Mobile Design Patterns -FisheyeList

noreply@blogger.com (Mohamed Shaheen) — Tue, 21 Sep 2010 13:47:00 +0000

Fisheye List - Forum Nokia Wiki

The term fisheye originates from a camera lens, having more detail in the center of the image and less detail on the edges. In a fisheye user interface, the item in focus grows and the non-focus items remain unchanged. A true fisheye list interface would have one item in the middle of the screen, with 2-3 lines of data, a two-line item listing above and below, and all other item having a single line. This thus allows the user to be able to get more content for the item in focus which otherwise might have been missed out with normal view.

Fisheye view can be used in any of the cases where the intent is to display more information to the user for the selected/focused item or portion of the display screen.

A normal list

A fisheye list

Use when

Fish eye can be used when the intention is to show more information for the selected item or the area of the device under focus. The resultant fish eye view/window can be used to show a snapshot of the complete information for the selected item. For example showing the cricket score in 2-3 lines, where you can show the batsmen at the crease, balls faced etc. User can select the list item to explore further, on which if there is still information which would not fit into the fish eye window, you can think about opening a detailed view where the information can be displayed.

Native application development

1. An Intel based Mac., their is a work around to develop on windows machine , this is by installing mac os on virtual machine software such as VMWare .

2. A membership in ADC (Apple Developer Connection) to test your app on your iPhone and distribute it in the app store, costs $99 and apply to the iPhone Developer Program.

3. iPhone SDK.

4. OS X Leopard 10.5

Programmer Skills Prerequisites

Should have at least a fundamental understanding of the following concepts:

• Basic information about Xcode and Interface Builder and their role in developing applications

• How to define new Objective-C classes

• How to manage memory, including how to create and release objects in Objective-C

• The role of delegate objects in managing application behaviors

• The role of the target-action paradigm in managing your user interface

Web Applications (Widget)

1. An Intel based Mac.

2. A membership in ADC (Apple Developer Connection) to test your app on your iPhone and distribute it in the app store, costs $99 and apply to the iPhone Developer Program.

3. iPhone SDK.

4. OS X Leopard 10.5.5

5. Safari 4

6. Safari web development tools

Programmer Skills Prerequisites

• Safari HTML

• AJAX

How to use createNativeQuery method of EntityManager

noreply@blogger.com (Mohamed Shaheen) — Wed, 20 Jan 2010 06:51:00 +0000

here I am using EntityManager method createNativeQuery to execute SQL queries instead of writing Java persistence queries , I find it easier to use SQL queries rather than go and learn another query language syntax , besides that we can select easily select data from any data base object with no need to create object mapping "Entity class" represents it .

in the below class , I am selecting from view ContentView , the data should be returned as list of entity class named category .

the entity class category does have three fields ID,NameEN and NameAR, note the usage of "as" keyword to rename the query output fields to match the category class filed names , the usage of "as" keyword is not optional and absence of it will results SQL error .
