- Ask the compositor to make a toplevel obey the app_role and, depending
- on the role, to use the the x and y values as initial positional values.
- The x and y values would only make sense for certain roles.
+ Ask the compositor to make a top-level window obey the 'app_role' enum
+ and, depending on that role, to use some of the arguments as initial
+ values to take into account.
+
+ Note that x, y, bx, by, width and height would only make sense for the
+ pop-up role, with the output argument being applicable to all the roles.
+ The width and height values define the maximum area which the
+ top-level window should be placed into. Note this doesn't correspond to
+ top-level surface size, but to a bounding box which will be used to
+ clip the surface to, in case the surface area extends that of this
+ bounding box. Both of these values need to be larger than 0 (zero) to be
+ taken into account by the compositor. Any negative values for the width
+ and height will be discarded.
+
+ The x and y values will serve as the (initial) position values.
+ The bx and by values are the top-left x and y value of the bounding box.
+ Any clipping happening to the bounding box will not affect the surface
+ size or the position of the underlying surface backing the top-level
+ window. The bx and by values, like the positional values, could be
+ both set to zero, or even negative values. The compositor will pass
+ those on without any further validation.
+
+ The initial position values and the bounding rectangle will still be
+ in effect on a subsequent activation request of the 'app_id', assuming
+ it was previously de-activated at some point in time.
See xdg_toplevel.set_app_id from the xdg-shell protocol for a
description of app_id.
