Finding the role of a certain client in order to enable a physical pushbutton

[pturmel]

I would split this requirement into two separate indicators, one for determining whether a client is running on the gateway or not, the other checking the required role.

I would implement the first requirement with a client startup script that interrogates the local network interfaces and checks for the mac IDs of the gateway (those could be hard-coded into the script). And then writes the result to a boolean tag like [Client]RunningInGateway. Such script only runs in a client, so designers would be excluded by default. (Note, a designer could just toggle that boolean to get around this, but you can't really stop anyone with designer privileges from going around your security.) This script might help you:

Mobile Client MAC Address

In a real Vision client, you can obtain the local MAC addresses with the following script: from java.net import NetworkInterface # Get list of local mac address as strings def myMacIds(): macs = [ni.hardwareAddress for ni in NetworkInterface.getNetworkInterfaces() if ni.hardwareAddress] return [":".join(["%02x" % (b & 0xff) for b in mac]) for mac in macs] Also, again in a real Vision client, you can obtain the outbound network interface and the corresponding local IP address the clien…

I would implement the latter requirement as a boolean custom property, IsPrivileged perhaps, on the window containing the restricted pushbuttons, bound to the hasRole() expression function.

The pushbuttons in question would have the expression {[Client]RunningInGateway} && {Root Container.IsPrivileged} bound to their enable property.
