The look & feel of standard BlackBerry GUI elements is controlled by current theme. If you need to have different look and feel of a standard TreeField instance then you need to create your own custom field.

I am going to implement Alert feature in my application.
When user taps an alert button my application is about to change all orange (default) colors to red (Navigation bar, switches, Tab bar, Buttons, views and other stuff).
I want to implement it using "css" files also known as stylesheets.
I've found two libraries: Motif and NUI.
The most important problem is to dynamically change theme inside application. Motif can do this but I want to do it more simple.
Also I learned that NUI can change the app theme too but I can't to change it dynamically.
P.S. I am using storyboard and XIB-files. I need to add runtime attribute for object's key-path. This attribute will go to my stylesheet file and apply styles. It's the most simple way I think.
Can I do it simply and without any libraries?
P.S.S. NUI is more simple for me. Maybe you know how to change styles when application runs.
There are ways of making this work, but not very simply. So your options are either to construct your own solution, or use a library.
If you are looking for something that feels easier and more native than NUI or Motif, and which also lets you assign styles and see them rendered live inside your storyboards, take a look at my library for this: https://github.com/daniel-hall/Stylish
Here is a demonstration of changing the "stylesheet" (which can be created either in code, or in an external JSON file) at runtime:
I have been looking around and haven't found a good answer for this.
Instagram uses an image browser/picker like . As you can see above the images from the photo gallery are displayed in a grid below and you can directly choose image from there instead of using the default image picker layout.
The Groupme app also does something similar..
Where images are displayed in a horizontal scrollable list and you can just choose from this.
I have been reading up on the image picker and the documentation says that subclassing is not support.
So my question is:
How do you create something like this?
If this is just a custom view that loads the images stored on the device. How do I access those images?
I just need a starting point and what to specifically look for (custom browser/image picker etc).
Thanks in advance.
You use the ALAssetsLibrary APIs, docs here.
The classes provided by Leaves developed by Tom Brow supports single images for each page of the book with flip effect. In one of our projects we need to show multiple images in a single page along with the flip effect. Has anybody done that with 'Leaves' or is there any other alternative?
We need this images to be added separately so that we can use UIImage selected actions as this images are also required to replaced.This view will also have UITextBox and UILabel.
I know that from iOS 5 on wards UIPageViewController is available which can serve this purpose but for this project we need to support iOS4 also so UIPageViewController can be ruled out.
Try to render two images in a graphics context and then extract the image from the context and draw it in pdfcontext. Hope this might help you.
I have to mix 2 images (from different sprites) and generate a single button out of them.
I tried using the css properties 'border-left-image' and 'border-right-image' in chrome. But it does not work. Tried pre-pending the
id have a look here

this should explain what you need to do and what is doable!
UPDATE
looks like you might be able to accomplish this using multiple background images which is CSS3 based take a look at the link for more information!

I'm scratching a long time itch and have started coding a simple
browser-based image editor in Sproutcore.
70% of my image editing needs consist of cropping pictures. For the
task of selecting which part of the image should remain visible, I
would like to use the interface every image editor uses: the rubber
band (?) selection box.
I'm pretty new to SC and I'm not sure how to go about implementing this. Is there a component available for what I want to do or will I need to write my own?
If I do need to write my own how would I go about doing it? Should I extend SC.ImageView and store the position of the selection box in there?
Thanks.
