Is it possible to change background of active item in menu? (It's SDK6)
Like in picture:
And how I can get rid of this (last repeat of background):
It seems to me that Menu, as an object, is just a customized popupscreen. Maybe extend popupscreen and draw the focus however you'd like it. Submenus will get trickier.

I need to add a clickable button with a custom image on top of the TMapView, is this possible?
ps: even if I leave the TImage on top of the view, the map overlays it, that is, the button appears quickly until the map rendering overlays it...
edit ps2: There is no code for the example, I simply put a TImage on the Form, either as a child of TMapView, or as a child of TForm, when I test it on android, when opening the app the image appears quickly before the map and then when the map starts to appear it overlays the image...
edit ps3: I don't know if a TImage is the correct way to do this, is this any component to leave on top of the map, that keeps showing up, serving as a button? Just like on Google Maps...
You can't show anything on TMapView because of "z-order" problem. I looked for while to find a solution.
See : Delphi object over TMapView
What do you check to see if the up or down arrow in the listbox vertical scroll bar were clicked.
Looked at dozens of post all over the web and no answer.
What I want to do is if they click up or down then make the next visible item in the list the selected one. Make it highlighted.
thanks all
It looks like the control won't do it natively. You will need to implement it yourself. You can use this post as a guideline:

Note that you will need to handle the WM_VSCROLL message rather than the WM_HSCROLL message as depicted in the code sample.
I created a custom icon, when I assign it to a hard-coded list the custom icon shows. but when I place it to a programmatically added list in a table it doesn't show but instead displays the "plus" icon.
ironically when I try the "delete" built-in icon it properly shows but my custom made icon wont.
these are the scenario:
this is my custom button
$(".ui-icon-customicon").css({'background-image':'url("http://website/mycustomeicon.jpg")','backgroundRepeat':'no-repeat', 'height':'18px', 'width':'18px', 'background-position':'center', 'background-color':'white'});
when I use the above button to a hard-coded list in a Table it properly shows. But when I use it like this...
listItem = document.createElement('li');
listItem.setAttribute("data-icon","customicon");
my icon doesnt show. and instead it displays the "plus" icon. but when I try this....
listItem = document.createElement('li');
listItem.setAttribute("data-icon","delete");
the button changes to the delete (builtin-icon) icon.
Anyone can help me whats the problem? please???
Update
Updating lists
If you add items to a listview, you'll need to call the
refresh() method on it to update the styles and create any nested
lists that are added. For example,
$('ul').listview('refresh');
Custom Icons
To use custom icons, specify a data-icon value that has a unique name
like myapp-email and the button plugin will generate a class by
prefixing ui-icon- to the data-icon value and apply it to the button.
You can then write a CSS rule that targets the ui-icon-myapp-email
class to specify the icon background source. To maintain visual
consistency, create a white icon 18x18 pixels saved as a PNG-8 with
alpha transparency.

I would like to toggle two Fields on a screen, like a simulated tab screen. I tried creating a HorizontalFieldManager and populating it with Field A, then to toggle deleteAll() and add() Field B. Then Repeat to switch them. (Triggered by a button) This works, but in the simulator is locks up after doing this five times. I haven't tried it on a device yet. Is there a better way to to this, or is this pretty much the only way to do something like that?
It sounds like what you want to do is covered by this support article: Create tabbed view screens. I haven't tried it though.
Hello everybody I am trying to create a screen (to see the image click here)
I have set it's backround image also created required list components which are click able by extending Field class. Now my problem is I am not able to set that rounded white color as backround of the list. Please help me. And also because I am new to the blackberry please also tell me the optimized way to create this screen.
i think like this
1) header bar - create manager and embed 2 buttons and 1 label in it
2) bottom bar - create a global class that contains the buttons and define a method that responds to the click event of these buttons
call that class in this main screen
3) for middle part use a list field which is scrollable
