The target group for this guide to program WML applications are developers creating WML applications for the optiPoint application module.

The guide covers all elements/tags that are part of the WML 1.3 specification. It describes the individual WML elements, their attributes and their interpretation by the WAP browser application as far as it is relevant for the WAP developer.

Of course, this guide does not supersede a WML training manual.

Technical Browser Properties

This chapter specifies the relevant physical properties of the optiPoint application module.

Maximum Data Volume

The following restrictions have to be taken into account when developing WAP pages for the optiPoint application module:

  • The individual cards should not exceed 15 kilobytes (including graphics).
  • A deck should not exceed 80 kilobytes (including graphics).

The optiPoint application module was developed for a wired LAN environment and the HTTP transfer protocol. If the browser is connected via a WAP gateway, WSP can be used instead of HTTP. In this case please consider that some gateways restrict the data volume transferred via WSP. Please also note that WAP gateways usually compile WML pages (i.e. compress them to a binary format). This format considerably reduces the data volume.

Display

If the browser is used, the display is divided into a system bar, a URL entry field, the browser window for the WAP content and the application bar.

Softkeys are not displayed in the default display area but instead shown in the context menus.

The display has a total size of 320 (height) by 240 (width) pixels. If the content is bigger, please take into account that the two scroll bars take a certain part of the available display size. As soon as a vertical scroll bar is shown, the visible width of the browser window is reduced so much that a horizontal scroll bar is also displayed at the bottom of the screen.

If you want to fill the display with a maximum size graphic without triggering the display of scroll bars, rectangles of 230 (width) by 221 (height) pixels or 234 (width) by 192 (height) pixels are available. The difference is due to different threshold values that trigger the generation of scroll bars. In detail, the scroll bar behaviour is as follows: If the maximum height is exceeded, both vertical and horizontal scroll bars are displayed; if only the maximum width is exceeded and the height is smaller than or equals 192 pixels, only a horizontal scroll bar is generated.

The maximum scope for text content is 9 lines (normal font and size). Starting with the 10th line, both a vertical and a horizontal scroll bar are displayed. If a string of characters that cannot be syllabicated exceeds the display width, two things happen: The display is expanded by generating a horizontal scroll bar, and the string of characters is wrapped right in front of the character that exceeds the maximum length.

Using the Browser

The following explains how to use the browser. For detailed information refer to the Operating Manual.

Keyboard and Touchscreen

An alphanumeric keyboard and a touchscreen keypad are available for navigation and data entry. Before you can enter e.g. a URL into the address bar or data into an entry field, the field has to be activated using the touchscreen. Also, task or form elements can only be selected via the context menu, i.e. through the touchscreen.

Certain characters have to be entered via the touchscreen keypad which contains the complete character set. Some special characters (e.g. the * and #) are only available within a submenu of the touchscreen keypad.

Touchscreen Keypad

Starting and Closing the Browser

In the initial state, the optiPoint application module displays the start menu. The user can select the application he wants to use in this menu.
