/atom/movable/maptext_manager 
Maptext manager atom/movables govern displaying maptext over single parent atom. To this end, they track the outermost movable
of the parent atom, and relocate to the outermost loc if possible. To display maptext to a client, the list of maptext holders
indexed by their associated clients is queried for the maptext holder associated with that client, and instructed to add a line.
Vars | |
| maptext_holders_by_client | A list of maptext holders belonging to this maptext manager, indexed by their associated clients. |
|---|---|
| parent | The atom that this maptext manager belongs to. |
| registered | Whether this maptext manager is registered to the XSIG_OUTERMOST_MOVABLE_CHANGED complex signal. |
Procs | |
| add_maptext | Adds a line of maptext to the maptext holder associated with the specified client, displaying the maptext over the parent atom. |
| notify_empty | Notifies this maptext manager that the maptext holder of the specified client is empty. If all maptext holders are empty, the XSIG_OUTERMOST_MOVABLE_CHANGED complex signal is unregistered. |
| notify_nonempty | Notifies this maptext manager that a maptext holder is nonempty, requiring it to register the XSIG_OUTERMOST_MOVABLE_CHANGED complex signal if not already done so. |
| update_outermost_movable | Update the loc of this maptext manager to specified new outermost movable. Used with XSIG_OUTERMOST_MOVABLE_CHANGED. |
Var Details
maptext_holders_by_client
A list of maptext holders belonging to this maptext manager, indexed by their associated clients.
parent
The atom that this maptext manager belongs to.
registered
Whether this maptext manager is registered to the XSIG_OUTERMOST_MOVABLE_CHANGED complex signal.
Proc Details
add_maptext
Adds a line of maptext to the maptext holder associated with the specified client, displaying the maptext over the parent atom.
notify_empty
Notifies this maptext manager that the maptext holder of the specified client is empty. If all maptext holders are empty, the XSIG_OUTERMOST_MOVABLE_CHANGED complex signal is unregistered.
notify_nonempty
Notifies this maptext manager that a maptext holder is nonempty, requiring it to register the XSIG_OUTERMOST_MOVABLE_CHANGED complex signal if not already done so.
update_outermost_movable
Update the loc of this maptext manager to specified new outermost movable. Used with XSIG_OUTERMOST_MOVABLE_CHANGED.
