fgl_getproperty()

This function takes three arguments and is used as below:

fgl_getproperty(["gui/server"], type.name, value)

In the above syntax,

• gui refers to the sub-system that the property belongs to. This optional parameter defaults to "gui", so it can be omitted. The type is the element of the subsystem that the property affects; the name is the actual name of the property.
• server refers to the application server properties

GUI properties are script-like properties that can be used to determine the overall look and functionality of a 4GL program. Unlike script options, the GUI properties are dynamic and so can be used to alter a program’s appearance during its execution, allowing for greater customization.

Other kinds of properties that you can get are:

• read registry settings
• environment variables
• system parameters, IP address, system name, host name
• script options currently set
• any arbitrary user properties

property type	property name	example
system.registry	registry key to be read	CALL fgl_getproperty("system.registry", "HKEY_LOCAL_MACHINE\\SOFTWARE\\QUERIX\\Q4GL\\QUERIXDIR")
system.environment	environment variable name	CALL fgl_getproperty("system.environment", "TEMP")
system.network	"Ipaddress"	can get parameters of both server and client (by default, client): CALL fgl_getproperty("gui","system.network","Ipaddress") CALL fgl_getproperty("server","system.network","Ipaddress") The same results can be achieved in this way: CALL fgl_getenv("QX_CLIENT_IP") CALL fgl_getenv("QX_SERVER_IP")
system.network	"hostname"	can get parameters of both server and client (by default, client): CALL fgl_getproperty("gui","system.network","hostname") CALL fgl_getproperty("server","system.network","hostname") The same results can be achieved in this way: CALL fgl_getenv("QX_CLIENT_HOST") CALL fgl_getenv("QX_SERVER_HOST")
system	"username"
user	user property name	CALL fgl_getproperty("user.hello", "myoption")
