Virtual Terminal Input List size manipulation

[jens-seiersen]

Hi,

I am continuing my journey into the wonders of Virtual Terminals.

When I have an Input List, that I have set up in ISO Designer, is there any way to make the choice values dynamically? I mean, when my program starts up, can it retrieve some choices from a configuration and then only show those choices? I was thinking that I could have, maybe 8 strings attached to the Input List, then if the configuration is only 3 choices, then I could "hide" the last 5. There is a methon on the InputList object: set_number_of_list_items(value) but I am not sure if that works.

The inputlist size cannot be changed dynamically.

Number of object references to follow. The size of the list can never exceed this number and this attribute cannot be changed.

To limit the item count you can try to replace some items with NULL objects:

When a list item has an Object ID of NULL it is considered an invisible object. It does not occupy a
position in the displayed list and cannot be selected by the operator. However, it is still counted when
determining list indexes and maintains its position in the list even though it is not visible to the operator.

Thanks for the answer. Although it makes my work a little bit more difficult.
I found the method: send_change_list_item() in isobus_virtual_terminal_client.hpp and that appears to do what I want. I can set unused items to "not-there" with: isobus::NULL_OBJECT_ID.
Thanks again for your help!
