Users cannot interact with the toolbar using

the trackpad.

Best practice: Implementing toolbars

• Use the ToolbarButtonField class and the ToolbarManager class to create toolbars. For more information about

creating toolbars, see the API reference guide for the BlackBerry® Java® SDK and the BlackBerry Java Application UI Quick

Reference Guide.

• Use a toolbar to display frequent actions associated with the application or screen. Use a pop-up menu for actions associated

with the highlighted item. In some cases, such as deleting an item from a list, the same action could appear in the toolbar

and the pop-up menu.

• Do not include the action that occurs when users click or tap the screen.

• Place positive actions or actions associated with the screen, such as New, Send, and Save, at the far left of the toolbar.

• Place more destructive actions at the far right of the toolbar. For example, if the screen displays a list of items that users

can delete, place Delete at the far right of the toolbar.

• If an action appears on the screen (for example, Create a new contact), do not include the action in the toolbar.

• If only infrequent actions are associated with a screen, do not include a toolbar (for example, the Options screen). An

application could have screens with a toolbar and screens without a toolbar.

• If an action involves choice, display the choices in a dialog box. For example, if users can attach a picture, audio file, or video

file to an email message, provide an "Attach" icon in the toolbar and then display a dialog box to allow users to choose the

type of file to attach.

• Include all actions in the toolbar in the full menu for the application.

Guidelines for icons

• Provide a clear, concise tooltip for each icon. Use title case capitalization.
