In xdesigner, resources are typically laid out in pages within the relevent resource panel, since usually any given widget will have too many resources to display conveniently at a given time.
For the Motif widgets, resources are assigned to the various pages of a resource panel according to logical type. For user-defined widgets, xdesigner will attempt by default to apply the same rules for resource panel page layout. A catch-all page 'misc' is provided for any resource which xdesigner cannot type - that is, the resource is not derived from known Motif types.
This behaviour might not be what you want. The widget resources might well be partitionable into logical groups which bear no relation to the Motif groupings.
The resource page dialog allows you to specify exactly where each resource of a user-defined widget is to be allocated. It contains a list, by default populated with the default set of pages, together with fields for changing the contents of the page list.
Either select a page from the list provided, or add/delete new pages to the list as required.
