Jaotuspaneel

Jaotuspaneel is a user interface container that divides an application window into two or more resizable panes separated by a draggable divider. The component typically supports both horizontal and vertical orientations, allowing users to adjust the amount of space allocated to each pane by dragging the divider. Some implementations also offer min and max sizes, collapsible panes, and persistence of pane proportions between sessions.

In standard GUI toolkits, a jaotuspaneel is often implemented as a split pane or paned window. Common features include a draggable divider, keyboard accessibility for moving the divider, and the ability to nest multiple jaotuspaneel instances to create complex layouts. Designers may provide additional options such as divider thickness, whether panes snap to certain ratios, and how resizing interacts with dynamic content.

Across platforms, jaotuspaneel appears in various forms: in Java Swing as JSplitPane, in Qt as QSplitter, in Windows frameworks as a SplitContainer, and in GTK as Paned. In web development, equivalent behavior is achieved with CSS layouts (grid or flex) combined with JavaScript to implement a draggable handle and to manage pane sizes.

Common use cases include IDEs with a code editor and a project explorer, file managers comparing side-by-side views, dashboards with resizable panels, and editors that allow side-by-side viewing of documents. Considerations when using a jaotuspaneel include ensuring usable minimum sizes, maintaining accessibility with keyboard and screen readers, and designing responsive behavior for different screen sizes.
