the page, which contains a rudimentary display of how the applet may appear when it is
used. The applet window can be resized to the required size by dragging the edges of the
window. The applet properties are displayed in the page designer when the applet is
selected. Some applets have their own specific properties but there are a number of
properties common across all applets:
Font – creates or selects the font used by the applet for displaying text. See
Fonts
for
more information.
Text colour – selects the colour of most text displayed by the applet.
Background colour – selects the colour of the background when the transparent
option is not selected.
Transparent – selects between transparent and opaque backgrounds. Note that
controls cannot overlap the applet window if an opaque background is used.
Device – selects the device to be controlled by the applet. Interaction with the
equipment occurs via a serial port on the AX-R4 router, which means that a device
must be configured and selected in the applet (see
Devices
).
Applets that apply to radio stations have a list of frequencies with their station names and
icons, which are displayed in the applet when the appropriate frequencies are selected. (Note
that the frequencies must be written exactly as displayed by the applet, e.g. “FM 89.40” and
not “FM89.4”.) Depending on the applet, other properties may exist for further text colours,
sound effects, etc.
Applet specific button classes also exist. This allows buttons to control an applet and to
display feedback based on data known to the applet. The applet specific classes are found in
the button class selection under “Applets”. The selected class will only work if the
corresponding applet is used in the same page.
Some applets will use volume controls if they are assigned to the applet. To assign a volume
control to an applet, it must be placed completely inside of the applet's window in the page
designer. The following applets use volume controls:
Integra Receiver applet, for controlling the receiver's volume setting.
Vantage, for controlling load levels.
Restrictions:
A page can contain a maximum of two applets on the KPC 2.8.
Each type of applet should only be used once on a page, otherwise the applet
corresponding to any button classes will be ambiguous. (However multiple Integra
Receivers for different zones is not a problem as each zone is a different type of
applet.)
Fonts
Applets are able to display high quality anti-aliased text using fonts. Each font contains data
for displaying characters in one particular size and style only. For example, “Arial, 12pt” and
“Arial, 16pt” are two separate fonts. Unicode is supported for devices such as the iPort and
currently extended Latin, Greek and Cyrillic character subsets can be optionally included into
the font. Other subsets may be supported in the future should the need arise.
Note that the font colour and “Script” options are not relevant.
