26 * Returns a pointer to the workspace with the given number (starting at 0),

38 * workspace web”), so that when an output needs a workspace, i3 can start with
39 * the first configured one. Needs to be called before reorder_bindings() so
40 * that the config-file order is used, not the i3-internal order.
43 void extract_workspace_names_from_bindings(void);
46 * Returns a pointer to a new workspace in the given output. The workspace
47 * is created attached to the tree hierarchy through the given content

55 * multi-monitor environments, as they can have multiple currenlty active

111 * Assigns the given workspace to the given screen by correctly updating its
112 * state and reconfiguring all the clients on this workspace.
114 * This is called when initializing a screen and when re-assigning it to a

163 * the same orientation as the workspace and then changing the workspace
167 void ws_force_orientation(Con *ws, orientation_t orientation);
170 * Called when a new con (with a window, not an empty or split con) should be
171 * attached to the workspace (for example when managing a new window or when
172 * moving an existing window to the workspace level).
174 * Depending on the workspace_layout setting, this function either returns the
175 * workspace itself (default layout) or creates a new stacked/tabbed con and
179 Con *workspace_attach_to(Con *ws);
182 * Creates a new container and re-parents all of children from the given
185 * The container inherits the layout from the workspace.
