I'm using a storyboard in my iOS 6 app. At the root I have a Tab bar, then I have a number of view controller tabs, enough to get a "More..." item in the bar. Each tab view is embedded in a navigation controller, a very standard setup like the below, except there are more tabs than two, enough to show a "More..." item in the bar:
Yikes, as a newbie I can't post images. Here's a link to an image http://maybelost.com/wp-content/uploads/2011/10/sb22.jpg
The problem is, if you tap "More..." and then you tap one of the items in the overflow list, the view slides in but you get double Nav Bars.
At the top is the bar from the "More..." screen, which is blank except for the back button saying "More...". Just under that is the Navigation controller from the item I picked from the overflow screen, with its title and so on.
The app works normally but obviously this is bad. How can I prevent this?

I know there is a hook for that https://reactnavigation.org/docs/use-scroll-to-top/ . But at the beginning of my project, i created my own bottom tab component instead of using createBottomTabNavigator(). So i have a code like that <BottomNavigator selected={'Explore'} /> at the bottom of five screen. I want to scroll to top when active tab tapped. I can understand that if active tab is tapped but i get that information in BottomNavigator component. So i have no idea how to retrieve that information back to current screen and scroll to top.
In a Codenameone app, I'm trying to develop a carousel with a thumbnail list at the bottom. I've used Tabs control to display files (of diff types like images, video, text, button etc) in carousel style in the center of a form and another Tabs control to display thumbanail images (of the first carousel files) at the bottom of the form. When a user selects a thumbnail image in the bottom carousel, corresponding component should be displayed in the first carousel.
hi.add(BorderLayout.CENTER, mainCarousel);
hi.add(BorderLayout.SOUTH, bottom_tab);
bottom_tab.addSelectionListener((i1, i2) -> {
// bottom_tab.getTabComponentAt(i2).addPointerPressedListener((i) -> {
mainCarousel.getTabComponentAt(i2).setVisible(true);
mainCarousel.getTabComponentAt(i2).repaint();
// });
});
But the component not getting displayed in the central carousel.
Also, I tried to capture the event addPointerPressedListener, but it's not getting fired when I select a thumbnail image.
You can't set tab components to visible/invisible to show/hide them. That won't work. I'm guessing that what you want is a horizontal list for the bottom UI similar to the answer here.
I would suggest using pointer released always. Notice that this will only get delivered to focusable components or the form. To make sure you get the event you can register a pointer release listener on the form.
Still learning ionic. I have a slide menu integrated into the app. The problem that I have is that I want to completely hide ionic nav bar and menu on top for my login view. I tried using ng-show to hide the nav bar based on whether or not current user is authenticated, but all it does is hide the content in the bar, but leaves empty nav bar container on top of the page.
I also tried using ng-if instead of ng-show, which does make the bar disappear completely, but when I need it to become visible again, the code produces an error: Cannot read property 'outerHtml' of null. I guess because the DOM object for the menu is not there anymore.
What is the best way to address this? Am I on the right path or is there a better way to show/hide
In my main view ,there are 4 tab bar items which are always present at the bottom of my screen. Now when I rotate my device to landscape mode and click any of the tabs, then that tab bar view covers only half of the screen. I tried, but did not succeed. I am posting the screen shot of the view:
My tab bar with icons at bottom of the is not showing on all views... like I will go to the following view on button tap... there the tab bar is not showing... this is my onbuttontap function
myAccFunction: function() {
var MyUser=Ext.Viewport.add(Ext.create('Sample.view.Userinfo'));
Ext.Viewport.animateActiveItem(MyUser, this.getSlideLeftTransition());
console.log('UserinfoAction'); },
tab bar is showing when I go directly to the view using icon on the tab bar.. but when I go to the view using button tap tab bar is not showing ..
Viewport is the main view that takes usually full screen. Inside the viewport you normally have a panel with tabbars, navigation/title bar and if you want to present multiple pages there - you use cards layout. But the point would be - not to add these pages directly to the viewport, but rather add them to your main panel.
