/**
* Usage:
* 1. foreign-toplevel
* Prints a list of opened toplevels
* 2. foreign-toplevel -f <id>
* Focus the toplevel with the given id
* 3. foreign-toplevel -a <id>
* Maximize the toplevel with the given id
* 4. foreign-toplevel -u <id>
* Unmaximize the toplevel with the given id
* 5. foreign-toplevel -i <id>
* Minimize the toplevel with the given id
* 6. foreign-toplevel -r <id>
* Restore(unminimize) the toplevel with the given id
* 7. foreign-toplevel -c <id>
* Close the toplevel with the given id
* 8. foreign-toplevel -m
* Continuously print changes to the list of opened toplevels.
* Can be used together with some of the previous options.

<interface name="zwlr_foreign_toplevel_manager_v1" version="1">
<description summary="list and control opened apps">
The purpose of this protocol is to enable the creation of taskbars
and docks by providing them with a list of opened applications and
letting them request certain actions on them, like maximizing, etc.
After a client binds the zwlr_foreign_toplevel_manager_v1, each opened
toplevel window will be sent via the toplevel event
</description>
<event name="toplevel">
<description summary="a toplevel has been created">
This event is emitted whenever a new toplevel window is created. It
is emitted for all toplevels, regardless of the app that has created
them.
All initial details of the toplevel(title, app_id, states, etc.) will
be sent immediately after this event via the corresponding events in
zwlr_foreign_toplevel_handle_v1.
</description>
<arg name="toplevel" type="new_id" interface="zwlr_foreign_toplevel_handle_v1"/>
</event>
<request name="stop">
<description summary="stop sending events">
Indicates the client no longer wishes to receive events for new toplevels.
However the compositor may emit further toplevel_created events, until
the finished event is emitted.
The client must not send any more requests after this one.
</description>
</request>
<event name="finished">
<description summary="the compositor has finished with the toplevel manager">
This event indicates that the compositor is done sending events to the
zwlr_foreign_toplevel_manager_v1. The server will destroy the object
immediately after sending this request, so it will become invalid and
the client should free any resources associated with it.

<description summary="an opened toplevel">
A zwlr_foreign_toplevel_handle_v1 object represents an opened toplevel

Each toplevel has a list of outputs it is visible on, conveyed to the
client with the output_enter and output_leave events.

<description summary="all information about the toplevel has been sent">
This event is sent after all changes in the toplevel state have been

to be seen as atomic, even if they happen via multiple events.

<request name="close">
<description summary="request that the toplevel be closed">
Send a request to the toplevel to close itself. The compositor would
typically use a shell-specific method to carry out this request, for
example by sending the xdg_toplevel.close event. However, this gives
no guarantees the toplevel will actually be destroyed. If and when
this happens, the zwlr_foreign_toplevel_handle_v1.closed event will
be emitted.

<request name="set_rectangle">
<description summary="the rectangle which represents the toplevel">
The rectangle of the surface specified in this request corresponds to
the place where the app using this protocol represents the given toplevel.
It can be used by the compositor as a hint for some operations, e.g
minimizing. The client is however not required to set this, in which
case the compositor is free to decide some default value.
If the client specifies more than one rectangle, only the last one is
considered.
The dimensions are given in surface-local coordinates.
Setting width=height=0 removes the already-set rectangle.

<description summary="this toplevel has been destroyed">
This event means the toplevel has been destroyed. It is guaranteed there
won't be any more events for this zwlr_foreign_toplevel_handle_v1. The
toplevel itself becomes inert so any requests will be ignored except the
destroy request.
</description>
</event>
<request name="destroy" type="destructor">
<description summary="destroy the zwlr_foreign_toplevel_handle_v1 object">
Destroys the zwlr_foreign_toplevel_handle_v1 object.
This request should be called either when the client does not want to
use the toplevel anymore or after the closed event to finalize the
destruction of the object.
