I can append #test to the URL and the browser will scroll so that the <a> is at the top of the page. However, I would like to change this behavior (using JavaScript if possible) so that using the hash does not scroll the page - I'd like it to simply do nothing. Is there a way to do that without removing the <a> element? Update: I need the browser to still send onhashchange() events but without scrolling to the <a>

问题 I have this strange problem. When debugging, I have sometimetimes code looking like this <?php $var = 15; die($var); die() function works, but outputs nothing However, this one works <?php $var = 15; die($var."<-"); http://sandbox.phpcode.eu/g/81462.php How is it possible? Did I miss something? or is it bug? 回答1: See http://www.php.net/manual/en/function.exit.php (die() is equivalent to exit()) If status is a string, this function prints the status just before exiting. If status is an integer

问题 Firstly, I'd like to preface this with my lack of knowledge about the coordinator layout. I'm merely following tutorials I found online and am curious why my behavior isn't working. Does the child view inside of coordinator layout have to be app bar layout? Or are you able to put any view inside there. Also, when I define the res-auto namespace it doesn't give me the option for layout_behavior. Usually android studio will auto-complete if a function is available and it didn't. Although, if I

问题 I wanted to reverse a list, and I managed to do so, but in the middle of the work I noticed something strange. The following program works as expected but uncommeting line list_reversed[i]=list[len(list)-1-i] and print(list[i]) (commenting the last line of course) leads to a change in list . What am I not seeing? My Python version is 3.3.3. Thank you in advance. list=[1,2,3,4,5,6] list_reversed=list for i in range(0,len(list)): #list_reversed[i]=list[len(list)-1-i] #print(list[i]) print(list
