customization

问题 Is it possible to create a fully customized alert? I'm doing it with custom sheets now, but I'd like to have the feature that the sheet is blocking (like -[NSAlert runModal] ). I just want to change the background, really, and the text color, of course. 回答1: Warning about the recommended solution: This code causes wasteful and pointless overhead: for (;;) { if ([NSApp runModalSession:session] != NSRunContinuesResponse) break; } This code is copied straight from the Apple documentation page -

问题 Since iOS 5 Apple provided an API to customise the UITabBarItems in the UITabBar object. I am refering specifically to the following selector: setFinishedSelectedImage:withFinishedUnselectedImage: It all works great for regular buttons but I can't seem to customise the "More" button to match the style of the other ones. This is what I am doing: tabBarController.viewControllers = tabBarControllerArray; tabBarController.moreNavigationController.navigationBar.tintColor = [UIColor blackColor];

问题 The suggestions that appear in the default ListView beneath my SearchView contain text that is truncated. I would like the text to be displayed in its entirety (on multiple lines if necessary). I have come up with two possible ways to solve this but, with no examples to be found on the net, I was hoping someone on here may be able to help... Approach #1 / Q1: How can I directly access and modify the appearance of the TextViews that hold the SUGGEST_COLUMN_TEXT_1 and SUGGEST_COLUMN_TEXT_1 text

问题 rand(1,N) but excluding array(a,b,c,..) , is there already a built-in function that I don't know or do I have to implement it myself(how?) ? UPDATE The qualified solution should have gold performance whether the size of the excluded array is big or not. 回答1: No built-in function, but you could do this: function randWithout($from, $to, array $exceptions) { sort($exceptions); // lets us use break; in the foreach reliably $number = rand($from, $to - count($exceptions)); // or mt_rand() foreach (

问题 I want to modify a few tiny details of Django's built-in django.contrib.auth module. Specifically, I want a different form that makes username an email field (and email an alternate email address. (I'd rather not modify auth any more than necessary -- a simple form change seems to be all that's needed.) When I use autodiscover with a customized ModelAdmin for auth I wind up conflicting with auth 's own admin interface and get an "already registered" error. It looks like I have to create my

问题 I need to design this scrollbar for all my scrollpanes : With Java Swing. I am using Netbeans IDE. What is the simplest solution ? Thank you very much. Regards 回答1: You can customize the look of a Swing component by setting a custom UI . In the case of a scroll pane's scroll bar, you do scrollPane.getVerticalScrollBar().setUI(new MyScrollBarUI()); where MyScrollBarUI is derived from javax.swing.plaf.basic.BasicScrollBarUI . To do this for all scroll bars (not only in JScrollPane instances),

问题 I want to display a custom template/item as selected item in ComboBox (this item does not actually exist in the list of items and is updated differently). This does not even needs to be an item, just providing a custom view would work. How can I do this while staying within current ComboBox theme (so no ControlTemplate replacement possible)? As far as I see, all of SelectionBox* properties are not editable and internally ComboBox uses unnamed ContentPresenter. 回答1: I would do it like this:

问题 I would like to have a customized title bar in my Java Swing desktop application. What is the best way to do that? I can use a "Swing-title bar" by using the following code in the constructor for my JFrame: this.setUndecorated(true); this.getRootPane().setWindowDecorationStyle(JRootPane.FRAME); But how do I customize it?
