New Features in RIM 4.6.0

Setting the Background

There are background classes, located in net.rim.device.api.ui.decor which can be used to create a custom background for a screen or field.

Setting the border

There is a Border class, located in net.rim.device.api.ui.decor which can be used to override the border for any field.

Aligning a field to the beginning or end of text

• A flag (Field:FIELD_LEADING) can be used. Example: if you add the field to a vertical field manager, and the user starts using either English or Chinese characters, the field aligns to the left side of the screen.

RecordStore Size

The size limit of a RecordStore object is now 512 KB.

Messages from Access Control

You can use net.rim.api.applicationcontrol to display a custom message when attempting an operation that the user must permit.

Getting location information for an address

There is a Locator class that will return latitudinal and longitudinal information for a given address. The address is sent to an LBS locator server, and an enumeration with data for the address is returned.

Working with HTML Email Messages

Applications can work with html email messages by performing actions such as retrieving the body of a message.

Listening for sent Messages

You can receive notification when an email, sms, or mms is about to be sent.

Listening for changes to default PIM lists

The PIMListListener3 interface receives notifications when a PIM list changes.

• static double asin(double x): returns the arc sin of x
• static double atan(double x): returns the arc tangent of x
