问题 How can I theme the list seletor in a ContextMenu? For ListViews I used the way described here: http://brainflush.wordpress.com/2009/03/15/understanding-android-themes-and-styles/ So I assigned the created style to my theme like this: <style name="Theme...." parent="@android:style/Theme.Light"> <item name="android:listViewStyle">@style/ListView</item> </style> 回答1: Try Override context menu colors in Android and see if it helps. It says you can't override the standard context menu selector

Creating a custom slider using Sprite Kit - how do I pass a @selector?

由 ℡╲_俬逩灬. 提交于 2019-12-07 14:21:16
问题 A Sprite Kit game I'm working on uses a custom slider to act as a color picker (the color is picked from the slider track graphic, which is a UIImage containing a gradient).

But what I'm trying to do is: Wait 10 seconds for page to completely load Make sure there are the presence of ten or more span.eN elements (two load on intitial page load and more after) Then start processing the data with beautifulsoup I am struggling with the selenium conditions of either finding the nth element or locating the specific text that only exists in an nth element. I keep

Use colon : or not with selectors

由 大城市里の小女人 提交于 2019-12-07 10:50:35
问题 I was wondering: what's the difference between writing a selector name with no colon @selector(mySelector) , or @selector(mySelector:) with the colon? As in: UIBarButtonItem *addButton = [[UIBarButtonItem alloc]initWith... target:self action:@selector(addAction:)]; I can't find another example without the colon, but I'm quite sure I have already seen some of them. 回答1: The colon is needed after the method's name if and only if the method takes an argument. No function parameters: -(void

Objective-C Calling a selector that the compiler does not believe exists (even though we know it does)

问题 I have this code in a prepareForSegue method // Get destination view UIViewController *viewController = [segue destinationViewController]; //See if it responds to a selector if ([viewController respondsToSelector:@selector(setSomethingOrOther:)]) { //if so call it with some data [viewController setSomethingOrOther:something]; } The code above means I do not have to include a reference to the actual class of the view controller being segue'd to. I can more loosely couple the two view

I've got a webpage that selects a custom-made Raphael radio button immediately after the page loads.
