This attribute can be used on a class deriving from QueryListBlock to display in query builder mode a special block that will propose a fixed set of values when clicked.
The following example shows how to display a custom list block for the shader filter block.
[QueryListBlock("Decal", "Shader", "shader")] class ShaderDecalBlockList : QueryListBlock { public ShaderDecalBlockList(IQuerySource source, string id, string value, QueryListBlockAttribute attr) : base(source, id, value, attr) { } public override IEnumerable<SearchProposition> GetPropositions(SearchPropositionFlags flags = SearchPropositionFlags.None) { yield return new SearchProposition(category: null, "HDRP Decal", "Decal", icon: GetShaderIcon() as Texture2D); yield return new SearchProposition(category: null, "URP Decal", "DecalURP", icon: GetShaderIcon() as Texture2D); } }
| category | Category. |
| id | Filter id of the block. |
| ids | A set of IDs for which the list block will be displayed. |
| name | Displayed name of the block. |
| op | Default operator assigned to the filter when the value changes. |
| type | The list block type is used to get the the icon to be displayed instead of the block name. |
| QueryListBlockAttribute | Register a list block for a given filter. |
