41 * the first configured one. Needs to be called before reorder_bindings() so
42 * that the config-file order is used, not the i3-internal order.

48 * Returns a pointer to a new workspace in the given output. The workspace
49 * is created attached to the tree hierarchy through the given content

113 * Assigns the given workspace to the given screen by correctly updating its
114 * state and reconfiguring all the clients on this workspace.

165 * the same orientation as the workspace and then changing the workspace

172 * Called when a new con (with a window, not an empty or split con) should be
173 * attached to the workspace (for example when managing a new window or when
174 * moving an existing window to the workspace level).
176 * Depending on the workspace_layout setting, this function either returns the
177 * workspace itself (default layout) or creates a new stacked/tabbed con and

184 * Creates a new container and re-parents all of children from the given
187 * The container inherits the layout from the workspace.
