Ultra Light Client Guide and Reference

UI Engine command options

The UlcUI command starts the user interface engine of ULC with the JIT compiler enabled by default. To run with the JIT compiler disabled, use the UlcUINoJit command.

UlcUI
    [-m]
    [-url URL | -server port_number]
    [-locale ISOlanguage_ISOCountry]
    [-look Look&Feel_class]

The UlcUI program checks if the UI Engine is running and starts it if necessary. The engine can be started with different widget sets or with ULC Monitor, as appropriate.

The UlcUI program expects the directory and file structure in which it is embedded. Always start the program from its location in that tree (UIEngine\bin directory).

Options

-url URL
Starts the UI Engine in production mode; that is, the UI Engine tries to connect to an application server with the given URL. The URL should conform to the following syntax:
ulc://hostName[:portNumber]/[appName]

-m
Starts ULC Monitor, a simple tool for monitoring communication between the UI Engine and connected applications.
ULC Monitor

-autoReconnect
The UI started in client mode will retry to connect to the server for each connection that went down. This will normally start a new context except for ULC Smalltalk applications with enabled Client Reconnect feature. See ULC Client Reconnect Feature for more details.

-doublebuffering
Toggles double buffering. By default, it is on.

-locale
Overrides the default locate of the UI Engine. The format is Language_Country, where language and country are the two-character ISO abbreviations, for example, -locale en_US for English language and the U.S.

-look Look&Feel_class
Specifies the class name for the desired look and feel. Possible values are:

-server port_number
Starts the UI Engine in test mode.
