Default List With Icon

There is a very easy way to include an icon in an automatically generated list.

The only thing to do is to add an item (property or concept) to the node structure that contains the data of the list (mostly …TR…) and assign the name of the icon to it.

This property should be of type string, exist in client and be visible and MUST have the Internal Type 84 (List Icon). The icon can be either an icon provided by Meta4, e.g. “PERSON” (as in the screen shot) or an image located in the Images folder.

Note: Images folder defined in: HKEY_LOCAL_MACHINE\SOFTWARE\Meta4\Mind\_3.X\Build\YourBuild\CLIENT\CLIENT\Presentation_Runtime_Vars\ImagesFolder; this key contains the path within double quotes (e.g. “C:\Meta4\Images\”).
