Blackberry TabScroll and Focus problem - blackberry

I'm a newbe for Blackberry and finding it quite difficult, I'm working on the TabControl example. I have changed the tabs to scroll. Now when i scroll through tabs the focus changes and as soon as the focus shifts to the other tab, the data for that tab appears.
I want to make these tabs clickable only, though they shall scroll but should change only on click.
And also when i use UIApplication.getApplication.pushScreen(someScreen) in the tabs, this someScreen appears out of the tabs, whereas i want to show this screen below the tabs only.
please help

You have to override onFocus(int) to not do anything when focus is moved. (You may or may not have to override touchEvent to handle an actual CLICK event).
You can push a screen into tabs that is not part of the tabs already. If you want something new to appear, try switching managers within the screen instead.

Why tab selection arrows from FMX TabControl disappear at runtime?

I have a TabControl with many tabs. During the design time there is a control artifact like the one the image below where I can scroll the tabs that are not visible, since there is no available space to show them all.
However at runtime it shows up like this:
[
The only way to select the other non visible tabs is using the keyboard arrows when focusing on any of the visible tabs.
The user will not know that there are more hidden tabs with this problem.
The FullSize parameter does not change anything on runtime. Clipchildren, ClipParent, etc does not cause any change.

Work around for -webkit-overflow-scrolling offset bug

The bug is described in detail here https://bugs.webkit.org/show_bug.cgi?id=134596
Relevant part is this:
Without Scrolling you should be able to click any of the radio buttons
Now scroll down the page
Trying to click any of the radio buttons on the left results in an
offset click. One of the radio buttons below your click will receive
the event.
Expected: The radio button I clicked on gets focus
Actual: The click event is offset the amount the iframe was scrolled.
Main difference is im not using an iframe, just a div, but the same problem.
If I remove either overflow:auto (but it wont let me scroll then) or -webkit-overflow-scrolling property the correct clicks happen. It looks like it was fixed in a nightly, but this has to work now and for backwards compatibility. Is there a hack to get this to work? My best idea so far is to just not have that -webkit-overflow-scrolling prop for iOS until it works, but that kinda sucks because momentum scrolling is what makes it feel much more like an app.

Further customise a jQueryMobile custom select menu

Does anyone one know of a workaround/hack ;¬) to further customise jQuery custom select menu - i.e. when we've used
$(document).bind('mobileinit',function(){
$.mobile.selectmenu.prototype.options.nativeMenu = false;
});
to give us a nice list-item overlay in place of the standard listview page on selecting from a select menu.
The jQM docs here http://jquerymobile.com/demos/1.2.1/docs/forms/selects/custom.html - state:
When it has too many options to show on the device's screen, the
framework will automatically create a new "page" populated with a
standard listview for the options. This allows us to use the native
scrolling included on the device for moving through a long list.
I would like to prevent this and always show the custom overlay; obviously the problem is scrolling the options which are out of view. When my project is switched to landscape thus decreasing the screen height it swithces to the 'old school', clunky listview. I should imagine its down to 'absolute' screen metrics since i can see the custom menu overlay will (just about) fit without reverting to the standard view.
The custom view is a much nicer looking interface, and more intuitive from a UI/UX perspective also.
Anyone know of any tricks to keep this behavior??

jQuery Tabbed UI using AJAX - switching between tabs previous view

Let's say I have two tabs tabA and tabB. When I click on tabA the first page of that section appears, call it tabA1. If I click on a link on that page then page tabA1 is replaced with tabA2. If I then click on another tab, say tabB, and then go and click on tabA again I get an image of tabA2 lingering for a bit.
How can I make it so that clicking tabA will always show tabA1 straight away? Is it saving it in the cookies for fast access?
Before switching additionally try setting the content in the tab (or equivalent wrapper) to display : none.
This is happened to me and that's how I fixed it. Although I know it fixes the symptoms and not the exact problem.

Alignment of the TabBarControls in a TabSet

we're using smartGWT for our web application. An the main page is a tabset that shows different tabs. What I want to do is do a button to the tab set with the setTabBarControls method which then is alligned to the left instead to the right. So it would somewhat look like the current Firefox version.
Is there a possibility to change the allignment of the TabBarControls? I couldn't find any.
If you want to create something like the Firefox corner button, just use TabSet.addChild(). That will place the button at the upper left, and you can use setLeft/setTop to move it elsewhere. If you want the control to appear to the left of the tabs, set a layoutStartMargin on the TabBar to leave space for it.
