public class DockPane extends Container:

Widget

└ Container

└ DockPane

Retractable and resizable side panel hosted by a DockWorkspace.

A pane owns a content widget, a logical side and a preferred dock size. The workspace displays at most one expanded pane per side; collapsed panes remain reachable through their side DockBar button. The pane itself is headerless: the hosted content owns its title area, while the close affordance is painted as a lightweight overlay when the pointer is inside the pane. Its rounded contour clips the hosted content by default; cornerRadius or the DockPane KSS selector can customize that contour.

workspace = DockWorkspace()
pane = DockPane("Projects", ProjectExplorerPane(), DockSide.LEFT, "assets/icons/project-explorer.svg")
pane.dockSize = 320
workspace.addPane(pane)
