问题 I am showing custom tab-bar in my application which is showing at centre of the screen. So, Each time one tab should be active and other tabs will be inactive state. According to that, I have implemented logic(bool values) and tried to change images, But, It's not working. My requirement is I have 4 tabs, suppose if user tap on 1st tab, I have to set active image to 1st tab then rest of 3 tabs with inactive images according to those titles (different inactive) images. Its like for all tabs

问题 Good day! I put a picture in a tab bar but it has wrong sizes. Help me solve the problem.I want to fill the entire Item. + (void)setupTabBarAppearance { [[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:30.0f/255.0f green:201.0f/255.0f blue:224.0f/255.0f alpha:1]]; UIImage *image = [[self imageWithColor:[UIColor colorWithRed:255.0f/255.0f green:198.0f/255.0f blue:25.0f/255.0f alpha:1]] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 1, 2) resizingMode:UIImageResizingModeStretch]

问题 I have two ViewControllers inside a tab bar controller. In interface builder, I've applied image insets (5, 5, 5, 5) to the tab bar icons to get their sizes how I want them. Everything looks great when I initially run the simulator, but when I tab to the second ViewController, both tab bar icons automatically resize to the default (0, 0, 0, 0). When I tab back to return to the first ViewController, both icons remain trapped at default size with no insets. Note: My icon images are .pdf files

问题 I created new tab bar project in xcode 4.2 and there is no app delegate xib file. Project has two navigation controller. I can set name of tab bar but couldn't set image.

问题 How would you change the height of the tab bar in a QTabWidget? 回答1: You should create a customized QTabBar and overwrite its tabSizeHint method. Then set that customised QTabBar as the bar of your QTabWidget using the QTabWidget.setTabBar method. I think the following (non tested) code could help you: class TabBar(QTabBar): def tabSizeHint(self, index): width = QTabBar.tabSizeHint(self, index).width() return QSize(width, your_wanted_height) You can find other customization examples here. 来源：

问题 I would like my TabBar to have the ability to show if there are more menu items on either the left or the right. Else the user may not know that more options exist. Something like either arrows to indicate more items or even some sort of beveled effect on the last visible tab item so that it suggests more options are off screen. This is how my TabBar looks like with an arrow showing how the other items are just cut off: Here is the code of the TabBarSkin: public class ScollingTabBarSkin

问题 if I run my app under iOS5 all seems to be fine. But if I try to load a view with a TabBar and some views in it. The screen looks actually like the picture below, so a black tabbar and the first subview of the tabbar which should be onscreen is deallocated. I assume, that the binding between the view and the tabbar does not exist. So I think it has something to do how I link the views with the tabbar. It works like that: NSMutableArray* controllersForHome = [[self.tabBarController

问题 android TabActivity launches the FragmentActivity associated with the first tab added in the sequence before setting tabhost.setCurretnTab(4); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tab_main); try { DataSource.ObjContext = this.getApplicationContext(); DataSource.ObjTabBarActivity = this; DataSource.ObjSharedPreferences = this.getSharedPreferences("com.example", Context.MODE_PRIVATE); if(NetworkStat) { new
