void con_attach	(	Con *	con,

Attaches the given container to the given parent.

This happens when moving a container or when inserting a new container at a specific place in the tree.

ignore_focus is to just insert the Con at the end (useful when creating a new split container around some containers, that is, detaching and attaching them in order without wanting to mess with the focus in between).

int con_border_style ( Con * con )

Use this function to get a container’s border style.

This is important because when inside a stack, the border style is always BS_NORMAL. For tabbed mode, the same applies, with one exception: when the container is borderless and the only element in the tabbed container, the border is not rendered.

For children of a CT_DOCKAREA, the border style is always none.

bool con_fullscreen_permits_focusing ( Con * con )

Returns true if changing the focus to con would be allowed considering the fullscreen focus constraints.

Specifically, if a fullscreen container or any of its descendants is focused, this function returns true if and only if focusing con would mean that focus would still be visible on screen, i.e., the newly focused container would not be obscured by a fullscreen container.

In the simplest case, if a fullscreen container or any of its descendants is fullscreen, this functions returns true if con is the fullscreen container itself or any of its descendants, as this means focus wouldn't escape the boundaries of the fullscreen container.

In case the fullscreen container is of type CF_OUTPUT, this function returns true if con is on a different workspace, as focus wouldn't be obscured by the fullscreen container that is constrained to a different workspace.

Note that this same logic can be applied to moving containers. If a container can be focused under the fullscreen focus constraints, it can also become a parent or sibling to the currently focused container.

void con_move_to_workspace	(	Con *	con,
		Con *	workspace,
		bool	fix_coordinates,
		bool	dont_warp,
		bool	ignore_focus
	)

Moves the given container to the currently focused container on the given workspace.

The fix_coordinates flag will translate the current coordinates (offset from the monitor position basically) to appropriate coordinates on the destination workspace. Not enabling this behaviour comes in handy when this function gets called by floating_maybe_reassign_ws, which will only "move" a floating window when it already changed its coordinates to a different output.

The dont_warp flag disables pointer warping and will be set when this function is called while dragging a floating window.

If ignore_focus is set, the container will be moved without modifying focus at all.
