Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| User-controlled layout | Choose user-controlled layout when users choose the arrangement, visibility, or order of workspace regions around the same task object. | Changing layout rearranges regions but does not change the active record, dataset, filters, columns, sort, density, theme, or saved view unless the user explicitly chooses those changes. | Supports accessible pane resizing, collapse, restore, orientation, and keyboard behavior used inside layout-changing workspaces. |
| Window splitter | Choose window splitter when adjacent panes are both part of the same durable workspace and users need control over their relative sizes. | The splitter separates two named panes and communicates which pane size its value represents. | APG defines window splitter behavior, role separator use, value attributes, orientation, keyboard resizing, collapse or restore, and pane naming. |
