This section explains some features of dcBrowser that may not be standard
for HTML applications.
When you enable the links feature on the dcBrowser Device Mapping
Configuration page, you can use the stylus and touch screen when viewing
web pages on a device with a touch screen. For help opening the dcBrowser
Device Mapping Configuration page, see the dcBrowser online help.
When you enable the links feature, dcBrowser assigns the Enter key (EN>),
and then it assigns function keys to anchor tags and input type="submit"
tags. Up to ten function keys are assigned to links in the order they are
encountered in the HTML file. Only http links are supported, and you can
control the function that is assigned.
For example,
<INPUT TYPE="submit" VALUE="Help" NAME="HlpScrn1">
In a normal web browser, a button that contains the name "Help" appears.
When the user clicks this button, the form-processing sequence begins and
the application tells the web server HlpScrn1=Help. If you enable the links
feature, the device displays a function key, a greater-than sign, and the value
that is the name of the button in a normal web browser:
F1>Help
When you press F1, the form-processing sequence begins, and the
application tells the web server that HlpScrn1=Help (just as it would if the
anchor was selected with a mouse in a standard browser).
If you disable the links feature, the value is ignored, and the name is
whichever function key was pressed. The application tells the web server
that Action=function key. That is, if you press F1, the application tells the
web server that Action=F1. The application handles function key responses.
If you disable the links feature, you cannot use the stylus and touch screen
while viewing web pages.
dcBrowser supports using auto-transmit fields, and it supports using the
scan-ahead and type-ahead features to enter data. Although not standard
for HTML applications, these features are most useful for repetitive screens
with long refresh rates, such as a timecard system in which people scan a
badge as they walk through a door.
